With the storage of the lunch box, the company's logo can play a long-term role in publicity. So how many methods do you know about children's metal lunch boxes? This article introduces the production process of children's metal lunch boxes in detail.

1. Overall design of children's metal lunch box

    For any product, especially children's products, the design is its soul. Any kind of children's lunch box must not only maximize the protection of the packaged content, but also attract children's attention in appearance, so the design is particularly important. The design drawings can be provided by the customer, or the metal box manufacturing factory can design by itself according to customer requirements.

2. Raw material for children's metal lunch box-tin plated iron

   The general production material of children's metal lunch box is tinplate (tinned steel sheet); the content and specification of tinned material should meet the quality requirements of "International Tinned Steel Sheet" (GB2520). Generally, after confirming the order, we will order the most suitable tin-plated iron material, tin-plated iron material variety, size, etc. according to the recent layout drawing.

Three, make a prototype of the children's metal lunch box

The mold department makes metal lunch box molds according to the design drawings, and sends them to the production department for trial mold production samples. If they are unqualified, they need to continue to repair the mold until the samples are correct before mass production.

4. Typesetting and printing of children's metal lunch boxes

   It should be noted here that the printing of iron materials is different from other packaging printing, not cutting first and then printing, but printing first and then cutting. Both film and typesetting are printed by the printing house after the printing house, and usually provide a template for the printing house to follow the color. During the printing process, it is important to pay attention to whether the printing and color matching can keep up with the template, whether the registration is accurate, and whether there is Stain, whether there are scars, etc.

  After printing, children's metal lunch boxes generally go through two processes: glazing and forming. The purpose of the gloss oil is to protect the ink film, increase the gloss of the printed matter, make the product more beautiful, and enhance the ability to withstand the bending and mechanical impact during canning processing. It should be pointed out that since the manufacturing of children's metal lunch boxes is carried out in an automatic assembly line, printing is one of the key processes, and the substrate is often molded products, and in the molding process of children's metal lunch boxes, there are A considerable part of the process is actually completed before printing. To ensure the integrity of the system, this article does not make a strict distinction between pre-press and post-press processes.

Five, forming process

The metal lunch box container stamping process, whether it is a box or a can, is mostly formed by the principle of metal stamping through two processes of separation and plastic deformation, whether it is a box or a can.

　1) The separation process is a stamping method that separates the stamping part and the sheet material along the required contour line and obtains a certain section quality. The separation process often includes operations such as cutting, blanking, punching, notching, trimming and trimming.

　2) The plastic deformation process is a stamping process that makes the stamping blank undergo plastic deformation without destroying it to obtain the required shape and dimensional accuracy. Usually there are three types of bending, stretching and forming. Bending includes bending, crimping, twisting, bending, rolling, bending, drawing bending and other operations; stretching is mainly deep drawing and thinning and deep drawing; there are many forming methods, including turning, flanging, flaring, Narrowing, forming, crimping, bulging, spinning, shaping, and leveling operations.

  3) The method of making round children's metal lunch box: first cut the iron sheet blank into squares, then roll the blank into a cylinder (ie cylinder) and then solder the formed longitudinal joint line to form a side seal, the cylinder One end (ie the bottom of the tank) and the round end cap are mechanically flanged and rolled and sealed (this is the double crimping seam) to form the can body; the other end is sealed after the product is placed cover. The round bento box container is called a three-piece iron can because it is composed of three parts: the bottom, the body and the lid. The manufacturing process of the three-piece children's metal bento box is: cut the coil into rectangular plates with a shearing machine; paint and print; cut into long strips; roll into a cylinder and weld the side seams; repair the joints and paint Layer; cutting the cylinder; forming grooves or corrugations; pressing out the flanges at both ends; rolling the bottom cover; inspecting and placing them on the pallet and punching forming; this can-making method has basically not changed much for more than 150 years, but it is automated The degree and processing accuracy have been greatly improved. In recent years, the welding seam of the side seal has been changed to fusion welding.

　　 A new canning principle appeared in the early 1970s. According to this principle, the can body and the can bottom are a whole, which is stamped out of a round flat blank and sealed after being filled into the product. This is a two-piece can. There are two forming methods for this kind of can: stamping-thinning and drawing method (ie, punching and drawing method) and stamping-re-stamping method (ie, deep drawing). These technologies are not new in themselves. The punching and drawing method has been used to make bullet casings as early as World War I. The difference in can making is the use of ultra-thin metal and the high production speed (annual output can reach hundreds of millions).

6. After the stamping of the children's metal lunch box is completed, the packaging department is responsible for cleaning and assembling the finished product, putting it into plastic bags and packing. This process is very important work. The metal lunch box must be cleaned before packaging, and then packaged according to the packaging method, and the model number and box number must be properly placed. What should be paid attention to during the packaging process is quality control to minimize the influx of defective products into finished products. Stored after strict inspection.
