Casting Draft Angle Guide: When Designers Need to Add Draft
Use this casting draft angle guide to review mold release, parting line, cast surfaces, machined faces, bosses, ribs, drawing notes and DFM risk.
Read Waking guides on custom metal casting, process selection, CNC machining, DFM, quality inspection, surface finishing and RFQ preparation.

Use this casting draft angle guide to review mold release, parting line, cast surfaces, machined faces, bosses, ribs, drawing notes and DFM risk.

Define machined surface roughness on castings by separating as-cast areas, Ra values, sealing faces, cosmetic zones, tool marks and inspection.

Use gravity casting for aluminum parts when geometry, wall thickness, tooling budget, medium volume, heat treatment, machining and inspection needs fit.

Choose a pipe fitting casting supplier by checking material grade, pressure boundary, threads, sealing faces, machining, inspection and certificates.

Review low pressure casting porosity by checking gas, shrinkage, melt control, degassing, filling, cooling, X-ray, leak testing and buyer acceptance rules.

Review stainless steel valve body casting by checking material, ports, wall thickness, sealing faces, machining, leak risk, inspection and certificates.

Define CMM inspection for machined castings by setting datums, CTQ dimensions, sample size, report format, casting variation and acceptance rules.

Improve casting wall thickness design by reviewing uniform sections, transitions, ribs, bosses, hot spots, shrinkage, machining stock and DFM notes.

Use sand blasting for castings by defining cleaning, surface profile, coating prep, visual acceptance, masking, defects and post-blast inspection.

Understand gravity casting tooling cost by checking mold size, cores, parting line, alloy, sample approval, machining fixtures, volume and inspection.
