Efficient manufacturing in injection moulding of plastics

Contact us

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.


From technical miniature components to finished articles of daily use.

Our production is designed for the production of plastic parts from 0.05 g (almost micro injection molding) to approx. 500 g. The production spectrum of possible plastic parts thus ranges from technical miniature components with the highest demands on fitting accuracy to finished articles of daily use for the consumer goods industry.

HECHT + DIEPER plastic injection moulding machine park consists of ARBURG injection moulding machines with a clamping force of 205kN - 3,000kN and offers the flexibility for both high-volume production and small series. With ARBURG 2K injection moulding technology with clamping forces of up to 4,000kN, HECHT + DIEPER can simultaneously combine different materials in one product in a form-fitting and force-fitting manner (two-component or multi-component injection moulding).

Highest efficiency in production is our goal.

With fully automated production for feeding inserts, unloading and palletizing of finished plastic parts, HECHT + DIEPER ensures cost-optimized production under high quality standards.

Deliveries are made throughout Germany and Europe.
