Articles made of Extruded rubber
products can be easily found in every car or home. Whether it is a seal or
be it a belt, extruded rubber products show distinct characteristics which
makes it suitable for applications involving appliance, construction or
automotive to aerospace, lighting electronics etc.
Basically Rubber Extrusion Industry is concerned with the manufacturing of
rubber extruded profiles. Rubber extrusion industry extrudes items like
sponge or solid tubing, rods, gaskets, cord, seals or other designs
according to specifications. The process involves forcing of rubber
continuously through a die. This results in formation of a desired
cross-sectional size and shape before the all important curing takes place.
The rubber extrusion industry has gone for a paradigm shift with latest and
highly advanced equipment for a faster and more reliable extrusion. The
following diagram shows a typical Rubber extrusion line.
Key Developments in the Rubber Extrusion Industry

Extrusion Industry: On-line
profile measurement system
The on-line measurement system featured here is extremely useful in
Rubber extrusion industry owing to an extremely short economic payback.
This machine achieves 100% dimensional verification of parts.
This on-line profile measurement system employs Bytewise Profile
Sensors for scanning total outside shape of continuously moving
profiles. This machine takes a profile scan, then matches it to a design
template, and displays an optical comparator screen along with the key
measurement parameters. This machines are applied on extruder lines as
an uninterrupted quality checking tool for ensuring key dimensions
remain centered and within tolerable limits.
