ANSWERS FOR YOUR PROGRAM

Frequently Asked Questions

What is die casting, and is it right for my part?

Die casting forms metal parts in a reusable steel die. It can suit repeat production of complex aluminum or zinc components. Your volume, geometry, alloy and inspection needs determine whether the tooling investment makes sense.

What affects my die casting quote?

Part size, alloy, wall sections, cavity count, slides, machining, finish, inspection and order volume all affect cost. Share your annual demand and batch size so tooling and recurring part costs can be reviewed together.

Can you support low-volume die casting?

Send your expected quantities and validation goals. Compare production-intent tooling with prototype or bridge alternatives before committing. The economic route depends on your design and program life.

What is the lead time for my tooling and parts?

Your schedule depends on DFM approval, tooling complexity, sample corrections, finish and inspection scope. Request a milestone plan separating tool build, T1 samples, approval and production delivery.

Who owns my mold, and how are changes handled?

Confirm ownership, storage, maintenance, transfer conditions and any tool-life terms in your quotation or tooling agreement. Approve the cost and timing of design revisions before work begins.

How do you address porosity or leak-tightness?

Review geometry, alloy, gating and process requirements early. Specify test media, pressure, duration and allowable leakage. Agree testing and any permitted secondary treatments before approving samples.

Can you machine and finish die cast parts?

Yes—review your critical bores, threads and mating surfaces alongside your coating or plating requirements. Finish compatibility, masking and coating thickness should be confirmed for your alloy.

Can I request FAI, PPAP and material documentation?

Include your required report format, inspection characteristics and documentation level with your RFQ. Scope and availability are confirmed for your project before production.
