Professional quality inspection of customized pvc three-dimensional advertising words
Publish Time: 2024-12-11
At the end of the production chain of customized pvc three-dimensional advertising words, professional inspection tools and methods are like precision filters, filtering out defects and ensuring excellent quality of finished products.
Accurate measurement of dimensions is the basic level, and tools such as calipers, micrometers, and three-dimensional coordinate measuring machines each have their own functions. Calipers are used to measure the conventional linear dimensions of advertising words, such as the thickness of font strokes, the height and width of characters, with an accuracy of up to 0.1 mm, to quickly verify whether they match the design drawings; three-dimensional coordinate measuring machines are "physical examination artifacts" for complex-shaped advertising words, which can capture three-dimensional contours in all directions, build three-dimensional models through multi-point measurements, compare standard data, control the overall dimensional accuracy, ensure that each arc and angle deviation is within the extremely small tolerance range, and ensure seamless installation.
Appearance quality inspection relies on strong flashlights and magnifying glasses. A strong flashlight illuminates the advertising words at a specific angle to highlight surface flaws, such as uneven paint spraying, bubbles, scratches, etc.; a magnifying glass focuses on the details to examine the fusion of the welding points. If there are gaps or cold welds, they can be seen at a glance to ensure that the appearance is smooth and even in color, which is in line with visual aesthetics.
Structural strength testing is related to the durability of advertising words. The tensile gauge is equipped with a special fixture to simulate outdoor wind pulling and collision impact, test the firmness of welding or splicing parts, and ensure that the parts do not loosen or fall off in harsh environments; the Shore hardness tester gently presses the surface of the PVC material to verify that the hardness meets the material selection standards, prevents the material from being too soft to deform or too hard to crack, and ensures long-term use.
Color detection uses a spectrophotometer to accurately quantify color parameters, compare international standard color cards or customer-customized color samples, and strictly control the color difference range. Whether it is indoor soft light or outdoor strong light, the color is always accurately presented, and the brand recognition is unshakable.
Weathering simulation experiments are essential. Step into the walk-in aging test chamber to simulate high temperature, high humidity, and ultraviolet exposure cycles, accelerate the aging process of PVC, observe the degree of fading, embrittlement, and deformation, and estimate the outdoor life of several years with several weeks of experiments. Optimize the material formula or surface treatment process in advance to ensure that the advertising words are still shining after wind and rain.
From microscopic defects to macroscopic performance, a series of professional testing tools and methods work together throughout the production process of customized PVC three-dimensional advertising words, strictly guarding the quality control, so that each advertising word becomes a reliable publicity highlight on the streets.
