High-end card manufacturing leaves little room for surface defects. A single scratch, dent or striation on a laminating plate can be magnified during lamination, raising reject rates and compromising the finish of smart cards and bank cards. The choice of plate material, surface finish and thermal consistency has therefore become a critical quality-control decision.
Precision laminating plates as a quality control point
In plastic card production, the surface quality of the laminating plate directly shapes the final product’s appearance and durability. Minor imperfections can be amplified during lamination, increasing waste and making surface uniformity a central production concern.
Available plate options include classic stainless steel, aluminum and high-hardness specialty alloys. The plates are custom-finished and precision-polished in Viersen, Germany, to promote consistent heat conduction and heat distribution during lamination of PVC, PC, ABS and PET(G) materials.
Hardened plates for high-intensity production
For smart cards and bank cards, where surface wear resistance is especially important, hardened plates are specified. Special treatment improves resistance to scratches and damage, extending service life and helping maintain consistent output over long, high-frequency production runs.
Beyond standardized polished surfaces, plates can be customized for specific process requirements, including surface hardness, dimensions and special treatments. Each plate is inspected for flatness before shipment and packed under ISPM No. 15 standards with protective film on both sides to preserve condition in transit.

Frequently Asked Questions
What is the difference between FT G1 and FT G2 when selecting a plate?
The main difference lies in surface hardness and brightness. FT G1 requires a surface hardness of >= 850 HV and is suited to applications with very high wear-resistance requirements. FT G2 requires >= 400 HV and has a brightness value of >= 600°, offering better surface gloss while maintaining a certain strength. Selection depends on the specific surface requirements of the card product.
How is consistent heat conduction ensured during lamination?
The plates use high-quality stainless steel and precision polishing to ensure consistent thickness of 0.8 mm and surface roughness of RA < 0.03 µm. This consistency is key to even heat distribution during lamination, helping to avoid card surface defects caused by localized temperature differences.
What should be considered when specifying custom plates?
Because each plate is custom-made in Germany to a customer’s specific process requirements, the product is not held as stock inventory. Material specifications, surface treatment requirements and dimensional tolerances should be defined early in project planning so production timing can be assessed and the most suitable solution matched.
