Tin box with hinge manufacturers tell you that tin boxes, which many people call tin cans, are made of tinplate as raw materials, which are packaging boxes made of tinplate through different processes such as welding or stamping and buttoning. The tin box with hinge manufacturer tells you that because tin boxes are made of tinplate, they are also called tinplate boxes.

What is the difference between a tin box and a tin can? In fact, the tin box with hinge manufacturer tells you that there is no strict difference. Generally speaking, square and rectangular are called boxes, and round are called cans.
The structure of the iron box. The tin box with hinge manufacturer tells you that aerosol cans, chemical cans, milk powder cans, and beverage cans are all-welded cans, and the country has formulated relevant product standards for the products. The principle used is that the material to be welded is subjected to pressure by a pair of rotating upper and lower welding wheels with a certain amount of overlap, and through AC low voltage and high current. The contact resistance at the lap of the material is under the action of a large current, which generates a high temperature and makes the material in a plastic-melting state.
The tin box with hinge manufacturer tells you that solder joints are formed under the pressure of the upper and lower electrodes, and each half wave of the welding current forms a solder joint. In this way, the welded material moves at a certain linear speed under the action of the rotary welding roller to form overlapping points, that is, the welding seam.
The tin box with hinge manufacturer tells you that the solder joint distance is proportional to the welding line speed and inversely proportional to the frequency of the welding current. Welding: Under the action of the thermal effect of the current and the mechanical pressure, the fusion junction area (point) where the two metal sheets to be welded are integrated with the metallographic phase, commonly known as the solder joint.
The above information is a tin box with hinge manufacturer's introduction and analysis of the tin box, hope it helps you.
