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.

At Ktech we have experience machining many different types of plastics and achieving close tollerances. If you require cnc machined plastic parts please contact Ktech Manufacturing for a quotation.

The melting point and service temperature specifications are found at the Quadrant Engineering website.

We specialize in precision CNC machining (cnc milling and cnc turning) of small to medium sized components. We machine parts from a large range of materials including stainless steel, titanium, aluminum and many different types of engineering plastics such as PEEK, Ultem, Delrin and Nylatron. At Ktech, our mission is to be successful by effectively utilizing the philosophies of high quality, advanced techniques, and continuous improvement in order to provide superior products and customer service to clients requiring specialty machining services.

Maintaining tolerances is a top priority on all parts produced, but working together with our customers to determine the critical tolerances before production is key to end cost reduction and customer satisfaction. At Ktech we value the relationships we have with our customers and by working closely together we are able to ensure that parts are made to specifications, function as required and are priced competively.

Ktech Manufacturing is a Vancouver area cnc machine shop.

At Ktech we specialize in machining specialty materials such as PEEK (Polyetherketone), we machine a variety of different types of parts from the various grades of PEEK material such as different percentages of glass filled PEEK and Virgin PEEK. PEEK is a  thermoplastic with many desirable characteristics for the electronics industry and uses where resistance to high temperature degradation is important. Peek is on the more expensive materials when it comes to specialty plastics. PEEK melts at around 350°C (662°F) and is highly resistant to thermal degradation. The material is also resistant to both organic and aqueous environments. PEEK also exhibits good chemical resistance in many other environments, including alkalis (i.e. sodium, potassium and ammonium hydroxides), aromatic hydrocarbons, alcohols (i.e. ethanol, propanol), greases, oils and halogenated hydrocarbons.

Uses for Peek:
PEEK is used in bearings, piston parts, pumps, compressor plate valves, and cable insulation applications. It is one of the few plastics compatible with ultra-high vacuum applications. The large temperature range of PEEK makes it a very useful product in the electrical circuitry industry.

Properties of PEEK
Density 1300 kg/m3
Young’s modulus (E) 3700 MPa
Tensile strength (σt) 90 MPa
Melting Point ~350 °C
Heat transfer coefficient (λ) 0.25 W/m.K
Linear expansion coefficient (α) 1.7 10-5 /K
Machinability PEEK is easily machined using high speeds (RPM), high feeds, and lots of coolant.

NOTE:
We have helped customers save considerable amounts on CNC machined parts by switching materials from PEEK to a different thermoplastic that exhibits very similar characteristics but costs considerably less for raw material.
