Hot Runner Valve Pin Velocity Control

INCOE® Corporation introduced the SoftGate® hot runner valve pin velocity control, which resolves process challenges related to conventional hydraulic sequential molding. Poor flow characteristics leading to part inconsistency, flow hesitation lines, or blemish marks are reduced with SoftGate®. The gradual pin actuation, precisely timed as needed for optimized melt flow velocity to the mold cavity, provides a key process control advantage for molders.

The SoftGate® technology approach precisely operates the hydraulic valve pin actuation at varying intervals to ensure exact, repeatable filling; part after part. The technology consists of a control module in the hydraulic unit and a velocity calibration unit. Combined, the molder now can have improved part appearance and structure with the ability to record the Valve-Gate pin metering that produces the best melt delivery results. SoftGate® also offers simplified and effective operation and ease of maintenance.

For added value, the technology has been designed to retrofit onto existing INCOE® hydraulic valve gate systems, allowing molders to take advantage of SoftGate® without the requirement of purchasing a completely new system.
