The principle is to use a vacuum or compressed air molding method to fix a plastic plate on a concave or convex mold. The sheet, deformed under the condition of heating and softening, and pasted on the cavity of the mold to obtain the desired molded product, which is mainly used in the production of some daily necessities, food, and toy packaging products. Due to the low pressure during forming, the blister mold is made of cast aluminum or non-metallic materials, and the structure is relatively simple. Compression mold: includes two structural mold types: compression molding and injection molding. They are a type of molds mainly used to form thermosetting plastics, and their corresponding equipment is a pressure forming machine. According to the characteristics of the plastic, the compression molding method heats the mold to the molding temperature (generally 103°—108°), then puts the measured compression powder into the mold cavity and the feeding chamber, and closes the mold. The plastic is under high heat and high pressure. It is a softened viscous flow, solidified and shaped into the desired product shape after a certain period of time. The difference between injection molding and compression molding is that there is a separate feeding chamber. The mold is closed before molding. The plastic is preheated in the feeding chamber and is in a viscous flow state. It is adjusted and extruded into the mold cavity under pressure to harden and form. Compression molds are also used to mold some special thermoplastics, such as hard-to-melt thermoplastics (such as polyvinyl fluoride) blanks (cold molding), resin lenses with high optical performance, slightly foamed nitrocellulose car steering wheels, etc. . The compression mold is mainly composed of a cavity, a feeding cavity, a guiding mechanism, an ejecting part, a heating system, etc. Injection molds are widely used for packaging electrical components. The material used in the manufacture of compression molds is basically the same as that of injection molds. High-expansion polystyrene molding mold: It is a mold that uses expandable polystyrene (beads composed of polystyrene and foaming agent) raw materials to mold various desired shapes of foam packaging materials. The principle is that the expandable polystyrene can be steam-formed in the mold, including two types of simple manual molds and hydraulic straight-through foam plastic molds, which are mainly used to produce industrial packaging products. The materials used to make this kind of mold are cast aluminum, stainless steel, bronze and so on.
