The increasing trend of working at home and personal printing has benefited the development of the Printer Market. Unlike large-sized car parts, printer parts and electronics are often small but require high accuracy. Most of the tolerance for product dimensions is 0.1mm so that the mold precision must also reach 0.05mm. Moreover, the size chains are related to each other, which leads to resizing when NG is not easy.
Normally, we have to design insert for as many dimensions as we can so later it is easier to correct the tolerance. Designers also study part well and give mold a chance to reprocess when we need to adjust dimension.
Office appliances and Home appliances also strictly with burr. So processing and CAM need a comprehensive strategy to avoid any NG issue.
