Ningbo Yinzhou Ke Ming Machinery Manufacturing Co., Ltd. is a leading supplier of investment castings with water glass process in China. The company specializes in the manufacturing of lost wax investment castings and finished products in carbon steel and low alloy steel. With over 10 years of experience in the industry, Ke Ming Machinery has gained a reputation for providing high-quality investment castings and excellent customer service.

Investment casting is a manufacturing process that involves pouring molten metal into a mold, which is then allowed to cool and solidify. The mold is typically made of wax or a similar material, which is melted away after the metal has solidified. This process produces high-quality castings with complex shapes and intricate details that are difficult to achieve with other casting methods.

Ke Ming Machinery uses the water glass process for their investment castings, which is a type of ceramic shell process. This process involves dipping a wax pattern into a slurry made of water glass and silica sand. The slurry is then allowed to dry and harden, creating a ceramic shell around the pattern. The shell is then heated in a furnace to melt the wax out of the shell and cure the ceramic material. Molten metal is then poured into the shell, and after the metal has solidified, the ceramic shell is broken away to reveal the finished casting.

One of the advantages of the water glass process is that it produces castings with a smooth surface finish and precise dimensions. This process also allows for the production of multiple castings from a single mold, which can save time and reduce costs. Ke Ming Machinery has invested in state-of-the-art equipment and technology to ensure that their investment castings meet the highest quality standards.
