如何设计金属冲压件:10条DFM规则,降低40%模具成本
如何设计金属冲压件:10条DFM规则,降低40%模具成本

金属冲压件设计的直接答案是优先考虑均匀壁厚、充足的折弯半径和标准孔径,同时避免低于±0.1 mm的严格公差。遵循这些可制造性设计(DFM)规则,可将模具制造成本降低30-40%,并在BQUQ东莞工厂将交货周期从6周缩短至3周。本文提供可直接影响冲压件定价和模具寿命的量化DFM阈值。材料选择与厚度限制材料选择决定冲压速度...

如何检验冲压件:精密制造中的关键尺寸与质量检查
如何检验冲压件:精密制造中的关键尺寸与质量检查

在精密金属冲压中,检验并非最终关卡,而是一个持续反馈回路,它控制着模具磨损、材料一致性以及冲床稳定性。关于如何检验冲压件,最直接的答案是:使用经过校准的工具验证关键功能(CTF)尺寸,验证材料硬度和表面完整性,并将结果与源自首件检验(FAI)的统计过程控制(SPC)基线进行比较。对于厚度为0.5毫米的不锈钢零件,这意味...

电触点和端子:精密冲压如何确保长期可靠性
电触点和端子:精密冲压如何确保长期可靠性

精密冲压是电触点和端子制造的最终工艺,因为它能实现微米级的尺寸重复性、优异的表面光洁度以及加工或制造等替代方法无法比拟的高性价比。通过控制材料晶粒流向并将公差保持在±0.01 mm以内,冲压可确保数百万次循环中一致的接触压力、最小的电阻和可预测的热性能。本文提供了为关键任务应用指定冲压触点所需的工程数据和工艺参数。材料...

冲压模具成本:2025年按模具类型划分的价格明细
冲压模具成本:2025年按模具类型划分的价格明细

简短的回答是:一套冲压模具的价格从简单下料模具的800美元到用于汽车零部件的高速级进模的150,000美元不等。在中国工厂(如BQUQ)进行的典型精密金属冲压项目中,模具的中位价格在5,000至30,000美元之间,具体取决于零件尺寸、材料厚度和年产量。本文根据我们东莞工厂20年的制造数据,详细解析了确切的成本驱动因素...

级进模冲压与深拉延冲压:关键差异详解
级进模冲压与深拉延冲压:关键差异详解

级进模冲压和深拉深冲压都是大批量金属成型工艺,但它们的根本用途截然不同。级进模冲压通过在一个冲压行程中经过一系列工位,将平板金属切割并成型为成品零件;而深拉深冲压则利用拉应力和压应力将金属板料拉入模具型腔,形成三维中空形状,例如杯形件或筒形件。主要区别在于几何结果:级进模生产平面或弯曲件,而深拉深模具生产无缝、中空且深...
