The sports watches we usually wear, most of the straps are made of silicone or rubber. Because in sports, our hands move with a large range of motion, and close contact with the hand skin of the strap is also required to be soft material, so as not to damage the skin. These qualified watch bands are generally beautiful in appearance, with pure colors and smooth surfaces. But since plastic products are notoriously prone to defects, how do these beautiful watch bands achieve such perfection? In addition to focusing on the production process during the injection molding of the watch bands, the use of machine vision defect detection equipment during the finished product inspection stage to eliminate 99.9% of defective products is also essential.
Following is the case study of watch strap defect detection sharing by Intsoft Tech.
