HOFFMANN GMBH GUMMI- UND KUNSTSTOFF-FORMTECHNIK

SHORTENED CHANGEOVER PROCESS In modern production processes, factors such as efficiency and flexibility play an increasingly important role. For injection moulding companies, this demand for flexibility means there is a constant challenge posed by increasingly smaller lot sizes, the desire to achieve lower inventories and just-in-time deliveries.

In the area of elastomer technology, the Zimmer Group uses the most modern production processes to manufacture sophisticated workpieces from elastomers. In addition to the transfer molding process, in which the elastomer is placed in a mold, pressed into shape with a die and vulcanized under pressure and heat, we also use the injection transfer molding process. Here, the starting materials are pressed into the mold on an injection molding machine and vulcanize out there. With these two processes, we process a wide range of elastomers such as NBR, silicone, EPDM, FPM or polyurethane. In terms of quantities as well as dimensions, the sky's the limit, because we can manufacture almost any quantity required, from special solutions in quantities of one to medium-sized small batches and large series of more than 10,000 units.

THE BENEFITS OF TWO WORLDS Series components made of metal with complex shapes are usually very time-consuming and expensive to put into production -- but luckily there is now a superior alternative for these kinds of demanding workpieces in the form of MIM technology from Zimmer Group! The MIM process allows us to manufacture metal parts of almost any shape using an injection molding process, as easily as though it were plastic! This process lets us elegantly combine the geometrical freedom of plastic injection molding with the outstanding rigidity and wear characteristics of metals. The result is a thoroughly impressive technology for manufacturing metallic series production components with complex shapes -- and at very attractive prices, too!

When it comes to sophisticated plastic injection molding, we are completely in our element. We process all common thermoplastics, from standard to high-performance plastics. A fully automated production with handling systems for part removal and QA tests guarantees an economic production of your parts. We also have experience with the overmolding of various inserts such as threaded bushings, electronic contacts, circuit boards and much more. This and much more are the reasons why we are a reliable partner for almost all industries: Automotive industry aerospace industry Mechanical engineering Medical technology Construction industry Electrical engineering Jewelry and watch industry Furniture industry
