Stainless Steel Pin Plate For Polyimide Film Lines
High strength stainless pin plate rated to 800 degrees for PI film stenter lines.
Product Overview
Polyimide film is a polymer film with high temperature resistance and chemical stability, 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 a textile frame.
This pin plate is made from high strength stainless steel, heat resistant up to 800 degrees and corrosion resistant, fully adapted to PI film production. It works the same way a textile pin plate does: the plate sits on the holder, the holder is on the chain, and the press wheel presses the film onto the pins so it travels forward with the chain. Pinning increases the tension on the film, so the line runs faster.
Key Benefits
- High strength stainless steel rated for temperatures up to 800 degrees
- Corrosion resistant, fully adapted to polyimide film production
- Increases film tension so the line speed goes up
- Made by a factory that also produces the textile pin plates, so the same process control applies
Who It Is For
- PI film producers supplying the electronics and aerospace sectors
- Engineers specifying pin beds for high temperature film lines
- Buyers who cannot use a standard textile pin plate because of line temperature
Problems It Solves
- Standard pin plates degrading at PI film line temperatures
- Corrosion in a chemically aggressive high temperature environment
- Film tension too low to run the line at its designed speed
Application Scenarios
- Polyimide film production lines for electronics insulation
- High temperature film stenters where standard textile plates will not survive
- Aerospace and electronics film manufacturing requiring thermal and chemical stability
Technical Features
- High strength stainless steel construction
- Heat resistant up to 800 degrees
- Corrosion resistant
- Works with the pin plate holder and chain in the standard arrangement

Quality Control
- Material certificate checked on incoming stainless stock
- Pin height and straightness measured on every plate
- Seat flatness verified so the plate does not rock under the press wheel
Customisation Options

Certifications. We make no certification claim for this part. The original company statement is that products comply with international quality standards; no certificate is named and none is asserted here. Ask us directly if your procurement process requires documentation.
Comparison With Other Options
Against a textile pin plate, this trades cost for temperature and corrosion capability. On a textile frame the standard plate is the right choice. On a PI film line a standard plate is the wrong material and will not last.
Use Guide
Confirm your maximum line temperature with us before ordering
Fit whole sections so pin height stays continuous along the film path
Set the press wheel to seat the film fully without marking beyond the edge
Inspect for pin distortion at each planned stop, because film lines run hot continuously
Keep the material certificate with your machine records
FAQ
Questions About Stainless Steel Pin Plate For Polyimide Film Lines
What temperature can these plates take?
They are made from high strength stainless steel and are heat resistant up to 800 degrees, which is what PI film production requires.
Why not use a standard textile pin plate?
Because the material will not survive the temperature and chemistry of a PI film line. The plate geometry may look similar but the specification is not.
Does pinning help on film as it does on fabric?
Yes. Pinning increases the tension on the polyimide film, which lets the line run faster.
Can you match our existing holder?
Yes. Send a sample plate or a drawing of the holder seat.
Do you supply material certificates?
Yes, we check the certificate on incoming stock and can pass it through with the order.
Lead time?
Quoted at order, because these are specified to the line rather than held as a running stock item.

Guides That Cover This Part
What Is a Stenter Machine and How Does It Work
The stenter heat-sets and dries fabric by stretching it to width and holding it there under controlled heat.
Key Parts of a Stenter Machine
Entry section, clip or pin chains, rails, heating chambers, exhaust, blowers, temperature control, width adjustment and weft straightener.
Pin Stenter or Clip Stenter Which To Use
Clips leave no pin marks and suit thicker fabrics; pins hold more tension and run faster, to 100 m per minute.
Send A Sample And We Will Match The Profile
Seat profiles and geometry changed across frame generations, so the part itself is more reliable than a model number. We identify it and quote the matching specification.
