The production process of rivet shoulder bag

The production process of rivet shoulder bags mainly includes the following steps, covering the whole process from design to completion:

1. Design and material selection

Design drawings: Design the style of rivet shoulder bags according to market demand or brand positioning. The design drawings include details such as the shape, size, functional division, and rivet decoration position of the bag.

Select materials: Select leather, canvas, PU leather, etc. as the main materials of the bag. Rivets are usually made of metal or metal-plated materials to ensure beauty and durability.

2. Cutting and pattern making

Pattern making: According to the design drawings, use pattern making paper to make paper patterns of various parts of the bag. Mark the selected materials according to the paper pattern to determine the size of each part.

Cutting: Use professional cutting tools to accurately cut leather or other materials into various parts of the bag according to the paper pattern, including the bag body, bag cover, shoulder strap, etc.

3. Punching and rivet decoration

Punching: Punch holes in the corresponding positions of the bag according to design requirements. The position of the punching should be accurate to ensure that the rivets can be symmetrical and beautiful after installation. Common tools include manual punchers, punching machines, etc.

Rivet decoration: Rivets are usually used for decoration or reinforcement, and are usually divided into two categories:

Decorative rivets: used to enhance the appearance, can be round, star-shaped, square and other shapes, the arrangement position and quantity are determined by the design plan.

Structural rivets: used to connect the various parts of the bag, commonly found in the reinforcement parts of the bottom or side of the bag.

Installing rivets: When installing rivets, you need to first pass the pins of the rivets through the pre-punched holes, and then use the rivet tool to rivet and fix the rivets.

4. Sewing and splicing

Stitching: Stitch the various parts of the bag according to the design requirements. Common sewing processes include hand stitching and machine stitching. High-end riveted shoulder bags are generally hand-stitched, using high-strength nylon or polyester threads to ensure that the bag is strong and durable.

Edge processing: The edge processing of the bag is very important, and usually hot edge tools or hot pressing are used to make the edges smooth and avoid wear.

5. Assembly of bag structure

Assemble various parts: Assemble the bag body, bag cover, shoulder strap, bottom, lining and other parts according to the design requirements. Pay attention to adding anti-collision design to the bottom of the bag, such as thickened leather or small foot nails, to ensure the stability of the bag when placed.

Fix the shoulder strap: The shoulder strap usually needs to be reinforced to ensure the load-bearing capacity. The connection between the shoulder strap and the bag body can be fixed by rivets or buckles.

6. Accessory installation

Fasteners and zippers: According to design requirements, install accessories such as metal buckles, magnetic buckles, zippers, etc. It is necessary to ensure that these accessories match the overall style and function of the bag and are firmly installed.

Inner lining and pockets: According to the design of the bag, install the lining fabric and set up inner pockets to classify and store items. The lining material is usually fabric or PU leather, and it needs to be precisely sewn.

7. Quality inspection and finishing

Check the appearance: After the production is completed, perform an appearance inspection to ensure that the rivets and stitching are neat and there are no scratches, stains and other defects on the surface.

Functional inspection: Check whether the various functional parts of the bag are in normal use, such as the adjustment of the shoulder straps, the smoothness of the zipper, etc.

Finishing: If any problems are found, make timely repairs, such as adjusting the tightness of the stitching, trimming excess thread ends, etc.

8. Packaging and delivery

Cleaning and care: Use professional cleaning tools to clean the bag to remove dust and stains.

Packaging: According to sales needs, bags are usually packaged in dust bags to ensure that the product is not damaged during transportation.

Summary

The production process of rivet shoulder bags involves multiple links such as design, material selection, cutting, rivet decoration, sewing, and assembly. The decoration and functionality of rivets enhance the beauty and practicality of the bag. In each production link, precise craftsmanship and meticulous inspection are crucial to ensure that the quality and appearance of the final product meet the standards.
