Case study on solving issues with insert nut pressing in semi-automation *Case study collection available!
We will introduce a case that solved the issue of reducing quality variation due to human factors in the press-fitting of insert nuts!
Recently, the number of resin products has been increasing rapidly. When producing resin products, various issues need to be considered, and we often receive challenges related to insert nut heat press fitting. This time, we received a request to stabilize quality because there was a significant variation in the quality of the press-fitting work for off-the-shelf insert nuts, resulting in about 3% defective products. **Proposal** Since defective products lead to wasted time and costs for parts, we proposed a semi-automatic press-fitting machine that can press four units simultaneously, reducing the time humans are involved as much as possible. **Result** The manual part involves setting the insert nut onto the workpiece and moving the stage to the press-fitting position. By automating the "descend → press-fit → ascend" of the heating element, we eliminated the possibility of inadvertently continuing to apply pressure after the press-fitting was completed. This reduced the burden on the resin workpiece and ensured uniform press-fitting times, resulting in no defective products, which was greatly appreciated. *For more details, please refer to the PDF or contact us.*
