Precision Aluminum Die-Cast Automotive Parts

Engineering Excellence for the Automotive Sector

In the automotive industry, procurement managers and product engineers face rigorous demands: reducing vehicle weight, ensuring strict dimensional tolerances, and mitigating the risk of component porosity. At NINGBO ZHENHAI BOLANG METAL PRODUCT FACTORY, we understand that a single micro-crack can halt an assembly line.

Since 2001, we have optimised our aluminium die-casting process to meet these exact challenges. We specialise in complex geometries using premium alloys like A380, ADC12, and A356, providing a superior strength-to-weight ratio critical for modern electric (EV) and combustion vehicles.

• Porosity Eradication: Advanced vacuum die-casting and precise thermal control significantly reduce gas entrapment.
• Stringent Tolerances: Multi-axis CNC machining centres ensure dimensions are held to tightest tolerances, ready for assembly.
• Full Traceability: Complete PPAP (Production Part Approval Process) documentation aligned with strict automotive supply chain protocols.

Uncompromising Quality Assurance & IATF16949

To serve Tier 1 automotive clients across the USA, Europe (England, Germany, Italy), and Asia, maintaining an impeccable defect rate is not optional; it is mandatory.

Bolang has successfully passed the IATF16949:2016 quality management system certificate, alongside ISO14001:2015 and ISO45001:2018. Our dedicated testing laboratories validate every batch of raw material and finished product.

• Coordinate Measuring Machines (CMM): For exacting geometric dimensioning and tolerancing (GD&T) verification.
• Spectrometer Testing: Verifying the chemical composition of raw aluminium alloys (e.g., A380, YL102) prior to casting.
• Custom Leak Testing: Self-designed pneumatic testing fixtures for critical sealed automotive components.
• 3D Scanning & X-Ray: Non-destructive testing to detect internal voids and ensure structural integrity.
