Electric injection molding Custom Plastic SPD Enclosure Flame Retardant Injection Molding Manufacturer China
This product utilizes precision injection molding to ensure the plastic enclosure possesses high insulation, strength, and dimensional stability. The specific process is as follows:
- Design Evaluation: Customer provides 3D drawings or samples → Structural Evaluation
- Mold Manufacturing: Steel Selection + CNC + EDM + Polishing + Mold Assembly
- Raw Material Preparation: Flame-retardant engineering plastics such as PC or reinforced PA
- Injection Molding: Temperature and pressure are controlled using a high-precision injection molding machine
- Mold Release and Inspection: Appearance and dimensional inspection is performed after automatic mold release
- Post-Processing: Coding, Laser Marking, Assembly Check (if required)
- Packaging and Shipping: Packed and shipped according to customer specifications
