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 user needs different techniques resin sand recycling machine, 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. Other special requirements to meet the needs of resin-coated sand sand recycling equipment for different products, developed a series of special coated sand as: centrifugal casting coated sand, chilling coated sand, wet coated sand, sand sticking anti veins, anti-cellulite coated sand. While in 2004 the newly introduced fast-curing coated sand on the basis of the performance has the cure rate can increase 30-70% resin sand reclamation equipment, improve production efficiency and energy saving easy collapsibility coated sand with a more class good strength, but also has excellent low temperature performance collapsing, for the production of non-ferrous castings. The thermal method centrifugal casting process in metal type (iron type) in the conventional centrifugal casting process rough shape, mainly for the production of Tube rotator casting, first in the iron mold cavity surface coated layer of paint in order to facilitate hanging modulo . In recent years, has developed a suitable alternative coating production centrifugal casting coated sand. Because of its exhaust is less effective, it requires a thin wall (about 3mm), and often using double sand, and casting the contact surface with sand (70/140 mesh), the outer layer of coarse sand (50/100 mesh) resin sand recycling machine _ Qingdao Heng (certified) _ resin sand regeneration provided by Heng Machinery Co., Ltd.
