anti-uv pet bottle wholesale is widely loved by dealers and consumers because of its light weight, easy to carry, drop resistance, acid and alkali resistance, so anti-uv pet bottle wholesale quickly took root in the packaging industry in just a few decades. By now, plastic has become an important part of life. Beverages, food pickles and honey have been covered by the anti-uv pet bottle wholesale industry, and even agriculture, veterinary medicine and medical packaging have gradually been monopolized by anti-uv pet bottle wholesale. anti-uv pet bottle wholesale is a part of the rubber and plastic industry, no matter what anti-uv pet bottle wholesale must go through molding processing. Now let's take a look at the processing method of anti-uv pet bottle wholesale.
Processing method of anti-uv pet bottle wholesale:
1, compression molding in the industry is also known as compression molding. It is a step in the processing of anti-uv pet bottle wholesale for thermosetting plastics such as phenolic resin, urea-formaldehyde resin and unsaturated polyester resin.
2, extrusion stretching, also known as extrusion molding, is a method of using an extruder to continuously pass a heated resin through a mold and extrude a product of the desired shape. It has the advantages of extruding products of various shapes, high production efficiency and automated continuous production. The disadvantage is that this method can not be widely processed thermosetting plastics, and the product size is prone to deviation.
3, injection molding is the use of injection molding machine under high pressure thermoplastic solution injection into the mold, and then cooling curing to obtain the product method. The advantages of injection molding are fast production speed, high efficiency, automatic operation, and can form complex shaped parts, especially suitable for large-scale production. The disadvantage is that the equipment and mold costs are high, and the injection molding machine is not easy to clean.
4, blow molding is also called hollow blow molding. Mainly through the pressure of compressed air, the hot fat embryo enclosed in the mold is blown into a hollow product. Blow molding includes two methods: blow molding film and blow molding hollow products. Blow molding is mainly used in the production of film products, various bottles, barrels, cans and so on.
(5) Calendering is a forming method in which resins and various additives are treated as intended and then processed into films or sheets through the gap between two or more calendering rolls that turn opposite, which are then stripped off the calendering rolls and then cooled and formed. Rolling is the main molding method of PVC resin, and it is also the main means of manufacturing films, sheets, plates, artificial leather, floor tiles and other products.
6, foam molding to add the appropriate foaming agent to the foaming material, so that the plastic has a microporous structure process. According to the cell structure, it can be divided into open cell foam and closed cell foam, which is determined by the manufacturing method.
The above is the explanation of the processing method of anti-uv pet bottle wholesale. Do you know it after reading it? I hope it will be helpful to you.
