Top 3 Tin Box Manufacturer in China - XinPengDa Tins Packaging

What are the specifications for food tin boxes

Tinplate boxes, such as those used for gum, tea, mooncakes, and other products, are commonly referred to as tinplate boxes. Have you ever wondered about the production process involved in making these boxes? Below, Dongguan Tianjia Tin Box Packaging Products outlines the steps involved in the manufacturing process:

 a. Metal Sheets Arrive in Large Rolls

The metal sheets are transported to the box manufacturing factory in the form of large rolls.

 b. Rolls are Cut into Large Sheets

The rolled material is cut into large sheets, which will be further processed.

 c. Coating the Inner Surface of the Box

The side that will become the inner surface of the box is coated with paint. This coating prevents the metal from rusting or reacting with the contents.

 d. Drying the Paint Film

The coated sheets are passed through a drying tunnel to cure the paint.

 e. Dividing Sheets into Smaller Pieces

The large sheets are divided into smaller pieces, with each piece destined to become a box body.

 f. Rolling Each Piece into a Box

Each small piece is rolled into the shape of a box.

 g. Welding the Sides of the Box

The two sides of the rolled box are pressed together and passed through an electric current, which heats the metal surface and firmly welds the two sides together.

 h. Spraying the Inner Wall and Drying

The inner wall of the box is sprayed, and hot air is blown on the outside to dry it.

 i. Forming the Edges of the Box

The box body is passed through a scraper to form the edges of the top and bottom, preparing them to be joined with the box bottom.

 k. Strengthening the Box with Rolling Edges

The rolling edges reinforce the hardness of the tin box.

This is the manufacturing process of tinplate boxes. "Once a partner, always a friend." Dongguan Tianjia Tin Box Packaging Products welcomes your inquiries and looks forward to establishing a long-lasting friendship with you.
