开篇

将您的图纸发送给我们。我们根据规格制造您的拉伸弹簧,而非凭空猜测。

每一圈线圈均在我们自己的生产线上完成卷制、热处理和去应力处理。发货前,我们会验证指定长度下的载荷、自由长度和外径。若与您的图纸不符,则不予发货。

我们是一家位于中国东莞的精密制造工厂,拥有20年行业经验。集CNC加工、金属冲压、弹簧和散热器于一体。您直接与工程师沟通,而非面对销售话术。

  • 公差:线径和自由长度 ±0.05 mm(DIN 2095 2级)
  • 交期:样品 7–12 天,量产 15–20 天
  • 无最小起订量。无论一件还是一百万件,图纸审核流程相同。

中国定制双扭簧制造

我们采用日本和德国卷簧机。线材仅采购自认证钢厂。每批材料均有炉号,我们保留该追溯记录长达10年。

客户向我们发送图纸的三大理由

1. 批次可追溯的品质,而非碰运气。 每炉线材均有记录。每个生产批次都有唯一编号。如果零件在您的装配中失效,我们可以追溯到线材供应商、卷簧机和操作班组。我们这样做,是因为我们的品质始于您的责任止步之处。

2. 每批次均附检测报告。 您将获得尺寸报告和载荷测试报告。我们测量自由长度、外径以及您指定变形量下的载荷。对于关键弹簧,我们额外进行100%载荷分选。标准报告不收取额外费用。在货物离厂之前,您已确切知晓所收到的产品。

3. 同一工厂完成CNC加工、冲压、弹簧和散热器。 您的弹簧不是孤立的零件。我们加工支架、冲压固定件,甚至制造弹簧所安装的散热器。一张采购订单、一套质量体系、一个发货日期。您节省物流成本,并消除不同供应商之间的公差累积。

应用领域

这些不是玩具弹簧。我们的客户将其应用于:

  • 汽车 – 离合器回位弹簧、制动踏板回位弹簧、节气门拉杆、安全带卷收器
  • 医疗器械 – 手术器械回位、导管输送系统、骨科张紧器
  • 航空航天 – 执行器回位弹簧、闩锁机构、无磁应用(17-7PH)
  • 工业设备 – 输送带张紧器、阀门回位、弹簧加载密封件
  • 电气外壳 – 接地夹、门锁、电池接触弹片
  • 消费电器 – 洗衣机门锁、烤面包机机构、吸尘器滚刷

如果您的弹簧失效,您的产品就会停机。我们制造的弹簧至少可承受100,000次循环,如果您指定循环要求,我们也会按此进行测试。

客户下单前常问的问题

问:你们的最小起订量是多少? 无最小起订量。我们先制作一件样品供您测试,然后批量生产。样品交期7天,通过DHL或FedEx发货。批量生产时,我们会分批交付,以保持您的库存灵活性。

问:你们如何控制公差和品质? 我们以DIN 2095为基准。对于关键尺寸,我们使用载荷传感器精度为±0.5%的CNC弹簧测试仪。每个批次均经过首件检验、过程检验和最终检验。首件样品保留24个月。如需PPAP 3级文件,我们可提供。

问:定制弹簧的交期是多久? 样品:图纸确认后 7–12 天。量产:标准不锈钢 15–20 天。紧急订单,样品可加急至5天,需加收15%费用。下单前我们会告知您确切日期。

问:你们能提供材质证明吗? 可以。我们提供不锈钢线材的EN 10204 3.1钢厂质保书,同时提供我们自己的热处理记录和硬度测试报告。所有文件均为英文,随货发送。

发送您的图纸

不要再猜测了。将您的PDF、STEP或IGES文件发送给我们。我们进行可制造性审核,并在12小时内给您正式报价。
