In recent years, China's plastic machine industry has been rapid development,Blister machineVacuum adsorption on the surface of the mold, cooling after molding, widely used in plastic packaging,Lampdecoration, advertising, decoration and other industries. However, at present, it is mainly dominated by large-scale plastic suction machines, and its molding process is constantly changing in the process of development.

The molding process of large-scale blister machine has three elements: the raw materials of large-scale blister machine, forming equipment and setting conditions and forming molds.

Large-scale plastic machine material forming into products, the primary problem is the large-scale plastic machine material formability, that is, the difficulty of forming processing. This is not only related to its own physical, chemical and mechanical properties, but also related to the process of material plasticization, flow, die process conditions. In the past, the solution to this problem mainly relied on human experience, but human experience is limited and cannot satisfactorily solve such problems. Many scholars have done a lot of theoretical and experimental research work, and computer simulation of the forming process has entered the practical application stage. With the increasing variety of large-scale blister machines, the products continue to expand, and the forming process continues to innovate.

With the most innovation of injection molding and extrusion molding,PlateHot forming technology is also developing rapidly. The degree of automation of the equipment is also getting higher and higher, and the computer fully automatic control has been realized in extrusion, injection and thermoforming. However, the design and manufacture of molds still lags behind the development of equipment and process methods, mainly in the low level of mold design and manufacture, long production cycle and short service life.

In the last two five-year plans, high-precision processing equipment has been introduced to carry out technical transformation on mold design and manufacturing, which has brought China's mold manufacturing technology to a higher level. For example, a fully automatic double cylinderWashing MachineComplete set of injection mold, more than 25 inchesTelevisionComplete sets of injection molds, complete sets of injection and compression molds on cars, and micro gears and shafts in precision instruments. It not only meets the requirements of design accuracy, but also greatly shortens the cycle, creating favorable conditions for product replacement.
