产品详情

这是一款由我们位于东莞、拥有20年经验的工厂通过精密金属冲压工艺生产的电视挂架。您将获得安装板平面度0.08mm、孔间公差±0.05mm、表面粗糙度Ra 1.6的品质——标准尺寸交期仅需15天。我们采用SPCC或SUS304钢材,硬度达400–500 HV,确保您的挂架能够稳固承载65英寸电视,无变形或蠕变。

我们的模具如何控制平面度与孔位精度

我们制造采用淬硬D2冲头和凹模镶件的级进模。模具间隙严格控制在材料厚度的5%——不多不少。这确保了剪切边缘光洁,毛刺不超过0.05mm。导正孔研磨至±0.01mm精度,因此10,000件批量生产中每件挂架的孔位布局完全一致。我们使用配备0.001mm千分表的花岗岩平台检测平面度。若零件平面度超过0.08mm,即判定为不合格,而非返修。

SPCC与SUS304:针对您的电视负载,我们推荐哪种钢材

对于32英寸至55英寸电视,我们推荐厚度2.0mm的SPCC冷轧钢板。其屈服强度为280 MPa,我们对其进行8–12微米镀锌处理以增强耐腐蚀性。对于65英寸及以上电视,或户外使用场景,我们改用厚度2.5mm的SUS304不锈钢。该材料屈服强度为520 MPa,无需额外涂层。对于旋转臂设计,我们不会冲压薄于1.5mm的材料——弯曲应力会随时间导致开裂。

V形模具中的弯曲与回弹补偿

我们的冲压设备为160吨CNC伺服压力机。我们使用修正的Siebel公式预先计算回弹角度,然后过弯2至3度。在首批50件之后,我们使用数字量角器测量弯曲角度,必要时调整模具垫片。最终弯曲角度公差为±0.5度。弯曲半径保持为材料厚度的1.5倍,以防止外表面产生微裂纹。

防锈表面处理与镀层选项

标准表面处理为光亮镀锌,厚度8–12微米,带透明三价铬钝化。该工艺通过ASTM B117标准的72小时中性盐雾测试。如需更高防护,我们提供黑色电泳涂层(15–20微米),可通过200小时盐雾测试。如需哑光外观,可选择粉末喷涂,厚度60–80微米,但交期需增加3天。冲压后原始表面粗糙度为Ra 1.6;涂层后保持在Ra 3.2以下。

每次发货前的检测:三坐标测量与拉力测试数据

每批电视挂架均经过三道检测工序。首先,我们使用三坐标测量机进行首件检验,记录15项关键尺寸。其次,对安装臂进行拉力测试——施加150 kg静态负载持续10分钟,然后检查永久变形是否小于0.2mm。第三,每500件抽取5件样品,测量孔位、平面度和涂层厚度。每次发货均附带PDF检测报告,不收取额外费用。

包装、物流与交期,满足您的生产线需求

标准交期为图纸确认后15天,从图纸审批到发货。我们将挂架逐个装入EPE泡沫袋,再放入5层瓦楞纸箱,堆码强度120 kg。每个纸箱装20件。海运时,我们使用拉伸膜缠绕托盘装载;空运时,使用加固出口纸箱。我们可提供DDP送货至美国和欧盟仓库,实现门到门交付。

我们如何处理打样与批量生产

我们不设最低起订量。将2D图纸或3D STEP文件发送给我们,我们将使用软模或线切割模具制作1至5件样品。打样交期为5天。样品确认后,我们将模具淬硬并开始批量生产。模具费用根据您的订单数量分摊,累计订购10,000件后返还50%模具费。对于重复订单,我们免费为您保管模具3年。

你们有最低起订量要求吗?

无起订量——无论是1件样品还是50,000件批量订单,我们都以相同的质量体系进行生产。

可以定制孔位布局或臂长吗?

可以,图纸确认后3天内,我们即可修改模具以适应任何孔位布局、臂长或VESA标准。

你们如何保证冲压件的质量?

我们采用三坐标测量机首件检验、安装臂150 kg拉力测试,以及每500件抽取5件进行尺寸和涂层检测。

定制电视挂架的最快交期是多少?

样品5天,样品确认后批量生产15天。

12小时内获取正式报价——发送您的图纸

将您的2D图纸或3D STEP文件连同材料、厚度和表面处理要求发送给我们。我们将在12个工作小时内回复正式单价、模具费用和交货日期。如需快速参考材料选择,请阅读我们的CNC刀具选择指南,了解模具钢牌号如何影响模具寿命。如果您正在指定挂架公差,请查阅我们的CNC加工公差指南,将您的需求与我们的能力相匹配。发送邮件至sc@bquq.com或通过WhatsApp联系+86 13713157787。这就是精密制造,中国制造,无起订量,15天交期。
