The production method of blister mould is to use the principle of heating and air pressure, and use vacuum forming machine to process plastic sheets into various shapes of blister. This is a practical floor tile mold and process mold production technology. It is widely used, fast in production, small in investment, quick in effect and high in efficiency. 1. Equipment and tools A set of vacuum plastic machine, mold, PVC or polyethylene plastic sheet roll (different thickness sheets can be selected according to the production variety). 2、 Production process (1) Production and processing of blister mould: according to user requirements or sample specifications, blister mould shall be made first. Generally, gypsum is used to make blister molds, but wood carving and metal carving products are also used as molds. After the mold is made, let it completely dry or naturally dry. Then, according to the specific situation of the product surface, use a 1-2mm drill bit to drill many small holes in the low recesses that do not affect the appearance of the product packaging. If it is a packaging box, for such products, you must drill some small holes on the four sides so that the air can be discharged during the production of blister. After the mold is drilled, the plaster mold must be hardened. The hardening method is to use concentrated alum. Immerse in saturated solution and dry. (2) Manufacturing method of blister mould: One. After the blister mold is completely processed and dried, place the blister mold on the upper iron plate of the vacuum chamber, and then load the plastic sheet into the applicable specification according to the mold size, and then put the sheet into the heated wooden frame to make it completely fixed, and then place the wooden cabinet and plastic sheet on the thermostatic furnace for softening treatment. Bay. Put the softened plastic sheet and the wooden cabinet into the vacuum chamber, turn on the air suction switch to clean the air in the vacuum chamber, and after the plastic sheet is cooled, obtain the same suction mould as the mould. C。 Finish machining; The finished products are cut and trimmed, and can be sold after packaging.
