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
