4-Drop Hot Runner Valve Gate System Offers Compact Design

Heitec Heisskanaltechnik, based in Burgwald, Germany and distributed in North America by Technoject Machinery Corp. of Bolton, Ontario, offers a newly designed, compact valve gate hot runner system. In the past, mold designers have struggled to place gate locations close to the center of the mold due to limited space available for the valve pin actuation above the manifold block. The only available solution was to move the gate locations much farther away from the centre, resulting in unnecessarily large mold bases.

Heitec Hot Runner Systems, specializing in small component technology, addresses these space constraints with innovative solutions. For example, a 4-drop valve gate system can be arranged on a 30 mm bolt circle in the centre of the mold. This design makes it possible to easily install a mold into small tonnage machines such as a 7 or 10-ton.

Feature highlights include a compact valve gate system, 30 mm bolt circle for four gates, independant control zone for each drop, low hot half thickness for limited stackup heights, CAM actuation that ensures precise mechanical movement of the valve pins and optimized flow channel volume, good for small part weights.
