Suitcases have become indispensable in our daily lives, and almost everyone has them. As a consumer, whether you buy a suitcase online or offline, in addition to choosing a satisfactory appearance and function, you should also focus on its quality. However, we cannot use various machines or conduct violent tests like professional inspection centers to detect. However, the following simple methods can help us better choose a beautiful and durable suitcase.
1. Check the appearance of the case
A comprehensive inspection of the appearance of the suitcase is the first step to ensure that we buy a high-quality suitcase. When checking the appearance of the case, the first thing we need to pay attention to is the workmanship details on its surface. A qualified suitcase should have a fine manufacturing process on its surface and should not have any obvious scratches or flaws. This is not only about beauty, but also a direct reflection of quality.
Next, gently open the suitcase, and we need to carefully examine the condition inside the case to ensure that the interior is flat and smooth, without any cracks or other flaws that may affect use. At the same time, it is also an essential link to check the size of the box. The actual specifications of the product should strictly comply with the design regulations, and the allowable dimensional deviation should be controlled within ±5mm to ensure its compatibility and stability in use.
In addition, the uniformity of the box color is also an important criterion for judging its appearance quality. Uniform and consistent color can not only enhance the overall visual effect, but also reflect the excellent manufacturing process. Finally, from the overall shape, the box should not have any deformation, skewness or imbalance, which will directly affect the use experience and durability of the suitcase.
2. Check the parts: wheels, pull rods, zippers, password locks
When checking the key parts of the suitcase, we need to be meticulous to ensure that every detail meets the use requirements.
- Check the wheels: First of all, the inspection of the wheels is crucial. Try to pull the box for a few steps to observe whether the wheels can turn flexibly and slide naturally in a straight line. In order to test the smoothness of the wheels, we can rotate the suitcase in place to observe whether it can continue to rotate after letting go, and whether there is a jamming phenomenon during the rotation. At the same time, by “listening” to the sound, we can roughly judge the quietness and shock absorption effect of the wheels. If the noise is very loud on flat ground when pushing a suitcase on different grounds, the noise will only be more disturbing after going out. In addition, it is also key to judge whether the wheels are stable. Turn the wheels in the same direction and push forward. If the box can go in a straight line, it means that the axle is stable and it will be easier to push.
- Check the pull rod: Checking the smoothness of the pull rod should also not be ignored. Try to stretch the pull rod and observe whether there is any jamming or slight shaking. If the swing amplitude is too large when the pull rod is gently shaken, it means that there is a problem with the pull rod.
- Check the zipper: For the inspection of the zipper, we should pay attention to its smoothness and its firmness. Although the double-layer zipper may be more difficult to pull than the single-layer zipper for the first time, it is more firm. In order to test the smoothness of the zipper, we can try to pull it repeatedly, paying special attention to whether there is jamming at the corner. And in order to test its firmness, we can poke the zipper with the tip of a pen. If the tip of the pen can easily poke in, then the zipper may be easier to crack.
- Check the password lock: Checking the password lock is also essential. Set the factory password 0-0-0 to the middle, press and hold the unlock button to open the suitcase, and reset the new password. In this process, we need to check whether the password lock has a wheel jam phenomenon and whether the lock is easy to use. Only by ensuring the normal use of the password lock can we safely store valuables in the suitcase.
3. Check the workmanship of the fabric
When checking the workmanship of the fabric of the suitcase, we need to carefully and comprehensively examine every detail. First, confirm whether the lining fixing belt is fastened firmly, and the net bag part should also be carefully checked to ensure that there are no holes to ensure the safety and cleanliness of the luggage during transportation.
Next, we need to carefully observe the overall quality of the fabric. High-quality fabrics should be flat and smooth, and should not have undesirable phenomena such as drawing, thick thread, and bamboo knots. At the same time, the surface of the fabric should not have defects such as cutting and perforation, which may affect the durability and beauty of the suitcase.
In addition, the color difference problem cannot be ignored. During the inspection process, we need to compare the color difference between the front and back pockets to ensure that the colors are coordinated and consistent. At the same time, the colors of the inner and outer pockets should also match each other to present an overall harmonious beauty.
Finally, the quality of the sewing process is directly related to the firmness and service life of the suitcase. Therefore, we must carefully check the sewing part to ensure that there are no quality problems such as bursting, skipped stitches, and missed stitches. Only with exquisite sewing technology can we ensure that the suitcase can withstand various pressures and challenges during use and always maintain a perfect state.
4. Check the tag
The tag, as the “identity card” of the product, carries rich information and is an important basis for us to make wise decisions when purchasing. A qualified and complete tag (or label) should contain the following key information in detail to ensure that consumers can fully understand the basic situation of the product.
- The product name should be clearly marked so that consumers can recognize what type of product it is at a glance. Next, the provision of information such as product standard number, specification (model), and item number will help consumers compare the differences between different products and find the one that best suits their needs.
- A detailed description of the main material (including fabric and lining) is also essential, which is directly related to the comfort, durability, and safety of the product. The name and address of the production unit (or distribution unit) can allow consumers to trace the source of the product and increase their trust in the product.
- The marking of trademarks and grades can reflect the brand value and quality grade of the product, providing consumers with additional purchase references. The existence of product certificates (or inspection marks) is a direct guarantee of product quality, allowing consumers to buy and use with confidence.
- The provision of contact numbers makes it convenient for consumers to contact the production unit or distribution unit in time when they encounter problems and obtain after-sales service. In some cases, the addition of product use (maintenance) instructions is also very necessary, which can help consumers better understand the use and maintenance techniques of the product and extend the service life of the product.
5. Factory Product Testing
As consumers, when purchasing luggage, in addition to the above-mentioned detailed inspections, we can also ask merchants or manufacturers to provide product-related test reports to further ensure the quality and performance of the product. These test reports usually cover a variety of test contents, aiming to comprehensively evaluate the durability and reliability of the luggage. Common test items include the following:
① Running test: It simulates the actual use of the suitcase during transportation. During the test, the suitcase runs continuously for 32 kilometers at a speed of 4 kilometers per hour on a treadmill with obstacles, and the load reaches 25 kilograms. After such a test, the running wheel should still rotate flexibly without blocking and deformation, and the wheel frame and axle should also remain intact without cracking.
② Oscillation test: During the test, the pull rod of the suitcase with a load is unfolded and hung on the back of the oscillator. The oscillator moves up and down at a speed of 20 times per minute. After 500 oscillations, the pull rod function should still be normal without damage.
③ Drop test: Since the suitcase may fall due to improper placement during transportation, the 6 faces, 8 corners, and 12 edges of the suitcase need to be dropped during the test. The drop height is 900 mm when testing the face, and 600 mm when testing the corners and edges. After such a test, the box and its components should be free of damage or destruction.
④Rolling test: It simulates the rolling of the suitcase on an uneven road surface. During the test, the loaded suitcase is tested as a whole on a rolling test machine, rolling 50 times on a slope of -12 degrees (2 times every 2 minutes).
⑤Trolley test: It tests the load-bearing capacity of the trolley case and the firmness of the trolley. By continuously opening and closing, reciprocating and pressing the trolley, the reciprocating fatigue performance of the trolley and the structural firmness of the trolley are tested. Qualified products are required to be pulled and closed 3,000 times, and superior products are required to be pulled and closed 4,000 times. After the test, the trolley has no deformation, jamming, loosening, etc.
In summary, by requiring merchants or manufacturers to provide these detailed test reports, we can have a more comprehensive understanding of the quality and performance of the suitcase, to make a more informed purchase decision.
