SINO’s technical strategy, rooted in “Molds as the Foundation, Molding as the Wings,” connects the entire value chain from product design to mass production and delivery. Upstream, we engage with clients’ Original Design Data (ODD),<\/span>get<\/span>t<\/span>ing<\/span> involve<\/span>d<\/span> product development early through Simultaneous Engineering (SE). We provide automotive part mold feasibility analysis (DFM), material selection recommendations, and process optimization solutions, resolving potential issues upfront. Midstream, we integrate the two core links\u2014mold manufacturing and injection molding\u2014achieving deep adaptation between the mold and the molding process. Downstream, we extend to secondary operations (such as welding, painting, assembly) and supply chain management, ensuring delivered products meet “ready-to-assemble” standards.<\/span><\/p>

Our technical synergy advantage is evident:<\/span><\/b> The precision of automotive mold manufacturing directly dictates the dimensional stability of injection-molded parts. SINO utilizes high-end equipment like German DMG MORI five-axis machining centers and Italian FIDIA high-speed milling machines, achieving mold cavity machining accuracy of \u00b10.005mm and surface roughness Ra \u2264 0.8\u03bcm. Simultaneously, the injection molding segment is equipped with 180 to 4,000-ton all-electric and two-platen injection molding machines. Combined with Moldflow analysis technology, we precisely control melt flow, holding pressure, and cooling rates, ensuring the molding yield of complex structural components (e.g., automotive instrument panel carriers, new energy battery housings) exceeds 99.5%.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

SINO’s automotive mold manufacturing business covers molds for automotive interior and exterior trim, powertrain systems, chassis structural components, and new energy three-electric systems (battery, motor, electronic control), possessing the following core capabilities:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\tFor large exterior trim molds like automotive bumpers and door panels, we employ a \"integrated mold base + zoned temperature control\" design, equipped with intelligent hydraulic core-pulling systems. This enables single-shot molding of ultra-large parts up to 2600mm \u00d7 1900mm, with mold life exceeding 1 million cycles.\n\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tIn areas requiring both strength and lightweighting, such as internal structural components, SINO has independently developed \"microcellular foam mold\" technology. We have achieved breakthroughs in various technical difficulties and key points for microcellular foam molds for medium-to-large structural parts, reducing cycle times to under 45 seconds. For example, in an integrated rear floor mold developed for a new energy vehicle manufacturer, CAE simulation optimized the rib layout, solving the strength insufficiency problem of traditional splice processes. The microcellular foam technology achieved a 15% weight reduction while simultaneously increasing production efficiency by 30%.\n\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tFocusing on the lightweighting needs of new energy vehicles, we have developed Carbon Fiber Reinforced Polymer (CFRP) molds. Notably, battery housing molds utilize \"high-gloss, weld-line-free\" molding technology. Through mirror-polished cavities and closed-loop rapid heating\/cooling systems, they achieve a weld-line-free surface on battery housings, enhancing heat dissipation performance.\n\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tProduction lines are equipped with ABB 6-axis robots, automatic gate cutters, and vision inspection systems, enabling unmanned operation from raw material feeding to finished product packaging. The MES system collects over 200 parameters in real-time (injection pressure, temperature, cycle time, etc.), combined with AI algorithms to predict equipment failures. This reduces downtime by 40% and achieves production efficiency 25% higher than the industry average.\n\n\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tAddressing automotive lightweighting and environmental requirements, we extensively apply bio-based plastics, recycled plastics, and long-glass-fiber reinforced materials. For instance, using 30% glass-fiber reinforced PP material for automotive door panel carriers (replacing traditional ABS) achieves a 20% weight reduction and 12% cost saving. Simultaneously, \"microcellular foam injection molding\" technology reduces part density by 10-15% while maintaining structural strength, further optimizing overall vehicle energy consumption.\n\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tA \"three-level inspection\" standard is established: First articles undergo full dimensional inspection using CMMs (accuracy \u00b10.01mm). In-process, online vision inspection systems monitor appearance defects (e.g., sink marks, flash) in real-time. Final inspection includes performance tests for temperature resistance, impact resistance, and aging resistance, ensuring products comply with IATF 16949 and customer-specific standards (e.g., VW PV3900, GM GMW14229).\n\n\t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
