proper design of screw bosses is crucial for the stability and durability of plastic components. Screw bosses with a wall thickness of approximately 60 percent of the surrounding wall, rounded transitions at the base to avoid stress concentrations, and reinforcing ribs have proven effective in practice. It is also important not to place screw bosses directly on outer walls in order to prevent sink marks. A well-thought-out design not only improves the quality of the screw connection but also reduces the risk of warping, sink marks, and manufacturing issues. <\/p>","protected":false},"author":1,"featured_media":6662,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[45],"tags":[],"class_list":["post-6649","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-konstruieren-mit-kunststoffen"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.6 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Schraubendom - 4Tec Engineering<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/4tec-engineering.com\/en\/schraubendom\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Schraubendom - 4Tec Engineering\" \/>\n<meta property=\"og:description\" content=\"Die richtige Gestaltung von Schraubendomen ist entscheidend f\u00fcr die Stabilit\u00e4t und Langlebigkeit von Kunststoffbauteilen.
