Mold Design & Tooling
Mold design, DFM and mold flow analysis before a single steel block is cut — so the tool is decided on the drawing, not rebuilt after the first shot.
Four checks before steel is cut
- 01
Parting line and gate position
A cosmetic surface loses to a late gate change. Both are fixed on the drawing before any steel is cut.
- 02
Cooling layout
Circuit pitch and distance to the cavity decide cycle time and where sink marks appear.
- 03
Shrinkage and warpage
Resin grade sets the shrink allowance; the part's flatness requirement decides whether a fixture is needed.
- 04
Ejection and slides
Undercuts are resolved as sliders or lifter blocks at design stage, not improvised during fitting.
The grade follows the resin, not the budget alone
- P20 / 718HGeneral housings and large covers where polish is moderate
- NAK80Visible surfaces that need a fine, even texture
- S136Corrosive or medical-grade resins, and clear parts
- H13High-volume tools where wear of the gate area dominates
Insert layout, hardness and polish level are confirmed with the drawing review, so a corrosive resin does not force a polish-out later.
Design and tooling stay with one team: the drawing that clears DFM is the drawing that gets machined

Handed over with the tool on request
Send the part drawing and the target resin. A DFM note and a tooling scope come back on the same thread — no separate design house in between.
