Zinc-aluminum die casting is a kind of powder die casting parts with zinc as the main component. This kind of part is a very dense surface layer on the outside, and the inside is a dispersed porous structure. Acid degreaser cannot be used, but only alkaline degreaser can be used for degreasing.
In the manufacturing of zinc and aluminum components across automotive, electronics, and hardware sectors, a significant proportion of parts require application of copper-nickel-chromium multilayer coating systems to achieve both functional corrosion resistance and aesthetic surface quality that meets decorative standards.
Because the melting point of white wax exists at a temperature above 70 degrees Celsius, achieving effective emulsification of white wax requires maintaining the temperature of the wax removal water at levels exceeding 70 degrees Celsius throughout the process. In conventional manufacturing approaches used historically, operators relied exclusively on ordinary chemical degreasing solutions with elevated temperatures to accomplish wax removal from metal parts, a methodology that proved time-intensive and delivered comparatively lower efficiency rates in terms of processing throughput and quality outcomes. Contemporary specialized wax removal solutions have emerged in industrial supply chains to address these limitations, substantially reducing the overall processing duration while simultaneously improving the consistency and effectiveness of wax removal results across batch production. When ultrasonic technology is integrated into this wax removal process, the outcomes demonstrate particularly favorable results, enhancing the molecular-level disruption of wax bonds and accelerating the emulsification mechanism.
The composition of electrolytic degreaser formulated for zinc alloy processing shares fundamental similarities with conventional chemical degreaser formulations in terms of basic surfactant and alkaline components, though it requires substantially higher concentrations of complexing a
