In-mold tapping, also known as in-mold tapping, is a new technology that replaces traditional manual tapping. At present, traditional tapping equipment can no longer meet the needs of stamping products, the efficiency is too low, and the processing time is long. It can not meet the market. The need for in-mold tapping technology makes the stamping die truly automated and efficient, the tapping range can reach a minimum of M0.6, the maximum can reach M45. The precision can reach 0.01mm, and the in-mold tapping technology makes The product that is punched out does not need to be subjected to the second manual tapping. The quality of the extruded product is guaranteed, the surface finish is good, the efficiency is high, and the cost is low. It is widely used in stamping.
