Thickness processing: Pressing of lithium-ion battery cover plates.

Achieving high precision with a board thickness of 15μm ± 3μm! A case where the safety valve and cover plate were integrally formed through press processing.

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.
