PEEK molding / PEEK injection


A perfect PEEK molding & PEEK injection 

(PEEK bushing / PEEK gear), we assures its 

customers to provide a perfect molds for 

the perfect PEEK material parts which 

include PEEK bushing, PEEK gear, PEEK ring, etc.




Application:  for Automotive, Aerospace, Defense and Oil & Gas industry

MING-LI provides our customers with competitive molding solutions in high performance plastics. We offer unique expertise in the injection molding of PEEKTM, PPA, PPS and other high performance resins.

We have invested significant resources to develop industry leading expertise in PEEK molding and other advanced material applications.

With our world class in-house engineering, design, tooling and processing capabilities, MING-LI can work with you from the design concept stage to high volume production. By incorporating tooling and manufacturing improvements throughout the development cycle, MING-LI can help you optimize your component for production, bringing real value to your organization.

Ming-Li offers injection molding of all Victrex PEEK, RTP PEEK, Luvocom PEEK and others all PEEK grades.Our in-house molding operation uses all electric machines with appropriately sized barrels minimizing time at temperature during molding to maximize the properties and consistency of every part we mold. Our range of machine sizes between 15 to 300 tons means we can mold parts ranging in size from 0.1 g. to 600 g.

We design our process to meet your needs. Our injection-compression molding machines combined with our experience processing PEEK enables us to do what others cannot: precision tolerances, zero draft, fiber orientation, insert molding and heavy cross sections. All machines are RJG equipped allowing us to monitor in-cavity conditions and develop the most reliable molding process for a given part. We apply scientific molding principles when molding PEEK parts.

We are recognized as a leading molder of high temperature PEEK and PEK based polymers.

The Ming-Li Difference

l   All runs start with a clean barrel and end with a complete teardown

l   Dedicated membrane dryers and moisture recorded before every run is started

l   All tools are oil heated for uniformity

l   PEEK Near Net Shapes offer a balance between the cost effective conversion of injection molding and the precision of CNC machining.

Near Net Shapes – What are their benefits?

Near net shapes are great for geometries that result in a poor machining yield from a stock shape or those requiring complex tools that are not cost justified by the volume of parts.


We use following PEEK material from Victrex:
