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.


About us

HECHT + DIEPER is the high-performance manufacturer of plastic parts using injection molding. Since 1979, HECHT + DIEPER has been developing and producing technically sophisticated components of the highest precision for various industries: Automotive, electrical engineering, electronics, pneumatics, hydraulics, water technology, fittings, hardware and construction technology.

In the development of innovative solutions, our customers benefit from our knowledge of what is technically feasible, as well as from our state-of-the-art design and production. In particular, we demonstrate potential for innovative product development using multi-component injection molding, through the substitution of metals, with the help of metal-plastic combinations or through the use of high-tech thermoplastics with novel physical properties.


As innovative and technologically leading specialists in plastics processing, we know that the joint development of components is the best prerequisite for the optimal functionality and efficient manufacture of your product. Software-supported pre-testing of function and resilience and rapid prototyping enable short development phases with low risk. Quality assurance in development, tooling and production is a constantly accompanying process for us and the basis for high customer satisfaction.

Our company headquarters are located in Lindlar between the major industrial centers of Rhine-Main and Ruhr in the heart of Europe. Short distances and on-site construction are of inestimable advantage in the development of sophisticated solutions

We are here for you
