DFM & ENGINEERING SUPPORT
Die Casting DFM — Designed for Sound, Repeatable Castings
Die casting molds run at 200–300 °C against molten alloy at 600 °C+, so fill, cooling and steel selection are decided before a single cut. Our engineers review every part for gateability, draft, wall balance and porosity risk before quoting.
Die Casting Mold DFM Analysis
Wall Thickness & Draft
0.8–1.5 mm thin walls for aluminum, down to 0.5 mm for zinc — with draft angles verified for clean ejection and minimal distortion.
Gating, Runner & Overflow Design
Balanced fill profile, overflow and venting layout to control porosity — validated in trial castings before delivery.
Cooling & Thermal Simulation
Conformal cooling channels where geometry allows, keeping die temperature stable for controlled solidification and cycle time.
Shrinkage & Tolerance Prediction
Alloy-specific shrink rates (0.5–0.7% for aluminum, 1.0–1.2% for zinc) compensated in the CAD model before machining.
Our 6-Step Die Casting Mold Workflow
Part and Gating Study
Gating, runner and overflow design for sound castings.
Die Design
3D design with cooling simulation and steel selection.
Machining
Gantry CNC, wire EDM and precision grinding of cavities.
Heat Treatment
Hardening to hot-work specifications with records.
Assembly
Slide, core and ejector assembly by senior toolmakers.
Trial and Delivery
Trial casting, sample approval and dimensional report.
