VARIO cold runner system causes amazement with variably adjustable nozzle distances
|
A great surprise to the complete industry was the brand-new-developed and patent pending VARIO cold runner system. The first cold runner which allows to easily adjust nozzle positions and thus to adapt to most various moulds.
On the showcased model the nozzle distances could be continuously adjusted from 240 mm to 460 mm and this without changing balancing!
The VARIO cold runner system can be delivered with a varying number of nozzles and with a customized designed adjusting range.
Here the main advantage is that this cold runner can be used for complete groups of moulds and thus its usage is quickly refinanced because of the material savings even in case of small quantities per mould. Especially as far as the seal production and in particular the article arrangement is concerned, one is no longer tied to fixed nozzle positions that often entailed compromises concerning the maximally possible number of cavities. The adjustment of the nozzle position is made from outside by means of a socket wrench. Each nozzle can be adjusted individually which is additionally advantageous for the production of large seals with several injection gates.
The different nozzle positions in the adjusting range are either totally flexibly adjustable or, if requested, indexed. As an alternative, all possible positions can be pictured through a template enabling an easy and fast changing of the nozzle position. After adjusting the nozzle, it only needs to be secured from outside against being twisted. This is realized by means of a locking screw. The exact function of the cold runner system is visualized in detail on the virtual show booth. More »
