The quality of your cast part starts with the mold. We engineer the perfect molds utilizing advanced UG/NX design and Moldflow simulation. We create durable, high-efficiency dies optimized for 280T-900T machine ranges, ensuring minimal cycle times and maximum tool life.
Key Design Principles:
| Parameter | Details |
|---|---|
| Mold Base Material | LKM, HASCO, DME Standard Bases (P20, 718, H13 Core/Cavity) |
| Cavity Hardness | HRC 46-52 (Nitrided/Hardened) for extended life (>300,000 shots) |
| Design Software | UG NX, Pro/E, AutoCAD; Full 3D Mold Flow Analysis included |
| Cooling System | Conformal cooling channels designed for uniform heat dissipation |
| Lead Time | 30-45 Days (From drawing approval to T1 Sample) |
| Common Defects | Prevention via Mold Design |
|---|---|
| Porosity | Improve venting, optimize gating to reduce turbulence, use cooling channels. |
| Shrinkage | Design uniform walls, use chills to accelerate cooling in thick sections. |
| Cold Shut | Increase mold preheating temperature, optimize injection speed and pressure. |
| Warpage | Optimize cooling channel layout and add ribs to reinforce the part structure. |
| Pain Points | Our Solutions |
|---|---|
| Unclear Responsibility | Full Accountability: We oversee the entire process from raw materials to finished goods. |
| Slow Response | Quick Decisions: Dedicated managers make on-the-spot decisions for urgent requirements. |
| High Hidden Costs | Cost-Optimized: Direct investment in production and QC—you pay for product value. |
| Inefficient Coordination | Single Point of Contact: Direct communication end-to-end to ensure project efficiency. |
Established in 2004, our facility has grown into a strategic partner for global brands seeking high-integrity aluminum components. Located in the heart of the die-casting industry, we combine two decades of manufacturing heritage with modern quality management systems.
