What Are Customized Mold Solutions?
Customized mold solutions refer to the design, engineering, and production of specialized tooling systems that shape raw materials into precise components through various manufacturing processes. Unlike standard molds, customized solutions are tailored to specific product requirements, materials, and production environments.
The Mold Manufacturing Process
- Design Phase (3-7 days)
- CAD modeling
- DFM (Design for Manufacturing) analysis
- Mold flow simulations
- Machining Phase (2-4 weeks)
- CNC milling (accuracy up to ±0.005mm)
- EDM (Electrical Discharge Machining)
- High-speed machining
- Testing & Validation (1-2 weeks)
- Trial shots
- Dimensional verification
- Production optimization
Types of Custom Molds
| Mold Type | Tolerance | Typical Lifespan | Best For |
|---|---|---|---|
| Prototype Molds | ±0.1mm | 5,000-10,000 shots | Low-volume testing |
| Production Molds | ±0.02mm | 500,000+ shots | Mass production |
| Multi-cavity Molds | ±0.01mm | 1M+ shots | High-volume small parts |
| Hot Runner Molds | ±0.015mm | 300,000+ shots | Reduced material waste |
