TWISTER: Titanium Wire for Innovative Spring Technologies and Emissions Reduction

TWISTER通过展示适用于发动机气门弹簧和悬架弹簧的创新连续直接制造工艺，寻求弹簧用钛丝成本降低的一步变化。英国发明的工艺将低成本的颗粒直接固结到线材上。钛弹簧比钢弹簧更高效且密度更低，从而使内燃机更高效，二氧化碳排放量更低。此外，新固结工艺释放的能量输入和CO2排放量显著低于当前的>30批工艺，包括能源密集型真空熔炼和多次锻造。通过领先的技术将钛丝的成本降低一半以上，TWISTER将以经济可行的成本利用其强度和重量特性，为弹簧制造创造重大利益。从TWISTER产生的新产品将是负担得起的，并增加了对更大批量生产车辆的吸引力。

TWISTER seeks a step change in cost reduction of titanium wire for springs by demonstrating an innovative continuous direct manufacturing process applied to both engine valve springs and suspension springs. The UK invented process consolidates low cost particulates directly to wire. Titanium springs are more efficient and less dense than steel springs leading to more efficient combustion engines and lower CO2 emissions. In addition the energy input and CO2 emissions liberated from the novel consolidation process are significantly lower than the current , >30 batch processes, including energy intensive vacuum melting and multiple forging. By more than halving the cost of titanium wire through leading edge technology, TWISTER will allow its strength and weight properties to be utilised at an economically viable cost, creating major benefits for spring making. New products generated from TWISTER will be affordable and increase the attractiveness to higher volume production vehicles.
