Why Choose Us
One-Stop, End-to-End
Mold design and manufacturing, low-pressure die casting, CNC machining, and heat treatment are all performed in-house, ensuring full control over quality and delivery times throughout the entire process.
Rapid Prototyping and Validation
We support drawing reviews and small-batch prototyping. The prototyping cycle is approximately 【Please fill in, e.g., 15】 days. We validate the design before moving to mass production.
High-Density Castings
The pressure-holding and shrinkage compensation process, combined with directional solidification, results in castings with low porosity and a dense microstructure, meeting the strength requirements for structural components.
Transparency Audits
Material certificates and inspection records are provided with each shipment; all critical dimensions of 100% are subject to 100% inspection, and the reports are delivered with the goods.
Common Casting Aluminum Alloys
| material grade | specificities | typical application |
|---|---|---|
| A356 / A356.2 | Well-balanced overall properties, good casting fluidity, and capable of T6 heat treatment for strengthening | Wheels, chassis structural components, engine parts |
| AlSi7Mg0.3 | High strength, good weldability, and excellent toughness after heat treatment | Suspension System, Load-Bearing Brackets |
| AlSi10Mg | Excellent flow properties and thermal conductivity; suitable for complex thin-walled structures | Battery housing, motor housing, heat dissipation components |
Material composition and mechanical properties shall comply with the standards [Please specify, e.g., GB/T 15115 / ASTM B26]; alloys can be customized according to drawing specifications.
