Product Specification

OEM/ODM Custom High‑Pressure Die Casting Mold – Aluminum ADC12 & Zinc Zamak Alloy for Auto Parts Production

This OEM/ODM custom high‑pressure die casting mold is engineered to produce auto parts from both aluminum ADC12 and zinc Zamak alloys, offering flexible material options within a single tooling platform. Each mold is precision‑machined from premium hot‑work steel, featuring multi‑cavity layouts, flow‑optimized runners, and balanced ejection systems. Designed to withstand the rapid injection pressures and thermal cycles of modern die casting machines, the mold delivers repeatable dimensional accuracy and high surface finish. Whether your automotive component requires the lightweight strength of ADC12 aluminum or the ductility of zinc Zamak, this custom tooling solution ensures consistent quality and long production runs.

Features

1. Dual‑Alloy Compatibility – One mold design can be adapted for ADC12 aluminum or zinc Zamak alloy, giving manufacturers the freedom to switch materials without retooling.
2. OEM/ODM Custom Geometry – Cavities, cores, sliders, and inserts are fully tailored to your auto part drawing, including complex undercuts and threaded features.
3. High‑Pressure Endurance – Built with heat‑treated H13 or equivalent steel to resist erosion, heat checking, and cracking under 500‑1000 bar injection pressure.
4. Precision Cooling Circuits – Conformal or drilled channels shorten solidification time, reduce cycle periods, and minimize sink marks on thick‑wall sections.
5. Automotive‑Grade Surface Finish – Polished cavities and venting systems produce parts with smooth, plating‑ready surfaces, reducing secondary polishing steps.

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

• Engine Bay Components – ADC12 aluminum brackets, thermostat housings, and sensor mounts that require heat resistance and lightweight construction.
• Door Lock Assemblies – Zinc Zamak latch parts, key cylinders, and locking mechanisms with fine detail and wear resistance.
• Lighting System Housings – Headlight reflectors and fog lamp brackets cast in ADC12 for thermal management and structural stability.
• Interior Trim & Handles – Zinc alloy door handles, window crank bases, and gear shift levers with decorative chrome‑plated finishes.
• Under‑Hood Structural Parts – Engine covers, oil pan sections, and mounting plates in ADC12, balancing strength and weight reduction.
