Die Casting Design Guide summary

A practical DFM checklist for walls, draft, ribs, fillets, holes, bosses and machining allowance.

Use this guide as a preparation checklist before sending an RFQ. Final decisions should still be based on the controlled drawing, application requirement and project evidence.

Wall thickness and transitions
Draft and parting line
Ribs and bosses
Machining stock and datum strategy

02 / Use

How to use this guide

At the start of a project, list the assumptions that affect tooling, casting, machining, finishing and inspection.

Then mark which items are confirmed by the drawing and which still need engineering review.

Confirm the drawing revision
Identify critical features
Define material and finish
State annual quantity and delivery target
List required inspection documents

Buyer questions

Questions to resolve before production.

These answers define the normal project path and the information needed for a useful quotation.

What information is needed for a die casting design guide review?

Provide the controlled 2D/3D drawing, material requirement, annual quantity, finishing requirement, critical dimensions, target market and delivery date.

Can the project start from a sample or concept?

An initial feasibility discussion is possible, but the quotation and tooling scope should be based on a controlled drawing revision.

How are tolerances set?

Tolerance and inspection requirements are defined from the drawing, critical features, process capability and agreed datum strategy.

How is tooling ownership handled?

Ownership, storage, maintenance and transfer terms are defined in the quotation or supply agreement before the tooling project starts.

Continue through the project path.

Use the internal links to connect the material, process, industry, product and RFQ pages around one project decision.

Send the drawing. Get the engineering questions first.

Include the material, annual quantity, finishing requirement, target market and delivery date. The review can start from STEP, IGS, DWG, DXF, PDF or ZIP files.
