Manufacturing method and system of electronic cigarette shell

The invention discloses a manufacturing method and system of an electronic cigarette shell, and belongs to the technical field of manufacturing and processing.The method comprises the steps that the original size of a base material and the target shell size of the electronic cigarette shell to be manufactured are obtained; according to the original size and the size of the target shell, the expected size and the corresponding stretching control parameters during each time of stretching are determined through a six-step stretching parameter determination model; stretching the base material for six times according to the stretching parameters during each time of stretching; after each time of stretching, obtaining a cross-sectional image, and determining the current size according to the cross-sectional image; judging whether the difference between the current size and the expected size is greater than a preset difference value or not; if yes, giving up one-time stretching, and replacing other base materials; i
