strategic value between a supplier and its customer base, a number of objectives can be realized for both sides: In the development and implementation of innovative
new products and techniques, growth can be achieved. By streamlining tasks between the parties, greater value
can be created by utilizing each other’s strengths. Structural capabilities can be increased through sharing
knowledge and opening up each other’s resources for use. For an investment casting foundry, changing any of the
processes’ consumable materials presents a sizable risk. Tis is never more prevalent than when considering improve- ments to be made to a shell system. Finding and combining the components to create a shell can present a tortuous pro- cess, which once set, can often be difficult to gain traction of support to develop further. Tis can result in an unwilling- ness to consider an alternative, even in metalcasting facilities that have been using the same system for long periods of time, leaving the plant unable to take chances to potentially improve on its process through the utility of alternative or new materials. With the speed of change presented by an increasingly competitive global market, this course of action in itself presents a notable risk to a foundry’s future profit- ability in the mid to long term. Recognizing these risks, REMET has installed a small
production shell room suitable for offline trialling of materi- als. Adjacent to REMET’s recently expanded European Research and Analytical facility, this will be able to pro- vide shell formulations optimized for a foundry’s specific patterns. Offering a streamlined approach to the trialling procedure, REMET’s technologists can bring their materi- als insight to bear in order to provide suggested, optimized formulations while reducing the burden of risk placed on a foundry for implementing new products and techniques in their own production environment. Te offline testing facil- ity will minimize the impact on production capacity, labor time and scrap rates. Combined with REMET’s outstanding Technical Cen-
tre, this development provides a facility for the benefit of the investment casting industry as a whole. Providing additional capacity for the investment castings of tomorrow to be developed in tandem with the materials required to manu-
facture them. ■ Visit

Sand Casting Technology Gives Pump Manufacturer Advantages 砂型铸造技术助力泵生产企业
Dutch pump manufacturer Nijhuis casts pump hous- ings and wheels weighing up to 800 kg at its Winterswijk, Netherlands, location. Te Dutch firm has already con- cluded several projects with voxeljet. voxeljet operates one of the leading service centers for the on-demand production of sand molds for metal castings and offers the VX4000 high-performance printer that can print sand molds up to 4 x 2 x 1 m. “In particular, companies such as ours, which manufacture
荷兰温特斯韦克的泵制造商Nijhuis公司不仅生产泵 外壳，还有重达800 kg的轮毂。该公司已经与Voxeljet 公司进行了几个项目的合作。Voxeljet公司拥有一个先 进的服务中心，为铸造行业提供按需生产砂型的服务， 其VX4000型号的高性能打印机可打印尺寸为4 x 2 x 1 m的砂型。
Nijhuis公司研发工程师Luke Vrielink说：“尤其是 76 |

新产品和新技术的研发和应用有助于实现共同发展。 通过双方的创新合作，优势互补，可以创造出更大的
价值。
知识和资源共享，可以增强双方的发展能力。 对于精密铸造行业来说，工艺耗材的任何改变将导致 相当大的风险。与考虑对壳型铸造工艺进行改进相比， 这是最为普遍发生的。寻找并使部件结合形成壳型是一 个曲折的过程，一旦开始，这个过程经常是很难获得支 持并进行下去的。结果是，企业往往不愿考虑做出改 变，甚至包括采用这种工艺已经很久的铸造企业，从而 丧失了通过改用新材料提高生产工艺的机会。随着全球 市场的竞争日益加剧，铸造企业采取变革行动的过程本 身对中长期的盈利能力就造成了巨大的风险。 REMET公司意识到这些风险，并建立了一个适合离 线材料测试的小型壳型生产车间。该车间位于REMET 公司新扩建的欧洲研究和分析实验室附近，将可以为铸 造企业特殊模型制模的优化提供壳型工艺支持。REMET 公司的技术专家所提出的简化的测试方法，使他们通过 对于材料的理解认识进而提出可借鉴的、优化的工艺方 法。同时，还减轻了铸造企业在实际生产环境中，采用 新产品和新技术面临的风险。离线测试将把对产能、人 工时间和次品率的影响降到最低。 结合REMET公司出色的技术中心，壳型车间的建立 为精密铸造行业的发展提供了一个有利的工具。今后， 精密铸件产量的增长需与生产所需的材料的研发同步进 行。 ■
