Automated 18-Color Micro-Injection Molding Engineering Deep Dive
How computerized dispensing and precision CNC tooling enable complex multi-layer designs without color bleed.
1. Evolution from Manual Dispensing to 18-Color Robotic Automation
Traditional promotional gift factories rely on manual syringe workers to fill small color crevices in PVC molds, leading to inconsistent color weights, surface bubbles, and registration drift. In contrast, NAIKE GLOBAL operates 45 computerized micro-injection lines capable of dispensing up to 18 distinct Pantone colors simultaneously.
Each dispensing needle is driven by a 3-axis CNC gantry system with optical position recognition, ensuring repeatable dispensing volumes as small as 0.02 ml per cavity.
2. The 5-Stage Micro-Injection Manufacturing Process
| Stage | Process Step | Key Quality Metric |
|---|---|---|
| Stage 1 | CNC Mold Engraving | Aluminum or copper molds engraved at 0.05 mm tool bit radius for crisp parting boundaries. |
| Stage 2 | Color Dispensing | Computerized pneumatic needles dispense fluid PVC into fine graphic grooves. |
| Stage 3 | Pre-Bake Curing | Mold travels through radiant infrared oven at 180°C to semi-cure the top decorative layers. |
| Stage 4 | Backing Layer Pour | Base body material poured to full thickness and backed into a solid integral structure. |
| Stage 5 | Water Quenching | Rapid water cooling bath solidifies the part, allowing distortion-free demolding. |
