As the requirements for locking force of steel coil packaging continue to increase, the combination form of strapping joints is also constantly improving. Currently, there are three commonly used joint forms:
1)
Locking type: The strapping joints are combined with iron buckles. It is mainly used for manual bundling and fully automatic bundling machines. The binding force is > 6000N;
2)
Buckle-free type: The strap joints are combined together through stamping deformation (punching and buckling), which can be used in manual strapping machines. The binding force is > 14000N;
3)
Welding type: Connect the strapping joints together by spot welding, mainly used in fully automatic strapping machines, with a binding force of >20000N;
Highly automated packaging units using buckle-free or welded joints have become the development trend of today's steel coil packaging technology.
What are The Internationally Renowned Manufacturers of Steel Coil Packaging Equipment?
The steel coil packaging technology of steel companies in developed countries is quite mature. Major well-known companies have very strict requirements for the packaging of finished steel coils and have formulated corporate standards. This standard, like other technical information, is a corporate secret. Steel coil packaging in steel companies in industrially developed countries generally uses packaging units with a high degree of automation, requiring very few workers. Workers only do some auxiliary work, such as applying internal and external corner guards, sticking paper, and replacing straps.
In the research and development of the technology of
steel coil packaging machine, like other metallurgical equipment, industrially developed countries are far ahead of China. The most representative companies are: SIGNODE, a subsidiary of the Illinois Company in the United States, TITANPACK in Germany, ITIPACK in Italy, etc. Each company has its own focus and its products have their own characteristics.
SIGNODE is famous for its fully automatic strapping machines. It also produces fully automatic strapping heads and packaging materials for fully automatic strapping machines, such as special strapping, metal corner guards, side guards, locks, etc. The maximum locking force of its fully automatic bundling head is 20,000N, which is the highest among similar products.
TITANPACK is a professional factory that produces fully automatic strapping heads. Its product specifications are complete and its performance is superior. The strapping heads used in many packaging equipment in the world are provided by this company, and its maximum locking force is 17,000N.
ITIPACK is a company specializing in the design and manufacturing of various steel packaging machinery. The company uses the fully automatic strapping heads produced by TITANPACK. In terms of steel coil packaging, the company's fully automatic bundling machine is mainly used for bundling "bare coils" (steel coils without external packaging materials).
