产品详情

这是一项定制金属冲压服务,适用于弹片触点、弹簧夹和精密支架——在我们的东莞工厂生产。您将获得公差为±0.01 mm的冲压件、标准15天交期,以及根据材料和热处理不同而变化的HV 200–500硬度范围。这是中国制造的精密加工,没有通常的最低起订量门槛。

弹片触点的冲压公差与重复性

我们的高速冲床(25至200吨)在模具制造阶段保持±0.005 mm的模具公差,生产零件的关键尺寸公差为±0.01 mm。对于必须保持稳定挠曲的弹片臂,我们将弯曲半径控制在±0.03 mm以内。这确保了接触力在100万次循环内保持在设计值的5%以内。我们使用三坐标测量机和2.5D光学投影仪测量每个关键尺寸——每批产品均附带检测报告。

弹簧弹片的材料与硬度选项

我们常备304和301不锈钢、C17200铍铜、磷青铜(C5210)以及SPCC/SECC冷轧钢板。对于必须在高温或反复弯曲环境下工作的弹片,我们推荐全硬状态的301不锈钢(HV 480–520)。铍铜提供HV 360–420的硬度,并具有优异的导电性。如果您需要更柔软的触感,我们可在冲压后进行退火处理至HV 200–250。原材料厚度范围为0.05 mm至6.0 mm,最大零件尺寸为500 mm × 300 mm。

二次加工:热处理、电镀与成型

仅靠冲压通常不足以完成弹片的最终制造。我们在真空炉中进行去应力退火,以防止回弹漂移。在表面处理方面,我们提供镀镍(2–5 µm)、闪金(0.5–1 µm)和镀锡(用于可焊性)。我们的内部线切割和CNC铣削可处理任何无法一次冲压成型的后冲压特征,如槽孔或通孔。我们还提供压印工艺,将关键表面平整度控制在10 mm长度内0.02 mm以内。

模具与模具寿命实现低成本生产

对于级进模,我们在磨损区域使用碳化钨镶件——这可在重新刃磨前实现1000–1500万次冲程。对于小批量原型,我们使用简化的冲头-凹模模具,模具成本为$800–$1,500,交期为5–7天。这是测试您的弹片设计而无需投入全套生产模具的最快方式。当您准备批量生产时,我们将模具成本分摊到单价中——订单超过100,000件时无需预付模具费。

质量控制与检测报告

每批产品在生产前都会进行首件检验(FAI)。我们对每个弹片检查4个项目:材料厚度、弯曲角度、表面粗糙度(Ra 0.4–0.8 µm)和接触力(使用测力传感器测量)。冲压线上每30分钟进行一次过程检验。我们随每批货物提供PDF或Excel格式的完整尺寸报告。对于汽车或医疗客户,我们可免费提供PPAP Level 3文件。

东莞工厂的包装、物流与出口

零件采用防锈VCI纸包装,然后放入瓦楞纸箱或定制托盘,以防止运输过程中弯曲。标准出口包装在质检后24小时内完成。从我们的东莞工厂出发,空运至美国西海岸需3–5天;海运至汉堡或洛杉矶需18–25天。我们处理所有出口文件,包括原产地证、自贸协定证书和商业发票。对于紧急订单,我们可在图纸批准后48小时内通过DHL快递发出500件样品批次。

成本构成与无起订量政策

以下是透明的定价结构:模具费与单件价格分开计算。对于简单弹片(2个弯折、1个孔),50,000件时单件价格为$0.02–$0.08。在500,000件时,价格降至$0.01–$0.03。我们不设最低起订量——您可以订购100件用于测试,单价略高。这一无起订量政策让您可以在扩大规模之前使用真实生产模具验证您的设计。我们还为有定期交货计划的年度总订单提供3%的折扣。

常见问题:弹片设计与冲压限制

弹片不产生裂纹的最小弯曲半径是多少?

对于半硬状态的301不锈钢,最小弯曲半径为材料厚度的1倍;对于铍铜,为厚度的0.5倍。

你们能冲压厚度低于0.1 mm的弹片吗?

可以,我们经常冲压0.05 mm的磷青铜用于接触弹簧,但我们建议进行去应力退火以防止边缘断裂。

如何控制复杂3弯弹片的回弹?

我们在模具中过弯2–5度,然后在弯曲线处使用压印工艺将最终角度控制在±0.5度以内。

小批量测试订单的最快运输方式是什么?

DHL快递从东莞到大多数国家需要2–4天;我们在图纸批准后48小时内发货500件或更少。
