1. What is the difference between turning and cold heading?
Answer: Turning is a machining process that uses a lathe to remove part of the blank or semi-finished material to shape it. This method wastes raw materials and has low processing efficiency, resulting in increased costs and high price. Cold heading is a pressure processing technology in which the blank is formed by air hammer and other equipment. In this way, the crystals of the blank are compressed more densely through the impact force, so that the product can obtain higher strength and toughness, high processing efficiency, and beautiful appearance without turning marks.
2. What is the difference between blue zinc and blue white zinc and other zinc plating?
Answer: Our products are mainly plated with friendly environmental zinc yellow and zinc blue, and so on. And the difference between them is the different colors of zinc plating. The main reason is that when the zinc coating is passivated, different passivation solutions are used. Except the color, the difference is mainly reflected in corrosion resistance. For different corrosion resistance, under the same thickness of zinc plating:
Military green zinc > Color zinc > Black zinc > Blue zinc > Blue white zinc > White zinc
3. Can self-clinch fasteners be finished by knocking or punching?
Answer: For clinch fasteners, it is recommended to use special rivet machine for installation, and do not use hammers or other methods for percussion installation to save costs. Because these installation methods will cause uneven force on the clinch fasteners and seriously affect the pressure riveting effect. If you plan to use a punch to install, you’d better to make a special mould for use.
4. About magnetism?
Answer: Stainless steel itself has no magnetism, but during processing, the steel strip is magnetic during the winding process. It is one-sided to judge whether it is a stainless steel product by magnetism. Even steel can be demagnetized. The scientific identification of stainless steel is the stainless steel identification liquid.
5. About tolerance?
Answer: Generally, the diameter of the screw is the thickness of the thread part, which is in the production and national standards. The diameter of screws has tolerance. For example, 7, 7.7, 7.75, 7.8 belongs to M8 screw, and 5.7, 5.75, 5.8 are screws belonging to M6.
