Fabrication Capability at a Glance
加工能力一览
The nine steps above are only useful if you know what each one is actually capable of. The figures below are the working numbers we quote against — the same ones our engineers apply when reviewing your drawing during the free DFM stage.
只有知道每道工序的真实能力，上面这九步才有意义。下表是我们报价所依据的常规参数——也正是工程师在免费 DFM 阶段评审图纸时采用的数值。
| 01 · Drawing Design & DFM | 01 · 图纸设计与 DFM | STEP, IGES, DWG, DXF or PDF accepted; comments returned within 24 hours. Controls cost, manufacturability and which dimensions carry tolerance. | 接受 STEP、IGES、DWG、DXF 或 PDF；24 小时内反馈意见。决定成本、可制造性以及哪些尺寸需要标注公差。 |
|---|---|---|---|
| 02 · Laser Cutting | 02 · 激光切割 | Sheet from 0.5 mm to 6.0 mm, ±0.1 mm on profile. Controls hole position, edge quality and material yield from the nest. | 板材 0.5 mm 至 6.0 mm，轮廓公差 ±0.1 mm。决定孔位、断面质量与排版的材料利用率。 |
| 03 · Precision Bending | 03 · 精密折弯 | CNC press brake with per-part springback compensation; angle held to ±0.5°. Controls flange lengths and how well panels meet at corners. | 数控折弯机，按件设定回弹补偿；角度控制在 ±0.5°。决定折边长度与面板在转角处的贴合度。 |
| 04 · Forming | 04 · 成形 | Louvers, embosses, countersinks and stiffening forms. Adds rigidity without adding parts, fasteners or weight. | 冲百叶窗、压凸、沉孔与加强成形。在不增加零件、紧固件与重量的前提下提高刚度。 |
| 05 · Welding | 05 · 焊接 | TIG, MIG and spot welding, seams dressed and ground flush. Controls structural strength and whether an enclosure can hold an IP rating. | TIG、MIG 与点焊，焊缝修整打磨至平整。决定结构强度以及外壳能否达到 IP 防护等级。 |
| 06 · Grinding & Deburring | 06 · 打磨去毛刺 | Edge break on every cut edge before finishing. Controls coating adhesion at edges — the first place corrosion starts — and handling safety. | 表面处理前对所有切割边做倒角去刺。决定边缘处的涂层附着力（腐蚀最先发生的位置）与操作安全。 |
| 07 · Riveting | 07 · 铆接 | PEM and blind rivet hardware, press-in studs and standoffs. Controls threaded mounting points and their resistance to torque in service. | PEM 与抽芯铆钉、压铆螺柱与支撑柱。决定螺纹安装点及其在使用中抗扭矩的能力。 |
| 08 · Powder Coating | 08 · 粉末喷涂 | Electrostatic application at 60–90 μm dry film thickness over a multi-stage pretreatment. Controls corrosion life and colour consistency to your RAL code. | 多级前处理后静电喷涂，干膜厚度 60–90 μm。决定防腐寿命与按 RAL 色号的颜色一致性。 |
| 09 · Assembly & QC | 09 · 装配与质检 | Full build with gaskets, hinges, latches and sub-plates, followed by a dimensional report. Controls door fit, sealing and whether the unit assembles on your line the first time. | 含胶条、铰链、锁扣与安装板的整机装配，随后出具尺寸报告。决定门板配合、密封性以及能否在你的产线上一次装成。 |
What Really Determines Quality at Each Stage
决定每道工序质量的关键
Two fabricators can run the same nine steps and ship very different parts. The gap shows up in the details below — the ones that surface during a drawing review rather than on a capability list.
两家制造商走完同样的九道工序，交出的零件可能差别很大。差距体现在下面这些细节上——它们出现在图纸评审中，而不是能力清单上。
Kerf compensation and hole size
切缝补偿与孔径
The laser kerf is compensated in the nest, so the dimension you should tolerance is hole position, not the kerf. As a working rule, pierced holes should not be much smaller than the material thickness — below that, pierce quality falls off and cycle time climbs without any gain in accuracy.
激光切缝在排版时已做补偿，因此应标注公差的是孔位而不是切缝。经验法则是冲孔孔径不宜小于板厚——再小的话，穿孔质量会下降、节拍会变长，而精度并无提升。
Springback and minimum bend radius
回弹与最小折弯半径
Every material and gauge springs back differently, so compensation is set for the specific part and verified on the first piece rather than assumed. For cold rolled steel the minimum inside radius is typically close to material thickness; push tighter and you risk cracking along the outside of the bend.
不同材料与厚度的回弹量各不相同，因此补偿按具体零件设定并在首件验证，而不是凭经验假设。冷轧钢的最小内圆角通常接近板厚；再小就有沿折弯外侧开裂的风险。
Hole-to-bend clearance
孔到折弯边的距离
Keep holes at least two times material thickness plus the bend radius away from the bend line. Closer than that and the hole pulls into an oval — one of the most common reasons assembly holes refuse to line up, even when every individual dimension measures in tolerance.
孔到折弯线的距离应至少为两倍板厚加折弯半径。距离过近，孔会被拉成椭圆——这是即使每个尺寸都测量合格、装配孔仍然对不上的最常见原因之一。
Seams, coating thickness and threads
焊缝、膜厚与螺纹
A weld that looks sound can still leak, so IP-rated enclosures get seams dressed and ground before coating and then verified with a water test. Film thickness is a balance: powder coating at 60–90 μm stays thin enough to keep threads usable and thick enough for outdoor life.
看起来完好的焊缝仍可能渗漏，因此有 IP 等级要求的外壳会在喷涂前修整打磨焊缝，再用水测试验证。膜厚需要平衡：60–90 μm 的粉末喷涂既薄到不影响螺纹使用，又厚到足以保证户外寿命。
Inspection & Quality Control
检验与质量控制
Inspection happens at three points rather than one, because a defect caught at the machine costs a fraction of one caught at the customer. Our sheet metal quality control guide covers the measurement methods in detail.
检验分三个节点而非一个，因为在机床上发现的缺陷，代价远低于在客户处发现。钣金质量控制检验指南详细介绍了各类测量方法。
First Article Inspection
首件检验
The first part off the line is measured against the drawing before the rest of the batch is cut. Critical dimensions are recorded, and the report ships with the sample so you can check our numbers against your own.
批量切割前，首件先按图纸测量。关键尺寸会被记录，报告随样品一同寄出，方便你用自己的测量结果核对。
In-Process Checks
过程检验
Dimensions are checked at the machine rather than at the end of the line, so any drift is caught inside the batch where it happened — not after a thousand parts have already been made to the same wrong number.
尺寸在机床上检测，而不是在产线末端，因此任何偏差都能在发生批次内被发现，而不是等一千件都按同样错误的尺寸做完之后。
Final Inspection
成品检验
Finished enclosures are checked for fit, finish, coating thickness and — where specified — ingress protection. IP54–IP66 is verified on the assembled unit, not on a separate test coupon, because gasket compression depends on the real door.
成品外壳需检验配合、外观、膜厚以及（若有要求）防水防尘性能。IP54–IP66 在整机装配状态下验证，而非单独的试片——因为胶条压缩量取决于真实的门板。
Frequently Asked Questions
常见问题
How long does the whole process take?整个流程需要多久？
DFM comments come back within 24 hours. Standard parts ship in 7–15 days and custom builds take 20–30 days, with the finish, complexity and quantity driving most of the variation.
DFM 意见 24 小时内反馈。常规件 7–15 天发货，定制件 20–30 天；表面处理、复杂度与数量是造成周期差异的主要因素。
What tolerances can you hold?能做到什么公差？
±0.1 mm on laser-cut profiles and CNC-bent features, with bend angles held to ±0.5°. Tighter is sometimes possible, but we flag what it will cost before quoting. Our sheet metal tolerance guide explains where tight tolerances pay off and where they do not.
激光切割轮廓与数控折弯特征 ±0.1 mm，折弯角度 ±0.5°。更严的公差有时可行，但我们会先说明成本再报价。钣金公差指南解释了哪些地方收紧公差值得、哪些不值得。
Can you handle both prototypes and mass production?打样和量产都能做吗？
Yes, and that is the point of a tool-free process: the prototype and the production part are made the same way, so what you approve is what you receive at volume. There is no tooling to re-cut and no second supplier to qualify.
可以，这正是免模具工艺的意义：打样件与量产件用同样方式生产，你确认的就是批量收到的。无需重开模具，也无需重新认证第二家供应商。
What file formats do you accept?接受哪些文件格式？
STEP or IGES for 3D, DWG or DXF for 2D, and PDF is fine for a start. If you have none of these, send a physical sample or photographs with rough dimensions — we will model it for you.
3D 用 STEP 或 IGES，2D 用 DWG 或 DXF，先提供 PDF 也可以。如果都没有，可寄送实物样品或附粗略尺寸的照片——我们可代为建模。
