Precision Aluminum Die Cast Small and Medium Motor Housings

Core strengths

Core Technical Advantages
Precision Die Casting Process
We utilize 160T-800T high-speed die casting machines equipped with vacuum assist systems, ensuring housing density ≥98.5%. The flow channel design, optimized specifically for small and medium housings, controls wall thickness uniformity within ±0.2mm, especially suitable for complex heat dissipation structures and thin-wall (2.0-4.0mm) designs.

Material Science
Selection of high-quality aluminum alloys such as ADC12, A380, and AlSi10Mg, providing options for different performance levels:
ADC12: Economical and practical, thermal conductivity 96W/(m·K)
A380: Balanced performance, tensile strength ≥320MPa
AlSi10Mg: High strength requirement, elongation ≥3.5%

Precision Machining Capability
Equipped with multi-axis CNC machining centers, capable of completing machining of critical areas such as end faces, bearing seats, and mounting holes in one step, ensuring:
Bearing seat precision: H7 grade (±0.015mm)
Mounting face flatness: ≤0.03mm/100mm
Positional accuracy: ±0.02mm

Quality Control System
Full-Process Inspection
Raw material testing: Spectroscopic analysis, ensuring compliance with composition standards
Process control: Real-time monitoring of die casting parameters

Frequently Asked Questions 
Q: What is the Minimum Order Quantity (MOQ)? 
A: There is no MOQ required during the sampling phase. For mass production, the MOQ is generally 500-1000 pieces, depending on product complexity.

Q: What surface treatments can you provide? 
A: Anodizing (various colors), powder coating, electrophoresis, micro-arc oxidation, etc. We recommend the most suitable solution based on the application.

Q: How are mold costs calculated? 
A: Costs are evaluated based on product size and complexity. They are usually included in the initial order and may be reimbursed or offset after a certain production volume is reached.

Q: Do you offer in-house machining? 
A: Yes, we provide one-stop service from die-casting to machining, including all processes for bearing seats, end faces, threaded holes, etc.

Q: What is your monthly production capacity? 
A: The monthly capacity for small and medium-sized housing can reach 1 million pieces, which can be flexibly adjusted according to demand.
