您的图纸决定弹簧。我们精确制造。

每一根弹簧都严格按照您的图纸生产——线径、自由长度、总圈数、指定变形量下的载荷以及端部形式。发货前我们逐项核验每个尺寸。绝无含糊。

  • 公差:外径和自由长度 ±0.05 mm(依据 DIN 2095 二级精度)
  • 交期:打样 7–12 个工作日,批量生产 15–20 个工作日
  • 无起订量——可订一件,也可订一百万件
  • 材质证书:每批次均附带 EN 10204 3.1 证书

我们是一家位于中国东莞的精密制造工厂,拥有 20 年 CNC 加工、金属冲压、弹簧及散热器制造经验。同一车间、同一质量体系、同一张发票。

规格参数

批次管控炉号可追溯,每箱均加盖批次号
包装防锈纸、独立塑料袋、出口纸箱

定制螺旋弹簧天线线圈

所有弹簧在卷绕后均经过去应力处理。喷丸为可选工艺,但建议用于 10⁷ 次以上循环载荷的工况。按行业惯例,我们以压并高度的 20% 作为载荷设定点。

采购方选择将图纸交给我们的三大理由

1. 批次可追溯的质量。 每批产品都有唯一编号,该编号关联到材料炉号、卷绕设备、操作人员及检验记录。如果零件在您的装配中出现问题,我们可在几分钟内追溯到具体的线材批次。这在大多数中国弹簧厂并不常见。

2. 每批附检验报告。 每次发货您都会收到一份尺寸报告,列出抽样零件的内外径、自由长度、压并高度及指定变形量下的载荷。我们还随附材质证书和硬度测试结果,不另收费。

3. 同一工厂完成 CNC + 冲压 + 弹簧 + 散热器。 您的组件可能需要冲压支架、CNC 加工外壳和弹簧。我们可在同一厂区内全部完成。您只需一张采购订单、一个质量对接人、一个交货日期。供应商越少,延误越少,扯皮越少。

应用领域

定制不锈钢压缩弹簧并非通用标准件,它们用于严苛的装配场景。

  • 医疗器械: 注射泵、外科吻合器、给药笔。采用 SUS 316L,具备耐腐蚀性和生物相容性。
  • 汽车行业: 气门弹簧、离合器分离机构、燃油喷射器内部件。采用 17-7PH,具有高疲劳寿命。
  • 工业阀门: 泄压阀和止回阀。弹簧须在数百万次循环中保持设定压力。
  • 电气开关设备: 断路器中的触头压力弹簧。镀银处理以降低接触电阻。
  • 航空航天执行机构: 伺服阀中的小直径弹簧。采用 Inconel 以适应高温环境。

如果您的弹簧失效,产品就会停机。这就是我们将公差和材质证书视为不可妥协项的原因。

客户下单前的常见问题

问:起订量是多少? 答:无起订量。我们先卷制一件供您测试,再批量扩产至 50 万件。由于采用 CNC 工艺,一件和一千件的换型成本相同。

问:如何控制公差和质量? 答:我们默认遵循 DIN 2095 二级精度。如需更严的公差,可采用一级精度,并对关键尺寸进行 100% 全检。载荷测试使用每年校准的数字测力仪完成。每批均附检测报告。

问:定制弹簧的交期是多久? 答:图纸确认后,打样件 7–12 个工作日内发货。批量订单需 15–20 个工作日。如遇急单,可分批交货——先发已完成的批次,余量随后补发。

问:能否提供材质证书? 答:可以。每批均附带 EN 10204 3.1 钢厂证书,不另收费。我们还可按需提供热处理记录和表面处理报告。
