Victrex PEEK 450G High-Temperature Tooling Matrix<\/h2>\n

Molding an unreinforced, high-viscosity semi-crystalline polymer like PEEK 450G requires extreme thermal boundaries to secure proper crystalline development:<\/p>\n

\n
\n

Riscaldamento dello stampo ad olio pressurizzato ad alta temperatura<\/p>\n

To secure the proper semi-crystalline phase (giving PEEK its signature opaque beige color and stiffness), mold temperatures must be maintained continuously at 160\u00b0C\u2013200\u00b0C (320\u00b0F to 392\u00b0F) using oil-heating controllers. Cold molds cause the melt to freeze amorphous, turning parts translucent brown and mechanically weak.<\/p>\n<\/div>\n

\n

Hardened S136 Mirror-Polished Tooling<\/p>\n

Due to the extreme clamping pressures and melt velocities of PEEK 450G, Jucheng\u2019s tooling division uses hardened, corrosion-resistant S136 stainless steel molds. We heat-treat cavities to 52 HRC and design generous draft angles (minimum 1.5\u00b0 to 2.0\u00b0) to ensure clean part release.<\/p>\n<\/div>\n

\n

Ceramic Barrel Melt Management<\/p>\n

Molding is processed between 360\u00b0C and 400\u00b0C (680\u00b0F to 752\u00b0F). Jucheng utilizes specialized, ceramic heater bands and bi-metallic barrels on our presses. Exceeding 420\u00b0C can result in chemical chain fracturing and polymer degradation.<\/p>\n<\/div>\n

\n

Pre-essiccazione prolungata con essiccante<\/p>\n

While PEEK absorbs minimal water, moisture causes hydrolytic splay and weld line degradation. We desiccant-dry PEEK 450G 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
