Custom High Quality Mold Making Service Pressure Gravity Metal Aluminum Alloy Die Casting CNC Mold Moulds

This custom high quality mold making service specializes in producing both pressure and gravity die casting moulds for aluminum alloy components. Using advanced CNC machining and EDM processes, we craft moulds that accommodate either high-pressure injection or gravity-fed permanent mold casting methods. For pressure die casting, our tools feature hardened steel cavities, precision runners, and efficient cooling circuits to withstand rapid cycles and high clamping forces. For gravity die casting, we design robust, heat-resistant molds with controlled venting and smooth taper angles for easy part release. Whether your production requires the speed of pressure casting or the density of gravity casting, our CNC-machined moulds deliver consistent dimensional accuracy, long service life, and excellent surface finish for aluminum alloy parts.

Features

• Dual Process Capability – One mold design service covers both high-pressure injection casting and gravity permanent mold casting, tailored to your production method.
• CNC Precision Machining – 5-axis CNC and wire EDM ensure tight tolerances down to ±0.01mm on cavity surfaces, cores, and sliders.
• Aluminum Alloy Optimized – Moulds engineered specifically for aluminum alloys, with proper draft and venting for each alloy’s flow characteristics.
• End‑to‑End Service – From part design review, flow simulation, and mould manufacturing to sample casting and process tuning, all under one roof.

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

1. Automotive Suspension Arms – Gravity die cast moulds for A356 aluminum control arms requiring high ductility and T6 heat treatability.

2. Pressure Cooker Bodies – High pressure die casting moulds for ADC12 lids and bases, demanding smooth surfaces and leak-proof threads.

3. LED Housing Heat Sinks – Fine‑finned enclosures cast via pressure die casting for rapid heat dissipation.

4. Industrial Gear Covers – Gravity cast enclosures for heavy machinery, where dimensional stability over large areas is essential.

5. Marine Hardware Components – Corrosion-resistant aluminum brackets and pulleys cast using either process, with moulds designed for salt‑spray durability.
