Mapa GmbH, a multicomponent injection molder in Zeven, Germany, has added a Krauss-Maffei molding and assembly cell to make a disposable baby bottle that has a thermoplastic elastomer nipple integrated with the screw-on top.
Mapa is molding the product in a Class 100 clean room — a smaller room inside a Class 10,000 clean room. Air to the Class 100 area comes only from the Class 10,000 room.
Krauss-Maffei Kunststofftechnik GmbH of Munich, Germany, supplied the injection press and a parts-removal robot. The nippled-lid parts are made and packaged without any operator intervention.
Traditionally, the nipples were molded of latex rubber and the polypropylene screw-on ring was added after molding. Each part had to be disinfected and packaged. By using multicomponent molding and packaging, all inside a clean room, Mapa can skip the disinfection step.
The U.S. headquarters, Krauss-Maffei Corp., is in Florence, Ky.
