Working With a Shenzhen Stamping Factory? Ask These 5 Questions First

Most sourcing surprises come from five questions that were never asked up front. Ask them early and the whole project runs smoother.
Are My Drawings Complete?
Material, thickness, tolerance, surface finish and quantity - missing any one item delays quoting.
What Is the Quantity, Really?
Annual volume decides whether a die-based process makes sense.
How Is Die Cost Shared?
Is tooling paid up front, amortized into the unit price, or owned by the customer?
How Do Sampling and Pilot Runs Work?
Agree on sample quantity, lead time and who approves first article.
How Are Inspection and Lead Time Split?
Define the inspection standard and the milestone dates before production starts.
