In the past, NBCHAO’s film coating machines were used to automatically coat films, fabrics, paper, metal sheets, foils, and silicon wafers. This case is another new substrate application—glue on sponge sheets. So what kind of automatic scraping machine is more suitable for applying glue on the sponge, and what are the needs of users? Let's explore together.
Glue on the sponge, a typical application is sponge glue, also called adhesive sponge, with EVA foam as the base material, one or both sides coated with solvent (or hot-melt) pressure-sensitive adhesive, and then easy to peel off Made of isolation paper. Sponge glue is different from glass tape, because sponge is light, soft, elastic, not easy to transfer heat, and has the functions of shock absorption, sound insulation, impact buffer, and heat insulation. Therefore, it is more and more widely used in various industries such as automobile decoration, heat insulation, and electrical refrigeration engineering.
In this user case, the customer scrapes and applies thick glue on the sponge sheet, the thickness of the applied glue is 2mm, and the wet film needs to be dried quickly after the application. According to the user's situation, the sponge sheet has a certain thickness and shape, so it is not necessary to choose vacuum adsorption, but can be fixed with a clamp, and the thickness of the glue 2mm is 2000 microns, which is relatively thick, and the wire rod cannot reach such a thickness, so it can be selected. The scraper is used as a film coating device. In addition, the customer hopes to automatically dispense glue, and finally selects the heating scraper automatic film coating machine and then customizes it with automatic feeding function.
The following are the detailed technical parameters of the scraper heating automatic feeding film coating machine for reference. If you have any questions, please consult the technical engineer of NBCHAO.
