Production of plastic and rubber punched parts

Punching is a non-machining cutting process. The material is severed in this process. Tools that exactly correspond to the desired shape and size of the punched parts are used for processing. During the punching process, the material is clamped between two tools and severed by a punch that moves down to a counterpart called the die. The edges of the die and punch are absolutely parallel to each other. At the start of the punching process, the material is deformed by the contact with the punch before it is cut and finally breaks due to the high tension forces at the cutting contour.Punching is a non-machining cutting process.

Materials in use

Various materials can be used for the production of plastic punched parts. The most common materials range from rubber to plastics. We mainly use cellular polyethylene, cellular rubber, foam rubber, NR/SBR, silicone, butyl, HPDE and EPDM/SBR as well as CR in production. Other materials required by you can also be used on request. In combination with various processes and manufacturing operations for the production of punched parts, we offer a broad portfolio. Realising highly complex assemblies is possible thanks to different joining technologies. We therefore offer you complex solutions for all your rubber and plastic punched parts.

Benefits of producing rubber punched parts

The benefits of punching are extensive. First among these is the ability to offer a variety of contours and transformations of the plastic and rubber punched parts. Since there are no thermal influences on the material, the quality remains consistent even at large quantities. This leads to the additional benefits of economical and flexible production.

Leading applications

In addition to the usual feedstock, we also work with foamed materials to produce a wide variety of rubber and plastic punched parts. These parts can be used for many different purposes, for example rattle and vibration prevention but also for sealing, damping, insulating, as spacers and in numerous other applications.

Sample applications:

· Rattle prevention
· Vibration protection
· Sealing· Damping
· Padding
· Spacers
· Covers
· Insulation
