What the AI looks for in Plastic Shims & Shim Stock
- Color coding by thickness
- Prefer assortments where each thickness has its own color Thin plastic shims are impossible to tell apart by eye or feel.
- Material
- Polyester (PET) shim stock for dimensional stability; avoid soft plastics under clamp loads Soft polymers cold-flow under load and the gap reopens.
- Thickness tolerance
- Verify the stated thickness with a micrometer when the shim sets a critical gap Plastic gauges can vary within a sheet.
- Temperature and load
- Use metal shims for hot or heavily loaded joints Plastic shims soften with heat and creep under sustained high load.
Brands that matter
- Precision Brand: Long-standing shim-stock maker in metal and plastic.
- Artus: Shim specialist with precut and slotted styles.
What to avoid
- Unlabeled mixed packs with no thickness markings or color code
