The main selection of high-quality coated sand natural quartz sand as raw sand, thermoplastic phenolic resin, methenamine and enhancer for raw materials. According to the needs of different users coated sand regeneration techniques in curing speed, stripping, mobility, collapsibility, the casting surface finish, storage, etc. properly adjusted to match. Is one of the cars, tractors, hydraulic parts and other materials the best shape. Making entity core theory, coated sand can produce almost all types of coated sand regeneration, especially high-precision casting core entity. When using the wet coated sand coated sand reclamation line manufacturers, direct access to hot-box core making equipment and tooling without the original equipment and tooling to make any changes. When using dry coated sand, because of its mobility, the need for core box exhaust system, nozzle and core box seals for special treatment. Angle of repose principle can be used (coated sand repose angle of about 30o), coated sand into the sand shot resolved when the exhaust chamber and shoot do not shoot automatically when the sand coated sand whereabouts and other issues. Currently, the use of dry heat coated sand box core technology manufacturers are more high-quality selection of coated sand major natural quartz sand as raw sand, thermoplastic phenolic resin, methenamine and enhancer for raw materials. Depending on the technology needs of users, the curing speed, stripping, mobility, collapsibility, the casting surface finish, storage and other aspects of appropriate adjustments to match. Is one of the cars, tractors, hydraulic parts and other materials the best shape.
