In the eyes of a high-quality backpack manufacturer, any backpack is a work of art. Before the backpack is officially mass-produced, it must go through multiple steps such as design, material selection, and proofing. As a backpack manufacturer with 20 years of experience, this article fully presents how a backpack can be transformed from a pattern on a sample paper into an exquisite product.
The following is the complete process of backpack production process：
Step One: Design and Development
At this stage, the designer will first fully understand the customer’s design requirements for the product and communicate in complete details; (this step is particularly important, as it can make the subsequent process and communication very simple)
In many cases, the first step has been to decide on the structure and outline of a backpack, and then the designer will design the details based on the concepts, market trends, market forecasts, materials, colors, etc. reflected by the customers.
This way the designer can create a sketch of the backpack, get approval from the sketch and create a sample.
Of course, there are also customers who do not have their own complete ideas. We will also provide samples and catalogs from the sample room to customers as design reference. ” Experienced backpack manufacturers can quickly make plans for customers after communicating with them.
Step 2: Determine raw material procurement
Based on the design plan, it is possible to calculate how much material is needed for the product on the sketch, and the size of each piece of material can be calculated using a printer.
Then the pattern designer uses tools to create modules of different parts of the backpack that correspond to the size and shape, and the purchasing department needs to select the appropriate raw materials and perform calculations.
The selection of raw materials needs to take into account the functionality, quality, cost and other factors of the backpack. Common raw materials include fabric, leather, plastic, metal, etc.
Customized backpack raw material procurement
(Usually a backpack with a simple structure has about 13-17 templates. The more complex the design structure of the backpack, the more templates there are)
Step 3: Cutting and sewing of backpack materials
Cutting is the cutting of raw materials into desired shapes and sizes.
Sewing is sewing the cut raw materials together to form the main structure of the backpack. Sewing is divided into sewing the front panel, sewing envelopes, sewing materials, sewing padding, sewing side bags, sewing accessories, and assembly. Trim materials, install zipper pulls, sew back panels, stand stitch machine and assemble bags.
In this link, various sewing equipment and tools need to be used, such as sewing machines, scissors, needles and threads, etc. This is a delicate job, and any errors will cause financial losses and delays in construction schedule.
Step 4: Backpack Parts Processing
In this link, some parts of the backpack need to be processed, such as zippers, buttons, shoulder straps, pockets, etc. The processing of these parts requires the use of various machines and tools, such as stamping machines, cutting machines, stamping machines, etc.
Step 5: Assembling and debugging the backpack
The processed parts and raw materials are assembled together to form the finished backpack. During the assembly process, attention needs to be paid to the matching of components and the firmness of the assembly. After assembly is completed, the backpack needs to be debugged to ensure that its function and quality meet the requirements.
Step 6: Quality Inspection of Backpack
At this stage, quality inspectors are required to conduct a comprehensive quality inspection on the backpack to ensure that it meets quality standards and customer requirements.
Quality inspection includes appearance inspection, functional testing, durability testing, etc.
Appearance inspection of backpack
- The appearance inspection of the backpack is a preliminary inspection, observing whether the product has defects, the appearance must be smooth, cutting off excess threads, etc.
- Secondly, the printer needs to measure the dimensions of each critical location on the sample to ensure it is consistent with the product data requirements. Different backpack manufacturers have their own error range standards for the backpacks they produce. The standard for Feima bags is that the size error is strictly controlled within 0.3 cm.
Backpack functional test
Functional testing of backpacks. The first thing a backpack has is its functionality. We will use a professional tensile testing machine to measure the tensile performance and load-bearing capacity of the backpack.
The backpack is loaded with 12 kilograms of weight for the up and down pull test. At least 600 repeated tests must be performed. If the shoulder straps of the backpack are not broken or damaged during the test, the product is qualified. Different types of backpacks will of course have different requirements.
For example, a feima travel bag needs to pass a load-bearing test of at least 20 kilograms, while a student backpack only needs to pass a load-bearing test of 5 kilograms.
Some bags also need to be tested for wear resistance, waterproofing, and color fastness. If the product is exported to Europe, it also needs to pass chemical testing to ensure that harmful substances such as nickel and mercury in the product are within safe limits.
Step 7: Packing and Shipping of the Backpack
Backpacks will be packed and transported to the country, port or location designated by the customer.
The packaging needs to be designed according to the characteristics of the backpack and the mode of transportation to ensure the safety and quality of the backpack during transportation.
The above are the basic steps of the backpack production process. Different backpack manufacturers may make adjustments and optimizations according to their own conditions. During the production process, each link requires strict quality control and management to ensure the quality and stability of the backpack. At the same time, we continue to improve and innovate production technologies and processes to improve production efficiency and reduce costs.
