Earring pendant mould

The most critical material is High-Tensile Food-Grade Silicone. Ensure the mould has a high transparency level (for UV resin curing) and a shore hardness of 20-30A to balance flexibility with structural integrity. The interior surface must have a mirror-finish polish to ensure the resulting resin pendants are glossy and do not require additional sanding.

Request technical data sheets confirming a temperature resistance range of -40°C to +230°C. This ensures compatibility with both epoxy resin (exothermic reaction) and low-melt wax or UV resins. For bulk orders, prioritize moulds that can withstand at least 50-100 de-moulding cycles without tearing or losing surface detail.

Even though they are craft tools, moulds often require LFGB (Europe) or FDA (USA) certification if they are marketed as multi-purpose (e.g., for chocolate or fondant). Additionally, ensure the silicone is BPA-free and Phthalate-free to comply with general consumer safety regulations like REACH.

Yes, professional suppliers on Made-in-China.com typically offer OEM/ODM services. You should provide 3D STP/STEP files or CAD drawings. The typical lead time for a custom CNC aluminum master mould is 7-10 days, followed by mass production of the silicone inserts.

This is a common issue with 'cheap' silicone fillers. Request a pre-production sample and perform a 'twist test'—if the silicone turns white when twisted, it contains fillers. Insist on 100% pure platinum-cured silicone in the contract to ensure long-term shelf life and prevent the moulds from becoming oily over time.

Since earring moulds are lightweight, Air Freight or Express (DHL/FedEx) is ideal for small batches. However, for large volumes, silicone is bulky. Use Sea Freight (LCL) but ensure the supplier uses vacuum packaging to reduce volume and sturdy outer cartons (5-layer corrugated) to prevent the moulds from being deformed under pressure during transit.

Focus on the weight of the silicone per unit rather than just the design. Ask for a tiered pricing structure (e.g., 500, 2000, 5000 units). You can often achieve a 15-25% price reduction by committing to a yearly volume while requesting staggered shipments to manage your inventory costs.

Always use Secured Trading Services provided by Made-in-China.com to ensure your payment is held in escrow until shipping documents are verified. Avoid direct wire transfers to private accounts; ensure the beneficiary name matches the company name on the business license.
