Luggage puller piece is a kind of luggage hardware accessories, its quality inspection is to ensure the overall quality of luggage and the use of an important part of the experience. The following are the detailed steps of the quality inspection of luggage pull piece:
First, appearance check
- Plating quality: check whether the plating on the surface of the luggage puller piece is uniform, bright, no signs of oxidation and rust. The plating layer should have good adhesion and corrosion resistance to ensure the beauty and durability of the puller tab.
- Corner treatment: Make sure the corners of the luggage puller tab are rounded and smooth, and not scratchy, to minimize the damage to the human body in case of accidental collision.
- Logo and pattern: If there is a brand logo, pattern or text on the puller tab, it should be checked to see if it is clear, complete and in the exact position.
Second, function check
- Torque test: According to the specifications and models of the puller tab, apply the corresponding torque to test. For example, the conventional 3# pull tabs rotate 2.5KG left and right, 5# puller tabs rotate 4KG left and right, and so on. During the test, there should be no deformation, breakage or loosening.
- Flexibility: We check whether the puller tab is attach securely to the bag and operates smoothly. The puller tab should be able to open and close easily without any jamming or noise.
Third,Strength test
- Tension test: apply a certain tension to the laggage puller piece to test its load-bearing capacity. The specific value of pullering force can e determine according to the use of the bag and load-bearing needs, but usually should not be lower than a certain standard (e.g. not less than 15LBS). During the test, the pullering piece should damage or deforme.
- Durability test: Simulate long-time use by repeatedly operating the pull tabs to check their durability. During the test, the pull tab should be in good working condition without obvious wear or damage.
Fourth, safety inspection
- Material safety: Check whether the materials used in the puller tab meet the environmental protection and safety standards, such as whether they contain formaldehyde, heavy metals and other harmful substances.
- Edge processing: We ensure that the edges of the puller tabs are round and smooth, with no sharp edges or corners, to reduce the risk of injury during use.
To summarize, the quality check of luggage puller tabs includes many aspects such as appearance check, function check, strength test and safety check. Through comprehensive quality inspection, it can ensure that the quality of puller tabs meets the relevant standards and requirements, so as to improve the overall quality and use experience of bags.
