CUSTOM PLASTIC INJECTION MOLDING
We provide high-precision plastic injection molding services tailored to meet strict requirements in terms of dimensions, appearance, materials, and production volume — serving a wide range of industries such as office equipment, electronics, medical devices, automotive & motorcycles, and high-end consumer goods.
Professional Technical Team
Our injection molding technicians are well-trained and experienced, working with a wide variety of materials including ABS, PC, PA66, POM, TPE, flame-retardant plastics, and medical-grade resins
Skilled operation across multiple injection molding machine types, with parameter optimization to achieve:
- High dimensional accuracy
- Smooth, flawless product surfaces
- Fast and stable production cycles
QC & QA departments conduct inspections in compliance with ISO 9001 standards
- Measurement using digital metrology tools
- Visual inspection based on part-specific checklists
- Data storage and reporting for each production batch
D-Pro S
We apply the D-Pro S software to manage products in a synchronized and professional manner. Each product is assigned a unique identification code, with complete records of materials, Lot/No., drawings, inspection standards, and direct linkage to purchase orders and production schedules — ensuring compliance with requirements and timelines. All technical changes are clearly documented and easily traceable. The system also integrates QC/QA quality control, attaching checklists and measurement results to each product code, fully meeting traceability requirements in accordance with ISO 9001 standards.
Modern Injection Molding Equipment
The entire injection molding line is fully synchronized and highly automated, ensuring stable quality, flexible production, and cost optimization.
| Equipment | Description & Function |
|---|---|
| Plastic Injection Molding Machines (7 – 450 tons) | Suitable for ultra-small products, thin-wall parts, large components, and complex precision parts. |
| Plastic Dryer – Dehumidifier | Ensures dry, clean, bubble-free materials – optimizing the surface quality of finished products. |
| Mold Cooling System | Stabilizes temperature, enables precise molding, and prevents shrinkage and dimensional deviations. |
| Automatic Pick-and-Place Robot | Reduces labor, increases speed, and minimizes scratches and deformation during product removal. |
| Industrial Camera & AI System | The device is installed directly at the end of the production line, capable of real-time scanning, analysis, and defect detection with near-perfect accuracy. |
| Product & Customer Information Management with D-Pro S | Assigns unique identification to each product code, stores technical data, links purchase orders – production plans – and quality control to each order; enables easy traceability of. |
