PEEK-Victrex PEEK 450GL30 Tooling & Thermal Shrinkage Blueprint<\/h2>\n

Molding a highly structural 30% glass-fiber reinforced PEEK demands extreme thermal boundaries and wear-resistant tool designs to control warpage:<\/p>\n

\n
\n

Controlling Abrasive Tool Wear<\/p>\n

30% short glass fibers act as an aggressive grinding agent under high injection pressures and high melt viscosity (550 Pa\u00b7s). Jucheng\u2019s tooling division prevents cavity erosion by constructing molds with premium hardened tool steel (H13 or S136) heat-treated to 52 HRC, combined with nitriding or PVD wear-resistant ceramic coatings to ensure mold longevity.<\/p>\n<\/div>\n

\n

Managing Anisotropic Shrinkage & Warpage<\/p>\n

Glass-filled PEEK shrinks exceptionally low along the flow (typically 0.20% to 0.40%). We utilize 5-axis CNC machines to cut precise mold cavities and implement balanced cooling paths managed by pressurized water controllers, preventing uneven thermal contraction and structural warping.<\/p>\n<\/div>\n

To secure the proper semi-crystalline phase, mold temperatures must be maintained continuously at 160\u00b0C\u2013200\u00b0C (320\u00b0F to 392\u00b0F) using pressurized oil-heating controllers. Cold molds prevent crystallization, resulting in amorphous, translucent brown parts with compromised mechanical strength and low chemical resistance.<\/p>\n<\/div>\n

While PEEK absorbs minimal water, moisture causes hydrolytic splay and weld line degradation. We desiccant-dry PEEK 450GL30 resin at 150\u00b0C (302\u00b0F) for 3\u20134 hours, keeping internal moisture below 0.02% to secure optimal molecular bonds.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
