Virtual simulation ensures high-yield production and prevents long tooling delays.<\/p>\n<\/div>\n<div style=\"margin-bottom: 30px\">\n<h3 style=\"font-size: 22px;line-height: 1.5em;font-weight: bold;margin-top: 24px;margin-bottom: 12px;color: #111111\">How does mold flow simulation predict warpage in glass-filled polymers?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Glass fibers align parallel to the molten resin flow front, causing anisotropic shrinkage where plastic contracts differently along and across flow vectors.
