Green sand moulding is a traditional and widely used foundry process that forms the backbone of metal casting operations. It involves the creation of moulds using a mixture of silica sand, water, and a clay binder, giving it a greenish hue and earning its name. When compacted around a pattern, the green sand mixture retains its shape and allows ...The preparation of green sand begins after the shake out machine once the separation of the casting sand and the sand is fed to the forming machines at the end of the process. Our green sand equipment includes control systems, moisture control systems, bentonite control systems and foundry automation systems.Green Sand - JML IndustrieTo minimize the initial green sand investment, standard molding machines offer a major advantage because a foundry can mechanize for green sand molding with reasonable initial expense, and the balance of the mold handing can be built over time. These machines can be the small 212/214 jolt machines, up through the 722 & 730 jolt molding machines.Green Sand Molding | EMI White Paper Series Issue 1احصل على السعر
