High-Density Board-to-Board Sockets<\/td>\nExcellent. The primary process for Siveras LX70G35. Optimized for multi-cavity, ultra-thin-walled connector grids with wall thicknesses down to 0.15mm.<\/td>\n<\/tr>\n
Precision SMT Micro-Coils<\/td>\nExcellent. High toughness and low outgassing prevent dynamic structural warping, making it ideal for micro-helical coil bobbins and relays.<\/td>\n<\/tr>\n
Low-Gas Industrial Housings<\/td>\nGood. High specific modulus, low outgassing, and excellent high-temperature creep resistance prevent structural distortion in camera module carriers.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/section>\n

LCP-Toray Siveras LX70G35 Fast-Crystallization Guide<\/h2>\n

Molding an ultra-high heat resistant, 35% glass-fiber reinforced LCP like Siveras LX70G35 requires precise gating, extreme thermal limits, and advanced venting to prevent outgassing:<\/p>\n

Because Siveras LX70G35 exhibits extreme flowability (low viscosity) and rapid crystallization speed during peak standard molding at 360\u00b0C, molten resin can seep easily into minor mold gaps, causing parting line 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

Siveras LX70G35 shrinks much less along the flow (0.05%) than perpendicular to it (0.55%). We use Moldflow simulation during our free DFM review to balance gate locations, aligning glass fibers uniformly to prevent component warping and out-of-tolerance dimensions.<\/p>\n<\/div>\n

\n

Mold Temperature Control (Surface Quality)<\/p>\n

We maintain mold temperatures at 80\u00b0C\u2013120\u00b0C using pressurized oil temperature controllers. High mold temperatures maximize surface gloss, reduce weld lines, and prevent surface glass-fibers from floating, ensuring a smooth and non-fibrous finish.<\/p>\n<\/div>\n
