Head of Development, Electrical engineering company - industrial connectors and electromobility

At Delvac Sanitär GmbH, in cooperation with the plastic injection moulding firm Reico, we can look back on more than 25 years of cooperation with Otto Injection Molding. Together, we have been able to make use of our experiences, capitalising on them to develop new products. The latest project is a hand shower, which is already on the market. The development of this shower was supported by Otto through preliminary work in the creation of 3D data and tool data. The individual parts, such as control ring, faceplate and soft-clean rubber plate, were developed together.
