                • READY-TO-INSTALL

                  We supply ready-to-use ejection technology!
                  Whether cylindrical or shouldered round ejectors, flat ejectors, punches or ejector sleeves: On request, we adapt the ejector technology to the requirements of your tool. Your internal time input is reduced to a minimum by delivery of ready-to-use ejectors.

                    • EJECTORS WITH MOUNTING DIMENSION

                    • The DUOSCHLIFF cutting machine allows shortening of workpieces and then grinding to the desired length in one operation. With appropriate dexterity and experience our “cut-to-length specialists” achieve an accuracy of +/- 0.01mm.

                    • CONTOUR MACHINING

                    • We make your contour to ours and produce completely according to your data. Ejectors are shortened, locked and milled to specified tolerances. Depending on the field of application or requirements, we optionally offer a DLC coating.

                    • MARKING

                    • State-of-the-art laser control allows high-precision engraving. Even delicate structures and markings can be incorporated. Almost all materials can be provided with a durable, water- and smudge-resistant label.

                  • Plates with machining

                        • INDIVIDUALLY FOR EACH TOOL

                        • Regardless of whether it is a single work piece or a complete mould base: We provide finished plates completely customized according to your specifications!

                          • Machining of plates up to 1 500 x 2 000 x 500 mm
                          • Workpiece weight up to max. 5 000 kg

                    • Drives for stack moulds

                        • Helical gear

                        • The innovative solution when it comes to stack moulds. A special spindle geometry enables significantly higher load transfers. At the same time, minimum space is required on the tool due to an even more compact design. The use of handling robots or an additional injection unit is therefore not a problem. Thus, the spiral gear (462000) is not only a worthwhile option for high-speed moulds.

                          • Very compact design
                          • Special spindle geometry allows high load transfer
                          • Small space requirement on the tool
                          • Pre-assembled units allow easy and quick mounting
                          • Suitable for high-speed tools
                          • Flexible adaption possible (cut-to- desired length service)

                        • Rack gear

                        • The classic rack gear (461000), which comes as a pre-assembled unit, can be mounted quickly and easily on the tool. Depending on the mould size, two or four of these drives are installed. A closed housing offers additional stability. The well-known, but optimized design offers more than 30% space savings compared to similar drives.

                          • Very compact design
                          • Pre-assembled units allow easy and quick mounting
                          • Cost-efficient system solution
                          • Cut-to-size to desired length
