这是我们冲压钣金外壳与盖板系列——一系列精密成型的钢制和铝制盖板,设计用于保护恶劣工业环境中的电子设备、传感器和机械组件。每个零件均保证公差±0.05毫米,表面光洁度可达Ra 0.8,标准交期为图纸确认后10个工作日。您将获得无需返工即可与配合组件完美匹配的外壳,在中国严格BQUQ工艺控制下制造。

我们的级进模如何在5万次冲压中保持±0.05毫米精度

我们采用带硬化工具钢镶件(62 HRC)的级进模和四柱导架结构,确保冲头与凹模间隙均匀。这种设置消除了廉价模具常见的渐进漂移问题,尤其是在长度超过150毫米的零件上。法兰盖板的跳动量保持在0.03毫米以下。对于大批量生产,我们对磨损表面进行碳化物涂层处理,将模具寿命延长至120万次冲压,且尺寸变化可检测前无需维护。

我们用于外壳盖板的材料与热处理

我们常备SPCC冷轧钢(0.5–3.0毫米)、SECC电镀锌钢和5052-H32铝合金作为标准选项。对于不锈钢需求,我们提供SUS304和SUS316L,厚度从0.4毫米到2.5毫米。当您的盖板需要额外刚度或耐磨性时,我们提供选择性边缘感应淬火,硬度可达48 HRC。所有原材料卷材均附带钢厂证书,并在投入生产前进行屈服强度测试。

去毛刺与表面处理:Ra 0.8无需二次加工成本

每个冲压盖板都经过两阶段去毛刺生产线——首先使用陶瓷介质的振动研磨机,然后进行干式砂带打磨。这消除了切割边缘和法兰上的所有微毛刺,使零件在可见表面上达到Ra 0.8的安全处理等级。对于外观装饰性表面,我们提供拉丝、喷砂或粉末喷涂表面(厚度60–120微米),可选任何RAL颜色。您无需进行二次去毛刺处理。

法兰盖板和带唇外壳的成型与折弯精度

我们的数控折弯机配备CNC后挡料和角度感应激光器,可将折弯角度控制在±0.5度以内。法兰高度控制在±0.1毫米以内,我们对所有关键折弯半径采用压印步骤,以消除回弹变化。对于深拉深盖板(深度>40毫米),我们使用AutoForm软件在内部进行拉深模拟,减少模具调试时间并确保壁厚分布均匀。

每次发货前检验:三坐标测量机和高度规验证

冲压钣金外壳与盖板系列的每批零件均在分辨率为0.5微米的三坐标测量机(CMM)上检测。我们根据您的图纸检查所有关键尺寸、孔位和平面度。此外,我们对所有可见表面进行100%目视检查,检查划痕、凹痕或变色。每次发货均附带完整尺寸报告,因此如果您的系统允许,您可以跳过进料检验。

海运或空运的包装与防锈保护

所有盖板均用VCI(气相防锈)纸单独隔开,然后装入带泡沫内衬的出口级瓦楞纸箱中。对于铝制零件,我们使用中性pH纸以防止氧化。如果通过海运发货,我们为每个单元添加干燥剂包和热封PE袋。这可使您的零件在仓库条件下长达12个月内不生锈。

通过内部模具制造和二次加工降低成本

我们的模具车间内部制造所有级进模和复合模,与外包模具相比,模具成本降低30–40%。我们还内部完成攻丝、锪孔和铆接,因此您无需为多个供应商付费。这种整合使我们能够提供无最小起订量——即使是单个原型盖板也在与10,000件订单相同的生产线上生产,并执行相同的质量检查。

你们有最小起订量要求吗?

无最小起订量——我们接受单件原型订单,并可扩展至大批量生产,无任何价格惩罚。

你们可以根据我现有的CAD模型定制盖板吗?

可以,请将您的STEP或IGES文件发送给我们,我们的工程师将在24小时内验证可成型性、添加折弯释放槽,并提出材料厚度变更建议。

你们如何确保小批量订单的质量?

我们对1件批次执行与10,000件批次相同的三坐标测量机检测和目视检查,并随货附带尺寸报告。

典型生产交期是多久?

对于无需定制模具的冲压盖板,我们在10个工作日内发货;如果需要新模具,则增加15天用于模具制造和样品确认。

有关将切削刀具与合适材料匹配的详细信息,请参阅我们的CNC切削刀具选择指南。如果您需要了解我们能达到的尺寸精度范围,请将我们的规格与博客上的CNC加工公差指南进行对比。
