(1) 铸造流程(OEM方式承接铸造):
客户来图来样→审核评估与报价并与客户沟通→签订业务合同→工程绘制铸件图纸→客户确认图纸→设计并制造射蜡模具→样板制作→客户确认铸件样板→样板合格(如不合格修正模具再做样板直至合格)→客户下单→生产计划→射蜡→制壳→熔铸→碎壳→切割→磨水口→酸洗→滚抛→检验→不合格铸件返修→合格品包装→合格品出货(废品回炉)
(2) 生产周期(OEM方式承接铸造);
客户来图来样 审核报价并与客户沟通 1天
工程绘制铸件图纸 1~3天 (以图纸难度大小而定)
制作射蜡模具 2~9天 (以样板难度大小而定)
样板制作3~10天 (以样板难度大小而定)
订购单7~35天 (以当月生产情况和订购单数量而定)
(3 )铸造范围限定:
铸件重量5克~40公斤。
铸件壁厚>1.8mm,局部可以最小0.5mm。
铸件轮廓尺寸>450mm。表面粗糙度为1.6~6.4
