2.5l sealed round pail is a part of the rubber and plastic industry, no matter what kind of 2.5l sealed round pail must go through the molding process. The molding process of 2.5l sealed round pail is to make plastic products from phenolic resin, urea-formaldehyde resin, unsaturated polyester resin and other polymers. Its 2.5l sealed round pail processing methods include compression molding, extrusion molding, injection molding, blow molding, rolling molding, etc. Let's take a look at the processing technology of 2.5l sealed round pail in detail.

Processing technology of 2.5l sealed round pail:

1, compression molding in the industry is also known as compression molding. It is a step in the 2.5l sealed round pail processing of thermosetting plastics such as phenolic resin, urea-formaldehyde resin and unsaturated polyester resin.

2, extrusion extrusion, also known as extrusion molding, is a method of using an extruder to heat the resin continuously through the mold and extrude the desired shape of the product. 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 can also be called injection molding. Injection molding is the method of using an injection molding machine to inject thermoplastic melt into a mold under high pressure, and then cooling and curing to obtain the product. 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 resin blank 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, Calender Calender 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 calender rollers that turn opposite, which are then stripped off the calender rollers 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.
