General Plastic Mold Injection Mold

1. widely used industry Injection molds are widely used in automobiles, home appliances, electronics, packaging, medical equipment, consumer goods, toys, office supplies, new energy and other manufacturing industries. They are mainly used in the production of plastic shells, structural parts, connectors, internal components, appearance parts and precision functional parts. 2. manufacturing process -Core process: design → material selection → CNC machining → electric spark (EDM)→ wire cutting (WEDM)→ grinding → polishing → heat treatment → assembly → mold trial → debugging → acceptance and delivery -Key processes: high-speed CNC machining, mirror EDM, precision grinding, deep hole drilling, cooling system processing, surface texture processing, coating treatment. 3. precision control -General accuracy: ± 0.02mm -Precision injection mold: ± 0.01mm -High precision mould: ± 0.005mm -Product dimensional tolerance: usually controlled within ± 0.05mm -Surface roughness: Ra≤ 0.8 μm (mirror polishing can reach Ra≤ 0.2 μm) 4. core equipment -Processing equipment: CNC machining center, high-speed milling machine, EDM machine, wire cutting machine, surface grinding machine, deep hole drilling machine -Molding equipment: injection molding machine (choose different tonnage according to product size) -Testing equipment: three-coordinate measuring machine, two-dimensional imaging instrument, roughness meter, hardness tester, caliper and gauge 5. post-processing services -Mold post-treatment: quenching and tempering, nitriding treatment, coating treatment, polishing, texture processing (etching), sandblasting, improve mold hardness, wear resistance, service life and surface quality. -Product post-processing: deburring, trimming, cleaning, spraying, electroplating, screen printing, assembly, packaging, to meet the product appearance, assembly and use requirements. 6. Order Delivery Time -Standard plastic injection mold: 15~35 days -Precision/multi-cavity mold: 30~60 days -Large/complex molds: 45~90 days -Urgent small mold: 7~20 days
