We would like to introduce a development case of the "Painting Masking Jig" that our company has worked on. The product has a masking area at the intermediate position inside its cylindrical shape, while all other areas are within the painting range, making it difficult to secure the jig. Additionally, a size equal to or larger than the product's inner diameter was required, which posed a challenge for insertion. We successfully enabled attachment and detachment by utilizing deflection and managed to close the gap between the product and the jig. As a result, we were able to mask the targeted masking area, and the attachment and detachment process was carried out smoothly. 【Case Overview】 ■ Challenges/Background: There is a masking area at the intermediate position inside the cylindrical product, making it difficult to secure the jig. ■ Solution: Enabled attachment and detachment using deflection and closed the gap between the product and the jig. ■ Results/Effects: Successfully masked the targeted masking area and carried out the attachment and detachment process smoothly. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of "laser coating removal on 3D shapes" that our company conducted. There was a challenge in wanting to remove the coating from the top and sides of a circular product with multiple 3D protrusions, which required five processes per location. Additionally, the cost of the fixtures needed for the protrusions was significantly high. We created a rotating fixture and adjusted it so that the surface to be laser processed would be horizontal when rotated. This allowed for a significant reduction in initial and processing costs, resulting in cost savings. [Case Overview] ■ Challenges/Background: Five processes required per location, leading to high fixture costs. ■ Solution: - Created a rotating fixture to ensure the processing surface was horizontal. - Enabled continuous processing by linking the laser machine with the fixture. ■ Results/Effects: Achieved significant reductions in initial and processing costs, leading to cost savings. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of "Reducing personnel and achieving high-quality multi-material molding through two-color molding" that our company conducted. In the resin insert molding process, it was a semi-automatic molding, requiring one operator to be dedicated to the molding machine, resulting in unstable product quality. By switching from semi-automatic molding with a single-color machine to two-color molding, we were able to achieve automatic molding, reducing the workload by approximately one operator. Quality also stabilized, achieving a 4% reduction in process defect rate. 【Case Overview】 ■ Challenge: Operators were dedicated to semi-automatic molding, leading to unstable product quality. ■ Solution: Transitioned from semi-automatic insert molding with a single-color machine to two-color molding. ■ Effects: - Enabled automatic molding, reducing the workload by approximately one operator. - Quality stabilized, achieving a 4% reduction in process defect rate. *For more details, please download the PDF or feel free to contact us.
