ation Compaction Table

The vibration compaction table is a core piece of equipment specially developed for modern foundry processes. By means of high-efficiency vibration, it achieves precise and dense compaction of molding sand. Using vibration motors for excitation combined with elastic damping technology, it effectively eliminates voids between sand particles, allowing the molding sand to fill the mold cavity uniformly and at high density. This significantly improves the strength and hardness of sand molds, preventing defects such as mold expansion, sand adhesion, and gas porosity during casting. As a result, it plays a key role in ensuring castVibring dimensional accuracy, surface quality, and internal integrity.
