Air leakage hazards of molding machines cannot be ignored. Workshops shall implement regular air leakage inspection and maintenance to eliminate leakage faults timely, stabilize production and cut overall operation losses.

# Multiple Hazards of Air Leakage on Molding Machines to Casting Production
Molding machines rely on compressed air to drive processes including vibration compaction, squeeze compaction, pattern stripping and flask closing. Air leakage in the pneumatic system triggers cascading losses in five dimens

The fully automatic molding machine is the core precision equipment of the casting production line. Due to its long-term high-speed cyclic operation, it is susceptible to wear, gas leakage, and jamming due to the influence of sand dust, high-pressure pneumatics, and mechanical vibrations. Regular maintenance is crucial for maintaining product quality, reducing fault rates, and extending the lifespan of the equipment. The workshop must implement standardized maintenance operations on a regular basis.
