Metal Replacement

Our portfolio for metal replacement is one of the broadest in the world

Using plastics instead of metal saves cost and effort. These cost savings already begin with the manufacture of the molded parts. Die casting alloys require melting temperatures of 400 to up to 600°C. High-performance polyamides are generally processed at temperatures lower than 340° requiring significantly less energy. 

Using plastics instead of metal saves weight and energy

The potential weight reduction of the molded parts is as high as 75%, an essential factor in improving ultimate energy efficiency, especially in the automotive and transportation areas. The shortening of work processes is an additional advantage. Finishing work on the molded parts can usually be completely eliminated.

Mold diversity and design freedom are guaranteed

Additionally, plastics offer more design freedom. In the conventional metal die casting processes, components with a wall thickness of approximately 0.9 mm and greater are produced. By contrast, the use of high-performance polyamides make very thin wall thicknesses possible. Wall thicknesses to be filled of only 0.2 mm are not unusual anymore. With the alternative use of plastics instead of metal, corrosion resistance, too, has become a non-issue, along with sustainability and recyclability.

Metal replacement means highest requirements for plastics

An intensive examination of the requirement profiles and product properties is always the first step for the right product choice. Plastics that are suitable for metal replacement are, above all, characterized by two essential properties: high strength and stiffness. The dominant materials used here are polyamides, closely followed by polyesters (PBT/PET). To achieve the described properties, a high reinforment material content must be relied on. This is primarily achieved by a glass fiber filling content of more than 50%.

From engineering to high-performance plastics – we have the ideal solution for your requirement!

The ultimate service temperature of the work piece is an important criterium for the choice of materials, too. We differentiate here between two material categories: materials that are suitable for applications in the service temperature range of up to 150°C and those that are used in the high temperature range. PA 6 , PA 66 , PBT and PET are especially suitable as raw materials for the first category. For higher service temperatures, high-performance products such as PA 4.6 and PPA are desirable. The temperature gap between these groups can be bridged with specially modified PA 66.
Our experts and product developers who specialize in metal replacement will be happy to advise you in detail on choice of product, processing and possibilities.
