HECHT + DIEPER is a high-performance manufacturer of plastic parts in injection moulding. Since 1979 HECHT + DIEPER has been developing and producing technologically sophisticated high-precision parts for an array of industries: Automotive, electrical technology, electronics, pneumatics, hydraulics, hydro engineering, fittings, locks and construction technology.

In the development of innovative solutions our customers will benefit from our know-how regarding the technically feasible and from our construction and production, which uses the latest technologies. In particular we would like to show you our potential for innovative product development using multiple-component injection moulding, the substitution of metals using metal-plastic composites or high-tech thermoplastics with new physical properties.


As innovative and technologically leading specialists in the field of plastics processing we know that the joint development of components is the best prerequisite for optimal functional performance and efficient production of your product. Software aided pretesting of functions and load capacity and rapid prototyping allow for short development phases at a low risk. Quality assurance is a continuous accompanying process in development, tool design and production and is the fundamental basis for high customer satisfaction.

Our company seat is in Lindlar, which is between the large industrial centres of Rhein-Main and the Ruhr Area in the heart of Europe. Accessibility and the construction on site are of immense advantage in the development of sophisticated solutions.
