Ton barrel blow molding process and characteristics

- Aug 16, 2019-

The container barrel is made up of a combination of an inner container and a metal frame. The inner container is made of low-density polyethylene or high-density polyethylene, which has high strength, corrosion resistance and good hygiene. Plus the external metal frame is safer and more reliable. Economical: Packed in container drums, it can reduce production, storage, transportation and operation costs. Save a lot of manpower and material resources. Storage saves 35% of space compared to traditional packaging, and can be used for loading and unloading, which reduces the hassle of manual handling. Filling: 1 container bucket = 5 200L barrels, reducing the trouble of repeated operations during the filling process, and avoiding waste such as material leakage and sprinkling during the filling process. Today, Xiaobian introduces you to the process and characteristics of the barrel blow molding process, and I hope to help you.

Blow molding is a process that utilizes the good plasticity of thermoplastics to mold a tubular or sheet-like plastic blank that is preheated to a semi-molten state into an open mold, and then closes the mold immediately in the tubular blank. The center is compressed by the air, so that the billet expands and adheres to the wall of the mold cavity. After cooling, the mold is opened, and the formed plastic product can be taken out. Blow molding is limited to the molding of thermoplastics. It is commonly used in the manufacture of hollow products and films for plastic bottles and cans. The molding process includes two stages of manufacturing and blow molding of plastic parisons. The parison is produced by an injection method and an extrusion method. The injection blow molded product has a uniform wall thickness and does not require a trimming process, and there is no blank at the bottom. However, each type of product must use two kinds of molds, and the parison mold must be able to withstand high pressure and have a large investment. This method is only suitable for the production of small quantities of small products.
