The material selection of the train knob head is very exquisite, and the external contact part is often made of engineering plastics with good insulation performance, strong texture and comfortable feel, which not only ensures the safety of the operator, but also can withstand the wear and tear of frequent operation. Key internal components, such as connecting shafts, gears, etc., are made of metal materials, such as stainless steel or aluminum alloy. Stainless steel high strength, corrosion resistance, suitable for long-term stable work in complex environments; The aluminum alloy is light and has good thermal conductivity, which helps to improve the operating sensitivity of the knob head, while reducing the overall weight of the train and reducing energy consumption.
In the manufacturing process, the production of the train knob head needs to go through many strict processes. First, the shell and internal components are manufactured by precision injection molding or machining to ensure dimensional accuracy and surface quality. Then it is assembled, the various parts are accurately assembled together, and strict quality testing is carried out, including electrical performance testing, mechanical life testing, etc., to ensure that it can work stably and reliably under various conditions. Finally, the surface treatment of the finished product, such as spray painting, electroplating, etc., enhances its beauty and corrosion resistance.
