Manufacturing Process of Pogopin

　　The manufacturing process of Pogopin involves several precise steps to ensure its high quality and performance.

　　The first step is material selection. As mentioned earlier, high - conductivity metals like copper alloys are commonly used for the pin body, and stainless steel is used for the barrel. The materials need to have good mechanical properties, such as strength and durability, as well as excellent electrical conductivity. After material selection, the raw materials are cut into appropriate sizes for further processing.

　　The next step is machining. The plunger and the barrel are machined to the required dimensions and shapes. Precision machining techniques, such as turning and milling, are used to ensure high accuracy. For example, the inner diameter of the barrel needs to be machined to a very precise tolerance to ensure a proper fit for the plunger and the spring. The surface finish of the parts is also important, as a smooth surface can reduce friction and improve the electrical contact.

　　After machining, the parts are subjected to heat treatment. Heat treatment is used to improve the mechanical properties of the materials, such as hardness and toughness. This helps the Pogopin to withstand the repeated compression and expansion of the spring during use.

　　The assembly process is a critical step. The spring is inserted into the barrel, followed by the plunger. The assembly needs to be done carefully to ensure that the spring is properly compressed and the plunger can move smoothly within the barrel. Specialized assembly equipment is often used to ensure accuracy and consistency.

　　Finally, the finished Pogopin undergoes a series of quality inspections. Electrical performance tests, such as resistance measurement and current - carrying capacity tests, are conducted to ensure that the Pogopin meets the required specifications. Mechanical tests, such as contact force measurement and durability tests, are also carried out to ensure its reliability.
