If so, larger valve gates or "hot sprue gate
"-type tips are recommended.
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.
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
. This provides a more cosmetic gate vestige and eliminates labor costs associated with removal of remaining sprue.
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.
