Extrusion profiles and hoses are produced using a specific design die or required cross section. Different types of extruder head capacities allow us to offer a wide range of sizes and profiles in hundreds of shapes and designs, according to customer requirements.
Extrusion production lines:
By producing the product in a closed mold, we have the flexibility to adapt quickly to manufacture a broad range of precisely molded products with excellent dimension control and consistency. The quicker time cycles enable us to produce an array of custom shapes with less rubber waste.
By controlling the weight, dimension and position of the charged compound, we are able to combine the rubber with metal or plastic and reinforced textile materials, all in different sizes and shapes.
Continuous vulcanization technologies:
The goal: To produce a compound (and product) with uniform dispersion and distribution of the “ingredients”
The mixing and compounding process includes the following steps:
Extrusion Silicon profiles are produced using a specific design die or required cross section. Different types of extruder head capacities allow us to offer a wide range of sizes and profiles in hundreds of shapes and designs, according to customer requirements.
# Silicone profiles & tubes in different design (hardness, color)
# Solid and sponge profiles (peroxide or platinum curing system)
# Non-flammable profiles according to norm EN 45545-2 (HL1, HL2, R23, R24)
# Profiles in transparent colour for the contact with food (FDA grade)
# Maximum profile size 70x100mm
# Extrusion line COLMEC – the best silicon line producer in the world
Variety of Applications of silicone sealing & gaskets in all market segments such as: doors, windows, facades or constructions (for extremely high isolation – high/ low temperature), industrial automatic doors, trains, profiles for food industry, profiles for closed swimming pools & pergolas, sanitary facilities seals and many more.
This production process relates to the actual design of the reinforced fabric. We use a special press to create the specific shape of the fabric that fits perfectly with our shape-molded diaphragms.
The fully cured extruded profile is bonded to any required size gasket by high-quality volcanized joints for superior tensile strength and large serial production. This technology adapts well with different materials (EPDM, SBR, NBR, Neoprene and others).
Our sponge profiles (in different shapes and sizes) are extruded from designed died and cured in microwave, hot channels or salt bath. We have the ability to do a single die extrusion, co-extrusion and triple extrusion from 0.4 g/cc to 0.8 g/cc.
The process involves applying special short fibers of Nylon/Rayon directly on the profile that has been coated with adhesive. This technology perform a dual function: sealing and easy movement.
We have the technology to apply the self-adhesive on any product profile or molded part for sealing purposes. This technology is applicable for different lengths, shapes and materials, per the application requirements for bonding and mounting.
This type of co-extrusion production technology combines metal with rubber through the use of exceptionally strong gluing of the metal and the rubber. Rubber gives the flexibility; metal provides the stability.
