IATF 16949 Certified Automotive Die Casting Solutions
Tier-1 Integrity. Zero Porosity in Safety-Critical Components.
Dual-Shore Manufacturing (China & Malaysia) for Tariff-Free Supply Chains.
Bridging Engineering Precision with Procurement Strategy
In the automotive sector, component failure is not an option, and supply chain fragility is a liability. Bolang bridges the gap between the Product Engineer’s demand for zero-defect metallurgy and the Procurement Manager’s need for cost stability.
- ❌ The Engineer’s Pain: Sub-surface porosity in thick-wall chassis parts leading to structural failure under stress.
- ❌ The Buyer’s Pain: Unpredictable tariffs (Section 301) and fragmented logistics causing line-down risks.
- ✅ The Bolang Solution: A unified Turnkey Manufacturing Model that integrates vacuum-assisted casting precision with a dual-shore tariff mitigation strategy.
Specialised Automotive Application Modules
From ICE powertrains to New Energy Vehicle (NEV) thermal management systems.
🔋 EV Thermal Management
For Inverters, On-Board Chargers (OBC), and Battery Housings.
The Challenge: Heat dissipation density. Standard A380 alloy often traps heat.
Our Solution: We utilise AlSi10Mg alloy (thermal conductivity >150 W/m·K) combined with high-vacuum casting to produce thin-wall cooling fins (down to 1.5mm) without cold shuts. This mirrors the thermal efficiency standards we apply in our High-Performance LED Heatsinks.
⚙️ Powertrain & Transmission
For Oil Pans, Valve Bodies, and Transmission Housings.
The Challenge: Fluid leakage under high pressure.
Our Solution: 100% Air Decay Leak Testing implemented inline. We achieve leak-proof density through multi-stage vacuum valves that evacuate air 0.5s before injection, ensuring porosity stays below 0.8%—crucial for hydraulic integrity similar to our Industrial Hydraulic Components.
🛡️ Body & Chassis Structure
For Shock Tower Mounts, Brackets, and Mirror Bases.
The Challenge: Impact resistance and ductility.
Our Solution: Primary alloys with low iron content to maximise elongation (>3%). Our 800T machines handle thick-wall sections (up to 53mm) with uniform internal density, verified by X-Ray and destructive testing.
The “Automotive Integrity” Protocol
Compliance is not just a certificate; it is a forensic process. We adhere to strict quality gates at every stage of production.
1. Porosity Control Strategy
We do not rely on chance. Utilising 50 mbar vacuum systems and precise thermal regulation of the mould (H13 steel), we eliminate air entrapment in complex geometries. This is verified via section cuts and X-Ray analysis.
2. Dimensional Certainty (CMM)
Our in-house Zeiss CMM labs in both Ningbo and Malaysia ensure positional tolerances of ±0.005mm are maintained for critical bearing seats and sensor mounts.
3. VDA 19 Cleanliness Standards
For sensitive electronic housings (ECU/TCU), particulate contamination causes failure. Our industrial ultrasonic cleaning lines remove non-conductive particles, coolant, and oils to meet strict OEM residual dirt analysis standards.
4. Surface Durability
We employ the Boiling Water Cross-Cut Test to simulate extreme humidity and temperature cycling, ensuring coating adhesion never fails in the field.
