一、项目选择 HKB—250塑壳开关是华通开关厂从美国西屋公司引进的技术,具有70年代末、80年代初的先进水平。该产品于1982年起投入资料消化和一系列国产化工作。1986年底通过了样品试制鉴定,性能达到IEC157—1国际标准。后又通过批试工厂鉴定,投入大量生产。进入国内外市场后,深受广大客户欢迎,需求量不断上升。但引进成本较高(每台成本为130.76元),生产期又短,尚存在一些工艺和材料、产品质量不够稳定等问题。为此,该厂价值工程小组
I. Project selection The HKB-250 molded case switch is a technology introduced by the China Westinghouse Company from Huatong Switch Factory. It has advanced levels in the late 1970s and early 1980s. The product was put into use for information digestion and a series of localization work since 1982. By the end of 1986, the sample had been tested and appraised, and the performance reached the IEC157-1 international standard. After passing the test factory identification, put into mass production. After entering the domestic and foreign markets, it is welcomed by customers and the demand is rising. However, the introduction cost is relatively high (the cost per unit is 130.76 yuan), and the production period is short. There are still some problems such as some processes and materials, and the product quality is not stable enough. To this end, the plant value engineering group
