About the materials

The graph above shows the relationship between heat resistance and tensile strength.

PEEK

It is an abbreviation for Poly Ether Ether Ketone, a type of thermoplastic resin known as super engineering plastics.This material offers excellent heat and hydrolysis resistance, along with outstanding mechanical sliding properties.

Its excellent chemical resistance and certified food safety, this material is also suitable for use in medical settings.

PPS

Like PEEK, it is a type of thermoplastic resin called super engineering plastic. PPS is an abbreviation for "polyphenylene sulfide"..Combining exceptional heat resistance, chemical durability, rigidity, and insulation performance, this material is increasingly recognized as a lightweight alternative to metal components in electric vehicles.Due to its vulnerability to impact and surface wear, caution is required during use and handling.

TNK handles materials that combine the above with CF (carbon) and GF (glass).

Beyond the examples provided, we offer material recommendations based on your requirements, including thermal performance, mechanical strength, and budget. Please don’t hesitate to reach out.

Application examples of use for sliding screws

TNK produces plastic nuts as a combination product with TNK screws.

By applying our shaft manufacturing know-how, TNK produces screws and resin nuts internally, enabling flexible clearance settings tailored to each application. For SUS303 stainless steel screws, we have achieved an ultra-precise clearance of just 2 μm when paired with CF-reinforced PPS resin nuts demonstrating our advanced processing capabilities.

Durability：Operating distance: 500km or more,Load capacity up to 20,000N

Composite materials handled

CFRP (carbon fiber reinforced plastic)

CFRP is both lightweight and exceptionally strong, making it a material of growing interest across a wide range of industries including aerospace, automotive, and industrial machinery. TNK is also challenging itself with processing composite materials. Please feel free to contact us.

Taking on the challenge of near net shape

TNK also adjusts for additional processing from near net shape to reduce product costs.

In addition to machining from solid materials, we minimize material waste through techniques such as lost wax casting, 3D printing, and post-processing after friction welding of dissimilar materials. These approaches help reduce the cost of expensive materials like titanium. If you're facing challenges such as rising part costs due to material price increases, or if you need support with VA/VE initiatives, please don’t hesitate to contact us.
