New Low-Pressure Casting System for the Access Techcenter in Aachen, Germany

the scrap collecting bay. The first section of the conveyor, about 20 meters long, is horizontal and the belt has been designed with reversed sidewalls to allow operators, located on both sides, to sort and degate the castings in a safe and ergonomic way. The castings will be collected into lateral boxes while the sprues, runners and gates will be transported directly to the scrap collecting area. ■

将把浇口、浇道和冒口输送到废料收集区。传送带的第一 部分长约20m，是水平的，传送带设计有反向侧壁，以 便位于两侧的操作员能够以安全且符合人体工程学的方式 对铸件进行分类和去除浇、冒口。铸件将被收集到侧箱中， 而浇口、浇道和冒口将被直接运送到废料收集区。■

New Low-Pressure Casting System for the Access Techcenter in Aachen, Germany 新型低压铸造系统投入德国亚琛 ACCESS技术中心

Successful cooperation between Access, Howmet Tital and FILL After extensive construction work, a new low-pressure casting plant from Fill has been in operation at the Access TechCenter since February 2022. With the new low-pressure casting plant, Access is expanding its portfolio of alloys that can be processed.

Low-pressure casting for aluminium alloy A205?

The basis for the acquisition of the low-pressure casting system from the Upper Austrian machine manufacturer FILL was an enquiry from an aerospace OEM. This led to a cooperation with the aerospace supplier Howmet Tital, the machine builder FILL and the research institute Access.

The starting point was the question of whether a new compressor housing for the low-pressure range of an engine could be manufactured from the innovative material A205.

Currently, a casting process for compressor rings IMC made of the highly viscous but highly temperature-resistant aluminium alloy A205 is being developed at the plant together with the project partner Howmet Tital. If the parts produced in this way are used in aircraft engines, a weight saving of about 40% compared to conventional titanium components can be expected, which will enable a significant increase in efficiency.

In addition to the expansion of the material spectrum, the plant also offers the possibility of significantly increasing the geometry spectrum. In future, the new low-pressure casting plant will be able to produce castings with diameters of up to 1000 mm.

For the development of the production process, Tital and Access jointly applied for a research project in the aeronautical research program LuFo. The content of this project included the construction of a prototype plant at the Access TechCenter. The requirements for the plant - including low-pressure casting in ceramic moulded shells were defined in close cooperation between the project partners. Based on the defined requirements, Fill

Access技术中心、Howmet Tital公司和FILL公 司成功合作 经过大量的安装工作，Fill公司生产的新型低压铸造 线自2022年2月起在Access技术中心投入运营。通 过新的生产线，Access技术中心将扩大其可加工的合金 产品组合。 A205铝合金可以低压铸造吗？ 采购上奥地利州机械制造商FILL公司的低压铸造线 源于航空航天OEM企业的询价，这促成了航空航天供应 商Howmet Tital公司、机械制造商FILL公司和研究机构 Access的合作。 合作始于解决用创新材料A205铝合金和低压铸造工 艺制造用于发动机的新压缩机外壳。 目前，与项目合作伙伴Howmet Tital公司共同开发 的一种由高粘度、耐高温的A205铝合金制成的压缩机环 IMC的铸造工艺在设备上实验。如果将此工艺制成的铸件 用于飞机发动机，与传统的钛铸件相比，预计重量将减轻约 40%，因此将显著提高能效。 除了扩大材料范围外，该设备还显著提高铸件几何 尺寸的范围。未来，新的低压铸造设备将能够生产直径为 1000mm的铸件。 为开发生产工艺，Tital公司和Access技术中心共 同申请了航空研究项目LuFo中的一个，该项目包括在 Access技术中心建造原型工厂。对工厂的要求包括在 密切合作中确定陶瓷铸壳采用低压铸造工艺。针对指定 的要求，Fill公司被确定为供应商，双方明确了详细的
