Electronic cigarettes are also electronic products, to ensure waterproof, dustproof, anti-fall, so that the electronic components inside will not be damaged, to ensure its service life. The fuselage manufacturing of electronic cigarettes generally includes metal-plastic composite molding, TPU or TPE material soft rubber two-color injection molding, silicone rubber molding and other types, and will do special protection treatment for electrical parts such as battery compartment covers and interfaces to achieve the "three-proof" effect of waterproof, dustproof and anti-fall.
Some electronic cigarette fuselage is manufactured by metal + soft rubber wrapping and forming. This method is to place the metal frame in a mold and wrap a layer of TPU or TPE soft rubber around the metal frame. TPU soft rubber has high wear resistance, good processing performance, oil resistance, water resistance, non-toxic and odorless, and can be screened and printed.
