The Space hot runner system from Heitec combines the benefits of valve gate technology with the advantages of side gating, making it possible to edge gate articles or multi-edge gate (e. g. from two sides) for the manufacturing of precision components in the medical and optical industries.

With a minimum cavity spacing of only 9 mm, this system is particularly useful with small tubes or also with thin-walled, long cartridges where the gate location reveals special rheological characteristics.

The hydraulic cylinder is positioned outside the mold so that heat effects on the unit are negligible and the installation of a digital position marker is possible. The drive unit is equipped with a central lubrication, which is maintenance free since there are no components such as O-rings that can wear out. It’s fitted needle retainers and the small tolerance between the diagonal gears results in almost no play. The main drive can be operated hydraulically, pneumatically or electrically.

Flow optimized melt channels and gate locations provide a large, low-shear plastic throughput along with superior gate vestige quality. The homogenous temperature profile of the Space system allows processing of nearly all resins regardless of being natural or modified with filler and additive materials.

The Space system is also externally heated with 230V.
