Process improvement

Based on a customer’s request, we achieved improvement of our process and quality/accuracy.

  • Business solutions
  • Background

    The customer has requested that a lineup of mica plates in increments of 0.02 mm-thick can be made to improve their product characteristics.

  • Challenges

    In the past, the lineup and tolerance were ±0.02 mm for each 0.1 mm, so it was necessary to improve the thickness accuracy in order to achieve the customer’s request.

  • Solutions

    We optimized the mica plate manufacturing process, reviewed management methods, and improved the accuracy of measurement methods so that we could realize mica plate thickness with a tolerance of ±0.01 mm.

  • Conclusion

    We were able to supply products that satisfy the customer’s requirement, and using the products as a springboard, the customer is currently conducting practical tests on devices that are indispensable for playing a part in next-generation power systems.
