Aluminum Die-Casting Process Minimizes Mold Sticking Problems

"Sticking" refers to the phenomenon in die casting where molten aluminum adheres to the surface of the mold. This issue significantly impacts productivity and quality in die casting. Main Causes of Sticking: 🔹 Uneven Temperature Distribution If the mold temperature is not properly controlled, molten aluminum is more likely to adhere abnormally to the mold surface. 🔹 Improper Use of Release Agents Insufficient or improper application of release agents can cause the product to stick to the mold, making removal difficult. 🔹 Substandard Mold Material and Surface Treatment If the mold surface is not properly treated, the friction between the aluminum and the mold increases, leading to sticking. Problems Caused by Sticking: ❌ Reduced Product Quality Surface defects on finished products can deteriorate performance, which is especially critical for automotive parts and electronic control components requiring high precision. ❌ Reduced Production Efficiency Frequent mold cleaning to remove adhered aluminum buildup slows down production. ❌ Reduced Mold Lifespan Adhered aluminum layers can damage the mold, increasing maintenance and replacement costs. Our Sticking Prevention Measures: ✅ Optimized Release Agent Selection & Application We select the appropriate mold release agent for each product, ensuring even spraying across the entire mold surface to prevent aluminum from sticking. ✅ Automated Spraying with Robots Using spray robots ensures uniform coating of release agents, effectively preventing sticking and surface defects. ✅ Strict Mold Temperature Control We apply advanced mold temperature control systems to maintain stable temperatures and prevent aluminum from sticking or causing dimensional deformations. ✅ Mold Surface Treatment with Special Coatings We use anti-stick coatings to reduce friction between aluminum and the mold, minimizing sticking. ✅ Continuous Process Improvement We regularly review our production processes to identify and eliminate factors contributing to sticking.

Aluminum Die Casting with Minimized Discoloration

"Discoloration" refers to changes in the surface color of a metal due to manufacturing processes or environmental factors. In aluminum die casting, discoloration can occur after casting, significantly impacting product quality and customer perception. This issue is particularly critical for products that require high aesthetic and surface finish standards. [Main Causes of Discoloration] Oxidation During Casting Aluminum is highly prone to oxidation. If the product surface comes into contact with oxygen during casting and cooling, an oxide layer forms, leading to color changes. Improper Use of Release Agents Release agents are essential for ensuring proper separation between the mold and the product. However, if the release agent contains incompatible chemical components, it can trigger undesirable reactions, causing discoloration. Cooling Process Issues Rapid or uneven cooling can alter the surface crystal structure, leading to color inconsistencies. [Yamaguchi’s Discoloration Control Solutions] Although discoloration is a major challenge in aluminum die casting, it can be effectively controlled through proper techniques and management. With years of expertise, Yamaguchi has developed a specialized manufacturing process that significantly minimizes discoloration, ensuring high-quality surface finishes that meet customer expectations.
