开篇

您的图纸决定弹簧的规格,我们严格按照图纸制造。每一件定制拉伸弹簧均根据您的CAD文件、PDF图纸或实物样品生产。发货前,我们会验证尺寸和载荷,绝无猜测。

我们在中国东莞经营一家拥有20年历史的精密制造工厂。弹簧生产线与CNC加工线和冲压线完全独立,这意味着您的零件由专用设备、专用模具和专属质检团队负责。

  • 公差:线径±0.05 mm,自由长度±0.1 mm
  • 交期:打样7–12天,批量生产15–20天
  • 无起订量——可订购10件或100,000件
  • 镀锌层:厚度8–12 µm,盐雾试验至少48小时
  • 每批次附带材质证书和完整检验报告

材质牌号SWP-B、302/304/316不锈钢、65Mn、60Si2MnA可按炉号提供材质证明
设备CNC卷簧机、自动弹簧成型机、拉簧钩环折弯机重复精度可达0.02 mm
检验关键尺寸100%全检,载荷按批次抽样每批次提供检验报告
批次追溯炉号、设备编号、操作员编号、日期标注于标签可完整追溯至原材料

定制铜质螺旋天线弹簧

镀锌工序不外包,全部在厂内完成。您只需对接一个供应商、执行一个质量标准、接收一次交货。

客户将图纸交给我们的三大理由

1. 批次可追溯的质量。 每件弹簧都有批次号,该编号关联到原材料炉号、卷簧设备、操作员和镀锌槽。如果您的装配线上出现问题,我们几分钟内即可追溯到位,而不是几天。您将获得一份书面记录,存档于您的QA文件中。

2. 每批次附检验报告。 我们不只是说“没问题”。您会收到一份PDF报告,包含实测尺寸、载荷测试结果、表面质量检查和盐雾试验数据。报告由我们的质检主管签字。如需第三方检测(SGS、BV),我们也可协调安排。

3. 一家工厂搞定CNC、冲压、弹簧和散热器。 您的弹簧通常与冲压支架或CNC加工壳体配合使用。将整个组件发给我们,所有零件在同一厂房屋顶下完成制造。这消除了公差累积问题,也减少了供应商管理时间。一张采购订单、一次交货、一个责任方。

应用领域

镀锌拉伸弹簧不是装饰件,它们承担着实实在在的工作。以下是我们每月实际发货的应用场景:

  • 汽车行业: 制动踏板回位弹簧、离合器联动弹簧、锁止机构。镀锌层可抵抗路盐和湿气腐蚀。
  • 工业设备: 输送带张紧器、配重平衡系统、开门机。需要在数千次循环中保持稳定的载荷。
  • 医疗器械: 器械回位弹簧、可调床机构。此类产品我们使用302不锈钢,但采用相同的工装和质检标准。
  • 农业机械: 播种机机构、打捆机张紧弹簧。面对粉尘和潮湿环境——镀锌是标准选择。
  • 消费产品: 蹦床弹簧、车库门张紧弹簧、健身器材。要求高循环寿命和稳定的拉力。

如果您的应用需要在特定长度下达到特定载荷,我们会根据您的需求计算线径和圈数。您无需自行估算。发送图纸或工作空间尺寸,我们为您设计弹簧。

客户下单前常问的问题

问:起订量是多少? 零。没有最低起订量。我们在同一台设备上生产10件打样和100,000件批量订单。大批量订单的模具费用摊入单价;小批量订单仅收取少量装调费。仅此而已。

问:如何控制公差和质量? 我们对100%的零件进行自由长度、外径和钩环角度测量。载荷测试按每批次5%抽样进行,如果您要求,也可以100%全检。我们的CNC卷簧机线径进给精度保持在±0.05 mm。镀锌层厚度使用数显测厚仪验证。您将收到完整报告。

问:交期是多久? 图纸确认后,打样弹簧7–12天发货。批量订单15–20天发货。对于无设计变更的返单,我们可以备安全库存,5天内发货。从我们工厂到您处的空运时间为3–5天,视目的地而定。

问:能否提供材质证书? 可以。每批次均附带原材料线材的钢厂证书,显示化学成分和力学性能。我们还提供镀锌证书,包含厚度和盐雾试验结果。如果您的客户有要求,我们还可以为“中国制造”产品提供公证的原产地证书。

发送您的图纸

不要凭空设计。将您的弹簧图纸、草图甚至实物样品发给我们。我们将进行逆向工程,确认载荷和尺寸,并在12小时内给出正式报价。

邮箱:sc@bquq.com WhatsApp:+86 13713157787

我们在一个工作小时内回复。没有销售话术,只有工程解答。您的图纸在我们这里安全无忧——我们可按要求签署保密协议(NDA)。精密制造是我们的核心,定制弹簧是我们的专长,当质检做到如此严格时,“中国制造”绝不是妥协。
