| Description | This is a part of the lid of a lithium ion battery. Xerom has produced several kinds of lids. The photo shows a cross-section of the type produced by stamping one-millimeter-thick aluminum material to a minimum thickness of 0.01 to 0.03 mm. The product specifications include the thickness of the thin-walled part as well as the pressure at which it ruptures. A change of 0.001 mm in the thin wall thickness will lead to a change in burst pressure. It demonstrates the importance of the manufacturing control technologies as well as that of the precision of metal dies and the precision of the bottom dead center of the stamping machine. To achieve quality and mass productivity, we introduced a mechanism for making adjustments of just a few millimeters to the punch length in the course of mass production. This allows us to make fine-tuning with metal dies on the stamping machine. The precision of joining parts is among the key precisions sought from parts to be coined. In the coining process, material may come into the small gap between parts. Because of the small size of the product, this results in non-conformance in most cases. |
