Pin terminals with mini-small diameter

Problems: Difficult to control dimension tolerance for whole pin centers’ diameter?

Solutions: This kind of terminals’ traditional processing method is turning, after the latest stamping technology breaking, Heju replace turning by stamping, ensured pin centers’ diameter controlled within dimension tolerance in everywhere.
3 key points as below:

1. Using several operation steps to rolling(see drawing 1)
2. Both side connected with material strip layout design(see drawing 2)
3. Using ultra precision equipment to processing mold parts(such as PG, JG etc.)
