Resin Sand Casting

Advantages of Alkaline Phenolic Resin Sand Casting

• High Mold Strength: Alkaline phenolic resin bonds well with sand, providing strong and durable molds that can withstand high temperatures during the casting process.

• Dimensional Accuracy: The resin-based molds result in castings with high dimensional accuracy, reducing the need for post-casting machining.

• Surface Finish: This process can produce castings with smoother surface finishes compared to traditional sand casting, which reduces the need for finishing work.

• Thermal Stability: Alkaline phenolic resins offer excellent thermal stability, making them suitable for casting metals at high temperatures.

• Environmental Compatibility: The alkaline phenolic resin sand casting process can produce molds with less volatile organic compound (VOC) emissions compared to other resin systems, making it more environmentally friendly.
