Mature Technology, Reliable Quality
Manufactured through standardized processes, our molds offer a service life of over 100,000 cycles. They are compatible with aluminum/magnesium alloy die casting processes, ensuring excellent surface finish and internal density for gearbox housings.
Flexible Customization, Rapid Response
We support custom processing according to drawings or joint development, catering to the needs of transmission housing die casting molds for passenger vehicles, commercial vehicles, construction machinery, and more.
Transparent Pricing, Delivery Assurance
As a direct supplier from our own factory, we eliminate middleman markups. The lead time for regular molds is 30-45 days, and urgent orders can be expedited for faster processing.
Our process flow emphasizes practicality and efficiency, ensuring customers obtain high-quality molds at reasonable costs:
1. Requirement Confirmation
Based on the customer-provided transmission housing drawings or samples, confirm material specifications, dimensions, and technical requirements.
2. Mold Design
Use CAD/UG software for 3D structural design, with focus on optimizing the gating system and cooling system.
3. Material Preparation
Select H13 high-quality tool steel, pre-treated via forging to enhance thermal fatigue resistance.
4. Rough Machining
Process the mold prototype using milling and lathe machines, reserving allowances for fine machining.
5. Heat Treatment
Quenching & tempering + nitriding treatment to enhance surface hardness and wear resistance of the mold.
6. Precision Machining
CNC precision machining to form the mold, ensuring cavity dimension error ≤ 0.05mm.
7. Assembly & Trial Casting
Assemble components such as mold frames and ejector pins, conduct trial die-casting on machines, and inspect the finished housing products.
8. Surface Treatment
Polishing/sandblasting to improve mold demolding performance and extend service life.
Every transmission housing die casting mold undergoes three levels of inspection:
1. Dimensional Inspection
Using a CMM (Coordinate Measuring Machine) to verify against drawing parameters, ensuring 100% compliance with specifications.
2. Trial Casting Verification
Test-cast samples are sent for inspection to confirm indicators such as housing airtightness and structural strength.
3. Durability Testing
Simulate continuous production to record mold stability data and ensure long-term reliable performance.
Our transmission housing die casting molds are widely applicable to:
- Automatic/Manual Transmission Gearbox Housings for Vehicles
- Motor Housings for New Energy Vehicles
- Transmission Components for Agricultural Machinery
- Gearboxes for Industrial Equipment
