Problems solved by technology

For plastic packaging boxes, using existing molds for blister molding has low production efficiency, poor adsorption, slow molding speed, and prone to streaks and uneven thickness on the surface, which not only affects the appearance, but also increases the cost of subsequent auxiliary processing. Difficulty, but also lead to high scrap rate after blister molding and large waste of materials

Description

Technical field [0001] The present invention involves the field of suction mold technology. Specifically, it is a plastic -making molding method and plastic molding molds for plastic boxes. Background technique [0002] Plastics is a plastic processing process. The main principle is to soften the flat -exhibition plastic sheet and use vacuum to adsorb on the surface of the mold and shape it in the cavity. Various plastic containers and profiles manufactured by vacuum -suckling molding are widely used in the power industry, civil building materials and electronics, toys, tools, medicine, food packaging, lighting, advertising, decorative lighting industry. [0003] Plastic packaging refers to plastic packaging. Plastic is the main material with synthetic or natural high -molecular resin. After adding a variety of additives, it is ductantly under a certain temperature and pressure, and a type of material that can fix its shape after cooling. The main advantage of using plastic packa...
