Localized Mold Temperature Control Optimizes Surface Quality

Incoe Corp. features dynamic localized mold temperature control with its Heat-INject technology to demonstrate how the part surface quality and the filling of the cavity is optimized with relatively little effort using targeted heat pulses. 
When parts are unitized with the hot runner, heat pulses are transferred into the cavity wall to avoid the knit line where the melt flows merge. Heat-INject technology offers a solution for reducing knit lines about holes and openings on a part.

Additionally, the technology is said to improve melt flow through cold runner fan gates or part thin wall sections of the cavity. Heat-INject technology is designed as an add-on module to Incoe unitized manifold systems, offering a simple design and implementation, reduced mold modifications/costs compared to other solutions and low power consumption — only 220VAC/30-amp power input is required.

Heat-INject technology localized selection of dynamic mold temperature control ensures significantly improved part quality and low-stress filling of the cavity. Incoe’s multi-use Flight Attendant parts have three holes and demonstrate the Heat-INject technology solution.
