精密CNC加工无人机相机支架

我们能够保持严格公差,因为活塞工作在恶劣环境中。材料与涂层由您的设计决定。我们负责加工与验证。

买家选择向我们发送图纸的三个理由

1. 批次可追溯的质量 每批次都有唯一工单编号。我们记录材料炉号、操作人员、刀具补偿和检测结果。如果零件在使用中出现问题,我们可以追溯到具体班次和刀具。无需猜测。

2. 每批次附检验报告 每次发货您都会收到完整的尺寸检测报告。我们测量每一个关键特征——销孔直径、环槽宽度、顶部厚度、裙部轮廓。我们使用三坐标测量机(CMM)和气动量仪,而非卡尺。报告由质检主管签字并随零件一同发送。

3. 同一工厂完成CNC加工+冲压+弹簧+散热器 我们在同一厂房内运营四条生产线。如果您的组件需要冲压支架、弹簧座圈或附近电子元件的散热器,我们都能制造。您只需对接一个供应商、一个发货点、一张发票。更少麻烦,更快周转。

这些零件的应用领域

CNC加工活塞不仅用于赛车。我们为以下领域供货:

  • 高性能汽车发动机 — 涡轮增压和自然吸气改装用锻造铝活塞
  • 赛车运动和船舶 — 用于耐力赛和舷外机的轻量化活塞
  • 压缩机和泵 — 用于液压和气动系统的精密活塞
  • 液压缸 — 表面镀硬铬或渗氮处理的钢制活塞
  • 研发领域 — 用于发动机测试的一次性原型活塞
  • 小型发动机 — 发电机、园林设备和二冲程发动机用活塞

在每种应用中,活塞都必须可靠密封、滑动并传递力而不失效。我们的加工确保了实现这一目标的几何精度。

买家下单前常问的问题

问:你们真的没有最小起订量吗? 答:是的。我们加工一个原型件或整个量产批次均可。没有最低订购要求。原型件单价略高,但设置费用相同。我们保持简单透明。

问:你们如何保证公差和质量? 答:我们对每件产品的所有关键尺寸进行100%检测。对于批量生产,我们采用SPC抽样加上首件全尺寸CMM检测。检验报告随货附送。如果零件超出规格,我们免费更换。

问:定制CNC加工的交期是多久? 答:图纸确认后,原型件10–15个工作日内发货。量产批次需要20–25个工作日。可提供加急服务(需额外费用)——简单零件可压缩至7天。

问:你们能提供材质证书吗? 答:可以。每批次我们都提供原材料的钢厂证书。对于航空航天或汽车行业需求,我们还提供炉号及化学成分的可追溯性。
