开场

我们严格按照您的图纸制造双扭簧。不是近似品,不是“差不多”的版本。您的DWG或PDF文件定义了线径、圈数、腿角度和自由位置。我们严格遵循。

每根弹簧在发货前都经过验证。我们检查线圈直径、腿位置以及指定挠度下的载荷。如果与您的图纸不符,则不会发货。

概览: 线圈外径公差±0.05毫米,腿角度公差±1°,交货期7-12个工作日,无起订量,包含材质证书。

文件材质证书(EN 10204 3.1)、尺寸报告、载荷测试报告

定制铜质螺旋天线弹簧

我们使用CNC卷簧机,而非手工卷绕设备。这确保了整个批次中螺距和腿几何形状的一致性。对于关键应用,我们增加喷丸处理,可将疲劳寿命提高多达30%。

买家向我们发送图纸的三个理由

1. 批次可追溯的质量。 每个生产批次都有唯一的炉号和工单号。如果您需要将弹簧追溯到其线材批次,我们可以在几分钟内完成。我们保存记录长达10年。

2. 每批次检验报告。 您将获得包含实际测量值的尺寸报告,而不仅仅是合格/不合格的盖章。我们测量线圈外径、自由长度、腿角度以及两个指定挠度下的载荷。报告由我们的质检工程师签署。

3. 同一工厂完成CNC加工+冲压+弹簧+散热器。 您的组件可能需要冲压支架、CNC加工外壳、压缩弹簧和铝制散热器。我们在同一厂房内制造全部四种部件。您节省了运输费用,节省了供应商管理成本,并且整个组件只需对接一个责任方。

这些零件的应用领域

双扭簧储存能量并将机构恢复到起始位置。它们常见于:

  • 汽车 – 安全带卷收器、节气门回位机构、离合器踏板
  • 医疗器械 – 手术缝合器、可伸缩针头、骨科支具
  • 航空航天 – 执行器回位弹簧、客舱内部闩锁机构
  • 工业设备 – 安全阀、输送带张紧器、闭门器
  • 消费品 – 衣夹、捕鼠器、折叠家具铰链、车库门配重

由于我们控制线材材料和热处理工艺,我们可以将弹簧刚度精确调整到您的应用需求。需要一根在30°挠度下保持5N力的弹簧?我们计算线径和圈数,然后在载荷测试仪上进行验证。

买家在下单前常问的问题

问:你们的最小起订量是多少? 答:没有最小起订量。我们可以制作一件原型或一百万件产品。原型单价略高,但模具免费。对于标准线径,我们不收取设置费。

问:你们如何保证公差和质量? 答:我们使用带闭环送线控制的CNC卷簧机。首件在三坐标测量机和扭力载荷测试仪上测量。生产批次按AQL 2.5抽检。如果尺寸出现偏差,我们会停机调整。您将随货收到检验报告。

问:定制弹簧的交货期是多久? 答:原型:5-7个工作日。生产:图纸确认后7-12个工作日。对于紧急订单,我们可以加急48小时内交付原型,需加收20%费用。

问:你们能提供材质证书吗? 答:可以。每批次均附带EN 10204 3.1材质证书。如有要求,我们还可提供硬度测试报告和疲劳测试数据。对于航空航天或医疗应用,我们可以提供完整的可追溯性文件。

发送您的图纸

通过电子邮件发送您的DWG、DXF、PDF文件,甚至带尺寸的手绘草图。我们的工程师将进行审核,并在12小时内向您发送正式报价。报价包括单价、模具费用(如有)、交货期,以及如果您的图纸未指定材料时的建议材料。

我们是中国东莞的一家精密制造工厂,拥有20年的弹簧制造经验。您直接与工程师沟通,而非销售人员。
