[Case Study on Problem Solving] I want to improve the painting yield of laminated yokes.

Contributing to improved yield through resin impregnation treatment! A case where defects that occurred at a rate of 20% to 30% were reduced to zero.

In laminated yokes, coatings are applied for protection against corrosion and for insulation purposes. However, pinholes occur in the coating film, leading to defects, which has raised concerns about finding effective methods to improve yield. In response, our company performed resin impregnation treatment to seal the gaps between layers and prevent the occurrence of pinholes. As a result, we received feedback saying, "The defects that had occurred at a rate of 20% to 30% have been reduced to zero, which has been a great help." [Case Summary (Excerpt)] ■ Issues - In laminated yokes, coatings are applied for protection against corrosion and for insulation, but pinholes occur in the coating film, leading to defects. - Is there an effective method to improve yield? ■ Solution - Conducted resin impregnation treatment to seal the gaps between layers and prevent the occurrence of pinholes. *For more details, please refer to the PDF document or feel free to contact us.
