Stamped parts & blanks

Customized solutions for the industry

Stamped parts and blanks made of rubber, plastic or composite materials are indispensable components in industrial production and applications. Their applications range from seals and underlays to wipers and dirt traps. These parts are usually manufactured by mechanically processing semi-finished products using modern technologies such as punching machines, water jet cutting systems or plotters. Rubber flat gaskets in particular are characterized by their ability to compensate for gaps on surfaces that come into contact with each other, thus ensuring a secure seal against internal and external media.

Application areas

Precise adaptation to specific requirements

The correct choice of material is crucial for the efficiency of stamped parts and blanks, especially in the field of sealing technology. Precise adaptation to the chemical and physical operating conditions is essential to ensure the reliability and functionality of the parts. Errors in material selection can lead to seal failure and thus damage to the entire system.

Versatility thanks to porous materials

In addition to solid materials, porous materials such as cellular rubber, sponge rubber, polyurethane and silicone foam offer additional application possibilities. Depending on the manufacturing process and raw material composition, these foams can be produced with different cell structures, which significantly influences their properties and areas of application.

Surface treatment

The possibility of specific surface treatment opens up further customization options for stamped parts and blanks. The range of applications for these components can be further optimized using individual or standardized processes.

Refinement

In addition, various finishing techniques enhance the functional and aesthetic properties of the parts, thus increasing their value and variety of applications:

Single or multiple fabric inserts with different qualities
Lamination of films
Lamination of adhesive systems
Stamping of multi-layer pull-off tabs
Printing
Takeover of assembly scopes

Guidelines and standards

Manufacturing tolerances: DIN ISO 7715
FDA guidelines
Food and Feed Code
Regulations of the Federal Institute for Risk Assessment (BFR) for food contact materials and articles
DIN 53428 - Testing of foams - Determination of behavior against liquids, vapors, gases and solids
