Manufacturing Process Insight
1
Mold Flow Analysis

Before production, we simulate the filling process to optimize gate locations, minimizing porosity and air pockets.

2
High-Pressure Die Casting

We use a 400T cold chamber die casting machine with ADC12 aluminum alloy to form the complex shape, including the thin cooling fins.

3
Precision Post-Machining

After casting, the part is transferred to a 4-axis CNC machining center. We mill the mating surfaces and bore the bearing holes to H7 tolerance, ensuring perfect assembly alignment.

Key Features & Benefits
Thermal Management Icon
Thermal Management

Integrated cooling fins maximize surface area for rapid heat dissipation, critical for protecting internal gears.

Weight Reduction Icon
Weight Reduction

Optimized wall thickness reduces overall vehicle weight without compromising durability.

Complex Structure Icon
Complex Internal Structure

Includes cast-in ribs and bosses that would be too costly to produce via machining alone.

Surface Treatment Icon
Surface Treatment

Shot blasting removes flash and burrs, providing a uniform matte texture ready for assembly or painting.

Technical FAQ
Q1: What is the typical mold life?
A1: Our high-quality tool steel molds (H13) typically last for 50,000 to 100,000 shots depending on maintenance.
Q2: Can you control porosity in the casting?
A2: Yes, through vacuum-assist die casting and strict parameter control, we minimize porosity to meet automotive standards.
Q3: Do you offer leak testing?
A3: Absolutely. We can design custom fixtures to perform air decay leak testing on every housing.
Q4: What machining tolerances can be achieved on critical dimensions?
A4: With our 4-axis CNC machining centers, we routinely achieve precision tolerances down to H7 for bearing bores and ±0.01mm for critical mating surfaces.
Q5: What secondary surface treatments are available besides shot blasting?
A5: We provide complete surface finishing options including anodizing, powder coating, chromate conversion, and electroplating based on your project requirements.
Q6: How do you provide Design for Manufacturability (DFM) support?
A6: Our engineering team conducts comprehensive mold flow simulation and structural reviews prior to tooling creation to optimize wall thickness, draft angles, and parting lines.
