Nozzles Overview

Hot Runner Systems

Exact solutions from 0.1 to 10,000 g shot weight

From the smallest nozzle "Nano" to the biggest nozzle "Big-Shot" we offer an extensive nozzle program with fitting manifolds.

Services and know how beyond the hot runner

It is not about the nozzle or the hot runner, it is all about your project success. Injection molding is a highly complex area. Therefore we look ahead, so that your application will fully meet the specifications. To round it all up, we offer you a complete program of hot runner controllers as well as temperature management and cooling systems. PSG offers you total solutions from one source and so assures you that all components are compatible. This simplifies your project planning, reduces start-up time, and provides advantages during maintenance.

Our industry focus is on the automotive, medical, packaging, and transport sectors, and last but not least, knowledge transfer. It is not uncommon that PSG solution technologies, such as long fiber processing, as it is common in the automotive sector, for example, can be applied to other sectors.

We grow with your challenges

New plastics for hybrid solutions, long fiber applications to improve stability, molded in color solutions for cost reduction, faster color change, MIM, WID, GIT these are the challenges for our development team who likes to come up with individual solutions. Best you already contact us during your planning phase. We are looking forward to your innovative challenges!

PSG Process Know How

Molded in Color

Molded in Colour

Reduce your cost by eliminating the base paint. PSG offers solutions to prevent black spots through shear-rate optimized melting channels. Special single connectors enable a quick color change.

Back Injection

Optimized temperature profile of the nozzle head prevents damages to the sensitive decorating fabric. Extremely slim nozzles enable insertion between the ejectors and save cost.

Long Glass Fiber Processing

Long fibers break considerably less.

PSG offers special-design melt diversions from the sprue bushing to the outlet opening of the nozzle. Part-quality improves noticeably

Tandem Tools

We integrate our hot runner systems precisely into your tandem process.

In-Mold-Labeling

We ensure a clean gating in the foil area through low heat exposure on the component.

Multi-Component Injection Molding

: Multi-Component Injection Molding

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.

Crystal clear plastic (PC, PMMA, PS...)

Crystal clear Plastics (PC, PMMA, PS...)

: Crystal clear Plastics (PC, PMMA, PS...)

The precise valve gate allows us to achieve a "perfect" injection point in the vision range.

MIM Metal Injection Molding

: watch, MIM Metal Injection Molding

We enable metals molding processes through diffusion-welded hot runner manifolds with specially tuned nozzles.

Cascade Injection Molding

Here we exactly match our controllable valve gate system with the suitable controller.

PSG Technologies

Hot Half

The extensive package for standard as well as for client-specific solutions.

Modular Structure

We increase component quality and production reliability through modular manifolds. This translates to lower stacks and additional support possibilities, hence, a more robust tool.

Precision Valve Gate Nozzles

PSG precision valve gates guarantee hardly visible injection points and a high reproducibility of the high-quality gate through a cylindrical fit and pre-centered needle guidings.

An ideal solution for limited space installation conditions is the Quattro nozzle.

Single Nozzles with Valve Gate

Only the Prima nozzle with an annular piston operating unit enables a direct component connection within the valve gate without manifold.

The ideal solution for prototypes.

Stack Mold Tool

PSG offers the Prima-series for back-to-back valve gates.

Cooled Ante-Chamber Bushings

Cycle time reduction through ante-chamber bushings with integrated cooling.

Electromagnetic Valve Gate

E-mag-S and E-mag-V: Lowest energy consumption, high energy transmission, shortest valve times, suitable for clean room, low wear-and-tear...

Front-sided Nozzle Installation / Dismantling

Service-friendliness is already shown during the construction of PSG products. Changing of heaters, sensors or gate inserts without dismantling the tool from the press. This saves time and costs.

Color Change

A constant challenge for our hot runner development is to optimize color change. Examples: melt-channel polishing, the new gate Mikro RC5, valve gate automotive molds (door covering)...
