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 […]

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 […]

Overmolding Materials Guide: Material Bond Compatibility

Overmolding is widely used to combine materials with different properties—such as rigid substrates and soft-touch elastomers—into a single component. Common examples include tool grips, seals, and consumer products like toothbrushes. However, successful overmolding depends heavily on material compatibility. Poor adhesion between materials can lead to delamination and part failure, making proper material selection and interface […]

Material Selection for Medical Device Manufacturing: The Best Medical Grade and Biocompatible Options

Medical device materials must meet strict requirements for biocompatibility, sterilization compatibility, traceability, and regulatory documentation. Engineers selecting materials for medical device development must balance mechanical performance, manufacturability, cost, and regulatory compliance across the entire development lifecycle—from early prototypes to full-scale production.  Medical devices range from simple disposables to complex multi-material systems. This guide explains common […]
