这是一套完整的冲压金属组件,用于AI服务器和高密度计算机架中的液冷歧管。我们生产这些部件的尺寸公差为±0.02 mm,平面度跳动最大0.05 mm,表面光洁度Ra 0.8 µm。从图纸确认起,典型交期为12个工作日,该系列产品无起订量要求。

为何歧管冲压件优于机加工块体用于AI冷却

液冷歧管需要许多相同的通道、端口和安装凸台。冲压可一次冲程成型这些特征,而非一次切削走刀。对于典型的AI机架歧管,我们的冲压工艺在10,000个零件上保持0.01 mm的重复精度。这比CNC铣削更快、更经济,且淬硬模具确保每个零件与上一个完全一致。您获得的歧管在每个接头处均能一致密封,这在冷却液压力达到4 bar时至关重要。

我们用于冷却液接触的材料和热处理

该系列我们常备三种材料。第一种,SUS304L用于承载去离子水的歧管——耐点蚀且不会析出金属离子。第二种,C5210磷青铜用于歧管内部的弹簧加载阀板;其硬度为180 HV,摩擦系数低。第三种,6061-T6铝用于轻量化结构支架,硬化至95 HRB。对于高压区域,我们在碳钢(DC01)上增加0.2 mm镀镍层,以通过72小时盐雾试验。所有材料均附带钢厂证书,我们每200件进行一次批量硬度测试。

密封面的关键平面度和跳动控制

泄漏发生在歧管面与垫片或O型圈接触处。我们通过使用带精密导柱的复合模具来控制这一点,保持冲头和凹模间隙为0.03 mm。冲压后,我们对所有密封面进行100%光学平面度检查。结果:在200 mm长度上最大跳动为0.05 mm。这个数字很重要,因为平面度好、跳动低的表面允许您使用更薄、更便宜的垫片而不影响密封。我们还将所有边缘去毛刺至0.1 mm圆角半径,确保没有锋利毛刺切入您的冷却管路。

我们如何防止内部流道产生毛刺

歧管通道内部的毛刺会产生湍流和压降,还会截留颗粒,堵塞冷板中的微通道。为防止这种情况,我们采用两步冲压工艺:先粗冲毛坯,再用带V型环压边圈的精冲工序。这产生干净的剪切区而无断裂。我们使用激光轮廓仪测量毛刺高度。该系列的最大毛刺高度为0.02 mm。如果您的图纸指定更严格的限制,我们改用整修模具,可将毛刺高度降至0.005 mm。

每次发货前检验:CMM和压力测试

没有冲压件能在未附完整数据表的情况下离开我们的东莞工厂。我们使用蔡司CMM验证每个歧管的5个关键点:端口间距、孔径、平面度、跳动和厚度。对于500件批次,我们检验20件进行100%测量,其余使用通止规检查。我们还随机进行1%的6 bar气压测试,确认无微裂纹。您将收到附批次号的PDF检验报告。如发现偏差,我们立即停机并重新认证模具后再继续生产。

保持公差稳定的模具和保养

冲压歧管的质量取决于模具。我们按固定计划维护所有模具:每5,000次冲程后,检查冲头刃口并重新润滑导柱。每20,000次冲程后,更换磨损镶件。这就是为什么我们能保证您的第10个订单与第1个订单具有相同的±0.02 mm公差。如果您正在设计新歧管,请阅读我们的CNC切削刀具选择指南,了解刀具磨损如何影响零件几何形状。如需深入了解我们如何定义和测量公差,请参阅我们的CNC加工公差指南

精密歧管表面的运输和包装

表面划伤是最常见的运输损坏。我们将每个歧管单独装入防静电袋,然后放入带泡沫衬垫的定制瓦楞托盘,将零件固定到位。200件以上订单,我们使用带防潮层的胶合板木箱。每个箱子贴有红色“易碎 – 密封面”标签。我们通过DHL、FedEx或从深圳港海运发货。空运时,生产完成后3天内您的零件即可抵达香港机场。我们的出口文件包括完整装箱单和中国制造原产地证书。

能否定制端口尺寸和螺纹类型?

可以,我们可以调整端口直径、螺纹类型(NPT、BSP、G螺纹)和孔位,但需要您的2D或3D图纸——我们将在24小时内报价定制模具。

大批量生产时如何控制质量?

我们每批次抽取20件进行100%关键尺寸检验,外加1%压力测试,并在发货前通过电子邮件发送CMM报告。
