Case Study Bearing Cage 0.028 gram shot

The Plastechnik AG, which is based in 3178 Bösingen, Switzerland, is specialized in the production of technically sophisticated plastic parts and the design and manufacturing of injection moulds. HEITEC Heisskanaltechnik GmbH in 35099 Burgwald, Germany, is known for providing special solutions in the area of hot runner technology, particularly in lateral injection and the production of highly specialized small nozzles.

Plastechnik AG approached HEITEC with an inquiry regarding the application of an extremely small shot weight, via HEITEC’s Swiss representative Mr. Daniel Jenny of the company E. Ramseier Werkzeugnormalien AG in 8602 Wangen, Switzerland

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 possible Heitec 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

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.
