Rubber Mould, Rollers

We are the leading manufacturer of Raffia Machine Rubber Rollers, With the new metal cores in hand, the rollers are cleaned and coated with a bonding agent and are manufactured by molding, wrapping or extruding rubber onto the metal. Using heat and pressure vulcanization cures the rubber, and bonds the rubber to the core. In the case of conveyor rollers many times a permanent bond is not desired so a rubber sleeve is made slightly undersized from the core diameter so the sleeve can be pneumatically slid over the core for a tight, non-slip fit. Cynoacrylate bonding of rubber and metal after curing is also available and particularly useful for segmented rollers, this includes secondary operations to assemble. For plastic cores, rubber sleeves are made and either blown onto the core or glued.
