Elastomer profiles

Customer-specific fabrication

Joining possibilities

Angst+Pfister offers a variety of fabrication processes that enable extruded profiles to be bonded to frames or rings. The processes depend on the material employed.
 

Self-adhesive backing

Profiles can be equipped with a self-adhesive backing, whether as an assembly aid or as a functional adhesive bond. For mass-produced profiles, self-adhesive stripping can be applied immediately after extrusion, or it can be applied afterwards by hand for small-series batches.
 

Mechanical processing

Mechanical processing encompasses subsequent cutting to length, drilling or notching of finished extruded fabricated elastomer profiles. Some of the mechanical processing work can also be executed immediately after extrusion.
 

Activatable AIRMATIC^® sealing systems

When it is impossible or not economical to mechanically press seals onto horizontally or vertically movable elements, the sealing function can be achieved reliably and efficiently by means of employing pneumatically activatable, self-retracting AIRMATIC^® sealing systems.

Profile labeling and surface treatments - the perfect finishing touch

Profile labeling

Logos, item numbers, manufacture dates, batch numbers, etc., can be printed on profiles either directly during extrusion or afterward by hand using a pad printing process.
 

Surface treatments

Surface treatments are applied to profiles for purposes such as to prevent them from sticking together, to facilitate installation, to reduce coefficients of friction or to enhance resistance to destructive influences.
 

Talcum powdering

Powdered talcum is applied to the profile surface. This prevents profiles from sticking together during storage and enhances ease of assembly and installation.
 

Siliconization

A silicone oil is applied to the profile surface. The sliding properties improved this way are advantageous mainly for reducing assembly and installation forces. The silicone oil dries over time and thus loses its properties.
 

Antifriction coating

Process similar to siliconization. Antifriction coating enhances ease of profile assembly and installation and improves the sliding properties in the application. In contrast to silicone oil, the antifriction coating retains its properties after it dries.
 

PTFE spray coating

Liquid PTFE is sprayed onto the profile surface and then sintered in an oven. The microporous layer reduces static friction and prevents the profiles from sticking to other materials. Severe dynamic strains erode the coating relatively quickly. The PTFE spraycoating process is relatively cost-intensive.
 

Flocking

Tiny monofilament fiber particles (called flock) are deposited on the surface of a profile first coated with an adhesive. Flocking enables profiles with very good long-term sliding properties to be manufactured. Flocking is a very cost-intensive process that requires mandatory minimum production volumes.
