IATF 16949 Certified Die Casting Services

Why Procurement Managers & Engineers Choose Bolang

For over 20 years, Bolang Casting has bridged the gap between complex engineering requirements and supply chain stability. We serve Tier-1 automotive and industrial clients across North America (70%) and Europe (20%).

1. Supply Chain Resilience (China + Malaysia)

Mitigate geopolitical risks and tariff barriers with our Dual-Shore Manufacturing Strategy. Our newly established plant in Perak, Malaysia, mirrors our Ningbo HQ’s quality standards.

• Ningbo HQ: High-efficiency tooling & mass production.
• Malaysia Plant: Tariff-mitigation solutions with 320T-800T capacity.
• Seamless Transfer: Unified quality management systems (QMS) allow for flexible production shifting.

2. Solving Porosity in Thick-Wall Parts

Porosity is the enemy of structural integrity. Through advanced flow simulation and rigorous mould design optimisation, we achieve high-density internal structures even in components with wall thicknesses up to 53mm.

Quality Assurance: Beyond the Standard

As an IATF 16949 certified manufacturer, quality is embedded in every stage of our process, from raw material verification to final delivery.

In-House Laboratory Capabilities

We do not rely on guesswork. Our internal lab is equipped to validate material properties and dimensional accuracy:

• Spectrometer: Ensures raw material (Al/Zn) chemical composition matches international standards before casting.
• CMM (Coordinate Measuring Machine): Verifies complex geometries with micron-level precision.
• X-Ray & Air Leak Testing: Critical for verifying internal porosity and pressure tightness in automotive components.
• Physical Testing: Tensile strength and Hardness testing machines.

Traceability & Documentation

We provide full PPAP (Level 3) documentation, Control Plans, PFMEA, and Material Certifications for every batch.

Q: How do you handle mould ownership?

A: You retain 100% ownership of the moulds. Bolang maintains the tooling throughout its lifecycle at no extra cost until the guaranteed shot life is reached.

Q: Can I transfer production to Malaysia later?

A: Absolutely. Our “Dual-Shore” strategy allows for seamless mould transfer between our Ningbo and Perak facilities to adapt to tariff changes or capacity needs.

Q: What is your typical lead time?

A: Standard lead time for T1 samples (including tooling fabrication) is 25-35 days, depending on geometry complexity. Mass production lead times are typically 3-4 weeks.

Q: What file formats do you accept for DFM?

A: We work with STEP, IGES, X_T, and Parasolid for 3D models, and PDF/DWG for 2D drawings ensuring strict tolerance adherence.
