Kimya3D prints spare parts for the railway industry with custom PEKK filament

Kimya,技术公司的增材制造材料部门盔甲, continues to provide 3D printing services for the railway industry with its latest project.

为了早在1982年开发的保护盖组件,一家未命名的铁路供应商最近通过Kimya Factory Manufacturing Service向Kimya打印了一小部分聚合物部分。看到盖板的模具不再存在,因此必须在生产前从头开始重新设计备件。该团队使用在公司的研发中心(Kimya Lab)内内部开发了内部内部的内部,该团队能够节省成本和减少交货时间的3D打印保护盖。

皮埃尔·安托恩(Pierre-Antoine Pluvinage), Business Development Director at Kimya, explains, “Designing a traditional mold would have required a longer development time and generated costs that could only be covered by producing thousands of parts. The Kimya Factory offers our partners a fit-for-purpose finished product using our own materials, all in small runs.”

From lab to factory

该项目最初从Kimya Lab开始,Armour为客户提供了定制的Pekk SC细丝。该材料旨在抵抗高达260°C的高温,同时提供阻燃功能,耐磨性甚至耐化学性。因此,符合铁路部门的严格质量标准并至关重要的是满足EN45545标准的火灾和烟气安全要求。

Pluvinage补充说:“这种合作要求我们符合客户业务部门的认证标准。这就是为什么我们决定提出Pekk SC,这是一种直接从我们的研发中心泡菜实验室发出的细丝,因为它符合客户指定的烟雾/火灾标准。”

Without a digital twin or mold to use as a reference, the Kimya Factory engineers were forced to work with a single paper plan they had at their disposal. Despite the original part being made of PVC, the team was able to 3D print a set of PEKK SC versions which successfully made it to end-use.

A spokesperson for the supplier said, “We compared several technologies for manufacturing these parts in small quantities and additive manufacturing proved to be the right choice from the economic, technical and lead time point of view. Assembly testing conducted by ARMOR and the submission of the FAI quality file led to successful completion of the entire quality acceptance process for these additive manufacturing parts. Only 3D printing was able to meet our demands with such efficiency.”

Spare part 3D printing in the transport sector

由于在火车和电车上发现的机械组件的固有复杂性,因此要采购备件的需求非常普遍。不幸的是,这些错误的组件中有许多可以追溯到几十年,这意味着它们的生产线可能不再是运行的,并且无法保证相应的数字文件的存在。正是在这种情况下,3D打印已被证明是维护和车辆升级的宝贵资产。

就在上个月,公共交通公司Azienda Napoletana Mobilità(ANM) enlisted the help of Italian engineering firm3DNAto re-design那不勒斯的公交和电车网络的机械组件。公司反向工程和3 d印制trolley heads’, the parts that connect each tram to the network’s aerial power supply lines. With none of the components available on the market, traditionally manufacturing the assemblies would have resulted in lead times of more than a year.

在其他地方,技术公司Siemens Mobility Services以前曾使用OEM的FDM 3D打印技术Stratasys生产spare parts for the German and UK rail industries。Last year, the company also announced that it would be expanding its rail maintenance operations to Russia, where it has since been supporting the 13 additional high-speed Velaro trains it built for train companyRZD
