Moldex3D Gate Wizard supports nine widely-used gate types, including pin gate, sprue gate, edge gate, fan gate, etc.
This technology enables the efficient production of high-quality parts in large numbers, without requiring the separation of a sprue gate.
It features standard and wear-resistant tips in three styles, including a sprue gate design that provides low flow resistance, a ring gate style with a sealed tip for efficient shutoff at the part surface, and a point gate design suitable for high-viscosity resins.
Puller pins and bushings are suited to three-plate molds to hold the sprue gate in place for proper orientation of the sprue and for runner removal.
Easy and Effective Mold Design Thenew mold module of ZW3D 2013 enables users to freely customize their designs, including sprue gates, runners, mold bases and other mold standard parts.
Gating methods include diverted hot tips, sprue gates, valve gates and edge gates.
Shutting off the gate eliminates the sprue that is typically found with thermal sprue gates.
Hot tips, sprue gates and edge gates all depend on a thermal slug or barrier of semi-molten plastic at the gate to allow clean degating of the part.
