China makeup packaging at Hoaxin plastic

Since entering the market, plastic bottles like Skin Care Bottles have been widely used by distributors and consumers because of their features of light weight, easy to carry, no fear of falling, and resistance to acids and alkalis. Therefore, plastic bottles have rapidly taken root in just a few decades. Circles. Until now, plastic bottles have become an important part of life. Drinks, food, pickles, and honey have been covered by the plastic bottle industry, and even agricultural, animal, and medical packaging have gradually been monopolized by plastic bottles. But do you know how plastic Skin Care Bottles are made? Plastic bottles are part of the rubber and plastics industry. No matter what kind of plastic bottles, they are molded. Plastic bottle molding process is phenolic resin, urea formaldehyde resin, unsaturated polyester resin and other polymers made of plastic products process. The plastic bottle processing methods include compression molding, extrusion molding, injection molding, blow molding, calendering, and the like. Next we will give you a detailed description of its processing methods.
Plastic bottle processing method
1. Compression molding is also called molding in the industry. It is the first step in the plastic bottle processing process for forming thermosetting plastics such as phenolic resin, urea formaldehyde resin and unsaturated polyester resin.
2. Extruded extrusion, also known as extrusion molding, is a method of continuously heating the heated resin through a die and extruding the desired shape using an extruder. It has the advantages of being able to extrude various shapes of products, has high production efficiency, can be automated and continuous production; the disadvantage is that thermosetting plastics can not be widely used this method of processing, product size is prone to bias.
3, injection molding can also be called injection molding. Injection molding is a method in which an injection molding machine is used to inject a thermoplastic melt into a mold under high pressure to obtain a product by cooling and solidifying the product. The advantages of injection molding are high production speed, high efficiency, automation of operation, and ability to form parts with complex shapes, which are particularly suitable for mass production. The disadvantage is the high cost of equipment and molds, and the injection molding machine is not easy to clean.
4, blowing blow molding is also called hollow blow molding. A method of inflating a hot resin parison closed in a mold into a hollow product is primarily a method of compressing air, and blow molding includes blown film and blown hollow products. The blow molding method is mainly used to produce film products, various bottles, barrels, pots and the like.
5, rolling calendering is the resin and various additives after the intended treatment through the calender after the two or more turns of the opposite calender roll processing into a film or sheet, and then peeled off from the calender roll, and then by Cooling shaping a molding method. Calendering is the main method of forming polyvinyl chloride resin, and is the main method for manufacturing films, sheets, plates, artificial leather, floor tiles and other products.
6, foam molding In the foaming material by adding an appropriate foaming agent, so that the plastic process of microporous structure. The cell structure is divided into open cell foam and closed cell foam, which is determined by the manufacturing method.
