Custom High-Pressure Aluminum Die-Casting Molds Precision Tooling for Production Casting

These custom high-pressure casting molds are precision-engineered for aluminum die-casting operations, delivering durable tooling solutions tailored to your specific component geometries. Each mold is machined from premium-grade hot-work steel, with cavity designs optimized for rapid cavity fill, controlled solidification, and clean part ejection. Built to withstand injection pressures exceeding 800 bar and thousands of thermal cycles, our molds produce aluminum parts with consistent dimensional stability, fine surface detail, and minimal porosity. From initial design consultation to final tryout, we provide a complete custom molding service that aligns with your production volume and quality targets.

Features

1. Tailored Cavity Geometry – Every mold cavity is machined to match your 3D model exactly, including complex ribs, bosses, and undercuts using slide or lift cores.

2. High-Pressure Endurance – Constructed from H13 or DAC steel with vacuum heat treatment to resist heat checking, erosion, and plastic deformation under extreme injection forces.

3. Optimized Filling Paths – Runner and gate designs verified by flow simulation software to reduce air entrapment, cold shuts, and flow marks on finished castings.

4. Integrated Cooling System – Drilled or conformal cooling channels arranged to balance die temperature, shorten cycle times, and improve part consistency.

5. Pre-Production Sampling – Each mold undergoes trial casting on your specified press, with sample parts measured and reported before final approval.

Our Advantages
1. We are the biggest lost foam mould manufacturer in China, we focus on high challenge lost foam mould and we have large gantry machining centers,30 sets imported high speed machining center,more than 40 sets general machine tool equipment;
2. We have 36 senior mould designers, to ensure reasonable / safety / high efficiency mould design and ensure the fast mould delivery and rational mould structure, make the process more safer and the production efficiency more higher;
3. We using numerical control machine tool to manufacture the mould cavities, to ensure a even thickness ;
4. We using ZL104 Aluminium to casting the mould, to manufacture a high strength mould;
5. For the big mould, we using Ø22*1 copper tube as cooling pipe, with water spray system, to get a nice cooling effect;
6. We Have (TEF10N) coating on the mould surface, it can reduce the friction, anti water/static electricity/acid-base/high-temperature, with this we can ensure the pattern has smooth surface without distrotion, and easy to demould;
7. All the screws we using stainless steel screw, easy to disassemble during maintenance;
8. For the big mould chest, we using 18-20mm thick wrought aluminium plate, to offer high strenght cavity.

Product Process

The research and development center is consist of 36 designers who are expert in 3D design, mold design, NC programming craftsmen, lost foam casting craftsmen and so on. We provide a full range of design and services for you. We discuss the mould process and confirm the scheme with your engineer together, this can guarantee the mould structure more reasonable more safety and more efficiency. We finish the product model and detection through reserve scan and 3D Coordinate Measuring technology to make sure each customer satisfy their mould.

Applications

• Automotive Powertrain Housings – Transmission cases, clutch housings, and differential covers requiring pressure tightness and structural rigidity.

• LED Luminaire Heat Sinks – Intricate fin arrays with thin walls, demanding smooth ejection and excellent thermal transfer from the mold.

• Industrial Servo Motor Enclosures – Cylindrical or rectangular housings with integrated mounting flanges and precision connector ports.

• Aerospace Interior Components – Lightweight aluminum brackets and seat tracks where weight reduction and fatigue resistance are critical.

• Hydraulic Manifold Blocks – Complex internal passageways cast cleanly, avoiding core shift and ensuring leak-free operation under pressure.
