Shenzhen Shi Shi Tong Metal Products Co., Ltd

The company of Alex in the UK is doing electric motors. In the design of a new product, they need to use a  round head machine screw , the specification is M1.5*50mm. Alex found several screw manufacturers, saying that this is too small and long, they can’t do it. Later, Alex found the Shi Shi Tong  screw manufacturer  and asked if we could produce the  round head machine screw  and gave us the drawings of the screw. In the drawing, Alex marked all the dimensions, as well as the required materials and surface treatment. As soon as we saw Alex’s drawings, we knew that this screw was difficult to produce and it was a big challenge for us. If the  round head machine screw  is to be produced, the difficulty of production is very large. Because the screw is too small, and it is made of copper, the copper material is soft. At the time of production, the wire will not be easily corrected, and the beam can not be successfully molded. We told Alex ...

Round head machine screw  can be made in a variety of materials, such as stainless steel, carbon steel, copper, aluminum, and titanium. So, do you know which nickel-plated surface treatment is used when using carbon steel, and which is the nickel-plated liquid additive for round head machine screw? The  round head machine screw  use N-100 barrel plating bright nickel plating bath additives. This is generally used on screws that require bright nickel plating. N-100 additive is a bright additive for barrel nickel plating. It is a combination of the first type and the second type of additive, divided into N-100A open cylinder additive, N-100B supplement additive, respectively in the new dosing, large adjustment plating solution and production process use. N-100 series additives are liquid, soluble in water, no suspended matter, and will not deteriorate after a long time. The pH value is 4~6, the density is 1.10~1.12g/cm*, non-toxic, non-flammable, and non-dang...
