      Comparison Process head cold and hot processing

      Processing head is generally divided into cold and hot working are two, compare the following three aspects of the two paper processing head were:
      

       
      

      A, head cold material deterioration does not occur, especially suitable for processing stainless steel head;
      

      Thermal processing material deterioration will occur, resulting in decreased corrosion resistance of stainless steel head, stainless steel head is not suitable for processing.
      

      B, cold will not change the size of the contraction caused by cooling, regular shape, size, accuracy and consistency;
      

      Hot forming mold can cause thermal expansion and contraction of the cooling head, the size difference is difficult to control and consistency.
      

      C, to maintain the surface after head cold forming smooth surface of the original material, beautiful appearance.
      

      Surface oxide formed after thermal processing head of serious and difficult to remove.
