Insert overmolding involves a multi-layer process where a metal insert is encapsulated in rigid plastic and subsequently covered with a flexible elastomer layer like TPE or TPU.<\/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 do you prevent plastic from leaking onto metal contact pins during molding?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Preventing plastic flash requires machining mold shut-off lands with tolerances tighter than 0.01 mm. Precision-ground steel lands clamp firmly against the metal insert shoulder, forming a mechanical barrier that blocks molten plastic.<\/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\">Why is preheating metal inserts critical before overmolding?<\/h3>\n<p style=\"font-size: 18px;line-height: 1.8em;text-align: left;margin-bottom: 24px\">Preheating metal inserts to 100\u00b0C reduces the temperature differential between cold metal and molten plastic. Lower thermal gradients prevent the polymer skin from freezing prematurely, reducing residual stresses that cause cracking.<\/p>\n<\/div>\n<div style=\"margin-bottom: 30px\">\n<h3 style=\"font-size:
