Release time:
2024-05-21
In the production of tin boxes, sewing is an important manufacturing process. It includes connecting the box and the box cover together by making double slits along their edges. This process creates a secure seal that helps keep the contents inside fresh and unaffected by air and moisture. The stitching process begins with the tinplate sheet cut into the desired shape and size. The sheet is then coated with a protective layer to prevent rust or corrosion. After coating, the tin plate passes through a press machine to press the tin plate to form the main body and lid of the box. Next, the body and the lid are carefully aligned and joined together by double stitching. The first step in this process is to curl the edges of the body and lid in opposite directions. After that, the lid is pushed onto the body when the two edges of the tinplate overlap. The two edges are then pressed together using a series of rollers to form a double slit.

The sewing process is critical to the quality of the final product. It requires precision and accuracy to ensure the safety, airtightness and durability of the seal. The quality of the seam depends on several factors, including the thickness and quality of the tinplate, the alignment of the body and cover, and the pressure and tension applied during the rolling process.
Tin box manufacturers use different types of machinery to stitch the boxes. Some of the most common machines include can sewing machines that use a rotating mechanism, clamping machines that use a punching mechanism, and flanging machines that use a flanging mechanism.
In general, the stitching process is a key part of the tin box manufacturing process. This is a complex and precise operation that requires careful attention to detail to create a reliable and durable product. With high-quality seams, the tin box is powerful and can provide long-term storage solutions for various products.
