❓ Frequently Asked Questions

Expert Answers to Common Procurement and Technical Queries

Q1: What are the primary advantages of Zinc alloy die casting over Aluminum?

A: Zinc alloys (Zamak) offer higher ductility, better impact strength, and allow for thinner wall sections. They also have a lower melting point, which extends mold life significantly. Zinc is ideal for high-precision, decorative parts like bathroom hardware.

Q2: How does Huazhu ensure quality for global OEM contracts?

A: We implement a 100% inspection protocol. Our ISO 9001 and IATF 16949 certifications mean every batch undergoes rigorous testing, including dimension verification (accuracy to 0.02mm) and salt spray testing (up to 480H for extreme environments).

Q3: What is the lead time for a custom die casting project?

A: Mold development typically takes 28 to 35 days. Once the mold is approved, mass production lead times depend on volume but usually range from 15 to 30 days.

Q4: Can you handle surface treatments like PVD and Electroplating in-house?

A: Yes, we manage the entire industrial chain including polishing, electroplating, spraying, and PVD coating. This allows us to maintain strict color consistency and finish quality across all units.
