金属冲压如何生产家电外壳、支架和结构件?
金属冲压如何生产家电外壳、支架和结构件?

金属冲压是家电外壳、支架和结构件最具成本效益且可重复性最高的制造工艺,能够以每分钟20至60次冲程的节拍从金属卷料生产零部件。对于大批量家电生产(年产量超过10,000件),冲压件关键特征公差可达±0.05 mm,成本比CNC加工同等零件低30%至70%。本文基于BQUQ在东莞二十年的生产数据,详细阐述决定家电级冲压成...

如何估算金属冲压价格:模具、零件成本与最小起订量详解
如何估算金属冲压价格:模具、零件成本与最小起订量详解

估算金属冲压价格需要区分三个独立的成本驱动因素:模具费(一次性模具制造)、单件价格(每件材料与加工费)以及最小起订量(MOQ)分摊。一般来说,简单落料模的模具费起价为800美元,而复杂零件的级进模则需8,000至50,000美元;单件价格通常在0.05至2.00美元之间,具体取决于材料厚度和公差。本文将详细拆解精确公式...

金属冲压如何延长电池触点和弹簧夹的使用寿命?
金属冲压如何延长电池触点和弹簧夹的使用寿命?

直接的回答是,金属冲压通过使用高强度、耐腐蚀的合金,并利用其精确的晶粒流向和加工硬化特性,从而延长电池触点和弹簧夹的寿命,这些特性是机加工或铸造无法实现的。该工艺能够生产具有严格公差(低至±0.01毫米)和特定表面光洁度的部件,从而降低电阻和机械磨损。通过将级进模设计与先进的材料科学相结合,冲压制造出能够抵抗疲劳和环境...

哪些材料可以进行金属冲压?完整指南
哪些材料可以进行金属冲压?完整指南

金属冲压可加工超过40种不同的铁基和非铁基合金,但最常见的材料是低碳钢、不锈钢(304和301牌号)、铝(5000和6000系列)、黄铜和铜。材料选择取决于所需的抗拉强度、耐腐蚀性、导电性和每公斤成本,原材料价格从热轧钢的1.20美元/公斤到316不锈钢的8.50美元/公斤不等。在BQUQ,我们冲压过从0.05毫米箔材...

冲压与深拉延有何区别?工艺对比指南
冲压与深拉延有何区别?工艺对比指南

冲压和深拉伸都是钣金成型工艺,但它们的根本目的不同:冲压利用高作用力将平板金属切割、弯曲或冲孔成特定形状,而深拉伸则利用拉伸力和压缩力将金属板拉入三维中空型腔。具体来说,冲压生产扁平或浅成型的零件,如支架和垫圈;而深拉伸生产无缝的杯形或盒形部件,如电池壳和水槽盆。关键区别在于材料流动:冲压依赖于剪切和变形,没有显著的材...
