A Waffle Iron and Running Shoes
I'm sure just about everyone is aware of the shoe company known as Nike® that calls Oregon its home, but do you know how the company got its start? If you know about the company's history then you know where I am going with this blog post and how I will tie it into metalcasting. Otherwise, continue reading to see how one man used household items to innovate the entire shoe industry.
Techniques for Controlling Hardness
In the industrial market place, a casting buyer will typically know exactly what he/she is looking for in their alloy choice. The buyer will specify which alloy (ex: aluminum T356) and which certifications it must pass (tensile strength, elongation etc.) based on what the casting will actually be used for. But what if you are unfamiliar with purchasing castings and aren't exactly sure what all the tests and numbers mean? You can ask your casting supplier who should help you, or if you are like me you can search the internet and try to figure it out yourself. If you are reading this, chances are you are like me and decided to search the internet to find the answer.
Some Changes at CPM
There have been some changes happening at CPM Industries that have required me to switch my priorities from blogging to other areas. I know I have been slacking on the blog posts lately and I apologize for that, but I will be getting back into it in the near future. We have been busy lately and in order to accommodate, we made some extra room in the shop to help alleviate "traffic."
Making Changes to a Pattern
At CPM Industries, we produce Patterns and Tooling used for a couple different casting technologies, but the majority of our patterns are produced for sand casting. Here at CPM, we prefer to use a polyurethane based board to produce our patterns for a couple of reasons. There are several different types of polyurethane boards that we use and they all differ from each other on their hardness. For production castings we use the red polyurethane board, or red-board as we call it. The red-board provides the durability needed for the constant and repeated use that it must endure for producing high quantities of castings. For prototype castings we use (what we call) brown-board because it is not as hard as the red-board which makes it easier to make minor changes to. Another reason we use the brown-board is that it is cheaper, making it more cost effective for our customers; why pay for production tooling when all you need are a handful of prototypes?
Castings Used to Explore the Ocean
While scrolling through the infinite collection of "stuff" that is the internet, something caught my attention that I thought was completely unrelated to work. What caught my attention was a full body suit that looked like it belonged on the space shuttle to be used on the moon (pictured right). As I read through the article I was a little surprised to read that the suit was actually designed and built for deep sea exploration and/or recovery. I was really surprised to read that the entire suit is built from machined 6061T Aluminum Castings... talk about close tolerance machining!
Reinspect Your Castings
Recently we encountered a problem with one of our castings that appeared to be a result of misread of the machine print or an error during machining. On an aluminum casting there were several holes that needed to be drilled and tapped, but one specific hole presented a problem on a number of castings. After machining we performed our standard inspection and the casting passed as expected, so we shipped the castings off to get impregnated.
Using Gravity to your Advantage while Casting
Castings can have very complex designs with thin walls, ribs, and/or fins that can pose major problems for the foundries. Common problems that can occur while casting thin walls or ribs is porosity issues and inclusions. Porosity issues and inclusions are common problems that can happen with any casting, but while casting thin walls or ribs these issues can be catastrophic.
Medical Implants are on the Rise
As you can obviously see, the update to the software that we use to publish our blog posts is up and running. The updated software allows for all kinds of new design features and publishing options to help us further improve out blogging. As always, if you have any questions about anything related to the metalcasting process and/or industry, machining, pattern making, etc. submit them to us and we will answer them directly, or may even use it as a blog topic. The best way to submit a question is via Facebook.

My Trip to IMTS 2014
The International Manufacturing and Technology Show (IMTS) is exactly what the title implies, anything and everything to do with manufacturing can be found at this show. The show is held at Chicago's McCormick place, which is the perfect venue due to its massive size. For those that are unfamiliar with the McCormick Place, it is one massive building that is actually made up of several interconnected buildings that can be used for a variety of things (it is home to the Chicago Auto Show).
2014 IMTS is Almost Here!
The 2014 International Manufacturing Technology Show is rapidly approaching, are you ready? The IMTS is one of the worlds largest industrial trade shows featuring over 1,900 exhibitors, drawing in over 100,000 visitors to Chicago's McCormick Place. With the amount of visitors this event draws, no wonder so many manufacturers make the trek to Chicago to show off their stuff.

Congratulations to Jackie Robinson West All Stars
As many of you probably already know, a Little League team from Chicago's South Side has been in the spotlight recently due to their success at the Little League World Series. The team from the south side has been featured much more in the local news and has drawn support from the entire city of Chicago. The team from Jackie Robinson West has also helped bring a community together that has been in the spot light in recent months due to the amount of violence and crime throughout the area. It is amazing what one common goal can do to bring a community together, even while battling ever increasing crime.
Little League world series,

New Costly O-zone Regulations
The Environmental Protection Agency (EPA) is once again faced with a major dilemma; lower the National Ambient Air Quality Standards (NAAQS) or leave them as is. Lowering the standards is intended to slow global warming and help preserve this planet for generations to come, while on the other hand the lowered standards would come with a hefty price tag to the manufacturing industry.

Competitive Advantage in Sand Casting
By definition, competitive advantage means "a condition or circumstance that puts a company in a favorable or superior business position." After 3 generations of ownership and 50+ years in business, we believe we have developed a distinct competitive advantage over many of our competitors. Our competitors can be grouped into four groups because our competitive advantage allows us to compete in several markets. Our competitors are either a foundry, pattern shop, machine shop, or any combination of the three.

Metal Casting Blog Topics
The majority of our blog topics come from common questions that we get asked from day to day. Other topics come from industry magazines that we subscribe to, trending topics on the internet, or anything that I find interesting enough to share with you. But now you get the opportunity so submit questions to us that you may have about metal casting/sand casting, machining, pattern making, or the industry in general. (aka I need your help for blog topics related to metal casting)
