Production process of vacuum molding machine products Union star packaging machinery

About suction plastic products production technology of 1, mold production and processing plastic products according to the requirements of customers to provide samples or specifications, the first is made blister mold, general conditions, are made use of gypsum blister packaging mold, but also useful wooden and metal engraving products mold, plaster mold is made, let the natural drying or drying completely; Secondly, on the basis of the condition of the convex concave surface with 1 - 2 mm drill in does not affect product packaging appearance dips many drill holes, if it is products such as packaging, also have to drill some holes on the edge of the around, so that the suction molding machine blister production, can take out air, mold good drill hole; Finally still have to will be hardened gypsum mould processing, add hard processing method is to use strong alum saturated liquid after soaking dry. After 2, mold processing, dry completely will make good mould into the vacuum chamber on the upper plate, and then according to mold size, plastic loaded into suitable size, and then put the film material in heating wood cabinet, make its completely fixed, then wooden fence along with constant temperature furnace on softening plastic sheet. 3, good will soften processing of plastic with wood cabinet, put in a vacuum chamber, start the inspiratory switch, vacuum indoor air clean, after being plastic cooling, that be the same as the mold of concave type packing or process the mold. 4, blister packaging finishing will suction machine have produced products for trimming is the finished product, then through selling after packaging.
