Common Plastic Materials for Injection Molding

There are hundreds of plastic materials for injection molding. Different plastic resins impart different end-use properties, such as tensile strength and impact resistance. Injection molded plastics also have specific processing requirements, such as melt temperature and molding pressure. There are also different grades of the same plastic material, including resin types with fillers such as […]

Working with Copper: Design, Machining, and Finish Requirements

Copper is a truly versatile metal. Copper has a naturally beautiful, shiny finish that makes it desirable for artwork, cookware, kitchen backsplashes, countertops, and even jewelry. It also has excellent material and electrical properties for engineered, complex parts, like EDM electrodes. There are many benefits to using copper for machined parts. Copper is one of […]

Finding the Right Secondary Operations after CNC machining, Part I: Heat Treatments

Once you’ve finished CNC machining your parts, your work isn’t done. Those raw components might have ugly finishes, may not be strong enough, or be just one part of an assembly that’s got to be connected with others to make a complete product. After all, how often do you use devices composed of a single […]

What You Need to Know About CNC Machining Aluminum

Aluminum is the name of the most abundant metallic element found in earth’s crust, which is part of the reason why it’s used in so many objects that we use every day. In fact, it’s the most widely used non-ferrous metal (meaning that it doesn’t contain any iron). Aluminum is found both in common objects, […]

ABS Injection Molding: Material Properties and Processing Considerations

ABS is a commonly used plastic injection molding material with three main ingredients: acrylonitrile, butadiene, and styrene. Each of these monomers imparts specific properties and provides ABS terpolymer with a robust combination of features. The “A” in ABS, acrylonitrile, imparts hardness and heat and chemical resistance. The “B”, which stands for butadiene, provides toughness and […]

The Many Types of Steel, and What You Should Know About CNC Machining Them

Steel comes in many forms: sheet metal, plates, bars and beams of various geometries, pipes, and of course, the solid stock material used when CNC machining steel. Steel is used for so many applications and by so many industries that it makes sense for there to be many different types of steel. But what’s the […]
