About GWK Pankoke
GWK Pankoke Kunststofftechnik specializes in thermal management in injection molding. The model for cavity-proximate temperature control of injection molds is the network of blood vessels: short thermal conduction paths and an even distribution of temperature control channels enable the correct mold wall temperature for every type of plastic. Based on the company's experience, a cavity-proximate cooling channel layout can reduce cycle time by an average of about 30 %, thereby lowering production costs. In addition, GWK implements segmented tool cooling, which allows critical areas in the mold to be controlled separately — this reduces the tendency to warpage through uniform shrinkage and prevents residual stresses in the plastic. An example product is the crossbar for a large household appliance made from the raw material PP TV20. The location and further company data are not provided on the website.
