Frequently Asked Questions: Zinc Pressure Die Casting in China

Q: What is zinc pressure die casting and how does it differ from aluminum die casting?

Zinc pressure die casting injects molten zinc alloy under high pressure into a hardened steel die, producing near-net-shape components with excellent dimensional accuracy and smooth surface finish. Zinc alloys (especially Zamak grades) melt at around 380–390 °C — far lower than aluminum's 660 °C — so they are processed in faster, more efficient hot-chamber machines. Aluminum die casting uses cold-chamber machines and is preferred for lightweight structural parts. Zinc excels where fine detail, thinner walls, longer die life, and lower unit cost are the priorities.

Q: Which zamak alloy should I specify for my zinc die cast part?

Zamak 3 is the most widely used, offering the best balance of strength, ductility, and dimensional stability for general hardware. Zamak 5 adds ~1% copper for higher strength, preferred for automotive and mechanical parts. Zamak 8 provides the highest hardness and wear resistance among standard Zamak grades. For elevated strength or temperature requirements, ZA-8, ZA-12, and ZA-27 alloys are also available. Always consult your supplier's DFM team to match alloy selection to your wall thickness, draft angles, and surface finishing needs.

Q: What certifications should I require from a Chinese zinc die casting supplier?

Require ISO 9001 as a baseline. For automotive supply chains, IATF 16949 is mandatory, covering APQP, PPAP, and FMEA. Medical applications may additionally require ISO 13485. Always request a PPAP Level 3 package — including dimensional reports, material certifications, and process control plans — before approving production.

Q: What is a typical MOQ and lead time for zinc pressure die casting in China?

Most suppliers accept MOQs of 500–1,000 pieces per run after tooling is amortized, with prototype runs as low as 50–200 pieces. New tooling (T1 samples) typically takes 3–6 weeks; production after tooling approval runs 2–4 weeks depending on volume. Suppliers with in-house mold shops tend to offer shorter combined lead times.

Q: How do I evaluate a Chinese zinc die casting supplier during the RFQ process?

Request: (1) quality certifications; (2) DFM analysis capability; (3) CMM and inspection equipment list; (4) a sample PPAP or first-article report from a comparable part; (5) industry references or case studies. For critical applications, consider an on-site audit or third-party factory assessment before committing to tooling investment.
