Germany invents two-component injection molding technology

The German company Kraff Maffei announced in the forecast of the K2004 (Düsseldorf Industrial Rubber Industry Expo 2004) that the company will exhibit the KM 160 with PU (polyurethane) mixing and metering devices at the exhibition. 750CX injection molding machine.

It is reported that the KM 160-750 CX injection molding machine was the first equipment to successfully combine injection molding and reaction technology for thermoplastic and PU two-component injection molding. This process called Skinform has successfully prepared a luxury car seat belt buckle, the structure of PU casting nylon preforms. Characteristic of having excellent surface quality, the general multi-component injection molding thermoplastic elastomer technology cannot achieve such high quality.

According to Walter Tesche, head of technology management at Kraff Maffei, due to the low viscosity of the PU, special molds are required to suit the requirements of the processing PU. The thickness of the PU is 0.8 to 3.0 mm, but the company will not show the skinform process at the show. The specific structure of the PU will not reveal whether it is a microporous structure or other cell structure.
