CONVEYING PET planet Insider Vol. 18 No. 03/17 www.petpla.net 34 Energy-efficient technology improves productivity Variable conveyor speed for optimal material handling Bergmann Spritzguss und For- menbau GmbH & Co. KG, which is headquartered in Telgte-Westbevern in Germany, was founded in 1989. It is an injection moulding company and system supplier that supplies a large number of customers from a wide range of industries. Bergmann offers a compre- hensive range of services, ranging from the initial conception to the develop- ment and construction of plastic parts and relevant tools, as well as prototype construction, right up to the production process. The company’s portfolio also includes two areas of specialisation – Laser Radiation Welding and Direct Metal Laser Sintering – that are increas- ingly gaining in significance. Bergmann has two production sites. One in Telgte and, since 2000, one in Czaplinek, Poland. It currently owns 75 injection moulding machines with clamping forces of between 250 to 10,000kN, which include two 2-component machines, all equipped with parts removal devices. The company currently employs around 290 people. Each of the company’s production sites has a production area of around 10,000m² and is predomi- nantly used to produce technical parts as well as assembled components over three shifts a day. The parts it produces range from extremely small precision parts with a part weight of 0.5g to large products weigh- ing 5.8kg. The company processes around 4,000t of plastic annually, all of which are thermoplastics (with the exception of PVC). This means that Bergmann processes a wide range of different materials, which include 50 different types of material alone that require drying. On average, tools have to be changed five times a day. The company has 20 tool room staff who design and manufacture between 80 and 100 injection moulding tools with dead weights of up to eight tons for the company’s own production every year. Production expansion with central material supply system As the production facility in Telgte reached a stage where it could no longer cope with the increase in demand, Herbert Bergmann, founder and managing director of the com- pany, decided to invest and exten- sively expand the facility. The com- As part of expanding its production facilities, Bergmann Spritzguss und Formenbau GmbH & Co. KG, which is based in Telgte-Westbevern, Germany, decided on a radi- cal approach and equipped its entire production facility with a brand new material supply system comprising a central drying system, dosing systems and conveyors as well as a frequency-controlled conveyor control unit.
