EXTRUSION , HOT VULCANISING AND FABRICATION
Particular attention to detail plays a vital role in the manufacture of extruded
sections and profiles, with various applications demanding different tolerance control.
SEP takes a keen interest in the intended use of products to ensure that they are always
suitable in terms of dimensional stability, hardness colour matching where required, and
that the most reliable rubber is used.
An almost infinite range of sections can be produced in most grades of rubber i.e. food
grades (FDA), high and low temperature capabilities and compounds resistant to known
medium.
Whilst most rubbers can be joined using a comprehensive range of modern adhesives, the
most successful method of joining two pieces of cured rubber together permanently is by
hot vulcanising. This process can offer virtual equivalence in strength, flexibility and
resistance to product or atmospheric attack and maintain the clean lines of an endless
moulded product.
This process is normally utilised for manufacturing products that are impractical to
mould in one piece, offering significant savings in tool charges with quicker
deliveries.
Virtually any shape, hardness or rubber type can be joined.
