Product Description
OEM Aluminum Die Casting Components for Industrial Equipment

Aluminum die casting is a highly efficient manufacturing process ideal for producing high-performance machinery parts. It involves injecting molten aluminum alloy under high pressure into a steel mold (die), resulting in components with complex geometries, high dimensional accuracy, and excellent mechanical properties.

Key Advantages
  • High Strength-to-Weight Ratio: Significantly lighter than steel or iron, improving energy efficiency.
  • Durability and Corrosion Resistance: Robust parts with a natural protective oxide layer.
  • Superior Precision: Tight tolerances and excellent dimensional accuracy for seamless integration.
  • Good Thermal Conductivity: Efficiently dissipates heat for engine and motor components.
  • Cost-Effectiveness: Economical for high-volume production with minimal material waste.

Frequently Asked Questions
1. Are you IATF 16949 certified and can you provide PPAP?
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 and compliance.
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?
Absolutely. We offer free DFM analysis using Moldflow simulation to optimize wall thickness, gating, and cooling before any tooling begins.
4. What are your lead times for molds?
Mold fabrication typically takes 30-45 days. Once the mold is ready, we deliver first-article samples within 7-10 days for validation.
5. What machine tonnage do you have?
Our facility houses 280T to 900T machines. We support low-volume prototyping and seamlessly scale up to high-volume mass production.
6. What is your MOQ for trial orders?
While our standard mass production MOQ is 500-1,000 pieces, we accept trial orders as low as 100 pieces to help validate your design and market fit.
