In aluminum casting operations, the efficiency of ingot demolding directly impacts productivity, product quality, and operational costs. Draft angles and surface finish are two critical design parameters that determine how smoothly solidified aluminum releases from sow mold and ingot mold cavities. Proper attention to these specifications prevents casting defects, reduces mold damage, and extends equipment service life. Understanding the relationship between mold geometry, surface characteristics, and metal release mechanisms enables aluminum producers to optimize their casting processes and achieve superior results in both primary aluminum production and secondary recycling operations. How Draft Angles Facilitate Smooth Aluminum Ingot Ejection? Draft angles represent the slight taper built into mold walls that allows cast aluminum ingots to release without resistance or damage. In sow moulds and ingot molds, this seemingly minor geometric feature plays a decisive role in demolding su

Every day, aluminum foundries face a critical decision that directly impacts their bottom line: how to handle hot dross efficiently. Without a dross press machine, foundries unknowingly accept substantial financial losses that accumulate into significant yearly deficits. The absence of proper aluminum dross recovery equipment translates into lost metal value, increased waste disposal costs, and missed opportunities for maximizing aluminum recovery yields from every batch processed. Direct Aluminum Loss Without Dross Press Machine When primary or secondary aluminum plants skim dross from molten aluminum, the hot skimmed material contains considerable recoverable aluminum metal encapsulated in a matrix of aluminum oxide, salts, and other by-products. Without a hot dross press machine, this valuable metal is simply discarded or sent directly to landfills. The liquid aluminum embedded in white dross represents immediate monetary loss that could otherwise be squeezed out and returned to th
