global supply chain issues

Supply Crunch Continues to Push Prices Suppliers are Charging Businesses

As we wrote last year, the global supply chain crunch will continue to impact pricing, lead times and deliverables well into 2022 and beyond. Prices paid to U.S. producers posted a record annual increase of almost 10% in November, a surge that will sustain a pipeline of inflationary pressures well into 2022.

The producer price index for final demand increased 9.6% from a year earlier and 0.8% from the prior month, Labor Department data showed in December. Both advances topped economists’ forecasts.

Materials costs have risen rapidly this year amid transportation bottlenecks, robust demand, and labor constraints. Many businesses have successfully passed those added costs on to customers through higher prices, and the latest report suggests additional consumer price increases in the coming months.

Manufacturing companies have all had to adjust to the realities brought on by the global supply crunch, and here at Cass Precision Machining we are collaborating with our partners as much as possible, doing the best we can to alleviate costs and concerns for our customers. This partner collaboration includes daily logistics, tracking materials via spreadsheets, and shuffling and prioritizing schedules etc. and communicating as often as possible with our customers.

According to the Wall Street Journal, the higher-than-expected producer-price numbers suggest that consumer inflation, which hit a nearly four-decade high of 6.8% in November, will stay elevated into 2022 as price pressures persist. The index, which generally reflects supply conditions in the economy, rose 0.8% from October, an acceleration from the 0.6% gain in each of the previous three months. Higher prices for energy, wholesale food, and transportation and warehousing contributed to the pickup in inflation.

“This is a testament to the fact that inflation continues to broaden out,” said Stephen Stanley, chief economist at Amherst Pierpont, in the WSJ article.

Persistently high prices in large part reflected clogged supply chains, as manufacturers scrambled to keep up with unusually strong consumer demand. The rise in prices of goods continued to outpace that for services, as consumer spending on goods remains elevated, while that on services is up just slightly from pre-pandemic levels.

Prices for good, excluding food and energy, climbed 0.8% in November from October, faster than the 0.6% increase the previous month. The service index advanced 0.7% on the month, up from 0.2% in October, driven in part by a pickup in hotel room rates and airfares.

According to Reuters, trillions of dollars in COVID-19 pandemic relief from governments across the globe fueled demand for goods, leaving supply chains overstretched. The normalization of economic activity has also juiced demand for services, with the delivery of some being hampered by worker shortages, driving up prices.

The easing of inflation for goods used to make other products, though still high, signaled that producer-price inflation is nearing its peak, said Gus Faucher, chief economist at PNC, in the Wall Street Journal. “PPI inflation will slow in 2022 as prices for energy and other raw materials decline thanks to greater production, weaker demand, and a gradual waning in supply chain problems,” said Faucher. “But PPI inflation will remain above its long-run levels due to continued strong demand for some goods and services and higher wages.”

At Cass Precision Machining we continue to partner closely with our customers to manage the challenges around material availability, material price, delivery needs and shipping.  We are committed to developing creative solutions to optimize customer success.

Supply Chain Shortages

Assessing Supply Chain Shortages in 2022

China’s Battle with Decarbonization Poses Business Risks

In Assessing Supply Chain Shortages in 2022, Climate Change is a major factor in the equation.  In August UN Secretary-General Antonio Guterres called the report released by the UN’s Panel on Climate Change, “A code red for humanity.”  The report says that humans are unequivocally warming the planet and the results will be more heat waves, droughts, flooding, and hurricanes. The impact of all of that on global businesses is infinite and its ripples will impact business commerce across the globe.

In a much-anticipated announcement at the United Nations General Assembly in September, China President Xi Jinping stated that his country would peak carbon emissions by 2030 and aim to achieve carbon neutrality by 2060.

Regardless of ongoing trade tension between the two countries, meetings between the countries in the spring positively affirmed U.S. and Chinese cooperation in bolstering the implementation of the Paris Agreement and underscored the importance of ambitious climate action by the world’s largest greenhouse gas (GHG) emitters.

Supply Chain Challenges

For thousands of U.S. companies that have supply chains or operations in China, particularly companies that have not yet developed sufficiently rigorous greenhouse gas emission reduction goals, the Chinese national response to climate change represents complicated new opportunities and challenges.

Since Xi’s announcement was made, multiple industries and municipal and regional governments have begun increasing action related to decarbonization. These actions, along with past precedents in pollution control in China, provide guidance for how companies might consider preparing for business risks and disruption related to China’s quest for decarbonization.

As the number and scope of binding regulations for reducing carbon emissions increase in the coming months and years, it remains essential for companies with supply chains or operations in China to stay abreast of emerging business risks driven by the country’s timelines for emission reductions. 

According to an August article in GreenBiz, emerging business risks and opportunities will include:

  • Sourcing (through the need to qualify lower-carbon raw materials)
  • Process (upgrading production processes and equipment)
  • Emission controls (carbon emission reductions and capture)
  • Reporting requirements, both to regulators and to the finance sector
  • Access to capital, particularly domestic Chinese capital
  • Adverse reputational impact in China arising from ineffective or incomplete response to Chinese requirements
  • Industrial structure adjustments including replacing industrial processes and equipment and the elimination of outdated industries; and economic adjustments, such as a carbon tax

Shipping Problems

Just last week, Reuters posed the following question: What happens when the market of last resort, the London Metal Exchange (LME), runs out of metal? The 144-year-old exchange, which sets benchmark prices for the global industrial metal markets, has always prided itself on its role as ultimate buyer and ultimate seller of physical metal.

Total registered LME inventory has fallen by almost 600,000 metric tons since the start of the year. Stocks of all metals stand at 1.469 million metric tons, the lowest since 2008.  The strength of the post-COVID manufacturing recovery, first in China and now in the rest of the world, has impacted not just aluminium but all of the LME metals to varying extents.

Supply-chains, by contrast, are stressed by continued disruption in the global shipping sector, where container rates remain high and many ports, particularly U.S. ones, log-jammed.

How To Decarbonize?

The world needs more aluminum to go green.  But the smelters that produce aluminum use huge amounts of power and account for around 2% of all man-made emissions each year. Squaring that carbon circle is not going to be easy for China or the global market.

Welcome to aluminum’s decarbonization paradox.

Aluminum market rallies during the year were rooted in China’s own supply-chain tensions. Output curbs following energy restrictions are proliferating as provinces scramble to meet mandated energy efficiency targets.

The 10 aluminium producers participating in the CNIA (China Nonferrous Metals Industry Association) meeting committed to “continue to ensure supply and stabilize market expectations”. Only, however, if their power-hungry smelters have sufficient supplies of electricity. Aluminium is produced by electrolysis not by blasting it in a furnace. No power, no aluminium. And power in China is becoming a problem.

Aluminium curtailments earlier this year in Inner Mongolia were modest but a sign of things to come as the coal-dependent province tried to meet new quarterly dual-control targets for energy usage and efficiency. The province of Guangxi, another laggard in the energy league, last month ordered smelters to reduce run-rates to preserve power over peak demand periods.

Since China is by far the world’s largest producer of aluminum, both at a raw metal and semi-manufactured product level, this collective powering-down places a big question-mark over global supply. A market that has lived with Chinese over-supply for two decades is starting to price in a very different future. The country remains a large exporter of aluminum in the form of semi-manufactured products, which is starting to look anomalous as the huger for commodity-grade metal grows.

According to Reuters, stresses on China’s power system have turned the world’s largest supplier of aluminum into a regular net importer of primary metal. China’s problem today could be the rest of the world’s problem tomorrow. Estimates that the world will need another 25 million metric tons of primary metal production to meet an expected 80% rise in demand by 2050, fueled by the demands of decarbonization. Building that capacity while simultaneously “greening” existing capacity in a world that needs ever more renewable power is the conundrum facing the global aluminum industry.

Supply Crunch Cass

How to Find Manufacturing Success During the Post-Covid Supply Crunch

As the global economy slowly recovers from the impact of the COVID-19 pandemic, the worldwide supply crunch is intensifying, spreading from one country to another and from one industry to another.

Breaking Down the Supply Crunch

When the pandemic spread in the spring of 2020, there was a lot of panic buying by consumers who were led to believe there would be shortages in things like toilet paper, hand sanitizer, and disinfectant wipes. Fast forward 15 months, and it’s companies that are stockpiling, buying more raw materials than they need in an attempt to keep up with rapidly recovering demand. This panic buying is causing a shortage in raw materials, including copper, iron ore, steel, wood, semiconductors, plastics, cardboard, etc. As a result, there is a “supply crunch” in nearly every industry, with inventories of seemingly every raw material around the world running low.

What The Experts Are Saying

Economists and business executives say those supply-chain disruptions, key labor shortages, and resurgent demand will persist through the end of 2021, if not longer.

“Supply shortages are affecting almost every industry,” said Michael Pearce, Senior U.S. Economist at Capital Economics. “What started out as a shortage of semiconductors affecting mostly the auto industry is now a shortage of basically everything, including lumber, metals, and plastics.”

According to Reuters, “U.S. factory activity gathered speed in early May amid strong domestic demand, but backlogs of uncompleted work are piling up as manufacturers struggle to find raw materials and labor, boosting costs for both businesses and consumers.”

Suffice to say that with all of the raw material and supply shortages in North America, it is hardly “business as usual” in manufacturing. According to the Wall Street Journal, the squeeze on U.S. businesses shows little sign of letting up, particularly in the manufacturing sector.

“It turns out it’s a heck of a lot easier to create demand than it is to—you know, to bring supply back up to snuff, Fed Chairman Jerome Powell said in June. So what we know is that there are global supply shortages that are impacting manufacturing and that the supply crunch will have medium- and long-term impacts.

Work With Your Manufacturer

Yes, the pipelines are seeing logjams; there’s no way around that. Understanding that issue, smart businesses will work with their manufacturing partners to make the best of their situation.

  • Maintain Regular Communication—nobody likes surprises, especially when they negatively impact their workflow. More communication with your supplier helps to limit surprises. Remember that everyone is facing a supply crunch. The more your supplier knows exactly what you’re looking for and you understand their capabilities, the less you’ll be hit with surprises. This doesn’t exactly mean that the squeaky wheel gets the grease. Your supplier loves having your business, but they don’t want to hear from you 20 times a day. Be respectful of their situation—remember that your supplier is getting dozens of emails and phone calls every day. Be concise, don’t send a 15-paragraph email when five sentences will do. If your orders are consistent, it’s easier for your supplier to manage your supply.
  • Collaboration and Preparation—Try to establish weekly or bi-weekly meetings to troubleshoot the problems you face because of the supply chain crunch. Be as resourceful as possible and always be respectful of your supplier. Tight collaboration enables organizations to better avoid risks, identify problems early and resolve issues quickly. Many companies, for example, proactively alert suppliers immediately when demand and production changes are likely.
  • Maintain Flexibility—The pandemic crunch is very real when it comes to the supply chain. Companies having success are learning to become innovative, developing recovery plans, and looking at possible workarounds in terms of substituting materials (if and when it makes sense). Supply chain and procurement teams have been faced with a delicate but decisive balancing act. They must plot a route through the immediate and future challenges that draw on meaningful insight based on high-quality data. This will enable them to build flexibility into their cost base and transform costs – rather than simply cut them – to come back fighting when the time is right. Those who have already started to invest in new technologies to drive insight and action in the supply chain have a head start over the competition.

Maintain regular communication with your supplier so that it’s not a surprise to either side when changes in orders occur. Collaborate with your dealer and troubleshoot problems caused by the supply crunch before they can have a big impact. Recovery plans and workarounds are crucial to keeping your workflow flexible and agile.

industrial rapid prototyping

Industrial Rapid Prototyping With CNCs

Companies need to develop and introduce new products faster to remain competitive in this fast-moving modern-day consumer market. Since faster product development and technology innovation are key to a company’s success, rapid prototyping becomes the most important element of new product development.

Industrial rapid prototyping bridges the gap between concept design and manufacturing for production. The prototyping process is also an opportunity for company engineers to build physical parts that can be used to test functionality in equipment, failure rates and manage production costs prior to full-scale manufacturing.  By detecting problems in the preliminary stage, companies save time and money and create confidence that they are not releasing substandard products to customers.

The Benefits of Using CNC Machining for Industrial Prototypes

The first thing most people think of when they hear the term “CNC machining” is large-scale manufacturing. It might surprise some people to learn how effective CNC machining is in creating prototypes. When developing prototypes in the manufacturing world, many different processes are available, but CNC machining can be one of the best.

CNC machines are ideal for prototyping because the design of the CNC machine itself includes three key elements for prototyping:

1. Speed

The maximum feed and rapid rates can exceed 2,300 inches per minute (ipm), faster than three feet per second.

2. Accuracy

CNCs can hold very tight tolerances (.0001 +/-tolerance)

3. Flexibility

Almost any material can be used in a CNC machine depending on the application (aluminum, brass, copper, steel, titanium, and plastics)

CNCs also have another big benefit in prototyping which is repeatability. CNCs can repeat all process steps over and over, from part to part, and can be programmed to make slight variations in prototype parts for testing and evaluation. 

How Cass Precision Machining is Leveraging CNCs for Rapid Prototyping

Cass started its C-RPM business unit in late 2020 to help customers achieve the following objectives:

  • Faster new product development—prototyping is crucial in the process of creating successful products because it speeds up the product development process
  • Early-stage design and concept validation of form, fit, and function of the design
  • Final stage product verification against the technical requirement and business objective
  • Allows for functionality testing to test the goals of the concept and to finalize specifications
  • Prototypes give the client, customer, end-user hands-on user experience to get and give feedback

Cass’s expertise in turn parts and CNC machining created the right combination to position Cass for success in prototyping.  In fact, the CNC mill is one of the most common tools to see in a prototyping lab, and Cass added both a mill and a lathe to its prototyping cell. These CNC mills are reliable and flexible machines allowing for complex features, like threaded holes, deep pockets, and 3D surfaces.

Today, Cass partners with its customers to help shape the initial prototypes into design-for-manufacturing parts so the finished parts can easily transition from concept to full production.  Cass welcomes current and potential customers to see the process and the capabilities of the CNCs in industrial rapid prototyping.

Industrial Manufacturing

Understanding Industrial Manufacturing | Cass Precision Machining

The industrial manufacturing industry is responsible for the fabrication of products intended for industrial use from raw materials. When asking the question, “what is industrial manufacturing?” one has to look at the output itself (the products produced) which ranges from large machinery like bulldozers and cranes to smaller products such as wheelchairs and circuit boards. No matter what type of machinery is used, industrial manufacturing is crucial in producing many of the goods and services vital to any economy in a cost-efficient and timely manner.

Equipment Segments Produced

Equipment used in industrial manufacturing can be grouped into seven different segments. Agricultural, construction, and mining machinery; industrial machinery; commercial and service machinery are all special-purpose machinery designed for a specific industry. The four other segments include machinery used by all sectors: ventilation, heating and cooling equipment, metalworking equipment, engine-related equipment, and other general-purpose machinery.

How do companies separate themselves when it comes to industrial manufacturing? In one word: efficiency. The more efficiently a company can produce a product, the more products it can make at a lower cost, which results in higher profit margins. A major trend in this industry is using increasingly high-tech production techniques. Firms are introducing more technology in response to pressure from both domestic and foreign competitors. Robotics, computers, and programmable equipment are common, resulting in increased productivity with more efficiency and a decreased need for labor.

What’s the Difference Between Industrial Manufacturing and Custom Manufacturing?

The manufacturing industry is made up of two core branches—industrial and custom manufacturing. While there are some similarities between the two, each one has its different processes and priorities. As a result, the role their ERP (enterprise resource planning) platforms play within the organizations is naturally different.

In industrial manufacturing, products are configured to order. Customers can order a stock product, and while they have the flexibility to alter certain features of the order, they are still limited to a catalog of pre-designed products. In custom manufacturing, unique products are designed or engineered to order. Custom manufacturers place a premium on ERP systems that bring flexibility and agility. Industrial manufacturers, on the other hand, covet operational efficiency. Unlike in custom manufacturing, where every product is different, industrial manufacturers benefit from predictability and repetition throughout the process.

Pandemic Recovery

Like nearly every walk of life, industrial manufacturing was severely impacted by COVID-19. The pandemic posed sudden and drastic challenges as demand for products fell while others increased, and geopolitical trade conditions severely disrupted access to markets, distribution channels, and suppliers. The speed of recovery for industrial manufacturing is highly dependent on the rate of recovery for supply and demand.  While customer orders soared for many companies the backlog of material availability has continued and costs have risen.

Companies in this industry will need to utilize key market data to inform long-term strategic decisions based on shifts in demand and their own downstream impacts.  Creativity, collaboration and communication will be key to the success of many industrial manufactures.

Cass provides C-RPM material consulting, machining expertise, and coordinated services to deliver the finished parts customers are looking for. Your C-RPM team is ready to provide rapid responses to your prototype parts needs with part size ranges from up to eight inches in diameter to 26 inches in overall length.

Opening our C-RPM service adds another key step in Cass’s evolution of providing a broader range of solutions for our customers,” said Jim Garvin, Cass’s President. “This new business unit adds another facet to supporting clients’ supply chain needs over the full life cycle of their parts.”

The C-RPM cell can handle a wide range of materials, including alloys, carbon, stainless steel, titanium, aluminum, brass, bronze, machinable plastics, and more. CNC milling and complex turning capability are the cornerstones of the C-RPM unit.

Finishing services include anodizing, heat treating, plating, shot peening, custom packaging, light assembly, and more.

“At Cass, we’re proud of our long tradition of listening to our customers and taking the appropriate actions as a reliable partner that our clients can trust,” said Garvin. “Cass-Rapid Proto Machining lines up with the growing needs of clients and enables us to support more creative design solutions.”

Cass Precision Machining has made a concerted effort to ramp up our C-RPM initiatives by investing in two machines that help us turn out quality parts in a timely fashion.

The Tsugami M08SY Turning Center with Y-axis allows Cass to perform highly complex machining, such as turning, drilling, boring, cross-drilling, and CNC milling. The main and sub-spindle are equipped with integral built-in spindle motors, which minimize vibration and provide superior accel/decel for heavy-duty cutting and fine finishing.

The Doosan 5700 Mill is part of a series that offers larger cutting space by 6%, bigger table sizes by 14%, and heavier loads by 25% while maintaining the same overall footprint as the previous generation. The new DNM series features direct-coupled, thru-coolant type spindles as standard, providing 8,000 rpm (15/11 kW) and 12,000 rpm (18.5/11 kW). Vibration and noise are greatly reduced during high-speed operations, and thermal displacement is also improved. The direct-drive spindles also contribute to faster accel/decel rates, and tool change times have also been optimized to reduce non-cutting time.

Send our C-RPM team your prints, or we can discuss your design ideas online. Our prototype team can handle a wide range of materials as mentioned above—challenge us with your material requirements!

C-RPM Machining—CNC Milling and Live Tool Lathe machines are the cornerstones of the cell.

cass air force project

Cass Does its “Part” for the Commemorative Air Force

Sometimes a job is about far more than the bottom line.

Cass Precision Machining was honored to recently volunteer their time, material, and machines to produce a part for the Commemorative Air Force Airbase, located in Mesa, Arizona.

The Commemorative Air Force are flight museums dedicated to the education and enjoyment of present and future generations of Americans with a fleet of historic aircraft that recreate, remind, and reinforce the lessons learned from the defining moments in American military aviation history.

With a mission to educate, inspire, and honor through flight and living history experiences, the Commemorative Air Force offers flights to museum visitors four days a week in various planes, including the B-25 “Maid in the Shade” bomber, built in early 1944. With so many flights under its belt, the B-25 bomber had worn out its bushings on the arms for the Cowell flaps—parts that open during takeoff to allow air to flow through the engine and close during landings.

Cass Precision Machining was more than happy to volunteer their time and expertise to get the B-25 bomber back up in the air, flying more safely than ever. Airbase Arizona offers a rare and exciting opportunity for a living history flight experience. Guests are allowed to take a ride and soar among the clouds in the B-52 “Made in the Shade,” and hear the rumble and roar of the engines, feel the wind in their face, and imagine themselves as part of the flight crew from over 70 years ago. The B-25’s most famous exploit was the April 18, 1942, Doolittle Raid on Japan.

Whether you visit the museum in Mesa, Arizona, or catch them on one of their many summer tours, people are able to schedule a flight on one of the warbirds and commemorate history.

“Cass Precision Machining was fantastic for us. They got us the parts we needed for the B-25 faster than we expected, and we were able to get our planes back up in the sky,” said Dick Clifford, Commemorative Air Force Airbase, Arizona. “Cass could not have been nicer to work with; they provided high-quality parts to make our deadline.”

Cass’s bushings for the Commemorative Air Force plane are much better than the original as they are heat-treated, centerless ground and fit better, and last longer.

“The bushings Cass made for our planes are far superior to the ones they replaced, and will help in allowing us to fly these historic planes for years to come,” said Clifford.

“It’s an honor for Cass to be able to volunteer our expertise to help restore and keep the B-25 bomber flying for the Commemorative Air Force,” said Jim Garvin, Cass President. “Cass started as a company the same year WWII ended, and we’ve always done everything we can to help support the armed forces. To be able to provide a part that lets the B-25 bomber continue to fly and to fly safer than ever before is a thrill for us.”

Cass was more than happy to volunteer their time and professional expertise with the replacement bushings that allow the famous B-25 bomber to remain flying.

We were also happy to see that the story of our contribution was picked up by newspapers and websites across the country, including Yahoo Finance, the Associated Press, and the Chicago Herald.
