Fully automatic molding machines run under high-frequency cyclic operation for long periods. Regular fault detection can eliminate hidden dangers in advance and reduce unexpected shutdowns. Troubleshooting focuses on two core modules: vibration compaction mechanisms and squeeze head mechanisms inclu

Flask closing is the final critical procedure of molding. Improper operation easily triggers casting defects such as metal leakage, flask misalignment, sand inclusions and flask lifting. Operators must complete item-by-item inspections.

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
