Transport industry – tramways

Seals for tramways

Tramways are a solution to counteract the increased traffic volume.

By means of our own compound development and production already nowadays we have components that meet the requirements regarding DIN ISO 45545 released by external certified test laboratories.

Increased requirements of our customers require a wide-range of possibilities regarding development.

Regarding your specific application we are ideally positioned: 

Our experienced team of product developers in combination with our possibilities regarding simulation together with our extensive possibilities concerning reinforcing supports, adhesives and sealing compounds or surface treatment systems is the basis to find also for your application an ideal solution. 

A coextrusion combining a soft sponge rubber area (sealing area) and a hard dense rubber area (fitting area) is state of the art for us, offering an excellent fitting and sealing function.

As reinforced materials we are using:

  • punch strips
  • stamped metal strips
  • wire reinforced strips

delivered in a flat performance by certified suppliers.  

Before we are able to use the reinforced materials for the extrusion we have to shape it to an U-form by means of special bending tools regarding the required dimension and shape. 

To keep the tooling costs as low as possible we check already during the calculation process id we can use an already existing bending unit or a similar bending unit. 

Surface refinements by means of our permanent and high grade slip-coating systems is intended to minimise the friction and as a freezing protection. 

If required our profiles can be coated online also with flock.

High grade EPDM-profiles enable a flexible application even in cases of high temperature variations  (-35° to + 120° C.).

Furthermore an assembly regarding frames or lengths including cut-outs or drilled holes is possible.
