Obaili Bag Factory: Strict Quality Inspection Process to Ensure Excellent Product Quality
In the bag production industry, quality control is crucial. Today, let's walk into Obaili bag factory, which specializes in the production of various bags such as cooler bags, backpacks, travel bags, briefcases, and drawstring bags, to gain an in-depth understanding of its rigorous and comprehensive quality inspection process. Our factory has always adhered to the persistent pursuit of quality. Every link from raw material procurement to finished product delivery is strictly controlled. Especially in terms of incoming material inspection, a complete and scientific testing system has been established.
In the bag production industry, quality control is the foundation for an enterprise to gain a foothold. Today, let's step into Obaili bag factory and personally experience its almost harsh pursuit of product quality. The factory specializes in the production of various bags including cooler bags, backpacks, travel bags, briefcases, drawstring bags, etc. From the moment the raw materials for customer orders are put into the warehouse, it starts a full range of incoming material inspections, covering multiple key links such as material appearance, color comparison, size, color fastness, fabric tensile strength, sewing tensile strength, finished bag load-bearing test, hardware salt spray test, and fabric heavy metal test. Only after all inspections are qualified will mass production be carried out, creating high-quality bags with professionalism and rigor.
After the raw materials required for customer orders are purchased, the worker will send them for incoming material inspection immediately. Warehouse staff will conduct detailed inspections on raw materials from multiple dimensions, including material appearance, color comparison, color fastness, fabric tensile strength, sewing tensile strength, finished bag load-bearing test, hardware salt spray test, and fabric heavy metal test. If the inner bag of the ice bag is heat-pressed, a waterproof test will be conducted. Only when all these inspections are qualified will mass production proceed.
In the material appearance inspection link, inspectors, with rich experience and professional eyes, carefully check whether there are defects, damages, stains, and other problems on the material surface to ensure that each batch of raw materials has a perfect appearance. In terms of color comparison, the factory is equipped with a professional standard light source color matching lamp box (as shown in Figure 1). By simulating light sources in various environments, it accurately compares the consistency between the material color and the standard color card to ensure that the product color meets customer requirements.

Size inspection is an indispensable part of incoming material inspection. Inspectors use high-precision electronic calipers (as shown in Figure 2) to measure key dimensions such as length, width, and thickness of raw materials. For example, some buckles and other accessories used in cooler bags, backpacks, travel bags, etc., need to be checked for correct size. Electronic calipers have the characteristics of accurate measurement and intuitive reading, which can effectively avoid errors in manual measurement and ensure that the size of raw materials is within the specified tolerance range, laying a foundation for the smooth progress of subsequent production.

Color fastness testing is related to the fading of products in daily use. The factory uses a friction color fastness tester (as shown in Figure 3) for testing. The sample is fixed on the instrument, and the friction cloth of a specific material is used to rub repeatedly under a certain pressure. The color change of the rubbed cloth is observed to judge whether the color fastness is up to standard.

For the detection of fabric tensile strength, the factory uses an intelligent electronic tensile testing machine (as shown in Figure 4). This equipment can accurately measure various data of the fabric when it is subjected to tensile force, including maximum tensile force, elongation at break, etc., so as to evaluate whether the strength and toughness of the fabric meet the production requirements.

Sewing tensile strength testing is also important, as it is related to the firmness of the bag's stitching. The factory uses a special sewing tensile testing instrument (as shown in Figure 5) to simulate the pulling situation in actual use, testing the bonding strength between the sewing thread and the fabric, ensuring that the bag will not have problems such as thread breakage during use.

In order to ensure the quality of finished bags, the factory will conduct load-bearing tests on stress bearing parts such as handles and shoulder straps of the finished bags, especially for products such as cooler bags, backpacks, travel bags, and briefcases. The finished bag is hung on a professional load-bearing test frame (as shown in Figure 6) for oscillation tests. The stress bearing parts of the bag are observed for deformation or damage under the set weight through oscillation, so as to verify the actual bearing capacity of the bag.

Hardware accessories play a key role in bags, and their quality directly affects the service life of bags. For example, all hardware sliders and metal buckles used in cooler bags, backpacks, travel bags, briefcases, etc., as well as eyelets used in drawstring bags, need to be tested before use. In the hardware salt spray test, the factory uses a salt spray test chamber (as shown in Figure 7). Hardware accessories are placed in an environment full of salt spray. After at least 8 hours of testing, the surface of the hardware is checked for corrosion, rust, and other phenomena to evaluate the corrosion resistance of the hardware accessories.

In today's era of increasing environmental awareness, fabric heavy metal testing is particularly important. The factory uses an atomic absorption spectrometer (as shown in Figure 8) to accurately detect the heavy metal content in the fabric, ensuring that the product meets environmental standards and protecting the health and safety of consumers.

Our factory, relying on this complete incoming material inspection system and advanced testing instruments, controls the quality of various products such as cooler bags, backpacks, and travel bags from the source. River, the boss of our factory, has always insisted that in the future, we will continue to improve testing technologies and processes, adhere to the quality bottom line, and provide customers with better and more reliable bag products.
Our factory, in the production of various products such as cooler bags, backpacks, travel bags, briefcases, and drawstring bags, adopts an extremely strict quality inspection process, striving for excellence in every detail from raw materials to finished products. Whether it is the color and size related to appearance, the tensile strength, load-bearing capacity, and corrosion resistance that affect use, or the heavy metal content that ensures health, all are controlled by professional instruments and rigorous standards. Choosing products from Obaili means choosing quality, durability, and peace of mind. Customers are welcome to place your trust in Obaili, experience the high quality bags crafted with professionalism and ingenuity, and let each product play an excellent role in life.
