The heat-releasing mold is composed of several parts, including the mold cover, mold cavity, melting chamber, flow channel, and mold clamp, all made of graphite material with exquisite craftsmanship and unique design..Withstanding melting temperatures of metals like copper, steel, and iron; controlling the flow and velocity of molten metal; the welding model is designed with precision. The mold design ensures that the molten welding material can flow autonomously within the cavity, and separates the mold from the welded connection points, guaranteeing high performance and long life. The average thermal welding mold can be used over 50 times, and with simple weld points and careful operation, it can exceed 100 times, making it the best choice for joining different specifications of grounding products.
