Machining Engineered Platics:
At Ktech one of our specialties is cnc machining plastics for applications such as electronics, oil and gas, food and beverage, and medical research. There are virtually numerous types and grades of engineering plastics available, below is a brief list of some of the types of plastics we frequently cnc machine plastic parts from. You will find information such as machinability, melting point, maximum service temperature in air, and a material cost reference.
Machinability scale: 1-10 (1 being easiest to machine)
Cost scale: 1-10 (1 being the lowest relative cost)
Delrin / Acetron
- Melting Point: 168 °C or 335 °F
- Maximum Service Temperature, Air 82.2 °C or 180 °F
