dryer instead of a hot air dryer?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Desiccant wheel dryers provide a dew point of -40\u00b0C, which is essential for capturing ambient moisture in PC\/ABS.<br \/>\nHot air dryers simply circulate humid air, failing to draw water out of the molecular structure.<br \/>\nProper drying prevents hydrolytic cleavage during the melting phase, preserving impact strength.<\/p>\n<\/div>\n<div style=\"margin-bottom: 30px\">\n<h3 style=\"font-size: 22px;line-height: 1.5em;font-weight: bold;margin-top:

are caused by surface moisture or overheating.<br \/>\nMaintaining the moisture limit below 0.02% is the first critical step.<br \/>\nAdditionally, slowing down the initial injection velocity prevents frictional shear splay on the cavity walls.<\/p>\n<\/div>\n<div style=\"margin-bottom: 0\">\n<h3 style=\"font-size: 22px;line-height: 1.5em;font-weight: bold;margin-top: 24px;margin-bottom:
