High quality: The casting mold uses high-quality graphite material with low ash content to that the metal purity is not affected during the refining process. It has fast hot and cold conditions and good thermal stability, producing exquisite refining effects. TIP: please be careful before purchasing Check these dimensions. Advantages: The mold has good thermal conductivity, greatly shortening the melting time; good thermal stability, can withstand 2000C, can be heated and cooled quickly, saves time and effort, is resistant to acid and corrosion, can withstand pressure of 89MPA, and has a long service life. Wide range of uses: Casting can be used to test analytical tools and make ingot for gold bars or necklace pendants, the appropriate size allows you to cast metal and make your own jewelry, suitable for experiments and smelting of non-ferrous metals, such as metals such as brass, copper, aluminum, zinc et al.
