Christmas gift tin box production process

Christmas gift tin boxes are green and environmentally friendly packaging products. Naturally, most of their production methods are physical methods. However, there will be subtle differences in the production process of tin boxes, but all the general process steps are as follows:

1. Cutting: Use a shearing machine to cut the tinplate into a can body plate or a stalk cover and a rough bottom according to the size required by the drawing.

2. Trimming and corner cutting: cut off the upper and lower corners at one end of the rectangular bad material, and cut out a gap on the upper and lower pages at the other end, so that the upper and lower ends of the can body can have two layers of plates. The weight of the material to facilitate flanging and sealing. The chamfer can be cut into a right angle, pagoda shape, or obtuse angle; the cut can be cut into a V shape or a U shape.

3. Crimping: Crimping requires the cooperation of a crimping machine to roll the mouth of the bad material of the can body into a small arc. A pre-bending process)

4. End folding: also called hooking. The end folding in the production of tinplate boxes is to make the can body round each other. Use an end folding machine to fold the two ends to the back and front respectively.

5. Forming: It is carried out on a three-roll machine, so that the upper data and the lower one a rotate in the opposite direction. The iron sheet is rolled into a cylindrical shape under the action of pressure and friction in the middle.

6. Flattening: After the end folds on both sides of the tank are hooked to each other, they are flattened by a flattening machine to form a firm

7. Flanging: The bottom is turned 90 degrees outward or inward. The methods of flanging include spinning flanging and bending flanging. The purpose is to seal the can and ensure the quality of the roll seal.

8. Can sealing: It is carried out on the can sealing machine, so that the can body and the bottom of the can can be sealed through a heavy curling, and the process is square bottom, beat bottom, and deducted.

9. Pressing ribs: The reinforcement ribs are pressed on the can body, which mainly plays the role of decorating the tin box, and at the same time facilitates better opening of the lid.
