Scope

Scope: This document provides guidance on the sealing technology for metal aerosol cans. This document is applicable to metal aerosol cans with a diameter of 25.4 mm and a capacity of no more than 1 L; Main technical content: 4. Under a fixed sealing diameter (CD), the influence factors of adjusting the sealing height (CH) need to be considered. 4.1 Aerosol cans 4.1.1 Contact height (h) of the aerosol can The contact height is a fixed value. It is defined as the "standard size", which represents the distance between the plane of the boss and the center of the curvature radius of the two ends of the sealing. The contact height needs to be measured with a dedicated instrument. It is the arithmetic average of three equidistant points around the diameter of each aerosol can. The average value of a batch of aerosol cans is the arithmetic average of all individual results. 4.1.2 Deformation of the rolled edge of the aerosol can's mouth The multi-directional deformation of the rolled edge of the aerosol can's mouth needs to be considered. 4.2 Fixed cover of the aerosol valve 4.2.1 Material thickness (S1) of the fixed cover of the aerosol valve The material thickness of the fixed cover of the aerosol valve directly affects the sealing dimensions (sealing height and sealing diameter). The material thickness of the fixed cover of the aerosol valve depends on the selected material (tinplate or aluminum), with a standard range of 0.24 mm to 0.44 mm. 4.2.2 Type of sealing ring and compression deformation coefficient (S2, f1) 4.3 Sealing technology The appearance of the sealing claws, their curvature radius (generally between 0.8 mm and 1.2 mm), and the number of claw blades, among other related dimensions, are described in FEA 216. 4.3.1 Sealing height (CH) The sealing height (CH) is adjusted according to the contact height (h), the material thickness of the fixed cover (S1), the thickness of the outer sealing ring (S2), and the compression deformatio
