Your Reliable Partner for Precision Die Casting Solutions

We’re more than a die casting supplier – we’re your trusted manufacturing partner, combining advanced engineering with strict quality control to deliver durable, high-precision components for automotive, electronics, and industrial applications.
Dimensional Precision: Achieve tight tolerances up to ±0.1mm with 100% QC inspection before shipment.
Material Versatility: Work with premium materials such as ADC12, A380, A360, and Zinc #3/#5 to ensure structural integrity and performance.
Long Mold Life: Durable molds with a lifespan of up to 500,000 shots reduce long-term production costs.
Surface Finishing: Powder coating, polishing, plating, and sandblasting options enhance corrosion resistance and appearance.
One-Stop Production: Die casting, finishing, and assembly all handled internally for better quality control and efficiency.
Certified Quality: ISO 9001:2015 certification ensures global-standard quality, reliability, and full production traceability.

At BIE, getting your die casting parts made is efficient and hassle-free:
Send Your Design: Upload your 3D file (STEP, STP, IGES, DWG, etc.) along with your material, finish, and quantity requirements.
Get a Quick Quote: Our engineers review your design, conduct manufacturability checks, and provide a detailed quote within hours.
Mold Design & Fabrication: Once confirmed, we start mold design and production.
Trial Casting: Perform sample casting to validate flow, surface finish, and dimensional accuracy before mass production.
Quality Inspection: Each casting is measured and tested to ensure it meets ±0.1mm tolerance, with full inspection reports provided.
Shipping: Approved samples or production batches are securely packed and shipped.

We adhere to rigorous technical specifications to guarantee consistent quality:

Each project undergoes a design-for-manufacturability (DFM) review to ensure optimized flow, cooling, and ejection during casting—reducing defects and improving surface finish.

BIE’s die casting solutions serve a wide range of industries where strength, precision, and lightweight performance are critical:
Automotive Industry
Engine housings, gearbox covers, brackets, and heat-dissipating components that withstand vibration, high temperature, and mechanical stress.
