Venus rubbers is a provider of engineering services and industrial rubber rollers to the Printing, Steel plant, Metal processing, Plastics, Paper , Textile industries, food processing ,office automation equipment (dot matrix printer / photo copiers).
Performance of a rubber roll depends on the rigid construction, minimal roll deflection and balancing of the roll shell. The pipe is usually, mild steel, cast iron, aluminium, Plastic in pipe or solid form. Steel or alloy steel is predominantly used on end shafts or journals and flanges. Welding, press or shrink fitting method is used depending on the working condition of the roll.
Grooving on the metal shell, degreasing, grit blasting /linishing are done on shells to ensure good bonding. Repair services of rolls include - journal welding and new bearing fitment ,Static and Dynamic roll balancing services available.
High quality compounds in Nitrile , Natural rubber, Neoprene, Hypalon, EPDM and specialty compounds like High release Silicone and Nitrile PVC are available. Rolls are coated by two methods - automatic strip building and calendared sheet. Rubber covering capacities up to 1500 mm in diameter and 7000 mm long. Vulcanising is done on SCADA controller autoclaves.
The paper industry rolls are primarily used in the dewatering, sizing, drying and calendaring processes. A wide range of rubber rollers, in a full range of hardness, are used to meet chemical resistance, high temperatures, coefficient of friction and abrasion resistance requirements of the paper making process.
The textile industry utilizes rubber rollers in a range of hardness (45A – 100A) designed to squeeze water and or chemicals out of substrate/fabrics that are being manufactured. Common elastomers used are Nitrile, Natural rubber, EPDM, CSM, XNBR, and HNBR
High performance roll for Thermal laminating machine offers excellent heat resistance and release. Rolls are manufactured in HNBR, Silicone and heat resistant nitrile polymers.
Major problems of printing industry rollers are hardening and shrinking of rollers in service – to address these problems, the compounds used should be chemical resistant with less heat buildup and hardness stability. Common elastomers used are Nitrile - PVC, Nitrile, EPDM and silicone.
