Salt Tanks
ESI offers conveyorized, cascade or submersion salt tanks for vulcanization of rubber compounds. The recommended conveyance method depends on the characteristics of the extrudate. Conveyorized tanks are recommended for delicate profiles, which will stretch if pulled from downstream, such as wiper blade elements. A stainless steel conveyor belt is mounted within the salt tank to carry the extrudate down-line, under the belt, with minimum pulling tension, driven on two large grooved steel pulley rolls (one at each end). Conveyor belt tensioning is automatically controlled within each tank by means of an air cylinder, which compensates ...
Hot water wash tank
ESI's hot water wash tanks are used to remove excess salt from salt cured rubber profiles. Because the salt solidifies immediately when touched with cold-water, hot water sprayed with special high velocity nozzles is used. Tanks can be supplied in various lengths and with one or more zones. Multiple zone hot water washes are fitted with a cascading water system so that the cleanest water is used in the downstream section and the salt concentration increases in each zone closer to the salt tank. Special electric heaters, mounted to the exterior of the reservoir are utilized to avoid heater failure due to salt buildup.
IR Heating Channel
ESI's IR heating channel can be used for pre-heating of rubber and plastic profiles and hoses. These ovens feature high heating efficiency, digital temperature control, clam-shell opening for easy string-up and tubular steel frames. Entry and exit guide rollers are fitted. Various lengths and heating capacities can be supplied and external IR temperature sensing and control, multi-zone temperature control and heater cutoff options to avoid fires are available.
