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.

Numerous brands of fully automatic molding machines exist on the market with uneven equipment quality. Foundries shall not only focus on prices when purchasing equipment. Master five key points to select stable and cost-effective fully automatic molding machines.

Casting technology covers a complete system including casting structural design, gating systems, feeding systems and venting systems. As core equipment for sand molding, molding machines rely on air pressure or hydraulic pressure to drive squeeze mechanisms and complete compaction of molding sand.Ea
