Can you injection mould PEEK?

Overview

PEEK is a high-performance thermoplastic with excellent mechanical properties, chemical stability and high temperature resistance. PEEK injection molding is a process used to produce PEEK parts that involves injecting molten PEEK resin into a mold, where it cools to form the desired shape.

Key Factors

Key factors affecting the success of PEEK injection molding include: mold design, processing parameters, material selection and post-processing. Optimizing these factors is critical to producing high-quality PEEK parts.

Applications

PEEK injection molding is widely used in various industries, including aerospace, automotive, medical and electronics. Its excellent properties make it ideal for manufacturing high-performance parts.

SOME USEFUL Q & A.

Can you injection mould PEEK? How is PEEK molded?

PEEK can be moulded on standard injection moulding machines supplied by most of the well-known machine suppliers.

What temperature is PEEK molded at?

Depending on the grade of PEEK that you'll be moulding, processing temperatures on your injection moulding barrel will be somewhere in the range of 350-400℃.

How much does injection molding PEEK cost?

It's depanding on the kinds of PEEK pellet, generally, the materials are Pure PEEK, PEEK CF30, PEEK GF30 and PEEK MOD. The cost is 50-80usd/kg acc. to different drawings.

What is the pressure for PEEK injection molding?

The ideal injection pressure for PEEK resins should be between 10152.6 – 20305.3 psi / 70-140 Mpa.

Which kind of PEEK pellet is suitable for injection molding?

PEEK granules with low and standard viscosity is good for injection molding.

Could I use recycled or re-used PEEK as raw material for injection moulding?

It's absolutely NO, you need to use whole new PEEK granules, or black spot and inner defects will be faced.
