Blister is negative pressure molding machine - principle Union star packaging machinery

Acrylic vacuum molding machine working principle is a principle of exercising the blister is negative pressure molding machine. Vacuum plastic molding process is one of the hot forming method. The exercise of thermal contraction principle, the use of thermoplastic materials, produce the shell system of opening style, as long as the molding is packaging material. Acrylic vacuum molding machine manufacturers resolution for blister, will according to the customer request a plaster mold, take a sample for customer confirmation. After factory redo of copper, because copper is extremely easy conduction temperature, and then can start production. Manufacturers will be customer demand, good resolution, the thickness of the blister to start producing products. Before vacuum molding machine will enlarge the blister of the volume, the exercise of thermal heating machine, arriving at a certain temperature, the will blister paper to pressure on copper, blister paper will form and because of the heat of copper in the shape of the same product. On the copper will henceforth have its official certain grain baidu optimization, the final products will have the same grain. After cutting, decoration, made consistent with requirements of the product. Acrylic on the vacuum suction molding machine molding method make the tensile deformation. Because of this force is easy to implement and control, so the vacuum forming in the earliest time, so far a hot forming method is the most widely used. Is negative pressure molding machine
