China cast steel ball Manufacturer, Supplier, Factory

Cast steel balls are wear-resistant grinding media manufactured via high-temperature metal mold casting and professional tempering heat treatment. We supply full series including low chrome, medium chrome and high chrome cast steel balls with diameter ranging from 10mm to 150mm. The product features uniform internal hardness, ultra-low breakage rate, outstanding abrasion resistance and stable roundness without deformation during long-term grinding. High chrome cast steel balls reach HRC 56–62 hardness, medium chrome HRC 47–55 and low chrome HRC 45–52, perfectly matching dry and semi-dry ball mill working conditions. Widely applied in cement plants, mineral processing mines, thermal power stations and chemical grinding workshops. As a direct Chinese manufacturer, we support bulk tonnage supply, customized chrome content & sizes, and provide complete ISO certification and material test reports to global industrial buyers with competitive factory prices.

Our mullite sand is a premium alumina-silica refractory material produced by sintering or electric melting. Featuring high refractoriness, low thermal expansion, superior thermal shock resistance and stable chemical performance, it is widely used for shell making in investment casting and precision casting. Available in multiple grades and particle sizes, our products effectively prevent sand sticking, reduce casting defects and simplify shakeout process, ideal for aerospace, automotive and general industrial casting applications.

Jar Hing is the manufacturer and supplier of Double-Station Four-Column Type 28T Wax Injection Machine. Our machine is specially designed for investment casting. The double-station design doubles the efficiency directly. The four-column structure also ensures the stability and accuracy of this machine during operation. The clamping force of 28 tons can make the wax material filled more evenly and densely, eliminating bubbles and defects. Therefore, whether it is to produce complex aviation blade wax molds, or delicate medical device parts, this machine can handle them easily.

Jar Hing has its own factory, which can design and produce 800mm Floating Sand Machine Back Layer, which is the key equipment to protect wax mold during investment casting process. It is responsible for uniformly adhering the back sand layer on the surface of wax mold to form a strong mold shell, so that the precision and quality of castings can be guaranteed when pouring molten metal later.

Jar Hing is a specialist manufacturer and supplier of plastic case machines, and our 800mm Low Noise Convenient Maintenance Slurry Dipping Machine is one of these machines, offering low noise operation, easy maintenance, high efficiency for industrial applications, and a size of 800 mm that provides sufficient capacity for slurry impregnation.
