Metal containers are commonly used for the production of galvanized steel sheets, tin-plated steel sheets, and chrome-plated steel sheets. Since the steel sheets themselves have a plating layer, they are generally not required to be coated. Galvanized steel sheets are mostly used to produce containers with larger capacity, while tinplates and chrome plates are mostly used to produce containers with smaller capacities. In the production process, the seam welding of the coated steel sheet...
The cost of a PCB tinplate is relatively low because it only sprays tin on the PCB above the pad, while tin plating includes wires as well as tin.

A solder absorber is a tool that is used when repairing electrical appliances to collect the solder melted when the electronic components of the pad are removed. There are two types: manual and electric. A tin absorber is required for maintenance and disassembly of parts. It is even more difficult to disassemble in large-scale integrated circuits. If the disassembly is not good, the printed circuit board may be easily damaged, causing a lot of losses. The general tin suction device is manual...
Tin suction device is a professional tin suction device in electronic production, mainly used in the production of various circuit boards. Its main function is to absorb excess tin around the solder joints on the circuit board. On the one hand, it can prevent the circuit board from short circuiting, on the other hand, it can also save resources. Therefore, many circuit board manufacturers will design the production process of tin absorption in production. So everyone knows what is the principle...
Royston, United Kingdom, on May 26, 2008, tin cans were the most common form of packaging in the food industry, such as soups, jams, meat, pet food and aquatic products. In the final link of the entire processing process, X-ray inspection is the only feasible foreign object detection method because of the packaging form of iron cans. The traditional X-ray inspection system has blind areas in the inspection method, that is, the tank bottom and tank wall, which affects product safety and quality....

Tin is a kind of silvery white and soft metal. It is similar to lead and zinc, but it looks brighter. Its hardness is relatively low, and it can be cut with a knife. It has good ductility, especially when the temperature is 100°C, it can develop extremely thin tin foil, and its thickness can be as thin as 0.04 mm. Tin is also a low-melting metal. Its melting point is only 232°C. Therefore, a candle flame can be used to melt it into a mercury-like liquid with good fluidity. Pure tin has a...
Through the investigation of consumer behavior and packaging relations, two findings were obtained. Find one: Good design is often the perfect unity of shelf visual effects and convenience; Discovery II: Most people think that packaging will cause pollution, but consumers do not think this is a problem when they actually buy. According to statistics of the European Iron and Steel Federation in 2004, the total demand for tinplate packaging market in the world totaled 16.2 million tons, with a...
The benefits of tea tin packaging: 1) Opaqueness: In addition to causing food deteriorating reactions, light can also cause changes in food quality and grade. Tea leaves are more susceptible to deterioration (especially green tea) when exposed to light. The opaque tin can makes the preservation rate of tea the highest, preserves the tea juice and color, taste and aroma. 2) Good tightness: The barrier properties of packaging containers to air and other volatile gases are very important for the...
