"Impression Technologies Limited (ITL) is a relatively new manufacturing business developing hot forming of aluminium sheet. ITL is already in low / medium volume production for a number of premium car manufacturers and as part of it's growth strategy it now needs to ramp up volumes. As part of the volume ramp up process we need to collect large amounts of data on the HFQ process to give our customers confidence that it is robust and that we understand well the operating parameters of the various stages.These end customers require that the formed parts meet certain mechanical properties (Tensile Strength, Yield & elongation). To ensure we meet these criteria we currently use a portable hardness checker and correlate this to mechanical properties. This equipment is now proving to be not fully capable of checking material properties and hence we are looking to improve the measurement method. This improvement will be necessary for HFQ (Hot Form Quench) to enter new market areas including aerospace, rail and high volume automotive.The vision of this project will be to develop a new, novel non destructive, robust test process that can reliably identify material mechanical properties from a fast inspection methodology. This will be used firstly to ensure 100% of our products meet our material requirements with a fast and reliable process, it will then be used to help refine our process to improve throughput and quality levels whilst reducing product variation.The key objectives will be a process that :-* Is fast (<60 seconds to check a part).* Is repeatable ( with a Gauge R&R result of <30% to meet automotive inspection standards).* Gives a high degree of correlation between measurement output and material properties .* Is non destructive.The project focus will to be to investigate the possibility of using eddy current testing to non destructively test material and then to create, through test & analysis a correlation between eddy current results and material properties.This project is innovative as there is currently no known non destructive, reliable measurement process on the market for aluminium, and whilst an equivalent process has recently been released for steel grades - this is not suitable for translation to non-ferrous materials."

“Impression Technologies Limited (ITL) 是一家相对较新的制造企业，开发铝板热成型。ITL 已经为许多高端汽车制造商进行小/中批量生产，作为其增长战略的一部分，它现在需要提高产量作为产量提升过程的一部分，我们需要收集有关 HFQ 过程的大量数据，以使我们的客户相信它是稳健的，并且我们充分了解各个阶段的操作参数。这些最终客户要求形成。零件满足一定的机械性能（拉伸为了确保满足这些标准，我们目前使用便携式硬度检查仪并将其与机械性能相关联，但事实证明该设备不能完全检查材料性能，因此我们正在寻求改进测量方法。这种改进对于 HFQ（热成型淬火）进入包括航空航天、铁路和大批量汽车在内的新市场领域是必要的。该项目的愿景是开发一种新的、新颖的无损、稳健的测试过程，该过程可以可靠地进行。识别材料机械性能来自快速检查方法。这将首先用于确保我们的产品通过快速可靠的流程 100% 满足我们的材料要求，然后用于帮助完善我们的流程，以提高产量和质量水平，同时减少产品变化。主要目标是过程：-* 快速（检查零件不到 60 秒）。* 可重复（测量仪 R&R 结果 <30%，以满足汽车检查标准）。* 提供测量输出和材料特性之间的高度相关性.* 是非破坏性。该项目的重点是研究使用涡流检测对材料进行非破坏性测试的可能性，然后通过测试和分析建立涡流结果与材料性能之间的相关性。该项目具有创新性，因为目前还没有市场上已知的无损、可靠的铝测量方法，虽然最近发布了针对钢种的等效方法，但该方法不适合转化为有色金属材料。”
