Today's consumers expect more, so should you. MHS is a trusted partner for appliance manufacturers around the globe because of our unparalleled project support and innovative and systematic approach to improved quality and reduced cost. Whether you are looking to make stronger parts with less material, more functional or exotic parts with multi-material injection or consolidate production through stack molding and family molding, we have the solutions that will help you succeed.   

Flexible Melt Channels
The Rheo-Pro® Slide™ Manifold is a revolutionary new type of hot runner system with rotating melt transfer joints that allows linked manifold segments to move freely in order to distribute plastic anywhere inside the injection mold. The new technology now makes it possible to create injection points, or gates, directly inside the moving slides of a mold. It also allows molders to create continuous melt transfer connections that maintain contact, and therefore flow, even when the mold plates separate.

94 drop hinged manifold system for extremely large, lightweight PP part with a thin wall thickness of 1.0 mm and valve gates in the moving mold slides on 4 side walls. The hot runner features 12 Slide™ joint elements (hinges) that allow the mold to 'open and close' during each cycle.
