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.


Precision in tool and mold making is the prerequisite for high-quality plastic injection molding.

Tolerances derived from the shape and size of the plastic product as well as the material properties are taken into account in mold making to ensure the desired properties of the plastic component. Therefore, we always manufacture our molds in close cooperation with our development department at our premises.

The production of the molds is computer-aided.

The 3D data from the design are the basis for the CNC programs for milling and eroding the electrodes for mold making. With the aid of spark erosion (graphite technology), very fine contours and complex geometries are achieved with very short throughput times. All contouring inserts are hardened and ground.


Complex tool shapes through graphite technology

Spark erosion

Only graphite electrodes are used in our mold production. In contrast to conventional copper electrodes, they enable the erosion of much finer and more complex geometries. Fewer electrodes are required and milling processes are significantly accelerated.

The benefits of collaboration with HECHT + DIEPER

HECHT + DIEPER is your expert in injection moulding of plastics.



During development, our customers benefit from our many years of expert knowledge, in the area of design, our own toolmaking, as well as our competence in production.



Together - as specialists, we know that only the joint development of components is the best prerequisite for the optimal functionality of your product.



Since more than over 40 years we have been developing and producing technically challenging components of the highest precision for various industries.



In order to be able to deliver quickly, we believe in long standing and reliable cooperation with local logistics partners.



Regular optimization in development, toolmaking and production is a continuous process for us and thus the foundation for high efficiency and customer satisfaction.



Everything is local. We develop and produce plastic components - from the idea to production - one-stop. Our service enables short communication channels.
