Automotive Grade Aluminum Die Casting

Aluminum die casting has become a cornerstone manufacturing process in the automotive industry. Designed for the rigorous demands of the automotive and aerospace industries, our facility delivers certified aluminum die castings with full traceability. Our 900T capability allows for large, structural components such as EV battery housings and structural nodes with exceptional integrity.

Technical Capabilities

Vacuum Die Casting: Reduces air entrapment to <3%, suitable for leak-tight parts and heat treatment (T6/T7).
Squeeze Pin Technology: Ensures dense microstructure for high-pressure applications.
Leak Testing: 100% helium or air decay leak testing available (up to 20 bar).
X-Ray Inspection: In-house X-ray detection for internal porosity analysis.
Material Traceability: Full heat-number tracking from ingot to finished part.

Workshop & Production Process

Step-by-Step Production:

1. DFM Analysis: Reviewing 3D drawings for manufacturability.
2. Mold Making: Precision mold fabrication (30-45 days).
3. Die Casting: High-pressure injection with real-time monitoring.
4. CNC Machining: Trimming, drilling, tapping, and milling.
5. QC & Packaging: Final inspection (CMM) and secure export packaging.

Frequently Asked Questions

1. Are you IATF 16949 certified, and can you provide PPAP documentation?

Yes. We are fully IATF 16949 certified and provide complete PPAP Level 3 packages (including PFMEA, Control Plans, MSA, and SPC) to ensure full traceability.

2. What is your quality control process?

We guarantee a production yield rate over 98%. Our QC includes raw material spectrometer analysis, real-time casting monitoring, and 100% dimensional inspection via CMM.

3. Do you provide free DFM analysis before mold making?

Absolutely. We offer free DFM analysis using Moldflow simulation to optimize wall thickness and cooling, preventing defects before tooling begins.

4. What are your lead times for mold and samples?

Mold fabrication typically takes 30-45 days. Once the mold is ready, we deliver first-article samples within 7-10 days for your validation.

5. What machine tonnage do you have available?

Our facility houses 280T to 900T machines. We support low-volume prototyping (MOQ 100 pcs) and scale up to high-volume mass production.

6. Is CNC machining and surface finishing done in-house?

We offer a true One-Stop Solution. All secondary processes, including 3/5-axis CNC machining, are handled in-house for better quality control and faster turnaround.
