Jolt failure is a common fault of automatic molding machines, mainly caused by three factors. First, blockage of air filter elements. Water vapor generated during vacuum pump operation mixes with pipeline impurities and clogs filter cartridges. The pressure gauge displays normal pressure, yet insuff

Low temperatures easily worsen fluidity of hydraulic oil and cause water freezing in pipelines of fully automatic horizontal molding machines, triggering hydraulic jamming, pipeline rupture and cylinder malfunction. Proper winter anti-freezing maintenance is critical to guarantee stable equipment operation through cold seasons.

Molding sand performance directly affects sand molding effect and serves as the core to control casting defects such as sand adhesion, blowholes and sand eyes. To stabilize casting quality, systematic control of various molding sand indicators must be implemented.
