Applying Polyfuze Graphics™ to PP and PE components is similar to hot stamping and heat transfer decorating. The combination of pressure, temperature and dwell is required to transfer an image from a carrier to a part. These three components are interdependent and a change in any one of them, may affect success or failure in the application process. Please contact us at (928) 634-8888 for any questions or issues.

A few notes before you start stamping:
- Make sure the face of your silicone rubber die is at least 450-460°F and clean from all debris.
- Make sure your tooling is lined up with the application die and everything is
- Make sure the Polyfuze Graphics™ are tracking straight through the press.
- The stripper rollers should have the film approximately 1/2” below the die face.
- Make sure the right air pressure is set for the size of graphic that you are stamping.
- Set dwell time and make sure the HEAD-UP delay is on.
- Check all safety devices on the press.
Remember: When molding a plastic part, the molding press must lock up solid to make a good part. The same is required when decorating that part, it must be fully supported and solid.
Determining What is a Good Application:
To determine if the graphics have been applied properly there are a few tests that
can be done after the part cools.
- Visual Inspection. Was all of the graphic applied and is it straight with no wavy
lines? Do you see an impression from the die showing the melt line around the
graphic? This is our Quality Control mark. When you see this mark you know that
the graphic is fused into the part.
- Touch Test. Run your finger across the graphic. Does it feel like it is on top of the
plastic? Polyfuze Graphics™ are designed to fuse into the plastic. The surface
should feel smooth depending on the base material.
- Scratch Test. If the graphic scratches o easily with a fingernail, it isn’t fused.
However, if you dig at it to remove it, and damage the part in doing so, it’s fused.
- ASTM D3359-09 Crosshatch Tape Test. Score the graphic with a knife into
1/8” squares. Apply Scotch 893 tape over the crosshatch pressing firmly. Peel the
tape o perpendicular to the graphic and inspect for any graphic on the tape.
