Manufacturing Process

Our copper melting crucibles are produced using high-purity raw materials, refined through advanced techniques such as isostatic pressing and high-temperature sintering. This ensures the crucibles have superior density and uniformity. The surfaces are specially treated to enhance anti-oxidation and anti-corrosion properties, prolonging the crucible’s lifespan.

Usage and Maintenance

1. Pre-Use Preparation:
   Gradually heat the crucible to remove moisture and stress before its first use. This step is crucial to prevent damage.
2. Thermal Shock Prevention:
   Avoid severe thermal shocks during use to maintain the integrity of the crucible.
