Alvos de Processamento em Ambiente Extremo para Victrex 450G<\/h2>\n

Com sua alta viscosidade e qu\u00edmica semicristalina, o PEEK 450G da Victrex requer perfilamento de alta energia t\u00e9rmica para moldar com sucesso:<\/p>\n\n\n\n\n\n\n\n

Matriz de Ferramentas de Alta Temperatura para Victrex PEEK 450G<\/h2>\n

Moldar um pol\u00edmero semicristalino n\u00e3o refor\u00e7ado, de alta viscosidade, como o PEEK 450G, exige limites t\u00e9rmicos extremos para garantir o desenvolvimento cristalino adequado:<\/p>\n

\n
\n

Aquecimento de Molde com \u00d3leo Pressurizado de Alta Temperatura<\/p>\n

Para garantir a fase semicristalina adequada (que confere ao PEEK sua cor bege opaca caracter\u00edstica e rigidez), as temperaturas do molde devem ser mantidas continuamente a 160\u00b0C\u2013200\u00b0C (320\u00b0F a 392\u00b0F) usando controladores de aquecimento a \u00f3leo. Moldes frios fazem o fundido congelar amorfo, tornando as pe\u00e7as transl\u00facidas marrons e mecanicamente fracas.<\/p>\n<\/div>\n

\n

Ferramentas Endurecidas S136 com Polimento Espelhado<\/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

Pr\u00e9-Secagem Estendida com Dessecante<\/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
