Among them, tiger stripes, white fog and weld lines on interior parts are the most common. These defects not only affect the appearance texture of automobile parts, but also may reduce the strength and service life of parts, which do not meet the strict standards of automobile production. Therefore, accurately identifying such defects and taking effective solutions is an indispensable link in the injection production of automobile parts and the key to ensuring product quality.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-59511fdd elementor-widget elementor-widget-heading\" data-id=\"59511fdd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">1.
