Key Sentence: The newly authorized single-mode liquid silicone forming mold patent solves the problems of incomplete filling and air bubbles in thin-wall cable silicone parts, lifting production efficiency by over 30%.
On July 28, 2026, Changlan Technology’s utility model patent for liquid silicone single-mode forming molds was officially authorized. The optimized mold structure adds independent exhaust channels and layered feeding runners, effectively eliminating bubbles and shrinkage defects when forming ultra-thin liquid silicone cable insulation and sealing sleeves for new energy vehicles and energy storage equipment.
Traditional molds require repeated trimming and reworking of finished LSR cable accessories, with a defective rate close to 4%. After adopting the new patented mold, the one-step forming yield rises above 99%, cutting raw material waste and labor costs significantly. This mold is compatible with platinum-cured automotive-grade
Liquid silicone rubber and can adapt to mass production of high-voltage cable silicone parts for 800V EV platforms.
Industry equipment manufacturers have launched batch customized mold cooperation services for liquid silicone processing factories. Analysts predict efficient LSR molding molds will become standard supporting equipment for new energy silicone accessory production lines in the second half of the year, helping LSR manufacturers improve delivery capacity and gross profit margins.
