精密触摸屏弹簧触点

我们采用带伺服控制螺距的CNC卷簧机,确保每批次几何形状的一致性。对于铜合金,我们调整卷制速度以防止加工硬化。去应力退火在可控气氛炉中进行,消除残余应力并稳定扭矩。

客户选择向我们发送图纸的三个理由

1. 批次可追溯质量。 每批次都有唯一的热处理炉号和生产线批号。材料可追溯至钢厂质保书。如果您的现场出现问题,我们可以精确定位到具体批次和生产日期。这对我们来说是标准流程,而非额外服务。

2. 每批次检验报告。 每次发货均附带尺寸检测报告,列明线径、外径、自由长度、总圈数和角变形量。扭矩在您指定的偏转角度下测量。报告由我们的QC工程师签字,您可将其归档至自己的QA记录中。

3. 同一工厂完成CNC加工、冲压、弹簧和散热器。 您的组件可能需要冲压支架、CNC加工轴和弹簧。我们在同一厂区内全部完成。您只需对接一位工程师、一套质量体系、一张发货发票。这减少了供应商管理时间,并降低了零件间的公差累积问题。

应用领域

铜扣轴扭簧并非通用零件,它们应用于特定且要求严苛的场景。

  • 汽车安全带锁扣。 弹簧为释放按钮提供回弹扭矩,循环寿命达数万次。铜合金在零件整个寿命期内保持扭矩一致性。
  • 笔记本电脑铰链机构。 小型扭簧将屏幕固定在设定角度。铜材料可抵抗反复开合造成的疲劳。
  • 电气开关设备。 断路器中的扭簧储存能量以实现快速脱扣。铜的导电性在载流路径中是一大优势。
  • 医疗器械夹钳。 需要夹持和释放的器械要求可预测的扭矩。我们的弹簧在整个量产过程中保持公差稳定。
  • 消费电子产品。 相机镜头筒和SIM卡弹出器使用微型扭簧。对于这些微小零件,我们将线径公差控制在±0.05 mm以内。

如果您的应用需要弹簧在负载下回到精确角度,本系列产品正合适。

客户下单前常见问题

问:你们的起订量是多少? 答:无起订量。我们可以制作一件样品,也可以生产一百万件。单价随数量递减,但我们从不拒绝小批量订单。打样价格透明且固定。

问:你们如何控制公差和质量? 答:我们使用带数字读数的CNC卷簧机。每个弹簧均通过光学投影仪或CNC坐标测量机进行检测。扭矩在弹簧测试机上按您指定的角度进行验证。检验报告存档保留两年。

问:量产交期是多久? 答:打样7天发货。图纸确认后,量产15天发货。紧急订单可加急至5天出样。您发送图纸后,我们会给出确切交期。

问:你们能提供材料证书吗? 答:可以。我们提供铜及铜合金的钢厂质保书,包含化学成分和力学性能。每笔量产订单均免费附带证书。
