For many engineers, injection molding simulation of plastics is still relatively unfamiliar territory, as engineering efforts often focus more on metals than on polymer materials. At our training center, we provide in-depth knowledge of injection molding, its special processes, and the underlying material science. Our goal is to enable engineers to confidently master the simulation of this often perceived complex field. To achieve this, we have developed practical training courses that offer significant added value, especially for professionals involved in part and component development.

🔵 High-temperature resistant variant of the MH series ⚪ The products of the MH-FHD series are particularly suitable for use in engineering plastics and in all areas requiring particularly high processing temperatures. 🔵 Advantages: • Temperature resistant up to 300 °C • Widely compatible • Narrow, controlled particle size distribution • Excellent flow and dispersing properties • Food-grade approval 🔵 Applications: Masterbatches and compounds: • Antiblocking in foils and films • Light scattering in PC, PS, and silicone 🔵 Available particle sizes: 3 µm, 4 µm, 5 µm

The Michel Vario-Wand was derived from the Michel Vario-Tisch. ‍ The Michel Vario-Wand combines the advantages of the Michel Vario-Tisch with even greater on-site installation flexibility. The components are delivered individually as an assembly. The panel is hung / mounted like a picture and also serves as a cover plate. Add-on parts such as a collecting tray for granules and/or codings can also be retrofitted. ‍ The Michel Vario-Wand can be installed horizontally, vertically and at an angle. Cutting to size is possible on site. This enables the fitter to set up a coupling point on site in the simplest way.

More and more injection moulding companies are facing the challenge that the ratio between the large installation dimensions of their moulds does not match the small injection volumes of the cavities. In these cases, the user has to resort to a large injection moulding machine with an oversized injection unit. Thermally damaged plastic and inaccurate control of the non-return valve are frequent results. Groche Technik has developed the GTM unit for these applications. With the GTM unit, the required injection volume is plasticised in an injection chamber with a reduced cross-section and injected using a specially developed piston screwtip. This allows the volume to be reduced by approx. 30%. In order to achieve an even shorter residence time, Groche Technik can carry out geometry modifications for the barrel and screw. Depending on the type and application, the plastic volume in the barrel can be reduced by up to 50%. A reduction in injection force is required before the GTM unit is commissioned. + Volume reduction of approx 30% possible + Mass cushion is formed in the injection chamber + Reduction in residence time + Lower thermal load on the material + Compatible with almost any injection moulding machine + Usually no need to use microgranulate

A small LSR system that attaches directly to the mold. No expensive LSR machine is required for this.

Our Stereo-Dynascope microscopes allow us to process even the smallest surfaces at 40x magnification. This helps prevent edge damage, especially with minimal parting lines.

We mill complex components for you up to a size of 1600x 1600x 1400mm, using high-precision 3- and 5-axis as well as HSC technologies.
