Engineering & production / Co-founder’s point of view

Copy the quotations and see six items clearly

For two parts with similar dimensions, the copying workload may be very different. When comparing quotes, put acquisition, modeling, accuracy, delivery, verification and field conditions on the same list rather than just comparing a total price.

How much is charged for reverse copying? Six factors that affect quotations

Let’s look at the conclusion first

  • Size is not the only basis for pricing, complexity and usage are more important.
  • Accuracy requirements should be implemented into specific locations and acceptance methods.
  • Write inclusions, exclusions, and scope of modifications into the quote.

Factors 1 and 2: shape and site conditions

规则平面和复杂自由曲面,需要的处理方法不同;深腔、薄壁、反光或柔性表面,也会影响采集准备。大型部件可能涉及搬运、定位和多次采集,不能仅按长宽高简单比较。

现场是否能拆卸、有没有操作空间、是否需要上门,以及样件是否完整,都会影响工作安排。提供多角度照片和基础尺寸,可以帮助我们先判断任务范围;无法从照片确认的事项,应在报价中列明。

Factor 3: Accuracy requirements and inspection location

“越精准越好”不是可执行的验收要求。外观参考面、安装孔、配合轴和装配基准的重要程度不同,应分别说明目标与用途,让投入集中在真正影响后续使用的位置。

设备标称参数也不等于每个零件、每个位置的最终交付结果。采集条件、模型重建、测量基准和复核方法都需要考虑。报价应约定可检查的关键项目,而不是只写一个没有适用条件的精度数字。

Factor 4: Which step to deliver to?

只交扫描网格,与交付曲面、实体、工程图或改型设计,是不同工作范围。客户如果希望后续开模、加工或改结构,应在询价时说明,不要到交付后才发现需要追加重建。

建议报价单区分采集、数据整理、模型重建、改型与出图,并注明格式及版本。即使采用打包报价,也要明确交付物,让不同供应商的报价具备可比性。

04 / Engineering & production

Factors five and six: verification and modification scope

是否需要关键尺寸报告、偏差比对、样件回装或手板验证,会影响工时安排。客户要求的交期、修改轮次和后续设计变更,也应与原始任务区分。

例如,纠正已确认范围内的建模问题,与客户改变产品用途后新增结构,并不是同一类修改。把这部分说清楚,不是增加沟通门槛,而是让双方在交付过程中有一致预期。

Before making an inquiry, prepare a brief information

可以先提供样件照片、尺寸范围、数量、关键位置、用途、文件格式和目标时间。资料暂时不完整也可以沟通,但应把不确定项保留下来,待实物检查后再确认。

本文不发布脱离条件的统一价目。我们更希望客户拿到的是能够执行的工作范围与报价依据,而不是看起来很低、后续却不断增加必要工序的数字。

Co-founder suggestions/What to do next

Before comparing quotes, compare whether they are doing the same thing. Price comparisons only make sense if scope, delivery and acceptance are consistent.
