The tank head plant, the Mengcun tank head factory manufacturing http://www.hebftc.com/ phone 0317-8210122, Mobile 13722724665 tank head the factory hot and cold processing features, without heating, material deterioration, especially for stainless steel head processing. Deterioration of the material due to the heating occurs, resulting in decreased corrosion resistance of stainless steel head is not suitable for processing stainless steel head. Without heating does not produce dimensional changes caused by cooling contraction, regular in shape, size, accuracy and consistency thermoforming, leading to the mold steel thermal expansion and head cool and shrink the size is difficult to control precision steel tubes and consistency. Without heating, the head forming surface to maintain the smooth surface of the original material, beautiful appearance. Heating head after forming surface oxide is serious and difficult to remove.
