Frequently Asked Questions (सामान्य प्रश्न)

The minimum tolerance requirements depend on the size of the product.

For dimensions up to 200mm, tolerances of ±0.1 or better are required.

For dimensions up to 300mm, tolerances of ±0.2 or better are necessary;

and for dimensions up to 500mm, tolerances of ±0.3 or better are expected.

As for draft angles, a minimum of 1 degree is required, but larger angles are preferred for smoother ejection from the mold.

These tolerance specifications are essential to ensure the precision and quality of die-cast products.

50,000 प्रतिस्थापन या नवीनीकरण से पहले के शॉट्स. If the old die-casting mold reaches the end of its service life, we can replicate a new mold for you free of charge.

कोल्ड चैंबर डाई कास्टिंग: This method is suitable for materials with higher melting points like aluminum and magnesium. The metal is melted in a separate furnace and then injected into the cold chamber machine. It’s ideal for casting durable and lightweight parts but can be a bit slower due to the need for metal transfer.

हॉट चैंबर डाई कास्टिंग: Designed for materials with lower melting points, such as zinc. In this process, the metal remains in a molten state within an integrated furnace connected to the machine. Hot chamber die casting is faster and more efficient for casting smaller, जटिल भाग, making it cost-effective for high-volume production.

Our mold prices are fair and reasonable, and we don’t aim to profit excessively from our customers on mold costs. Moreover, for customers with large order volumes, in the event that a mold becomes unusable, we offer the option of creating a new mold at no additional cost. इसके अतिरिक्त, factors contributing to the pricing of molds include the strength and material selection in the mold design.

Sustainability is a key consideration in our operations. We prioritize sustainable practices by minimizing waste, recycling materials, and implementing energy-efficient processes. Here at Bian, for the sake of material purity, our company utilizes a central melting furnace for the concentrated melting and refining of recycled materials before their reuse. We enforce strict control measures throughout the aluminum die casting process, including incoming raw material inspections, periodic testing of material composition every two hours, and regular third-party testing.

We hold several certifications that attest to our commitment to quality and adherence to industry standards. These certifications include ISO 9001 for quality management, ISO 14001 for environmental management, and IATF 16949, which is specific to the automotive industry. These certifications provide B2B clients with confidence in our processes and our ability to consistently deliver high-quality products.
