Advanced Materials Guide for Injection Molding

The advent of CAD systems, additive manufacturing, and CNC machining have made the design and manufacture of complex part designs almost routine. Engineers today are tasked with designing components that may be subjected to a variety of factors, including extreme weather conditions, chemicals, bodily fluids, high stress or loads, impacts, and other elements that could […]

Thermoplastics vs. Thermoset Plastics: Material Properties Overview

Thermoplastics and thermoset plastics are classes of polymers used in injection molding, CNC machining, 3D printing, and urethane casting. Like elastomers, another class of polymer, thermoplastics and thermosets both consist of long, repeating chains of molecules. Under a microscope, the structure of a thermoplastic resembles a railroad track while a thermoset material looks like a […]

Sheet Metal Material Selection for Aerospace Applications

Choosing sheet metal for manufacture in aerospace isn’t just a matter of selecting the strongest or lightest alloy. For instance, a stronger material that suits machined components may crack during bending, while one that forms easily may lack the fatigue strength for vibration-loaded structures. An apparently suitable alloy may fail in salt spray, elevated temperatures, […]

Material Traceability in Manufacturing: A Guide for Engineers and Procurement Teams

When a manufacturing customer requests a material certificate, they’re really asking multiple questions at once: was this material tested, did it meet the standard, and is this the actual material used to make my part? These questions need a clear, documented answer. In practice, the gap between them is where things go wrong. Material traceability—the […]

Aerospace Materials and Finishes: Component Design for Spacecraft and Satellites

Engineering for Vacuum, Thermal Extremes, and Reliability Aerospace materials and finishes for spacecraft must be selected to withstand vacuum, radiation, thermal cycling, and outgassing. These conditions introduce failure modes such as cold welding, material degradation, and contamination of sensitive components, requiring material and surface finish selection to be evaluated together to ensure reliable performance in […]

High-Strength CNC Machining Materials: Selection, Trade-offs, and Design Considerations

Material strength is a primary design factor directly linked to product performance. High-strength materials allow for smaller parts, thinner walls, higher load-bearing capacity, and greater resistance to deformation. More strongly bonded materials also withstand extreme operating conditions better without deformation or failure.   Material selection for CNC machining, though, is rarely as simple as selecting the […]
