Into Puju Technology - Precision Manufacturing

PEEK, PI, PAI, PEI, PPSU, LCP, PPS and other ultra-high precision injection molding / ultra-high precision gear injection molding


Founded in 2007, Shanghai Puju Plastic Technology Co., Ltd. Is a high-tech enterprise that can provide precision injection molding of special plastics such as polyetheretherketone (PEEK). Taking new materials, high performance and ultra-precision as the brand strategy, we will achieve "high, refined and new". It breaks through the difficult problem of PEEK injection molding; it gives the product higher performance through material modification. It has R&D department, precision injection molding department, and German import PEEK board, rod and tube department (authorized by German companies).

The PEEK precision injection products produced by the company have replaced a large number of precision components that depend on imports, and are used in steering, brakes and other parts of automobiles. The PEEK precision injection gears produced by the company have largely replaced imported precision gears and are widely used in various industries. The PEEK precision injection products produced by the company are also used in equipment, aerospace, automotive, energy, chemical, electronics, machinery and other industries.

The quality testing equipment includes: German Zeiss three-coordinate, imported high-precision gear measuring center, imported gear meshing instrument, Japanese Keyence optical measuring instrument, Japanese Nikon tool microscope, etc. The company has passed the IATF: 16949 quality system. After nearly 20 years of experience accumulation, we can provide customers in various industries with a complete set of solutions for material selection, proofing, and mass production. It can be produced by injection molding according to the drawings, and there is no MOQ.

All kinds of general mechanical PEEK injection molding products produced by the company have also been well received by users, such as:

PEEK injection gear, PEEK blade, PEEK sealing strip, PEEK sealing ring, PEEK sealing plate, PEEK valve plate, PEEK aviation bracket, PEEK star wheel, PEEK low temperature sealing ring, PEEK high temperature sealing ring, PEEK low temperature sealing gasket, PEEK high temperature sealing Pads, PEEK bearing cages, PEEK impellers, PEEK wear strips, PEEK wear plates, PEEK medical joints, PEEK fracturing balls, PEEK gaskets, PEEK valve seats, PEEK bolts, PEEK oil-free bushings, etc.
