Injection plastic cards

When sourcing injection plastic cards, the primary material is usually PVC, ABS, or PETG. For high-durability requirements, polycarbonate (PC) is preferred due to its heat resistance. Ensure the supplier uses 100% virgin resin rather than recycled materials to prevent brittleness and yellowing. The standard thickness for CR80 cards is 0.76mm (30 mil), but injection molding allows for custom 3D shapes, embossed logos, and variable thickness that standard laminated cards cannot achieve.

For standard dimensions, cards should comply with ISO/IEC 7810 ID-1. If the cards include electronics, verify ISO/IEC 14443 for RFID or ISO/IEC 7816 for contact chips. For the US market, UL 94 V-0 flammability ratings may be required for industrial use, while the EU market necessitates RoHS and REACH compliance to ensure the absence of hazardous substances like lead or phthalates.

Injection plastic cards offer superior structural integrity because they are molded as a single solid piece rather than layers glued together. This process is ideal for heavy-duty access tags, waterproof key fobs, and cards with integrated components like LED lights or sensors. It allows for precise internal cavities to protect delicate chips from mechanical stress and environmental factors.

Buyers should demand a tolerance level of ±0.02mm for dimensions. Key tests include the torsion test (bending the card 30 times without cracking) and surface tension testing to ensure printing inks or coatings adhere properly. For cards with embedded chips, a 100% functional electronic test using automated readers is essential before shipping to avoid a high Defect Arrival Rate (DAR).

When sourcing cards with pre-programmed chips, ensure the supplier signs a Non-Disclosure Agreement (NDA). Use encrypted data transmission for UID lists or encoding files. It is highly recommended to source from Audited Suppliers on Made-in-China.com who have undergone third-party verification of their security protocols and manufacturing facilities.

Injection molding involves high initial tooling/mold costs (CAPEX). Negotiate for a mold fee refund once your cumulative order volume reaches a certain threshold (e.g., 50,000 units). For recurring orders, request price stability agreements for 6-12 months to hedge against fluctuations in global plastic resin prices.

Plastic cards are heavy and sensitive to extreme heat, which can cause warping. Specify vacuum-sealed inner packaging to prevent moisture ingress and double-walled corrugated export cartons. For sea freight, ensure the pallets are shrink-wrapped and strapped to prevent shifting. Always clarify Incoterms (typically FOB or DAP) to define exactly where the risk transfers from the seller to the buyer.

Always utilize Secured Payment services provided by reputable B2B platforms like Made-in-China.com to ensure your funds are only released after you confirm receipt of goods. Additionally, consider hiring a third-party inspection agency (like SGS or Intertek) to perform a Pre-Shipment Inspection (PSI) to verify quantity and quality before the final balance is paid.
