Case study on solving the issue of automatic transport insert nut press-fitting *Case study collection available!

We will introduce a case that solved the challenge of considering safety measures to reduce human accidents, in addition to shortening the press-in time for insert nuts and automating the process.

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 the heat press fitting of insert nuts. This time, we received a request to stabilize the quality of the insert nuts used in the pressing work of ready-made products, as there has been a lot of variation in quality resulting in defective products, and there is also a desire to improve safety. **Proposal** Since defective products lead to wasted time and costs for parts, we proposed an automatic six-point simultaneous pressing machine equipped with safety devices such as dual-hand switches and area sensors, to minimize the time humans are involved. **Result** The variation in force applied by humans during stage transportation has been eliminated, allowing for more time to prepare the next workpiece, which has enabled further reduction in working time. Previously, the production capacity was about 300 units, but with automation, it has increased to approximately 1,400 units. As a result, we achieved a cost benefit of about 770,000 yen per month due to reduced labor costs, and we were pleased to recover the initial investment in the machine in about five months. *For more details, please refer to the PDF or contact us.*
