Customize metal die-casting parts

Porosity & Air Pocket Reduction

We use vacuum die casting and optimized venting to minimize trapped gas, ensuring leak-tight performance for pressure-bearing parts.

Thin Wall Filling Issues

Specialized process parameters to ensure complete filling for thin wall parts as thin as 0.8mm, preventing cold shut defects.

Flash & Burr Control

Precision mold manufacturing and optimized clamping force to minimize flash, reducing post-processing work and cost.

Warping After Cooling

Mold flow analysis and temperature control to predict and prevent warpage, ensuring dimensional stability after cooling.

Dimensional Consistency

Process monitoring and automated production to ensure consistent dimensional accuracy across mass production runs.

Leakage Issues in Pressure Parts

Vacuum casting and 100% leak testing to ensure zero leakage for hydraulic, pneumatic, and pressure-containing components.

Gate & Runner Optimization

In our 15+ years of die casting experience, we optimize gate location and runner design to ensure smooth molten metal flow, reducing turbulence and air entrapment, which is critical for complex geometry parts.

Wall Thickness Design

We help you design uniform wall thickness to prevent shrinkage and cold shut defects. We can handle thin walls down to 0.8mm, while ensuring proper filling and solidification to avoid internal voids.

Venting & Overflow Design

Proper venting and overflow wells are essential to trap air and contaminants. For pressure-tight parts, we combine this with vacuum die casting to achieve porosity-free internal structures, passing 100% leak tests.

Mold Temperature Control

Precision mold temperature control ensures consistent cooling, preventing warpage and dimensional variation. We use thermal analysis to balance temperature distribution across the mold, ensuring stable production.

Draft Angle Optimization

We optimize draft angles based on part geometry and surface finish requirements, ensuring smooth mold release without damaging the part surface, reducing the need for additional polishing work.

Assembly

What tolerance can you achieve in die casting?

We can achieve standard tolerance of ±0.05mm for die casting parts, and tighter tolerance can be achieved with secondary CNC machining based on your requirements.

Can you provide leak-proof die cast housings?

Yes, we use vacuum die casting process for pressure-tight parts, combined with 100% leak testing to ensure zero leakage for hydraulic, pneumatic and other pressure-containing components.

How do you reduce porosity in die cast parts?

We use optimized venting design, overflow wells, and vacuum die casting process to minimize porosity. For critical parts, we also perform X-ray inspection to verify internal quality.

Can you support post-machining after casting?

Yes, we provide full secondary operations including CNC machining, tapping, drilling, and various surface treatments, providing you with finished parts ready for assembly.

What file formats do you accept?

We accept all common CAD file formats including STEP, IGES, DWG, DXF, PDF, and also accept 2D drawings or sample parts for custom manufacturing.

How long does die casting tooling take?

Standard die casting tooling takes 15-25 days, depending on the complexity of the part. We can provide expedited tooling service for urgent projects.
