Resin coated ceramic sand

Short Description:

Sintered ceramic sand is an artificial spherical casting sand developed by SHXK. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (30% reduction in binder content), and particles high strength, non-breaking and other characteristics, suitable for sand casting (molding sand, core sand), coated sand, V method casting, lost foam casting (filled sand), foundry coating (ceramic sand powder), 3D printing and other casting processes. It is green and environmentally friendly foundry sand.

Sintered ceramic sand is an artificial spherical casting sand developed by SHXK. It has high refractoriness (>1800°C), small angular coefficient (<1.1, approximately spherical), low acid consumption (neutral material), low binder content (30% reduction in binder content), and particles high strength, non-breaking and other characteristics, suitable for sand casting (molding sand, core sand), coated sand, V method casting, lost foam casting (filled sand), foundry coating (ceramic sand powder), 3D printing and other casting processes. It is green and environmentally friendly foundry sand.

Part of the ceramic sand is used in the molding sand and core sand to make the shell mold and shell core have the properties of high temperature resistance, low expansion, easy collapse, and low gas output, which can effectively prevent expansion defects in castings. For cores with particularly complex shapes, can deal with the problem that sand shooting is not easy to compact.

Full ceramic sand is used to make coated sand, and reused repeatedly after reclamation, which can effectively improve the quality and production efficiency of castings, reduce the castings scrape rate and the production cost of enterprises, the long-term use cost is lower than that of silica sand. Therefore, in recent years, almost all large-scale coated sand plants have used ceramic sand as raw sand to produce coated sand.

Advantage

● Resin coated ceramic sand with super high temperature resistance, strong resistance to deformation intensity, low inflation, low gas evolution, to meet the special requirements of customers.

● Good fluidity filling ability, non-stick mold, applicable for the artificial core-making process.

● Super high temperature resistance could avoid to casting defects such as sand burning, surface fold, veining, joint flash and crack.

Application

Engine cylinder block, cylinder head, piston ring, oil seal, floor spring.

Small and medium-sized stainless steel, steel casting shell, off-core.

Used in large turbine shell mold, 6-8 speed gearbox, main part of auto brake disc.

Muti-cylinder block(empty flip type core), the exhaust pipe and bronchus.

Camshaft, oil seal, container corner shell.

All kinds of high standard, high requirement, difficult process of coated sand castings.
