Technology / product information

"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.
