New Product Release - Water Cooled Gate Insert


Troy, MI USA -
Water Cooled Gate Insert. One of the essential factors for the injection process is uniform temperature profile in an injection mold. This has a direct and basic influence on the cycle-time and the quality of the molding.

Using a hot runner system results in an elevated temperature in the gate area of the mold. Heat at processing temperature is transmitted over the contact areas from the hot runner into the mold. In general, temperature difference between hot runner and mold is approximately 200°C. If the gate area is not sufficiently cooled, defects and surface quality problems will result. Altering the cycle to attempt remedy yields negative economical conditions or increased rejects.

Elevated temperature may also cause valve gate pins to stick to the molded part. The pin is only in contact with the mold during cooling time and ejection of the molding. During this period of time, it does transfer temperature to the mold allowing cool down. During the injection phase the pin is inside the flow channel surrounded by hot plastic material. In these cases, intensive cooling of the gate is located as close as possible to parting line. Up to now, such cooling could only be realized with complex gate inserts, which are complicated to install into the mold. The patented cooling insert, developed by INCOE®, combines optimal cooling of the gate with minimum effort for the mold maker. The cooling medium passes through the very front areas of the gate insert and effects turbulent flow thus effecting optimal cooling. The boring details accommodate simple mold installation.
