12 Cav Star-Line Crown

HEITEC Star-Line Crown 12-Cav

HEITEC introduces a new version of the 12-Cav Star-Line Crown 01.072.64.12.140 based on the proven Star-Line hot runner nozzles. This multiple nozzle for side gating of plastic articles can inject up to 12 cavities using a single hot runner nozzle. This results in a significant reduction of the control requirement since you only need one control zone to control the temperature of 12 mold cavities.

The new design allows even greater output per mold area and thus ultimately much smaller tool dimensions. The smallest possibleHeitec Star-Line Crown 12 freigestellt fit diameter is 64mm. Hence, up to twelve injection points can now be placed on a circle of about 76mm instead of eight as in the past.

As with the other types of the new generation Star-Line nozzles the length expansion of the nozzle does not matter anymore in terms of possible "wandering" injection points as the growth in length is completely compensated inside the nozzle by the two-piece structure of the nozzle body.

The nozzle is characterized by a very good thermal profile. It provides a completely particle free production as well as no strings, which makes it attractive for use in clean room production.

Heitec recommends the nozzle for the production of complex plastic articles from standard resins.

Also in terms of energy demand the 12 Cav offers large potential savings over other hot runner nozzles.

Of course, the new design also comes with all the other benefits of the Star-Line Crown Series.

Machined Manifold Melt Channels

color flowchannel 1Machined Manifold Melt Channels

Heitec offers a solution to dead spots in the melt channels of hot-runner manifolds.  The melt channels are milled into the plates, providing a smooth channel for the plastic to flow through.  This eliminates any sharp turns or any hang up points (dead spots) in the manifold.

Hot Runner System for Medical Micro Parts

Hot Runner System for Medical Micro Parts

 

In response to the demands for ever more compact hot runner systems for the production of plastic components used in the medical and electronics industry Heitec Hot Runner Systems introduces new hot tip designs. Heitec Heißkanaltechnik GmbH from Burgwald, Germany is represented in North America bymicro1 Technoject Machinery Corp.

Until 2011 a 6.0 mm cavity spacing was considered to be the smallest possible using individually controllable hot tip nozzles. Continuous development of the Flat-Line nozzle series now allow a distance from 4.5 mm. This sets new standards for space utilization and maximum number of cavities per mold.

New Valve Gate System with a minimum 5.8mm Gate spacing

New Valve Gate System with a minimum 5.8mm Gate spacing

 

A new valve gate hot runner system with miniature space requirements was developed by Heitec Heißkanaltechnik GmbH from Burgwald, Germany represented in North America by Technoject Machinery Corp.valve-gate-nozzles-5.8

Based on the already existing Flat-Line Nozzle platform 61.041 the new nozzle design achieves a minimum nozzle spacing of less than 6 mm. With this design a complete valve gate system with e.g. 4, 8, 16 or more nozzles can be arranged in very small mold base sizes resulting in lower mold costs, higher productivity, more design flexibility and less melt residence time.
