Innovative solutions across injection molding

For more than 50 years we are at home in the world of plastics and here we bring a multidisciplinary applied and practical knowledge. Whether mechanical stress at transport containers, large numbers of closures, light weight construction at automotive, clean room applications with small wall thicknesses in medicineā€¦
In the field of Hot Runners our solutions convince daily and worldwide by reducing of cycle times, rapid color changes, dimensional stability, gating to reach shortest closing times, little cavity distancesā€¦

New: The revolutionary pipe concept pipeLine

Unbelievable but true: 80% less pipes and a much higher stability of the tool. In conventional systems each operating unit must be connected with four pipes, two for hydraulic and two for the cooling. This makes at a 8drop system already 32 pipes!
The required space for the pipes must be cut out of the mold plate. This means an extra effort and thereby reduces the tool stability.
The new pipeLine from PSG connects the operating units only with two pipes. A pressure line and a return line! The hydraulic oil moves the pin and cooles the operating unit at the same time.  Water cooling with associated calcification is superfluous.

Services and know-how beyond the Hot Runner

It is not all about the nozzle or the Hot Runner, it is about your project success. Injection molding is a very complex theme. Therefore we look ahead that your application will meet the specifications. To round it all up, we offer you a complete program of Hot Runner Controllers as well as Control- and Tempering-Systems. PSG offers you solutions from one source and guarantees, that all components coordinate. This simplifies your project setup, shortens start-up time, and provides advantages during maintenance. 
The main branch focuses on are automobile, medicine, packaging and transport - last but not least the know-how transfer. It is normal procedure to share PSG solutions and technology to other sectors, i. e. long fiber processing, which is normal in the automobile industry.

The customer service challenges we face, help us provide better service

New plastics for hybrid solutions, long fiber applications to improve the stability, Molded-in Color solutions for reduction of costs, faster color change, MIM, WID, GIT ... these are challenges for our development team which likes to come up with individual solutions. It would be in your best interest to contact us at the start. We are looking forward to your innovative challenges!

We offer our experience from more than 100 different costumer solutions (Coreback, Index-plate method, conversion method, rotation tool, ...). Shear-rate optimized melt channels ensure less pressure loss during TPE/TPO processing. When combining TPO with technical plastics PSG utilizes thermally insulated manifolds and enables short cycle times.
