such as jewelry, and another rapid machine produces patterns made from crushed Plexiglas (PPMA). Te workhorse wax printer in the shop provides patterns for castings that require a class “A” surface finish. “We don’t want to do millions of pieces,” said Ziemba.
“Our bread and butter, if it’s a quick hitter, will be between 5 and 2,000 pieces. We have a business model that lets us go after unique things with the attitude that we can do it. Tere’s no such thing as we can’t; it’s just a question of how long it will take to get it done. We don’t bat a thousand, but we have a very high success rate on first run through and we provide a finished product. “We tackle the difficult jobs, and that enhances the deliv-
ery requirement and makes it more challenging. On a normal production job of 5 to 7,000 pieces, without any tie-ups from secondary machining or anything, a five-week turnaround is standard. Tat includes building the tooling in-house.” With no sales representatives, the company relies on
word-of-mouth marketing primarily from engineering customers. “We run very thin shells here, which helps enable intricate
detail on the parts. We all use the same ingredients, but it’s our recipe that allows our shells to have the strength we need with less thickness,” said Michele Walla, who runs day-to- day operations. Standard investment casting best practices are present, but the Aristo Cast team likes to work out new angles. Te company has a few special tricks of the trade up its sleeve, particularly when it comes to working with magnesium.
中，没有任何二次加工或其他方面的影响，包含模具制 作在内，5周的交货期成为标准。”
由于没有销售代表，公司依靠口碑营销，主要客户 是工程机械行业。
“我们产品的壁厚很薄，这有助于零部件的摸样可 以做得更复杂。我们使用的材料都相同，但正是我们的 配方使壳体在壁厚更薄的情况下具备了所需的强度，” 负责日常运营工作的Michele Walla说。 尽管熔模铸造的最佳实践标准都已存在，但Aristo
Cast公司的团队乐于提出新的观点。公司拥有一些特殊 的生产技术，特别是与镁合金有关的技术。 “我们从Aristo Cast公司购买各类铸件，他们所提 供的产品质量都高于其他公司。交货准时而且客户的评 价很好，”Jacob说。他的团队通过现场和视频会议与 Aristo Cast公司的工程师直接接洽，确保铸件的设计符 合最终用途和最佳制造工艺的要求。 Ziemba从事熔模铸造工作已超过50年。他把这归功 于16岁时带他入行的Eutectic Engineering公司原来的 合伙人Gene Malinowski。在Aristo Cast公司，他培 养了技术精湛的专家团队。 “随着公司的发展，我们 希望变得更加专业，而这正是公司发展的方向，因为更 高端、更复杂的铸件需要大量的经验，”他说，“我们 的团队已经做的很好，失误几乎为零。”
打破壁垒 “在快速成型方面我们取得了很多令人骄傲的成
This automotive steering assist housing was converted from a sand cast aluminum part weighing 3.5 lbs. to a 2-lb. investment casting, cutting machining time in half and reducing lead time by four weeks.
该汽车转向辅助部件壳体是 2磅的熔模铸件，原来是3.5 磅的砂铸铝铸件，使机加工 时间缩短了一半，交货周期 缩短了4周。
