本系列产品概述及关键硬性数据

本系列是完整的冲压风扇防护网罩和金属丝网盖产品线,由我们东莞工厂使用运行20年的CNC冲压生产线生产。无需二次机加工即可实现0.08 mm平面度、±0.05 mm孔位公差和Ra 1.6 µm表面光洁度。标准尺寸交货期为15天,碳钢版本表面硬度可达45 HRC。

我们的金属丝网盖为何在高风量下抗变形

风扇防护网罩失效通常是因为网面在压力或振动下发生弓曲变形。我们通过模具中的二次冲压压印工艺解决这一问题,将丝网交叉点压缩至一致的0.3 mm厚度。这意味着您的防护网罩在3,000 RPM风扇转速和高达80°C环境温度下仍能保持形状。整个面板的网孔尺寸公差控制在±0.1 mm以内,确保气流可预测性,同时手指安全合规性(IP20)绝无问题。

我们使用的材料及耐腐蚀抗冲击热处理工艺

我们常备三种基材:Q195碳钢适用于成本敏感型应用,SUS304不锈钢适用于冲洗环境,镀锌SPCC适用于户外设备。碳钢零件经过860°C受控奥氏体化处理,随后油淬,再在180°C回火——这可在不使丝材变脆的情况下达到45 HRC硬度。不锈钢版本跳过热处理,但经过电解抛光处理以保持Ra 1.6 µm并通过72小时盐雾测试。如需特定丝径,我们支持0.8 mm至4.0 mm丝径,中心距从5 mm至25 mm可选。

模具寿命和工装精度确保您的单件成本稳定

我们的级进模采用D2钢制造,硬度为60 HRC,以每分钟120次冲程运行。这种模具结构可承受500,000次冲压后才需重新研磨刃口,这意味着您的单件价格不会在首批10,000件后悄然上涨。对于定制防护网罩,我们收取一次性模具费$800至$2,500,但在您首批50,000件完成后退还50%费用。本系列标准尺寸无需任何模具投资——您下单,我们直接冲压。

每批出货前检测:三坐标测量机和光学投影仪

每批次均经过三级检测。首先,制程操作员每50件使用通止规检测孔位。其次,三坐标测量机(CMM)每批抽样5件,验证整体平面度和直径跳动至0.05 mm。第三,光学投影仪以20倍放大倍率测量网孔角度。我们向您发送包含实际测量值的PDF报告,而非仅通过/不通过的勾选框。如有任何零件超出公差范围,整批将被隔离并重新生产——绝无例外。

海运包装及防锈保护

成品防护网罩采用交错隔纸堆叠,防止运输过程中表面划伤。对于碳钢零件,我们在密封入出口级纸箱前使用VCI(气相防锈)薄膜包裹。这可在潮湿集装箱中保护零件长达六个月——适用于发往美国和欧盟的标准运输。不锈钢零件采用相同方式包装但不使用VCI,因此您无需担心网面残留化学物质。

如何在控制预算的前提下处理定制形状

大多数风扇防护网罩为圆形或方形,但我们同样冲压椭圆形、三角形和多孔安装模式。发送2D DXF或3D STEP文件,我们的工程师将在一个工作日内回复模具可行性意见。对于带中心孔的简单圆形防护网罩,我们使用可加装简易镶件进行修改的标准模具系列——仅需$150即可更改孔型。对于小半径复杂形状,我们在切割钢材前使用AutoForm进行回弹模拟。您将获得固定而非预估的模具报价。

全球买家订购流程及付款条款

我们接受通过电子邮件或WhatsApp询价,并在达成协议后12小时内出具形式发票。付款方式为30% T/T定金,70%发货前付清。对于重复订单,在三次已付款发货后可转为月结30天条款。我们通过DHL、FedEx或海运发货——由您选择。对于小批量订单,我们收取每单$25的固定包装费,但标准尺寸无任何模具摊销隐藏费用。

是否有最小起订量要求?

无起订量——我们接受单件打样,且随着数量增加,单件价格呈线性下降。

能否根据我的图纸匹配特定丝网图案?

可以,我们能够复制最大600 x 600 mm的任何图案,但建议您先查阅我们的CNC切割刀具选用指南,以确保您的模具材料与我们使用的丝材硬度相匹配。

单件原型如何验证质量?

即使是单件订单也经过相同的三坐标测量机检测,我们会将测量报告连同物流跟踪号一并发送至您的邮箱。

定制冲压防护网罩的最快交货期是多久?

如果您的设计使用标准丝径和现有模具镶件,我们可在7天内发货;如需新开模具,预计20天,我们始终在您付款前确认确切日期。

工程师为何从冲孔板转向我们的冲压丝网

冲孔板切割边缘有毛刺且开孔率有限。我们的冲压金属丝网采用剪切动作,两面均留下干净边缘,因此无毛刺刮伤线缆或手指。使用1.5 mm丝径、10 mm间距时,开孔率可达65%,而同厚度冲孔板通常仅为45%。这意味着您的风扇在相同电机下可推动更多空气,节省能源并降低噪音。如果您正在比较供应商,请索取我们的CNC加工公差指南,了解我们如何在冲压件——而非机加工件——上保持±0.05 mm公差。

最终成本对比及您的实际支出

对于200 x 200 mm碳钢防护网罩,1.5 mm丝径、10 mm间距,1,000件时单价为$0.85。10,000件时降至$0.62。SUS304不锈钢每件贵35%,但可省去后续喷漆或电镀成本。标准圆形防护网罩模具费为$0——我们已有现成模具。定制矩形防护网罩模具费为$1,200,50,000件后退还50%。1,000件海运至洛杉矶运费为$180,如需5天内到货,DHL运费为$95。无其他费用——无设置费、无样品费、第一年无模具维护费。

12小时内获取确定报价

将您的图纸以DXF、DWG、STEP格式甚至带尺寸的手绘草图发送给我们。我们的工程师将回复确定价格、模具费用(如有)和确切交货日期——而非区间范围。我们位于东莞时区(GMT+8),在12个工作小时内回复每一条询盘。发送邮件至sc@bquq.com或通过WhatsApp联系+86 13713157787,告知您的目标数量和材料偏好。如果您对公差不确定,请附上应用的工作温度和风扇转速——我们将推荐合适的丝径和硬度。
