开篇

我们根据您的图纸制造不锈钢螺旋压缩弹簧,而非按目录选型。您发送文件,我们切割线材、磨平端部、设定载荷。每根弹簧在发货前均经过测量。若不符合您的图纸要求,您无需付款。

概览: 线径公差 ±0.02 mm,自由长度公差 ±0.05 mm。样品交期 7–10 天,量产交期 15–20 天。无起订量。所有弹簧均在我司东莞工厂制造,每批次附完整检验报告。

定制铜质螺旋天线弹簧

买家选择发送图纸给我们三大理由

1. 批次可追溯质量。 每批次分配唯一批号。我们记录线材炉号、设备参数和操作员编号。若您的装配线上出现任何问题,可精确追溯至具体卷簧及生产时段。每批货物均附带完整追溯报告。

2. 每批次检验报告。 我们不仅依赖最终单次检查。卷绕完成后,我们从每批次中抽取样品测量自由长度、外径和线径。随后对 5% 的零件进行载荷测试,验证弹簧刚度和密实高度。您将收到一份签字的检验报告,包含实际测量值,而非仅通过/不通过的盖章。

3. 同一工厂完成 CNC + 冲压 + 弹簧 + 散热器。 您的压缩弹簧通常与冲压支架、CNC 加工外壳或散热器配套使用。无需协调三家供应商,您只需将整个组件发给我们。我们在厂内完成所有零件制造、组装,并以单一 SKU 发货。这可将交期缩短 2–3 周,并消除供应商之间的公差累积问题。

应用领域

定制不锈钢压缩弹簧适用于碳钢易腐蚀或疲劳过快的严苛环境。

  • 医疗器械: 胰岛素笔、手术吻合器、药物输送泵。此类弹簧需要严格的载荷公差和生物相容性表面。
  • 汽车行业: 燃油喷射器、气门回位弹簧、制动系统部件。我们选用 SUS316 或 17-7PH 以提供耐高温和耐腐蚀性能。
  • 航空航天: 执行器、起落架锁、舱压阀。弹簧必须通过 100% 裂纹检测,并在 100 万次循环后保持载荷。
  • 电子行业: 电池触点、开关机构、连接器引脚。最小线径可达 0.10 mm,在数千次循环中保持稳定的弹力。
  • 工业设备: 安全阀、减压阀、离合器机构。弹簧常在油液或蒸汽环境中运行,因此我们指定钝化表面处理。

买家常见问题

问:真的没有起订量吗? 答:是的。如果您只需要一件样品弹簧,我们就为您生产一件。量产时,我们根据线径和复杂程度按件计价。单价随数量增加而降低,但您绝不会被要求订购超出项目需求的量。

问:如何保证公差和质量? 答:我们使用经校准的数显卡尺和载荷测试机对每批次进行测量。我们的线径公差 ±0.02 mm 严于 DIN 2095 标准。在批量生产前,我们还会随检验报告发送样品供您确认,让您批准的是实际零件,而非图纸。

问:典型交期是多久? 答:样品在图纸确认后 7–10 个工作日内发货。量产需要 15–20 个工作日。如需加急,我们可将订单分批交付——首批 20% 在 5 天内发出,其余在 10 天内发出。

问:能否提供材质证明? 答:可以。每批弹簧均附带线材厂出具的材质证明,显示炉号、化学成分和力学性能。我们还可根据要求提供 RoHS 和 REACH 合规声明。
