Pom Rod is a rod-shaped product made of polyethylene oxide (POM) material. In order to ensure the stable quality and compliance with requirements of
POM ROD, quality inspection is very important.
The first method is visual inspection. Appearance inspection is the process of visually observing the appearance characteristics of POM rods to determine whether they have obvious defects, such as bubbles, white spots, cracks, discoloration, etc. This requires sufficient illumination of the
POM Rod, careful observation of the surface and cross-section, and recording of any visible defects.
The second method is size inspection. Dimensional inspection is to verify whether the POM rod meets the specification requirements by measuring its length, diameter, and other key dimensions. You can use tools such as calipers, vernier calipers, and micrometers to measure and compare the measurement results with the product specifications.
The third method is density testing. Density testing evaluates the physical properties of POM rods by measuring their density. Density meters and other equipment can be used for measurement, and the measurement results can be compared with standard values to determine whether the density of POM rods is within a reasonable range.
The fourth method is hardness testing. Hardness testing evaluates the wear resistance and physical properties of POM rods by measuring their hardness. Rockwell hardness tester, Brinell hardness tester and other equipment can be used for hardness testing, and the test results can be compared with the standard values to determine whether the hardness of the POM rod meets the requirements.
The fifth method is tensile strength testing. The tensile strength test evaluates the tensile strength and mechanical properties of POM rods through tensile testing. Universal material testing machines and other equipment can be used for testing, and the test results can be compared with standard values to determine whether the tensile strength of POM rods meets the requirements.
When conducting quality inspections, it is important to use accurate and reliable testing equipment, strictly follow standard operating procedures for testing, and record and analyze test results. For unqualified products, timely measures need to be taken for rectification or return and exchange to ensure product quality and user satisfaction.
The quality inspection of POM rods is an important link to ensure product quality. Through methods such as appearance inspection, size inspection, density inspection, hardness inspection, tensile strength inspection, and melt finger inspection, the quality status of POM rods can be comprehensively evaluated, providing users with high-quality products.
