如何设计金属冲压零件:10条可制造性规则
如何设计金属冲压零件:10条可制造性规则

为金属冲压设计零件与为机加工或3D打印设计有着根本性的不同。直接的答案是,你必须为一种使用硬质模具对金属板材进行大批量切割和成型的工艺进行设计,这意味着你的零件几何形状必须适应恒定的材料厚度、特定的弯曲半径和脱模斜度。遵循10条核心设计规则——涵盖材料选择、弯曲余量、孔位布局和公差预算——可将模具成本降低高达30%,并...

定制金属冲压件的最低起订量(MOQ)是多少?
定制金属冲压件的最低起订量(MOQ)是多少?

定制金属冲压件的最小起订量(MOQ)通常为:简单平面毛坯件500至5,000件,而级进模冲压项目通常需要10,000至50,000件才能有效分摊模具成本。在BQUQ,我们将直径小于50毫米的零件的标准MOQ设定为1,000件,但使用软模进行原型验证时,我们接受低至500件的订单。您的实际MOQ取决于材料厚度、零件复杂度...

冲压与激光切割:您应选择哪种钣金工艺?
冲压与激光切割:您应选择哪种钣金工艺?

对于产量超过1,000件的生产,冲压是成本更低、速度更快的选择,而激光切割则更适用于原型制作、复杂几何形状以及500件以下的产量。冲压的单件成本在大批量生产时可降至$0.15-$0.50,但需要投入$3,000-$50,000的模具费用;而激光切割无需模具成本,但单件费用稳定在$2-$15。决策的关键在于您的年产量、所...

金属冲压公差能达到怎样的精度?
金属冲压公差能达到怎样的精度?

对于标准金属冲压,您可以预期落料和成型工序的尺寸公差为 ±0.1 毫米(0.004 英寸),而精密精冲可达到 ±0.01 毫米(0.0004 英寸)。该范围取决于材料厚度、模具质量和冲压速度,我们东莞工厂在级进模作业中通常能将公差控制在 ±0.05 毫米。您能达到的精确精度取决于冲压方法、零件几何形状和批量,而非行业统...

金属冲压中渐进式模具设计的核心原则是什么?
金属冲压中渐进式模具设计的核心原则是什么?

金属冲压级进模设计的核心在于将落料、冲孔、弯曲、拉深等工序有序地编排到一条连续送进的料带上,每个工位逐步对零件进行成形,直至最终冲出完整零件。其基本原则是保持恒定的料带宽度和步距,同时确保材料在各工位之间保持平整和可控,关键尺寸的典型公差可达±0.05毫米。一个成功的级进模设计需要在模具成本、生产速度(通常为每分钟20...
