Description: You can use this mold to make necklaces of different shapes. The main material is graphite, which will not affect the purity of the metal during the metal refining process; cooling and heating conditions, with good thermal stability, bring you a refined refining effect. Our ingot mold has good thermal conductivity, can shorten the melting time, save energy, acid and alkali resistance, corrosion resistance, and impact resistance. The core refining mold is suitable for the experiment and melting of non-ferrous metals such as gold, silver, brass, copper, aluminum-zinc, lead, etc., and can also be used for graphite smelting of non-ferrous metals; considering the size of the product, small-volume metal smelting is more suitable. Exquisite craftsmanship, wide range of uses, to meet your daily needs; you can also invite your friends or family members to enjoy the fun of hand-made.
