How to produce the rigid box?

The process is: cover paper Die cutting-cardboard cutting-grooving-corner pasting-positioning-wrapping-final product.

Here is a breakdown of the process:

1. Cover paper Die cutting: The first step is to cut the cover paper to the required size and shape using a die cutting machine. This will create the outer layer of the rigid box.

2. Cardboard cutting: The cardboard sheets are then cut to the required size and shape using a sheet cutting machine.

3. Grooving: The grooving machine is used to create grooves or creases on the cardboard sheets, which will make it easier to fold the sheets and create the rigid box.

4. Corner pasting: The corners of the cardboard sheets are pasted together using a corner pasting machine to create the rigid structure of the box.

5. Positioning: The cover paper is then positioned on the cardboard sheets, with the help of a positioning machine, to create the outer layer of the rigid box.

6. Wrapping: The cardboard sheets are then wrapped in the cover paper using a wrapping machine.

7. Final product: The final product is a rigid box that is sturdy and durable, with an attractive outer layer that can be customized with designs, logos, or other information.

It's important to note that there can be variations in the process depending on the specific requirements of the rigid box being produced, and the machines used can also differ based on the manufacturing process.
