OEM Chassis Housing Casting Service Motorcycle Transmission Parts High Pressure Die Casting Design Mold

This OEM high pressure die casting mold is purpose‑built for manufacturing motorcycle transmission components and chassis housings, combining precision tooling with efficient casting service. The mold featuring multi‑cavity or single‑cavity layouts tailored to complex gearbox shapes, mounting bosses, and oil channels. Advanced gating systems ensure rapid, turbulence‑free filling of aluminum alloy under high pressure, yielding dense, heat‑treatable parts with excellent mechanical properties. From initial flow simulation to sample casting and volume production, our integrated design and service package delivers reliable, high‑integrity molds that meet the demanding strength and wear requirements of motorcycle powertrains.

Features

1. Motorcycle‑Specific Cavity Design – Mold geometry optimized for clutch housings, gearbox shells, and swingarm brackets, including integrated bearing seats and sealing grooves.
2. High Pressure Integrity – Built to withstand injection pressures up to 1,000 bar, ensuring pore‑free castings that pass leak tests for oil‑containing transmission chambers.
3. OEM Custom Service – From part drawing to finished mold, we provide full design support, including gate placement, cooling layout, and ejection pin positioning.
4. Rapid Thermal Cycling – Conformal cooling channels near thick flanges and ribs reduce cycle time by 15‑20% while preventing porosity and distortion.
5. Tryout & Validation Included – Every mold undergoes trial casting using your specified aluminum alloy with full dimensional reporting before delivery.

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. Motorcycle Gearbox Housings – Left and right crankcase covers that require precise mating surfaces and oil‑tight integrity under vibration.

2. Clutch Cover Assemblies – Thin‑wall aluminum die castings with integrated reinforcing ribs and cable routing bosses.

3. Chassis Cross Members – Structural housings that connect engine to frame, demanding high fatigue strength and impact resistance.

4. Starter Motor Housings – Compact, heat‑dissipating enclosures with precise mounting flanges for bolt‑on attachment.

5. Transmission End Caps – Sealed covers incorporating breather ports and sensor mounting pads for modern motorcycle electronics.
