Stainless Steel Pin Plate for Polyimide Film Stenters

This pin plate is made for polyimide film stenters, not for fabric. The plate is high-strength stainless steel, heat resistant up to 800 degrees and corrosion resistant, because a PI film line runs far hotter than a textile heat setting range. Polyimide film is used in electronics and aerospace for insulation, heat insulation and protection, and the film has to be held under tension without the plate itself distorting.

  • Materialstainless steel
  • Coloursilver
  • BrandYH
  • OriginZhejiang, China

Key Benefits

  • High-strength stainless steel rated to 800 degrees, well above textile chamber temperatures
  • Corrosion resistant, so the plate survives the chemistry around a PI film line
  • Holds film tension so the line speed can be raised
  • Made to the film stenter hole pattern, not adapted from a fabric plate

Application Scenarios

  • Polyimide film casting and tenter lines
  • High-temperature film heat setting
  • Electronics and aerospace film production where film flatness is critical

Who It Is For

  • Polyimide film producers running tenter frames
  • Engineering teams specifying wear parts for high-temperature film lines
  • Maintenance teams replacing plates that have distorted at temperature

Problems It Solves

  • Copper-bodied fabric pin plates softening and distorting at film stenter temperatures.
  • Film slipping off the pins as the line speed is raised.
  • Plates corroding in the chemistry around the film line.

  • Plates matched to your film stenter hole pattern from a sample
  • Pin height and pin pitch set for your film thickness
  • Matched sets for a full rail

How It Compares

Compared WithWhat Changes
Copper fabric pin platesCopper conducts heat well for textile chambers but is not the right choice at 800 degrees. This plate is stainless steel throughout.
Standard stainless pins on a copper plateHere both the plate and the pins are stainless, so nothing in the assembly softens at film line temperature.
Use Guide

Fitting and Replacing This Part

  1. Step 1

    Stop the machine and let the assembly cool before stripping it

  2. Step 2

    Note how the old part sits before removing it

  3. Step 3

    Clean the seat completely before fitting the new part

  4. Step 4

    Turn the rail by hand for one full pass and check free movement

  5. Step 5

    Replace in complete sets so grip and wear stay even across the machine

Questions

Stainless Steel Pin Plate for Polyimide Film Stenters Questions

What temperature can this plate take?

The stainless steel plate is heat resistant up to 800 degrees, which is why it suits polyimide film lines rather than textile heat setting.

Can I use this plate on a fabric stenter?

You can, but it is more plate than a fabric line needs. For textiles the copper plate with steel pins conducts chamber heat better and costs less.

Why does PI film need a different plate?

Polyimide film is processed far hotter than fabric, and the film has to stay flat. A plate that softens or distorts at temperature will pull the film out of shape.

Do you make the film stenter holder as well?

Ask us with a photo. We quote holders and related chain parts against a sample or a drawing.
