Technical Guide Explains Hardened Steel Plate Selection for Plastic Card Lamination

Hardened steel plates are a critical precision component in plastic card manufacturing, shaping the surface appearance and tactile finish of cards made from PVC, PETG, polycarbonate and ABS. During lamination, the plates transfer controlled pressure and heat to the card layers, producing effects that range from high gloss and matte to silk-like and custom textures.

In card lamination, prepared material layers are stacked and pressed in a laminator under controlled temperature and pressure. The hardened steel plate serves as the contact surface, transferring its microscopic surface structure onto the outer card layer. Plate material properties, hardness and surface treatment are key factors in ensuring lamination quality.

By changing the specification of the lamination plate, manufacturers can achieve a range of surface effects:

• Matte and semi-matte
• High gloss
• Silk
• Custom textures and patterns

When sourcing or specifying plates, buyers should verify core technical parameters against equipment specifications and product design requirements.

The supply chain serving the Russian plastic card manufacturing market is diversified, covering international producers, local distributors and downstream application companies. Relevant companies include WALLIS, Verilion/Cardel, Komplekt Liga, US PLAST, KARD-PROM, 4Plate, Schwan-Laminations, RSID Solutions, NCS/NPO Neoprint, AKard, Poligraf Zashchita, Orenkart, Card Technology, Ostcard and San-Santu.

To ensure that purchased plates meet production requirements, companies should provide detailed technical specifications when issuing a request for quotation.

• Equipment parameters: Specify the laminator model and specifications.
• Dimensions and thickness: Provide precise physical dimensions for the plate.
• Surface requirements: State the required gloss level or texture type.
• Material matching: Identify the card substrate, such as PETG or PVC, to ensure compatibility with physical indicators including thermal expansion coefficients.
