2. Pressing: Press the tungsten powder into a tungsten needle of the required shape.
3. Sintering: Sintering treatment is carried out at high temperature to give the tungsten needle a certain strength and hardness.
4. Processing: The sintered tungsten needle is finely processed, such as grinding and polishing, to meet the required size and precision requirements.
5. Assembly: Insert the processed tungsten needle into the copper sleeve to ensure that its position is accurate and stable.
6. Inspection: Perform quality inspection on the assembled copper sleeve tungsten needle, such as dimensional accuracy, surface roughness, etc., and it can be used after passing the inspection.
