After manufacturing, sand eye defects are a common issue. For such problems, using metal casting repair adhesive is an effective solution.

Metal casting repair adhesive is a high-performance, high-viscosity glue primarily used for defect repair in the casting industry. It boasts wear resistance, high-temperature resistance, and corrosion resistance, and can cure quickly at room temperature. Once cured, it exhibits excellent strength and stability. Consequently, it can effectively repair the sand hole defects in castings.

Here are the steps to repair casting sand hole defects in castings using metal casting repair adhesive:

Surface Treatment: First, it is necessary to clean and treat the surface defects of the casting. Remove dust and impurities within a 2-3 cm range surrounding the sand hole defects, and ensure the surface has a certain roughness to enhance the adhesion of the adhesive.

2. Gluing: Apply the metal casting repair adhesive to the sand hole defects, ensuring not to use too much to avoid waste and affect the curing effect.

3. Curing: Place the casting coated with the repair adhesive at room temperature to cure naturally. Generally, it takes about 24 hours for the adhesive to fully cure, ensuring the effectiveness of the repair.

4. Processing: After the adhesive patch has fully cured, it can undergo further processing or be used. Due to its excellent wear resistance and high-temperature resistance, the adhesive patch can withstand various processing and usage environments.
