Our products and applications 

Our closure nozzle solutions are specifically designed to enhance your production processes.

Through flow-optimized designs and cooled closure systems, we provide maximum process security and reduce cycle times through effective process overlap.

In addition to our proven needle and bolt closure nozzles, we offer a wide range of products to optimize the injection molding process. These include filtration systems, mixing units, gas injectors, and injection valves.
