After purchasing a batch of metal plate, how should we inspect their quality?How to check the quality of logo metal plate? Follow us to check: How to check the quality of logo metal plate? Quantity and Model Inspection Especially when purchasing metal plate in bulk, it is essential to verify the quantity and model, as this is a basic requirement. Such a basic mistake must never be made. Following this, more detailed inspections should be conducted. Appearance Inspection Appearance inspection is a fundamental testing item, typically conducted by visual inspection of the metal nameplate’s surface by inspection personnel, which requires a high level of experience from the inspectors. Surface Flatness Check whether the surface of the metal nameplate is flat and free of abnormal dents or defects. Surface Color This refers to the surface color, which can be described as a sensory perception. Compare it to the previous standard color to determine if there is a significant deviation. Logo and Text Clarity Since it is a logo metal plate, the inspection of the logo section should be particularly important, especially its clarity and recognizability. It should look comfortable and clear. Dimension Inspection The dimension inspection of logo plate is also a basic item, but it relies on relevant tools for testing rather than visual observation, thereby compensating for the inaccuracies of human vision. Specification dimensions Use measuring tools to measure the dimensions of each part of the logo nameplate to ensure they meet the requirements specified in the specification manual. Shape precision In addition to standard specifications, shape dimensional precision is also critical….

Spray Frame Thickness Requirements of Luggage Hardware

2025-05-09

There is no set standard for the thickness of the spray lacquer frame (electrophoretic coating) required for the Luggage hardware, but the following factors can be used as a First.Luggage hardware industry norm thickness range The thickness of the electrophoretic coating usually ranges from a few microns to several tens of microns, depending on the product requirements and the environment For applications requiring higher corrosion and wear resistance, the coating thickness may be on the thicker side, e.g. some industries may require 60 to 70 microns or even more. Second.Luggage hardware product-specific requirements If we use the metal logos for high-end decoration or in special environments , thicker coatings will require to provide better protection and decoration. Some application scenarios may specify coating thicknesses, such as the national specification GB/T 18593-2010, which specifies a spray thickness of 0.17 to 0.3 mm Third.process parameter control We can control the coating thickness by adjusting electrophoresis process parameters (such as. voltage, time, coating concentration and so on.). In practice, the process parameters need to adjuster by the material properties, surface condition and target performance. Fourth.Luggage hardware quality and performance balance Too thick a coating may affect logo fineness, while too thin a coating may not meet protection requirements. We recommend determining the optimum thickness range experimentally, considering appearance, durability, and processability.

2025-04-29

In the brand label (Brand Tag) production process, to ensure that the label color and customer requirements are consistent is critical, because it is directly related to the brand image and product quality. So the following will be from the testing equipment, testing process, quality control and problem solving, etc., a detailed introduction to how to detect the brand label color is consistent with customer requirements First, the detection equipment Spectrophotometer Principle Spectrophotometer through the measurement of the spectral properties of the object reflection or transmission, can accurately analyze the color of the numerical data, such as chromaticity coordinates color difference and so on. Applications The spectrophotometer is the equipment of choice in brand label color inspection. It allows non-contact measurement of label samples, avoiding damage to the sample while providing highly accurate color data. Brand tag color Difference Meter Principle The colorimeter is a portable color measurement tool that is based on the principle of the spectrophotometer, but is much lighter and easier to use. The colorimeter can quickly measure the color difference value between the sample color and the standard color. Application On the production line, the colorimeter can be used to monitor the label color in real time, to detect and correct color deviation in time. Standard Light Box Principle The standard light source box provides a variety of standard light source environments, such as simulated daylight, simulated store lighting for observing and comparing colors under different light sources. Application In brand tag color inspection, the standard light source box can help inspectors simulate the actual use of the environment, observe the color performance of the label under different light sources to ensure color consistency. Second,inspection process Obtain customer standards Customers usually provide color samples or color values as color standards. The inspector needs to carefully check…

Third. environment and layout management Static electricity and dust control Maintain the humidity in the quality control area at 40%-60%RH, equipped with ionic fan to eliminate static electricity, to prevent the label from scratching due to adsorption of dust in movement. Cleaning: Wipe the countertop with a dust-free cloth + isopropyl alcohol before starting work every day to avoid particles embedded in the brand tag surface. Lighting and Visual Aid Adoption of non-strobe LED lights (color temperature 5000K-6500K) ensures that the details of the brand tag surface are clearly visible, and reduces touching caused by quality inspectors squinting or coming close to observe. Example: A cosmetic labeling factory upgraded its lighting system to increase the distance between the inspector’s head and the label from 15cm to 30cm, reducing the risk of injury by 60%. Space layout optimization We devide the quality inspection table into inspection area, qualified product area and defective product area, and the interval of each area is ≥15cm to avoid collision of labels in movement. Channel design: keep the width of the aisle in the quality inspection area ≥ 1m, to prevent material trucks or personnel walking when knocking over the label stack. Fourth,brand tag the quality inspection process and packaging protection Brand tag staged inspection strategy We divide the quality inspection into the appearance of the initial inspection → functional testing → final re-inspection of three steps, each stage to reduce the number of label handling. Example: an automotive tag factory through the process of reorganization, so that the average number of single piece of tag handling from 6 times down to 2 times, bruising rate decreased by 50%. Temporary fixing and isolation Quality inspection process using transparent acrylic separation frame, the label to be inspected vertically arranged to avoid stacking and extrusion. Labeling: “Handle with…

Brand tag packaging-A

2025-04-26

The packing method of “Brand tag” needs to be comprehensively designed according to its usage, material, size and transportation requirements, and the core objective is to ensure that the label stays flat, dirt-proof and moisture-proof during storage and transportation, and at the same time is easy to use at the end. The following are packing strategies and operational details for different scenarios: First. basic packing material selection Moisture and anti-fouling layer Use transparent OPP self-adhesive bags or PE film to seal single labels to avoid ink or material deformation by moisture. If the label contains metal foil, hot stamping and other processes, additional wrapping bubble wrap or pearl cotton to prevent scratching. Support reinforcement layer Hard labels (such as acrylic, PVC) need to be separated by thick cardboard or EVA foam to avoid collision. Soft labels ( woven labels, stickers) can be rolled on a hard paper tube and fixed with winding film outside. Batch packing 50-100 labels as a group, packaged in kraft paper or corrugated box, filled with shredded paper or air column cushioning. Valuable labels (such as luxury goods tags) are recommended to be packed independently and then into customized foam boxes. Second, transportation protection program Anti-extrusion measures The carton size should be 5-10cm larger than the label set, and the interior should be filled with bubble wrap or inflatable bags to ensure that there is no space for shaking. Shaped labels (such as three-dimensional hot stamping) need to be customized foam grooves to fix the position of each product. Anti-static treatment Electronic labels (such as RFID chip labels) need to be packaged in anti-static bags, the outer box labeled “anti-static” logo. Extreme environment response When exporting to high temperature and high humidity areas, the outer box should be covered with waterproof film and desiccant should be…

Third. Brand tag field simulation tests (user scenario replication) Artificially accelerated wear Method: Use Martindale abrasion meter, load 9kPa pressure, evaluate after 10,000 times of rubbing. Case: A sports brand tag needs to pass 2000 times of friction (simulating 1 year of daily use). Brand tag chemical corrosion test Reagents: 75% alcohol, sweat simulating solution (pH 4.7-7.5), sunscreen (SPF50+). Time: No discoloration, dissolution or loss of adhesion after 24 hours of exposure. Extreme temperature difference test Procedure: -30℃ freezing for 24 hours → 60℃ baking for 2 hours, cycle 5 times. Focus: Check the bonding strength between hot melt adhesive and paint film to avoid delamination. Fourth. Brand tag data analysis and improvement direction Failure mode analysis (FMEA) Common problems: insufficient adhesion of paint film (45%), poor compatibility of substrate (30%), incomplete curing (25%). Improvement case: A brand improved adhesion to 5B by adding corona treatment (dyne value ≥42). Brand tag quality control points Incoming material inspection: surface roughness of substrate Ra≤0.8μm (metal), Dyne value≥38 (plastic). Process monitoring: spraying thickness 20-30μm (wet film), curing temperature ±5℃, time ±10%. Finished product inspection: 10% sampling inspection for each batch, non-conforming products should be traced back to the previous 3 processes. Fifth. industry practice cases Luxury labels UV curing ink + thermal transfer process, passed 3M 810 tape test (adhesion 15N/25mm). Outdoor equipment labels add polyurethane varnish layer, passed 1000 hours QUV test. FMCG labels Optimize water-based ink formulation, pass 24 hours sweat immersion test. Conclusion Detecting whether a Brand tag loses its paint requires a combination of basic laboratory tests (e.g., scratch method, abrasion test) and environmental simulation tests (e.g., humidity, heat, salt spray, UV aging), as well as field simulations (artificial abrasion, chemical corrosion). Optimizing process parameters (e.g., substrate treatment, curing conditions) through failure mode analysis can significantly improve label durability….
