CNC Machining Plastic Material of Choice

Certainly, specific Plastics maintain their own unique benefits. A quick guide for example, the following are some of the most used Plastics in CNC Machining Plastic guide operations:
  • Ultra-high molecular Polyethylene (UHMW), due to its high machinability
  • Nylon, due to its affordability, strength, durability, and corrosion and chemical resistance
  • Acrylic, due to its formability, high tensile strength, and resistance to cracking and abrasion
  • Polyether ether ketone (PEEK), due to its chemical and wear resistance and ability to withstand high temperatures.
The success of any machining project depends on selecting a material and machining process that complement each other. Careful planning ensures both performance and cost‑effectiveness. At Sentinel Plastics Ltd, our team can assist you in evaluating the key factors involved — from material properties and machining behaviour to tolerance requirements and intended application.
