开场介绍

您的双极板图纸是起点。我们将其转化为冲压零件,并在发货前验证尺寸。无需猜测,无需您返工。

我们是BQUQ,一家位于中国东莞的精密制造工厂。我们运营金属冲压生产线已有20年。我们的工程师根据您的CAD文件检查每一个关键尺寸。在零件出厂前,我们会向您发送完整的检验报告。

精密电动汽车电池连接片

客户选择向我们发送图纸的三个理由

1. 批次可追溯的质量。 每批产品都有唯一编号。我们记录该批次的材料炉号、模具参数和检验结果。如果出现现场故障,我们可以追溯到具体生产批次。每次发货附带PDF报告。

2. 每批次附检测报告。 我们不只是冲压和发货。我们使用三坐标测量机测量流道深度、板材平面度和密封面粗糙度。您收到的是原始数据,而非摘要。这是标准服务,不额外收费。

3. 一家工厂完成CNC加工+冲压+弹簧+散热器。 您的双极板可能需要焊接弹簧触点或机加工歧管块。我们可以在同一厂区内完成所有工序。无需第三方协调,无需供应商之间的运输延误。您的图纸交给一个工程团队。

这些零件的应用领域

我们冲压的双极板应用于实际系统中,而不仅仅是实验室演示。

  • 固定式电源用PEM燃料电池。 用于电信基站和数据中心的备用发电机。极板在60–80 °C下运行,需要持续稳定的平面度以确保10,000小时以上的密封性能。
  • 便携式燃料电池堆。 无人机和小型辅助动力装置。我们冲压0.1 mm薄钛板,在保持气密流道的同时减轻重量。
  • 汽车燃料电池堆。 用于电动汽车增程器的原型和小批量生产。我们的无最小起订量政策使OEM厂商可以在承诺50,000件之前先验证50件。
  • 电解槽。 反向运行,极板几何形状相同。我们处理较厚的0.2–0.3 mm不锈钢型号,可抵抗氧气侧腐蚀。

客户下单前常问的问题

问:你们真的没有最小起订量吗? 答:是的。您可以订购1件进行装配验证,也可以订购100,000件进行批量生产。模具费单独报价,但如果您承诺首批订单,我们会将其分摊到该订单中。

问:冲压极板能达到什么公差? 答:流道深度和关键密封面为±0.05 mm。一般尺寸为±0.1 mm。我们使用三坐标测量机验证并附检测报告。如果您的设计需要更高精度,我们可改用液压成型或CNC后处理。

问:原型件的交期是多久? 答:图纸确认后10–15个工作日。包括模具制造、首件检验和运输。批量生产需要20–25天。我们可以加急在5天内交付单件,需收取加急费。

问:你们能提供材料证书吗? 答:可以。我们为您的批次中使用的每卷或每张板材提供钢厂证书。我们还可以根据要求提供化学成分报告和力学性能测试数据。所有数据均可追溯到炉号。
