Outdoor and Dynamic Process Configurations for Weatherproof Santoprene 121-67<\/h2>\n

With its high-toughness linear matrix and enhanced UV protection package, Santoprene 121-67 processes reliably in intricate molds:<\/p>\n\n\n\n\n\n\n\n
Categoria di processo di stampaggio<\/th>\nDettagli di compatibilit\u00e0 di stampaggio e impostazione del processo<\/th>\n<\/tr>\n<\/thead>\n
Thin-Profile Window Weatherstripping<\/td>\nExcellent. Fully optimized for high-performance architectural glass run channels, structural weather seals, and flexible window gaskets.<\/td>\n<\/tr>\n
Automotive Exterior Trim<\/td>\nExcellent. High UV resistance and dynamic fatigue life are perfect for molding mudguard flaps, under-the-hood bellows, and exterior trims.<\/td>\n<\/tr>\n
Dynamic Flex-Fatigue Joints<\/td>\nGood. Highly compliant with dynamic mechanical setups, providing long-term structural integrity against constant flex-cracking.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/section>\n

Super-Thin Wall Melt Rheology & Flash Matrix<\/h2>\n

Lo stampaggio di un TPV amorfo ad alto flusso come Santoprene 121-67W175 richiede un controllo rigoroso delle linee di divisione per prevenire la formazione di bave, insieme a canali di raffreddamento conformi:<\/p>\n

\n
\n

Thin-Walled Flow & Gate Control (Low Viscosity Shear)<\/p>\n

Because Santoprene 121-67W175 is engineered to fill ultra-thin sections (down to 0.33mm radius), it exhibits extreme non-Newtonian flow behavior under shear. Gates must be sized adequately and injection speeds profiled to prevent premature material freeze-off without causing dynamic gate blush.<\/p>\n<\/div>\n

\n

Micron-Level Flash Prevention<\/p>\n

At melt temperatures of 175\u00b0C\u2013230\u00b0C, highly fluid TPV can easily seep into mold parting line gaps, causing flash. Jucheng\u2019s tooling division uses 5-axis CNC machines to achieve micro-tolerances, keeping mold parting clearances strictly within 0.005mm on premium S136 stainless steel mold cavity blocks.<\/p>\n<\/div>\n

\n

Dynamic Oil Mold Temp & Cooling Control<\/p>\n

We maintain mold temperatures at 20\u00b0C\u201350\u00b0C (68\u00b0F to 122\u00b0F) using pressurized water chillers. Keeping tools cold is critical to freeze the soft elastomeric phase quickly, allowing for automatic, warp-free ejection. Conformal cooling loops are utilized to handle its high shrinkage (1.5%-2.5%).<\/p>\n<\/div>\n

\n

Essiccazione con essiccante e scarico dei volatili<\/p>\n

Asciughiamo la resina grezza in essiccatori a tramoggia a setaccio molecolare a 80\u00b0C (176\u00b0F) per 3 ore. Ci\u00f2 elimina le screziature superficiali e previene microvuoti sulle linee di saldatura, mantenendo l'umidit\u00e0 interna rigorosamente al di sotto dello 0,08%. Fessure di sfiato precise (profondit\u00e0 0,015 mm) sono tagliate lungo le linee di divisione per espellere il gas durante le lavorazioni ad alto fuso.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
