,根据方案,在电子控制的水槽中运作。完工后的零件被送两个不同的部门:压力铸造部门和传统铸造部门。在压力铸造部门,通过压力铸造这一过程使零件成形。压力铸造部门是使用的是自动化机器,与传统铸造相比,循环周期更短。然而,用压力铸造的零件必须具有较高的强度和耐度。从这个部门出来的产品继而被送往上光部门。传统铸造是生产卫生洁具产品另一个方法。在这个部门中,大部分的运作都是通过人工完成较之于压力铸造,它的循环周期更长。.经过成形和铸造后的产品也同样被送往上光部门。成形的部件在上光部门上光。这个步骤可以定义为使用防护材料为产品抛光,使之具有持续永久的光泽。上完光后,产品进入隧道炉。在隧道炉内,将产品加热到1200摄氏度。一段时间后,工人检查产品。然而,很多产品不尽如人意,例如有刮痕。在这种情况下,此类产品将会接受第二次的加热。合格的产品予以包装,不合格的予以销毁。最后,产品在包装部门进行包装和热套。公司一直以来都采用分步成本计算原理以达到最小的成本开销目的。分步成本计算在很多公司中也是一种广泛使用的成本计算理念。此理念在以下成本库中显现:---直接人工:所有在产品生产中参与的工人称为直接人工,这是在每个过程最常见的成本库。---液化石油气-电加热的热水:这个在铸造部门中是最重要的成本元素。---包装:最后一个阶段的成本开销元素,称为最终包装。它包括产品的包装和收缩。---日常开支:这是一家公司在任何阶段都会遇见的成本库元素。它包括折旧、租金、间接人工、材料和各类杂费。为了实现作业成本法的运算,那么就需要分步成本单。因为分布成本计算涉及到的是不止一个产品的成本,很难得到正确的结果。只有在只针对同类产品的时候才能得到正确分步成本的结果。通过分析各零件的生产过程,我们可以看到对于分析来说,零件的准备也同样提供了帮助。首先,通过工作时间记录表来计算完成各个相关的活动所需要的劳动时间。由员工填写的工作时间记录表得知完成各个过程的时间和相关的时间比率。工作时间记录表经过编辑和修改。继而一些过程合并在一起,一些被舍弃。这个阶段以后,会计部门核算出工资,并计算出最后的人工成本。如果能够得知各个产品所需要的活动的数量,那么只要计算产品所消耗的活动成本就能得知最终的产品成本了。为了达到这一结果,需要一些必要的观察和检测,加工成本也应包括在内。根据每个生产活动所需要的空间面积,租金要包括在内,同样的,根据资源消耗情况,能源、折旧和其他一些加工成本都要计算在内。如果活动A需占用2/5的空间,过程B需要1/5,过程C占2/5,那么A活动就需承担2/5的租金、B活动1/5、C活动承担2/5。所有的加工成本都根据这个原则来分配。经典的铸造过程中进行的活动有:成型、装配孔钻、返工、清理设备、钻洞和执行功能。塑模活动的驱动程序是加工时间,钻孔活动的驱动程序是孔数,返工活动的驱动程序是产出的数量,清理设备的驱动程序是总处理时间,钻洞活动的驱动程序是功能孔的总数,载客活动的驱动程序是本部门处理的数量,单位面积上的产品按货物的载体和携带的总面积分配。压力铸造过程中进行的活动有:成型、侧钻洞、安装、切割产品中的多余物质、普通返工、携带在制品、钻具组合孔、套环准备、钻洗手盆孔、钻洗脸盆、产品的返工、x补丁控制、带来在制品、帮助其他部门、填写表格、模具检查、控制在制品、设备和人员的控制、钻水孔等。塑模活动的驱动程序是模具使用侧钻洞的数量。安装程序时,其他产品的设置、安装,及切割产品中多余物质的驱动程序是传入的单位。普通返工的驱动程序也是传入的单位,携带在制品的驱动程序是输出的数量。钻孔具组合和套环准备得驱动程序是输出的数量,洗手盆、洗脸盆钻孔的驱动程序是洗手盆、洗脸盆的数量。产品的返工和X补丁控制的驱动程序是输出的数量。携带在制品的驱动程序是传入的在制品。帮助其他部门、填写表格、模具检查、在制品控制、设备和人员的控制、钻水孔等的驱动程序是传入的单位。在上光中的活动是维修、人工上光、在制品转移、返工、箱子振动、规划、例行控制和棱镜数据输入。维修的驱动程序是返工零件的数量,人工上光的驱动程序是釉面部分的重量,在制品转移和返工的驱动程序是返工零部件的数量,箱子振动的驱动程序是箱子的数量,规划、例行控制和棱镜数据输入的驱动程序是计划的单位。隧道烤箱部门开展的活动是隧道烤箱活动,转到烤箱,再从烤箱转出,热控制,烤箱安全控制,规划,例行控制,棱镜数据输入,记录,第二次热处理,在制品投入到烤箱,热处理过的单位和特殊处理的返工。隧道烤箱、转移到烤箱、又从烤箱转出、热控制和烤箱安全控制的驱动程序是受热单位覆盖的总面积,规划、例行控制、棱镜数据并且录入的驱动程
