Swiss precision engineering combined with over 40 years experience provides you with the best shut-off system on the market today. Quality, dedication and service are why we are the world's No. 1 manufacturer and supplier of needle and bolt shut-off nozzles for the injection molding industry.

 
Machine shut-off nozzles for packaging applications

Herzog’s needle and bolt shut-offs are today’s most efficient and effective nozzles for packaging applications. Whether you are producing caps and closures, thin wall parts, light weight or large containers Herzog’s innovative solutions provide stability to your process.



The single channel design ensures maximum throughput in order to lower cycle times. For example with thin wall applications, highest injection pressure and performance can be used to support minimal wall thickness. Only Herzog has an integrated actuation solution that supports injection rates of up to 5,000cm3/s. This also reduces your overall footprint for retrofits and options exist for machine side actuation which makes an even more compact solution.

Full control over opening and closing ensures shot consistency which helps improve part quality and lowers reject rates. Process reliability can be improved by using integrated sensor options which relay the open and closed state of the nozzle.

For weight reduction specially modified nozzle options with precise shut-off control offer support for physical and chemical foaming applications.
