The Alloy Repository: Strategic Material Selection
Choosing the correct aluminum grade is a balance of ductility, thermal conductivity, and weight. Below is a comparative analysis of our core automotive materials.
| Alloy Grade | Standard | Tensile (MPa) | Best Used For |
|---|---|---|---|
| ADC12 | JIS H5302 | 310 | High-fluidity housings & structural brackets |
| A380 | ASTM B85 | 325 | Premium engine components & oil pans |
| AlSi10Mg | DIN 1725 | 240 | Ductile structural parts requiring T6 treatment |
Engineering Authority: Why Vacuum Matters
In the production of high-precision aluminum die casting products, the presence of air in the mold cavity is the primary cause of internal defects. When molten aluminum is injected at high speed, it traps air, leading to “porosity.” This is particularly critical for parts like engine oil pans or water pump casings that must be pressure-tight.
Our Malaysia and China facilities utilize multi-stage vacuum extraction. By removing the air 0.5 seconds before the shot, we ensure the metal occupies every micro-void of the die. This results in a dense, pore-free grain structure that allows for heat treatment and superior surface finishing, such as chrome plating or high-adhesion powder coating.
Industrial Knowledge Base: Strategic FAQ
What is the guaranteed mold life for 150k+ production?
For high-volume products (e.g., Automotive), we use certified H13 steel with vacuum heat treatment. We guarantee a mold life of 100,000 to 150,000 shots depending on part complexity. For larger volume contracts, Bolang subsidizes replacement tooling.
Are your aluminum alloys RoHS and REACH compliant?
Yes. All aluminum ingots (ADC12, A380, AlSi10Mg) sourced by Bolang Casting come with Mill Certificates verifying they are free from conflict minerals and fully compliant with EU RoHS and REACH directives for export.
Do you handle magnesium die casting in Malaysia?
Currently, our Malaysia facility focuses exclusively on Aluminium and Zinc die casting to prevent cross-contamination. Magnesium casting is available through our specific partners in Ningbo under our strict supervision.
Can you perform in-house powder coating?
Yes. Our product lines include automated powder coating and wet painting lines. We regularly test for Salt Spray resistance (up to 1000 hours for Agri-parts) and cross-cut adhesion (ISO Class 0) to ensure durability.
