HECHT + DIEPER is a tech­nologically leading com­pany in the injection moul­ding of plastics tech­nology. It has many years of engineering experience and by using the latest tech­nologies reaching from development, mould con­struction, to tool pro­duction and manufacture HECHT + DIEPER is able to manufacture innovative plastic products of the highest precision.

The development and production of plastic parts – reaching from conceptualisation to production takes place under one roof: A prerequisite for short development phases and high product quality.


We use high-tech materials to replace metals such as aluminum, zinc (die casting) and brass.

Modern high-performance plastics have excellent physical properties. In many cases, metal parts can be replaced by cheaper, lighter and higher-performance plastic components with the same strength. We use high-tech materials to replace metals such as aluminum, zinc (die casting) and brass.


Greater design freedom with more functionality

In addition to lower material and manufacturing costs, designing components from plastic injection molding offers greater design freedom with more functionality, such as snap-fit connections or threads that can be formed like gauges.

Plastic components often have better surface quality for visible parts and are corrosion resistant without post-treatments such as anodizing, coating and painting. They have excellent dimensional accuracy and are easy to assemble into assemblies without additional machining.
