About PLEIGER Kunststoff
PLEIGER Kunststoff, based in Witten, manufactures technical precision parts from plastics, in particular from polyurethane materials such as Vulkollan and the proprietary PLEI-TECH systems. The product and service portfolio includes injection-molded components made from engineering thermoplastics with an individual weight of up to about 1500 g, compression-molded parts, wheels, rollers and tires for conveyor technology, as well as components for coupling, damping and spring technology. Production is carried out to drawing or sample; along the value chain, the company offers design, formulation development, tool and mold making as well as production and distribution from a single source. In addition, PLEI-TECH 3D provides additive manufacturing for prototypes, small series and heat-resistant casting molds. Founded in 1925 as a machine factory, the company is today part of a globally operating group with production on three continents, supplying industries ranging from conveyor technology and agricultural and municipal technology to pump and process engineering.
