Product Overview
产品概述
A mini PC chassis looks like the simplest enclosure we make, and it is the one that punishes shortcuts hardest. There is no spare volume inside. Every millimetre given to a vent pattern is taken from cable routing; every cutout moved is a port that no longer lines up with the board. When a design like this fails, it fails at assembly, not on the drawing.
迷你电脑机箱看起来是我们做的最简单的外壳，却也最容易暴露设计上的偷懒。它的内部没有多余空间：通风图案多占一毫米，走线就少一毫米；任何一个开孔位置偏移，都会导致接口与主板对不上。这类设计一旦出问题，往往是在装配环节暴露，而不是在图纸上。
We build these around the board, not around a catalogue size. You tell us the motherboard — Mini-ITX, thin-client or a proprietary industrial board — and we work outward from its I/O shield, its mounting hole pattern and its cooler height. The result is a chassis that closes the first time and cools what is actually inside it.
我们围绕主板来设计机箱，而不是套用某个目录尺寸。您只需告知主板型号——Mini-ITX、瘦客户机主板或定制工业板——我们便从其 I/O 挡板、安装孔位与散热器高度向外展开设计。最终得到的是一次就能合盖、且能真正为内部器件散热的机箱。
The standard build is SPCC cold-rolled steel, laser cut and CNC bent, seam welded at the corners and finished in a matte black powder coat. Perforated top and side panels provide the air path; the shell itself, being continuous metal with designated grounding points, does the EMI work. Where the install is behind a display we add VESA or wall-mount points and move the vents so they are not facing the wall.
标准配置为 SPCC 冷轧钢，激光切割后数控折弯，转角缝焊，表面做哑光黑色粉末喷涂。顶面和侧面的冲孔网板提供气流通道；壳体本身是带指定接地点的连续金属体，由它来完成电磁屏蔽。若安装在显示屏背后，我们会增加 VESA 或壁挂安装点，并调整通风位置避免正对墙面。
Nothing here is a stock item. Every chassis on this page started as a drawing, a sample or, quite often, a photograph of a competitor part with a ruler beside it. We take the geometry you already have and make the metal around it.
这里没有现货件。本页的每个机箱最初都来自一张图纸、一个样件，或者更常见地，一张旁边放着尺子的竞品照片。我们围绕您已有的接口几何来制造金属部分。

Engineering Highlights
工艺要点
I/O Cutouts That Meet the Board
开孔与主板对得上
Panel cutouts are positioned from your I/O shield drawing rather than a generic template, and clearances are verified on the first article with the actual connectors plugged in.
面板开孔依据您的 I/O 挡板图纸定位，而非套用通用模板；首件阶段会实际插拔连接器来验证间隙。
Vent Area Sized, Not Copied
开孔率按热负荷计算而非照抄
We balance open area against panel stiffness, fan static pressure and EMI leakage. More holes is not more cooling once the fan is already moving air, and it costs you rigidity and shielding.
我们在开孔率、面板刚度、风机静压与电磁泄漏之间取平衡。当风机已有足够风量时，孔开得更多并不会提升散热，反而损失刚度与屏蔽效果。
Grounding Designed In, Not Added
接地是设计出来的，不是加出来的
Shielding continuity depends on seams and the largest aperture, not on material thickness. We keep the shell electrically continuous and give you defined grounding points before the first part is cut.
屏蔽连续性取决于接缝与最大开孔尺寸，而非板厚。我们在下料前就让壳体保持电气连续，并为您明确接地点位置。
Mounting That Carries Real Weight
安装点承载真实重量
Wall and VESA mount points are reinforced at the frame rather than relying on the sheet alone, because a chassis hung behind a display loads its mounting features in a way a desktop chassis never does.
壁挂与 VESA 安装点在框架处做补强，而不是仅靠板材本身——挂在显示屏背后的机箱，其安装特征受力方式与桌面机箱完全不同。

Frequently Asked Questions
常见问题
What is the minimum order quantity?起订量是多少？
MOQ is 1 piece. A mini PC chassis is a part you should hold in your hands and populate with your real board before committing to a batch, so we prototype first and quote the batch from the validated design.1 件起订。迷你机箱这样的零件，您应当先拿在手里、装上真实的主板验证过，再决定批量——所以我们先打样，并以验证后的设计来报量产价。
Can you cut the I/O panel to our motherboard layout?能按我们的主板接口开 I/O 面板吗？
Yes, and this is the part that matters most. Send the board model or the I/O shield drawing and we position HDMI, DP, USB, Ethernet and power entry cutouts against it, then confirm clearances on the first article before batch.可以，而且这是最关键的一环。请提供主板型号或 I/O 挡板图纸，我们会据此定位 HDMI、DP、USB、网口与电源入口，并在批量前用首件确认间隙。
How do you handle cooling in a chassis this small?这么小的机箱怎么解决散热？
We size the vent open area against your heat load and the fan you plan to use, rather than copying a generic hole pattern. Too much open area weakens the panel and leaks EMI; too little stalls the fan. We balance the three at DFM review.我们按您的热负荷与拟用风机来确定开孔率，而不是照抄通用孔型。开孔过多会削弱面板并泄漏电磁；开过少则风机憋压。我们在 DFM 评审时平衡这三者。
Do you provide EMI shielding and grounding?是否提供电磁屏蔽与接地？
The enclosure is a continuous folded and welded metal shell with designated grounding points. Aperture size and seam continuity are reviewed at design stage, because shielding is determined by the largest opening, not by the material thickness.机箱为连续折弯焊接的金属壳体，并设有指定接地点。开孔尺寸与接缝连续性在设计阶段就会评审，因为屏蔽效果取决于最大开孔尺寸，而非板厚。
What material and thickness should I use?应该用什么材料和板厚？
SPCC cold-rolled steel at 1.2-2.0 mm is the usual choice for a rigid, low-cost indoor chassis. Where weight matters we quote aluminium 5052, and for outdoor or wash-down sites we quote SUS304. Tell us the environment and we will recommend one.室内刚性优先、成本敏感时通常选 1.2–2.0 mm 的 SPCC 冷轧钢；关注重量时我们报 5052 铝板；户外或需要冲洗的场景报 SUS304。请说明服役环境，我们会给出推荐。
Can you work from a sample chassis or photos only?只有样机或照片，没有图纸，可以做吗？
Yes. Send the sample, or clear photos with a scale reference, plus the board you intend to fit. We reverse engineer it into a model, a flat pattern and a dimensioned drawing for your approval.可以。请寄来样件，或提供带比例参照的清晰照片，并说明拟装入的主板，我们会逆向出模型、展开图与标注图纸供您确认。
