Talk about the main classification and advantages and disadvantages of thick film blister production

Date of release:2018-06-06 Author:顺欣 Click:


Thick film blister has a large size, more complex appearance, size requirements are not accurate plastic products, some aspects can replace injection molding, FRP, metal shell, and so on. Blister mold has the advantages of low manufacturing cost, short development cycle, and its cost is 1/10 to 1/20 of the injection mold. It is widely used in automobile interior and exterior decoration, traffic and transportation, building materials, packaging, medical apparatus and instruments, household appliances, culture, education and sanitary ware, sports goods and so on. With the rapid development of the plastics industry today, the field of thick film blister is expanding constantly, and the status of its blister machinery is becoming more and more important, and it is difficult to meet the needs of users. At present, most of the thick film users are mainly imported machinery such as Taiwan production. Its energy - saving, production efficiency, high - difficulty thick - chip blister become the development bottleneck of thick - chip blister machinery. At present, few domestic manufacturers of thick film blister production equipment can replace machinery.

The production of thick sheet blister is a branch of plastic machinery in China at present. In large, all sorts of special, special, special thick sheet suction molding machine sort respect, some product still belong to blank, this is the main difference with industrial developed country. With the development of economic globalization and diversified application of products, the development of thick film vacuum forming machines in China will be accelerated and improved with the help of foreign technology. Especially in today's rapid development of electric vehicles, energy saving and light weight, various styles, the development and application of thick plastic parts become gradually increasing, and the potential market of plastic parts utilization is constantly expanding, and it is estimated that the annual output value will exceed one billion yuan in the next three years. However, the requirements for the thick film blister process and subsequent processing have become more systematic and standardized. It is an opportunity as well as a challenge, riding the wind and waves will sometimes, straight up the wind and sail crowded sea


Classification of thick - chip blister process

1) according to the used molds: there are mainly two kinds of thick blister molds: male mold and female mold.

Advantages of the concave die: the internal surface (A surface) is not in contact with the die, so the surface is smooth and clean, and it is suitable for the parts with the inner surface of refrigerator, refrigerator and freezer. In addition, under the premise of ensuring the size of the inner surface, the thickness of the plate can be reduced, thus saving materials and forming is easy.

Disadvantages: it is not easy to master the size parameters of the mold, and it is easy to enlarge the internal size of the mold, and difficult to reduce.

Features of the punch die: the mold size is easy to reduce, and the B surface is smooth and clean. It is suitable for the parts that require the B surface to be exposed, such as automobile dashboard.

Disadvantages: the material thickness is thicker than that of concave mold molding, the material is stretched to A large extent, and the A surface is rough, while the refrigerator liner, or bathtub, etc. require the A surface to be smooth and clean.

2) thickness of plates and sheets:

At present the market mainly has two kinds of blister processing. One is suction-plastic processing with a thickness of less than 2.5mm. The other is a large thick sheet with a thickness of 3~12mm. These two kinds of processing machines are different, so you should pay attention to the production capacity of the other side when looking for suppliers.
