From early on it became clear to Josef that few companies had plastic molding expertise comparable to Janler, so he started contract manufacturing plastic parts as well. By continually investing in new technology, Josef kept Janler at the forefront of the design, development and manufacturing of critical tolerance plastic injection molds in addition to plastic injection molding.
