KFWELD mold raw materials for high-strength, high-purity, high-density high-quality graphite, and the use of CNC machine tools to ensure that mold easy to slag, long life; mold size, reaction, and metal melting after the flow are carefully designed to avoid mold Explosion, welding copper melt splash and other phenomena, easy to use, welding large, small size metal quality as one. KFWELD mold including mold cavity, mold holes, injection holes and other components. Mold making process should be based on a different shape conductor joint mode (-, T, +, etc.), the shape of the mold cavity, size and flow of the molten metal and rigorous design made of. KFWELD mold clamp is used in conjunction with the mold, due to welding a lot of heat generated, so that the mold temperature is often above 200 ℃, can not be hand-held, it must be used for mold clip, for opening and closing the mold.
