Manhole Cover Products Production Line

This plant is used to produce sheet molding compound (smc) which is new type thermosetting molding plastics. This kind plastic are widely used in automotive industry, rail vehicles, construction, electrical, communication engineering, catering appliances, sports equipment etc. This unit produces smc sheet by forming sandwich structure which outside are two layer films and polyester resin, fiber glass, release agent, hardening agent in the middle. There are four parts: host, take-up part, cutting part and electrical control part. The host uses frequency conversion motor. Materials are compacted by belt chains which are controlled by pneumatic form. The belt chains are made of stainless steel. Take-up part adopts torque motor-driven and take-up speed can be adjusted at any time. Cutting part uses variable speed motor. The cutting roller is helical. This can increase working life of the rubber roller and blade. If high fiberglass content is required, such as above 30%, we can design double cutting roller on this machine. Also we can design machine according customer’s special requirements.
