Innovative product design with high-tech compounds

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.


Innovative designs are often based on the physical properties of materials.

Construction materials at HECHT + DIEPER.

Due to their physical specifications, new, high-performance thermoplastics are the basis for products with previously unknown characteristics or with properties that were previously attributed more to metal. In metal substitution, they are increasingly displacing parts made of zinc die casting or aluminum due to their strength and stiffness at lower weight.

Low warpage, high dimensional stability, temperature resistance at high continuous service temperatures with simultaneous high mechanical stress are arguments for the use of plastics in the manufacture of technical components, for example in vehicle construction.

High-tech-compounds at HECHT + DIEPER.

In addition, many high-tech compounds are resistant to many chemicals, mineral oils and fuels.

Sliding properties are specifically improved by adding carbon fibers. Additives can be used to influence thermal and electrical conductivity in order to prevent static charging or to dissipate heat.

Thermochromic effects can be achieved with the aid of special additives: Plastics change color by changing temperature and can thus be used as indicators of certain conditions. Bio-thermoplastics are increasingly being used in plastic injection molding. The materials obtained from renewable raw materials are similar to petroleum-based compounds in terms of their use and processing properties and help to improve the eco-balance.
