Vacuum molding machine application scope of vacuum forming process elements

Large thick slices vacuum molding machine are normally used for which industries product manufacturing? In general, thick slices vacuum forming machine is thick plate plastic blister all raw materials, at the same time, to die as the auxiliary, able to produce all sorts of we want to model and product.

thick slices blister forming machine is the most commonly used plastic sheet include: PVC, acrylic, ABS, PC, PP, HIDP, sunshine board, endurance, PE and so on of this a few kinds big. Thick slices produced by vacuum forming machine products are mainly applicable to the auto parts industry of automobile interior trim, shell, base surrounded by car, electric vehicles and acrylic blister word, advertising light boxes, three-dimensional plate, billboards, advertising boards, the bath crock of bath industry, chairs or the setting wall of decoration industry, all sorts of modelling of movie and TV wall blister and so on.

in addition, the thick slices of vacuum molding machine mold production costs low, forming speed is fast, flexibility is very high, widely applicable industry. If you need to do the product is thick, it is best to provide the length of the material, width, thickness and height and production requirements, such ability can formulate the more appropriate equipment, if there is the picture of the product so much the better.

thick slices vacuum molding machine processing technology, that is, plastic ( Board) Material thermal processing technology, it is one of the plastic secondary processing of industrial technology. It is different from injection molding, extrusion, etc. Such a process, not for plastic resin particles or heated mold molding or with your mouth with cross section continuous forming. Thick slices of vacuum forming machine is cutting down will be part of the plastic material, and then could gain the need to shape, size, also for plastic ( Board) Material, and then heated, the use of mould, vacuum or pressure to slice ( Board) Material deformation, thus meet the requirements of shape and size, supplemented by necessary working procedure, realize the application purpose.

large vacuum forming process has three elements:

the big blister forming equipment and raw materials, to set conditions and forming mold. Blister forming large blister material into products, the first question is a large blister material formability, namely the ease of forming. This is not only related to physical, chemical and mechanical properties of itself, and plasticizing, material and process flow, process conditions of progressive die.

to solve this problem in the past relied on people's experience, but experience is limited, can not successfully solve the problem. Many scholars have conducted a lot of theoretical and experimental research, using computer to simulate the forming process has entered the stage of practical application. As the large blister varieties increased, expanding products, forming process and continuous innovation. With injection molding and extrusion molding innovation most, plate hot forming technology is also developing rapidly. Devices will become more and more high degree of automation, the computer full automatic control, has been implemented in extrusion, injection, hot forming.

but mold design and manufacturing is still lagged behind the development of equipment and process methods, main performance in the low level of mold design and manufacturing, production cycle is long, short service life.
