Temperature beyond textile specification
A standard textile pin plate is not made for these conditions. The plates we supply for PI film are high strength stainless steel, heat resistant up to 800 degrees and corrosion resistant.

Polyimide film is a polymer film with high temperature resistance and chemical stability, commonly used in electronics, aerospace and other high technology applications for insulation, heat insulation and protection. The stenter lines that produce it run far hotter than any textile frame, and a textile pin plate will not survive there.
A standard textile pin plate is not made for these conditions. The plates we supply for PI film are high strength stainless steel, heat resistant up to 800 degrees and corrosion resistant.
PI film production combines high temperature with a chemically demanding environment, so corrosion resistance is not optional in the material choice.
Pinning increases the tension on the polyimide film, and higher tension is what lets the line run faster. A tired pin bed limits throughput directly.
Film is unforgiving of stepped pin height. Renewing by section keeps the pin line straight along the whole film path.

View DetailsWe customise parts according to customer needs: pin plates, pin plate holders, clips, brush wheels and other metal parts.
Parts for multiple brands of stenter machine, so a mixed fleet is served from one order.
They are made from high strength stainless steel and are heat resistant up to 800 degrees, which is what polyimide film production requires.
The material will not survive the temperature and chemistry of a PI film line. The geometry may look similar but the specification is not.
Yes. Pinning increases the tension on the polyimide film, which lets the line run faster.
Yes. Send a sample plate or a drawing of the holder seat.
Yes. We check the certificate on incoming stock and can pass it through with the order.
Electronics, aerospace and other high technology applications, for insulation, heat insulation and protection.
The stenter heat-sets and dries fabric by stretching it to width and holding it there under controlled heat.
Entry section, clip or pin chains, rails, heating chambers, exhaust, blowers, temperature control, width adjustment and weft straightener.
Clips leave no pin marks and suit thicker fabrics; pins hold more tension and run faster, to 100 m per minute.
