Advantages and production of steel drums

- Dec 11, 2019-

The main raw material of steel drums is steel plates. Generally, steel plates are required to have a flat surface, low rigidity, small carbon content, and uniform thickness. Auxiliary materials required to manufacture steel drums include sealants, gaskets, seals, and coatings. The crimping sealant requires good elasticity, strong adhesion, multiple curing components, good chemical resistance and process performance.

The technical field involved in the manufacturing of steel drums is very wide. Generally, the following procedures are required: sheet uncoiling and leveling → cutting and blanking → barrel welding → barrel flanging → barrel body expansion → roll packaging and matching → barrel bottom cover forming and prerolling → surface treatment → inner surface spraying Spray paint on the outer surface → print.

Steel drums have been used as main paint packaging containers for more than 100 years. In years of use, steel drums have been formed into a complete series as well as product standards and specifications. Although steel barrels have also evolved over time, the basic design has remained essentially the same. Mature production and supporting complete production lines are a huge obstacle to the development of any subsequent packaging form.

However, steel drums also have some disadvantages. For example, steel drums are mainly round drums, and some smaller drums have lifting rings. However, the shape of the steel barrel is relatively single, and it is difficult to make more patterns. Different brands of coatings are not easy to form differentiated packaging. Although the development of printing technology can already print exquisite patterns on the surface of steel barrels, most steel barrels have roller ribs on the barrel, which affects the exquisite degree of the pattern and the display effect. In addition, during use, it is difficult for the paint to be used up once per barrel. Therefore, the paint packaging requires better sealing. The sealing performance of the lid of the open steel bucket is average, which is also one of the unsatisfactory dead spots of the steel bucket.https://www.fhpails.com/
