精密钢制扭簧系列

所有弹簧均在中国东莞工厂生产。我们拥有12台CNC卷簧机、4台热处理炉和2个自动检测工位。标准铜合金日产能为50,000件。

客户选择向我们发送图纸的三个理由

1. 批次可追溯的质量。 每批产品都有唯一批次号,该编号关联材料证书、机器参数、热处理记录和检测结果。如果您的装配线上出现问题,我们可以在几分钟内追溯到具体的卷簧机和操作员。

2. 每批附检测报告。 我们不只是说“质量没问题”。您会收到纸质和电子版报告,显示线径、自由长度、外径、圈数以及指定变形量下的载荷实测值。对于射频应用,我们还使用四线开尔文夹具测量接触电阻。

3. 同一工厂完成CNC加工+冲压+弹簧+散热器。 您的天线弹簧可能旁边就是冲压触点或CNC加工外壳。我们在同一厂房内完成所有生产。这意味着只需一张采购订单、一套质量体系、一个发货日期。您节省了物流成本,也避免了不同供应商之间的公差不匹配问题。

这些零件的应用场景

铜质螺旋天线弹簧不是装饰件。它们同时承载射频信号和机械载荷。典型应用包括:

  • 物联网模块 – 用于2.4 GHz和5 GHz频段的PCB天线弹簧加载触点
  • 汽车遥控钥匙 – 用于电池端子和天线馈电的螺旋接触弹簧
  • 医疗遥测设备 – 可穿戴心电图和血糖监测仪中的小型铜弹簧
  • 基站天线 – 用于移相器触点的压缩弹簧
  • 测试插座 – 用于半导体封装射频测试的弹簧探针
  • 消费电子 – 笔记本电脑Wi-Fi天线、耳机充电触点

在每种应用中,弹簧必须在数千次循环中提供稳定的接触力。铜合金具有低电阻率(1.7–6.0 µΩ·cm)和良好的疲劳寿命。我们通过调整线径、圈数和自由长度来改变弹簧刚度——全部按您的图纸执行。

客户下单前常问的问题

问:你们真的没有最小起订量吗? 答:是的。我们接受1–10件的打样订单,公差与量产完全一致。唯一区别是单价。由于采用CNC工艺,无需专用模具费用。

问:你们如何控制公差和质量? 答:我们使用带伺服驱动送线机构的CNC卷簧机。卷制后,每根弹簧通过光学测量系统检测外径、自由长度和螺距。对于关键尺寸,我们使用分辨率0.001 mm的三坐标测量机。每批出货均附检测报告。

问:定制铜弹簧的交期是多久? 答:打样:图纸确认后7–12天。量产:15–20天,视数量和表面处理而定。如有紧急需求,标准铜合金可提供48小时加急打样服务。

问:你们能提供材料证书吗? 答:可以。我们提供铜合金批次的钢厂检测证书,包括化学成分和力学性能。对于航空航天或医疗订单,我们还可提供至原始铸锭的全流程追溯。
