键财机械企业股份有限公司于1973创立于台北，为台湾专司各种螺丝搓牙及割沟机械生产之第一大厂。随着企业发展，2001年11月又设立了键财机械（上海）有限公司。而成立上海键财后，公司产品又增加生产系列的配套设备，如打头机、空心打头机、拉钉打头机等。有鉴于大陆扣件制造及市场需求不断大增，又于平湖投入45,500平方米的厂房，将于2008年底落成。键财目前以1200台的年产量达到相当高的大陆搓牙机市占率。ChienTsaiMachineryEnterpriseCo.,Ltd.wasestablishedinTaipeiin1973andisthelargestplantwithspecialtyontheproductionofvariousthreadrollingandslottingmachinery.Withthedevelopmentofthecompany,itestablishedasubsidiary-JiancaiMachinery(Shanghai)Co.,Ltd.inNov.,2001.WhileaftertheestablishmentofJiancaiMachinery(Shanghai),thecompanystartedtoproduceassociatedequipmentoftheserieslikeheadingmachine,hollowheadingmachineandblindrivetheadingmachineetc..Additionally,demandoffastenersmanufacturingandmarketinChinacontinuouslyincreased,ChienTsaifurthersetup45,500squaremetersofplantinPinghu,itwillbecompletedattheendof2008.Atcurrentstage,ChienTsaigrabstheconsiderablemarketshareofthethreadrollingmachinesinChinawithannualproductionof1200sets.
