轻型，完全可回收的复合式升降门，与所有2019款Jeep Cherokees一样，特别有利，因为对跨界车和运动型多用途车的需求仍然很高。与钢制版本相比，这些举升门模块可节省高达25％的质量，并作为完整组件交付给客户。复合材料具有更大的设计灵活性，更深的拉伸和更紧凑的半径。Magna全系统装配和交付方法的其他优势包括降低整个提升门模块的复杂性，降低工具投资并提高装配厂的产量。
该碳纤维副车架， 这也赢得了无限可能的市场增长奖CAMX 2017年，是一个持续的联合R＆d项目，福特汽车公司的结果。通过用两个模制零件和六个钢零件替换45个钢零件，原型副车架减少了82％，与冲压钢制成的副车架相比节省了34％的质量。目前正在进行车辆级测试。
扭转焊接将塑料支架连接到热塑性面板上，并采用高速扭转运动，产生足够的摩擦热，将它们融合在一起。Magna与技术合作伙伴合作，成为个将扭转焊接用于汽车仪表板的公司。该工艺目前用于2017年斯柯达明锐在欧洲的前面板，并计划很快在北美市场使用它。

This month, Magna collected three first-place awards at the 2018 Society of Plastics Engineers (SPE) Automotive Awards gala in Dusseldorf, Germany. In recognition of its innovative lightweighting efforts enabled by advanced materials, Magna’s thermoplastic liftgate for the 2019 Jeep Cherokee won the body exterior category; its carbon fiber subframe prototype won the chassis category; and its torsional welding joining process won in the enabling technology category.
Lightweight, fully recyclable, composite liftgates, like those found on all 2019 Jeep Cherokees, are particularly beneficial as demand for crossover and sport utility vehicles remains high globally. These liftgate modules achieve up to 25 percent mass savings over steel versions and are delivered as complete assemblies to the customer. Composite materials allow for greater design flexibility with deeper draws and tighter radii. Additional benefits of Magna’s full-system assembly and delivery approach include reduced complexity of the total liftgate module, lower tooling investment and increased throughput at the assembly plant.
The carbon fiber subframe, which also won the Infinite Possible for Market Growth Award at CAMX 2017, is the result of an ongoing joint R&D project with Ford Motor Company. The prototype subframe achieves an 82 percent part reduction by replacing 45 steel parts with two molded parts and six steel parts, as well as a 34 percent mass savings compared to a subframe made of stamped steel. Vehicle-level testing is currently underway.
Torsional welding joins plastic brackets to thermoplastic fascia with a high-speed twisting motion that creates enough friction-based heat to meld them together. Working with a technology partner, Magna became the first to use torsional welding for automotive fascia. The process is currently used for the front fascia of the 2017 Skoda Octavia in Europe, and there are plans to use it soon in the North American market.
