This is an announcement from Miyama Seiko Co., Ltd. regarding "uneven thickness molding."

Differential thickness processing is a method that changes the thickness of a part of a component that has been press-formed. By achieving different wall thicknesses through integrated molding, which was traditionally done through cutting processes, we have successfully reduced costs. This method is used in applications such as sealing plates for mobile lithium batteries and solenoid components for transmissions. At our company, we have simplified the process and successfully reduced costs by integrally molding the explosion-proof valve of the sealing plate for mobile lithium-ion batteries. 【Features of Differential Thickness Processing】 ■ A method that changes the thickness of a part of a component that has been press-formed ■ Successful cost reduction by achieving different wall thicknesses through integrated molding ■ Adopted for sealing plates for mobile lithium batteries and solenoid components for transmissions *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a development case of press forming of machined products through differential thickness processing. The aim of the development is to shorten the process and eliminate cutting by reviewing the differential thickness forming and processing methods. We have achieved the "press forming of differential thickness cylinders" through process optimization. Please feel free to contact us when you need assistance. [Development Goals] ■ New Method: Differential Thickness Forming ■ Cost Reduction: Process Shortening through Method Review ■ Novelty: Elimination of Cutting *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a development case of press forming for lithium-ion battery cover plates through differential thick processing. The development focused on the integration of cold forging and pressing technology, process shortening through a review of processing methods, and integral processing. The safety valve and cover plate were formed as a single piece through pressing. Please feel free to contact us if you have any inquiries. 【Development Objectives】 ■ New Method: Integration of cold forging and pressing technology ■ Cost Reduction: Process shortening through a review of processing methods ■ Novelty: Integral processing *For more details, please refer to the related links or feel free to contact us.
