At K 2016, October 19-26, in Dusseldorf, Germany, Ewikon will display hot runner solutions for multi-tip gating and valve gating, with a focus on compact multi-cavity applications.

The company’s new micro-manifold technology is designed for large-scale production of polyolefine parts in molds with an extremely large number of cavities. In the packaging and medical industries, this technology has already been successfully used in molds with as many as 192 cavities, the company says. The balanced micro-manifolds feature four screwed-in, heat-conductive tip inserts each, which have a flow channel diameter of 3 mm and a melt seal directly at the gate. A fully balanced flow channel layout is then achieved by placing a main manifold on a second level.

Four gates only require one heating circuit, reducing the cost for control technology, as well as the number of cables and therefore the amount of space in the manifold frame plate needed for wiring of the system.

The company offers complete hot halves with micro-manifold technology as 16-, 32-, 64-, 96-, 128- and 192-drop versions with standardized dimensions.
