采购商选择将图纸发给我们的三大理由

1. 批次可追溯质量。 每批产品分配唯一工单号。我们记录材料炉号、冲床参数、模具保养日期及检验员编号。如果您的装配线上出现问题,我们可在数分钟内追溯到具体班次和机台。每批出货均附带完整的可追溯性报告。

2. 每批附检测报告。 我们绝不盲目出货。每批产品均附尺寸检测报告,包含所有关键特征的实际测量值——而非仅盖“合格”章。大批量生产时,我们提供关键尺寸的X-bar和R控制图。货车到达之前,您已清楚了解所收到的每一件产品。

3. 同一工厂完成CNC加工+冲压+弹簧+散热器。 您的EMI屏蔽罩通常需要冲压框架、CNC加工散热器和弹簧夹。将全部四种零件交给同一家工厂,可降低物流成本、缩短交期,并消除配合零件之间的公差不匹配问题。我们在中国东莞的工厂内拥有全部四条产线。

这些零件的应用领域

EMI屏蔽罩并不特殊,凡有电子产品之处皆有它们的身影。

  • 通信基站: 屏蔽射频模块和功率放大器,防止串扰。
  • 汽车ECU: 在高振动环境中保护发动机控制单元免受电磁干扰。
  • 医疗设备: 隔离患者监护仪和影像设备中的敏感传感器电路。
  • 消费电子: 覆盖智能手机、笔记本电脑和智能电视中的Wi-Fi模块、蓝牙芯片及音频放大器。
  • 工业驱动器: 屏蔽变频器和伺服控制器,防止噪声干扰。
  • LED照明驱动: 抑制高频开关噪声,避免干扰附近电路。

这些零件大多尺寸较小——20 mm至80 mm见方——带有多个折弯、压凸和安装卡扣。我们的级进模可一次冲压完成所有这些特征,所有折弯线公差保持在±0.05 mm以内。

采购商下单前常见问题

问:最小起订量是多少? 答:零。无最小起订量。我们可以为您打样一件用于验证,也可以为您的生产线量产一百万件。新模具的模具费单独报价;对于现有模具系列,我们通常会复用模具以节省您的成本。

问:如何保证公差和品质? 答:我们使用三坐标测量仪进行首件检验,每批均使用销规检测孔位。冲压线上每两小时进行一次过程巡检。最终检验按AQL 2.5执行;若您的图纸有要求,关键尺寸可100%全检。

问:典型交期是多长? 答:冲压打样:图纸确认后3-5天。量产:7-15天,视数量及二次加工而定。新模具制作另需10-15天。我们通过DHL、FedEx或海运发货至全球——由您选择。

问:是否提供材质证明? 答:提供。每批出货均附带钢厂质保书,显示化学成分和力学性能。我们还可根据要求提供RoHS和REACH合规文件。

发送您的图纸

不要再同时给三家供应商发邮件然后指望其中一家做对。将您的CAD文件、材料规格和年需求量发送给我们。我们将在12小时内回复正式报价——包含价格、模具费、交期和交货条款。
