Hot runner systems for single-use medical products
 
 
The production of engineered plastic parts for the medical industry requires quality and process reliability as well as high output rates. This calls for hot runner technologies with individually controlled nozzles for close cavity spacing, systems with direct edge gating and clean room suitable actuations for valve gate systems. The interaction of these individual components gives engineers a focus on energy efficiency.

5.5mm Flat Nozzle

5.5mm flatlineTechnoject Machinery Corp. (Bolton, ON) offers a HEITEC hot runner nozzle that allows a cavity spacing from only 5.5 mm, resulting in maximum production efficiency. With its small installation dimensions it no longer hinders or interferes with any cavity detail. It was further developed from the Flat-line Series, which has been established in the market for more than 10 years as flat nozzles with a sealing diameter of 6 mm and a min. required distance from 7 mm.
