We supply tailored, special parts manufactured with our state-of-the-art cold-moulding and extrusion equipment. We can press cold-moulded articles – whether solid, semi-hollow or hollow – according to your drawings. Complex moulded parts and individual, special projects are our strengths. Our cold-moulding competence covers flanged bolts, studded parts, stepped bores and parts with an internal or external thread. Possible materials: Regular steel, stainless steel, brass, copper, light metals. Available with all standard surfaces.

Service Cleaning: Our customers count on our contract cleaning team for their daily cleaning needs -. With modern cleaning processes e.g. thermal with pyrolysis, aqueous with ultrasonic or mechanical with lapping blasting we can clean and improve your high quality tools. Whether extrusion or injection molding tools, extruder screws, hot runners, nozzles, filters, molds, screens, adhesive or coating devices - everything will be cleaned by us for you! Detailed advice and documented cleaning of samples ensure consistent results over a long period of time. Test us - In addition to comprehensive advice, we offer you the opportunity to carry out your own cleaning trials of workpieces up to a length of 3 m and / or 4 t in weight. Cleaning trials: Every customer can convince himself of our offer by a free sample cleaning.

WIWOX® CORUS HD ultrasonic systems have been specially designed for cleaning high-quality moulds and precision tools. In maintenance these replace the labour-intensive and often ineffective manual cleaning. The ultrasonic cleaning process can be used for all metal moulds, in particular tools for injection moulding, extrusion, rubber processing as well as aluminium and gravity die casting. A typical structure consists of three stages: 1. cleaning, 2. rinsing and 3. passivating. The usable dimensions are matched to common mould sizes. The workpieces to be washed are placed in the tank either with the aid of a washing basket or with a lifting beam. Our ErgoStation is recommended for manual rinsing, drying and post-treatment. The working area is completely enclosed, brightly illuminated and ventilated. Operation is safe and simple, as the moulded parts are loaded laterally through a sliding door and held by a lifting device during treatment.

PolyPlus® LD 1925 ZZ is a versatile, stabilized, and extremely effective purge compound on an LDPE basis specially developed to reduce the cleaning times of extrusion and injection molding plants to a minimum. It should be used before dismantling and cleaning the extruder, during planned and unforeseen extruder downtimes and during material and colour changes. PolyPlus® LD 1925 ZZ contains surfactants and abrasive agents with mechanical and chemical cleaning properties to remove degraded polymer and pigments from the extruder and from the die. The use of PolyPlus® LD 1925 ZZ immediately before the cleaning process has shown that downtimes can be reduced my more than 50%! This also applies for product and/or colour changes.
