Product Specification

 Custom Large High Pressure Die Casting Mould  Zinc & Aluminum Alloy Tooling for Hardware Metal Part

This custom large high‑pressure die casting mould is engineered for producing oversize hardware metal components from both zinc and aluminum alloys. Designed to fit large‑tonnage die casting machines, the mould features generously proportioned cavities, reinforced cores, and heavy‑duty slide systems. The tooling is machined from premium H13 or equivalent steel, with heat treatment to withstand the extreme clamping forces and repeated thermal shocks of high‑pressure casting cycles. Advanced flow simulation ensures balanced filling of large cavities, minimizing porosity and internal stress. Whether your hardware part requires the impact resistance of zinc or the light weight of aluminum, this large‑format mould delivers consistent precision over extended production runs.

Features

1. Large Cavity Capacity – Accommodates hardware components weighing several kilograms or measuring over 500mm in length, with multi‑slide support for complex geometries.
2. Dual‑Alloy Flexibility – The same mould base can be configured for zinc alloy (Zamak) or aluminum alloy (e.g., ADC12, A380), adapting to different material properties.
3. High‑Pressure Robustness – Reinforced mould plates and guide pillars resist deflection under injection pressures exceeding 800 bar, ensuring part consistency across large surface areas.
4. Optimized Gating for Large Parts – Multiple fan gates or ring runners distribute molten metal evenly, preventing cold shuts and weld lines in big hardware castings.
5. Efficient Heat Extraction – Custom‑drilled cooling circuits near thick cross‑sections shorten solidification time, improving cycle efficiency and reducing sink marks.

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

• Heavy‑Duty Hardware Handles – Zinc alloy door handles, latches, and industrial pull bars requiring high impact strength and plated finishes.
• Aluminum Gearbox Housings – Large enclosures for agricultural machinery or construction equipment, cast in aluminum for weight savings
• Industrial Caster Frames – Load‑bearing brackets and swivel housings for heavy‑duty wheels, demanding both strength and corrosion resistance.
• Hydraulic Pump Bodies – Large‑format aluminum castings with integrated oil channels and mounting flanges for high‑pressure systems.
