be found, Christie then begins its search with existing industry knowledge, internal and external research and trade publications. When pursuing a new supplier, Christie takes a number of steps in identifying and selecting potential metalcasting facilities, including: • Researching firms via available public data, Dun & Brad- street reports and internal supplier questionnaires.


• Visiting and auditing vendors’ capabilities, financial health, industries served and business systems and practices.


• Entering into a non-disclosure agreement and proceeding with an RFQ on a limited number of parts.


• Selecting a supplier based on audit, business, capabilities and cost performance. With Christie manufacturing locations in both Canada and China, geographic limitations rarely present problems. Parts are sourced from a number of manufacturers across the globe. Also, considering the limited size of many castings, shipping costs are a consideration but rarely the determining factor. (In such cases, larger parts typically will be sourced more locally.) To maintain standards with its suppliers (casting and


otherwise), Christie has a proprietary auditing program with extensive questioning and scoring mechanisms for evaluating and rating suppliers. “Suppliers are audited through questions for cur-


rent and historical performance in commercial stature, financial standing, growth, capital investments, customer base, document and order process control as well as quality and design procedures with practical evidence,” said Steward. “Engineering and design capabilities and third-party information also are obtained and reviewed in the evaluation.” New product turnaround time and production lead


times play a critical role in meeting project launch dates and ongoing inventory cycles. Considering these revolv- ing deadlines, Christie has developed its own rapid prototyping division, known as Hyphen. Established in 2000 and officially opened to the public in October 2012, Hyphen offers a number of prototyping services, including stereolithography (SLA), CNC machining and selective laser sintering (SLS). Christie officials expect castings to


continue to play a vital role in the devel- opment of projector technology. Casting capabilities and materials continue to improve, including further weight reduction and improved performance, meaning the company will continue to provide an example of how cast metal components can play a vital role in pro- ducing big results. 


Some applications require smaller, more intricate castings that are usually diecast.


商列表中找出合适的铸造厂。如果无法找到合格供应 商,Christie将根据了解的行业信息启动搜索,研究内部 和外部的信息以及贸易出版物。


在寻求新供应商时,Christie会进行一系列步骤识别和 选择潜在的铸造厂,包括: • 通过现有的公共数据,邓白氏报道和内部供应商调查 问卷进行公司研究。


• 拜访和审核供应商的能力、财务状况、服务行业和商 务系统和生产现场。


• 订立保密协议,并着手对少量产品报价。 • 根据审核,商务,能力和性价比选择供应商。 Christie公司在加拿大和中国都有生产基地,因此很 少存在地域限制的问题。零部件的采购是全球性的。此 外,考虑到大量铸件的尺寸有限,会考虑运输成本,但 基本上不是决定性因素。 (在此情况下,较大的零件通 常会进行本地采购。)


为了维持供应商(铸造以及其他)的标准,Christie对 供应商评估和评价有专有的审核程序,包括大量的调查 问卷和打分机制。


“对供应商考核,是通过对业务方面当前和历史业 绩、财务状况、发展情况、资本投入、客户基础、文档 和订单的过程控制,以及现实生产的质量和设计程序等 方面提出问题,”斯图尔德说:“也取得工程和设计能 力以及第三方的信息,在审核中予以评估。” 新产品的周转时间和研制周期,在满足项目启动日期 和持续的库存周期方面起到至关重要的作用。考虑到这 些周期的最后期限,Christie已经建立了自己的快速成型 部门,被称为Hyphen。Hyphen成立于2000年,2012 年10月正式对外提供服务,其提供了大量的快速成型服 务,包括立体打印(SLA),数控加工和选择性激光烧结 (SLS)。


Christie公司高层预计铸件将继续为 投影装置技术的发展起到至关重要的 作用。铸造能力和材质的不断改进, 包括进一步减轻重量,提高性能,意 味着公司将在金属铸造零部件如何在 产生重大成果方面起到的重要作用, 继续提供例证。 


某些方面需要较小的、更为复杂的铸件, 通常是压铸件。
