An Auto Spray Unit is an essential automation component in die casting machines, designed to spray a controlled amount of die lubricant onto the mold cavity before each casting cycle. This ensures smooth metal flow, prevents sticking, and enhances the lifespan of the mold by reducing thermal stress and wear. The auto spray unit operates with precision-controlled nozzles that evenly distribute the lubricant, ensuring consistent coating and minimal waste. Integrated with programmable settings, it can adjust the spray duration, pressure, and coverage area for optimal performance. Used in hot chamber, cold chamber, and gravity die casting processes, the auto spray unit improves casting quality, reduces cycle times, enhances surface finish, and minimizes defects like porosity and cracks. Its automation reduces manual intervention, increasing efficiency and ensuring high repeatability in automotive, aerospace, and industrial casting applications.
