Heitec Heisskanaltechnik Specially designed nozzles optimise processes in small moulds
Germany – Heitec has expanded its product line to include a special design of the Flat-Line nozzle series.
The patented Flat-Line nozzles are said to enable the injection of articles with the smallest cavity spacing using separately controlled nozzles.
Thus, the nozzles are frequently used when there is a shortage of space in the mould and in the production of electronic products, such as reel-to-reel applications, strip over-moulding and similar applications, the company says.
According to Heitec, the new design enables a location very close to the article. Due to its low mass, heat transfer into the mould is minor, and the temperature of the cavity is only affected minimally. Also, space can be gained in the mould by utilising this nozzle to allow more room for functional components close to the injection point such as ejectors or slides or often, space for mould-cooling.
The nozzle is supported on three points due to its design, reminiscent of a “T”, the company explains.. It is also used in the medical industry, where it offers advantages in the direct gating of syringe barrels.
