Names of various processes in the production of tinplate boxes

The commonly used molds are divided into drawing molds, trimming molds, pre bending molds, winding molds, blanking molds, closing molds, foot molds, neckline molds, punching molds, milling molds, and cutting molds. The surface punch mold is customized according to customer requirements. By combining these molds in different ways, different products can be made.

1. Lid: divided into two types: inner coil and outer coil.

The inner winding process includes: deep drawing, edge cutting, pre bending, and winding.

The outer winding line includes processes such as deep drawing, edge cutting (which can be omitted if the quality requirements for the winding line are not strict), and winding.

2. Bottom: divided into four types: buckle bottom, seal bottom, pat bottom, and two piece can

Bottom buckle: usually includes cutting (opening) and forming. Sometimes, a set of drawing dies can also be used.

Back cover: including the process of deep drawing.

Filming: The process includes primary drawing, cutting, secondary drawing, pre bending, and wire winding.

Two piece can (usually the same as the inner winding of the lid): includes processes such as deep drawing, edge cutting, pre bending, and winding.

3. Can body: It can be divided into four types: closed can, general bottom buckle, bottom sealing, and bottom tapping.

Closing the can body: including the process of closing, rolling the opening line, and fastening the bottom.

Bottom buckle can body: including the process of bottom buckle and crimping line.

Sealing the bottom of the can body: The process includes rolling the opening line and removing the bottom foot.

Bottom tapping of the can body: including the process of rolling the opening line and the bottom line.

The five processes of cutting, corner cutting, pre bending, forming, and boning are necessary and universal for each can body, so newly developed molds generally do not include these processes.
