Ultem is the best-known trade name for polyetherimide (PEI), a high-performance amorphous thermoplastic used when ordinary plastics do not provide enough heat resistance, stiffness, flame performance or dimensional stability. In its natural unfilled form, PEI is typically translucent amber. Glass-reinforced and specialty grades are also available for applications that need higher stiffness, lower thermal expansion,…
Quick answer: ABS (acrylonitrile butadiene styrene) is a tough, rigid, impact-resistant amorphous thermoplastic used for housings, fixtures, covers, brackets, prototypes, electronics, automotive parts, and many other manufactured components. Because ABS is a family of grades, exact heat, impact, flame, safety, and machining properties must be verified from the selected supplier grade. What Is ABS…
Grade 5 titanium cuts weight, while 316L stainless steel offers higher stiffness and usually lower machining costs. Compare corrosion, tooling, tolerances, and part fit.
This guide helps engineers choose between ferrous and non-ferrous metals by matching alloy grade to part performance and production needs.
PTFE is valued for low friction, chemical resistance, and insulation, but its softness makes precision machining difficult. This article explains how tooling, support, temperature control, and realistic tolerances help produce stable PTFE CNC parts.
Thermosets and thermoplastics differ mainly in how they respond to heat. This guide compares their structure, strength, recyclability, machinability, and best-use cases for medical, semiconductor, photonics, and robotics parts.
POM, also known as Delrin or Polyoxymethylene, is one of the most commonly used engineering plastics in modern manufacturing. This thermoplastic is widely applied in components and manufacturing products because it combines reliable processing capability with balanced material characteristics. Today, these materials can be found in automotive, electronics, medical, and equipment manufacturing. What Is…
