Contact & Get a quote Tell us what you are building You get back a quote, a DFM note on anything that will bite you, and — where we can — the design changes that cut cost. Direct lineFelipe Iglesias · Co-founder[email protected] · +86 13126536955General inquiries: [email protected] · +86 0769-83798939Factory: No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470Languages: English · Português · Français · Español · 中文 · 日本語. Time zone: China Standard Time (UTC+8). Why you are here You are here because you have a BOM and a CAD model, and you are deciding who builds it. You are not looking for a brochure; you are looking for a factory that can take a design from an early prototype to a shipping product — without handing the board to one vendor and the enclosure to another. That is the reason we run EMS and CNC under one roof in Dongguan. When the electronics assembly and the machined enclosure are made in the same building, the person who designs the board and the person who cuts the housing talk to each other before you have to referee between them. The connector that does not clear the lid gets caught at DFM, not at final assembly on your loading dock. We are a Dongguan manufacturer — 6,800 m² in Hengli, more than 100 staff, running since 2006 (Zhuohang) — and we take orders with no minimum. A single prototype is a valid order, and the same line that builds one will build the next ten thousand when you are ready. What happens after you write Every inquiry lands with a person, not a queue. Felipe reads the BOM and drawing, routes it to the engineer who owns that process, and you get a reply that moves the project forward. We are an EMS and CNC manufacturer in Dongguan — electronics assembly first, machining second, all under one roof in Hengli — so one email reaches both sides of the build. Here is the path from your message to a first article, in the order it actually happens. We review for DFM first. Your files go to the manufacturing engineer who will run the job, not to a sales layer. They look for the features that drive cost or fail in service: a wall too thin to anodize without warping, a blind hole that traps chips, a BGA that needs a specific stencil aperture, a connector set too close to the board edge to reflow reliably. Every issue is flagged with the fix, and where we can, the change that cuts cost. You get this before you get a number, because a DFM note that arrives after you have committed is not worth much. We quote the bracket, not a teaser. The quote fixes unit price, tooling if any, lead time, and the tolerance we will hold. It states the quantity bracket it is valid for — a prototype run is not priced like a 10,000-unit ramp, and we do not pretend otherwise. If a component has a twelve-week supply risk, it is named in the quote by part number, not discovered later. We lock it with a first article. Before volume, a first-article inspection and, where you require it, a PPAP package pin the process to the specification. You approve the part, not a promise. Only then does production move. That flow is the same whether you are at EVT with a rough prototype, DVT with a near-final design, or PVT ready to release. The gate you are at changes what we flag, not whether we flag it. The loop is built for the buyer who has been burned: quoted a price, then billed for tooling they were never told about; promised a lead time, then told a part was on backorder. We close those gaps by putting the DFM review first, the bracket in writing, and the first article before volume. You approve the part, not a promise. What to send Send the minimum that lets an engineer quote accurately. Over-sending slows nothing; under-sending forces a round of clarifying emails. The list is short, and it differs by what you are building. Mechanical parts — CNC Solid model: STEP, IGES or Parasolid. STEP is the most portable; send one file, not a folder of loose surfaces. 2D profile: DXF or DWG for flat patterns, sheet profiles and anything defined in two dimensions. Toleranced drawing. This is not optional. The model says the shape; the drawing says what matters. Call out datums, the two or three features with tight tolerance, and any surface finish, plating or heat treatment. If the part mates with another, say so — it changes how we fixture it. Electronics — EMS / PCBA Gerbers (RS-274X) plus the board outline and layer stackup. BOM as CSV or spreadsheet, with manufacturer part numbers and approved alternates. A BOM without part numbers gets a quote with a question mark next to it. Pick-and-place file (centroid) with rotation, so placement is checked against the Gerbers rather than guessed. Panelization and inspection standard. Tell us if you want a panel, and whether you expect IPC-A-610 class 2 or class 3 — it changes how we quote and how we inspect. Test requirements. If you expect ICT, flying probe or functional test, say so — it changes tooling and the quote. If the board carries firmware, tell us whether you flash it or we do. If the enclosure holds the board, send both sets. The fastest quotes are the ones where we can see how the electronics and the machined part actually meet. One more thing that speeds everything: name the product. "Medical pump controller" tells us more in three words than a paragraph of description, and it sets the certification and traceability expectations before we even ask. A note on the toleranced drawing: it is the cheapest cost-reduction tool you own. Every dimension you leave untoleranced gets a default, and a default is usually tighter than you need and more expensive than you want. Ten minutes marking the three features that matter will save more on the quote than any negotiation will. How to get an accurate quote Five pieces of information separate a quote you can commit to from a number you will have to redo. None of them takes long to write, and each one removes a guess. Quantity now, plus forecast. Tell us the run you need today and the volume you expect over the next twelve months. Tooling and setup amortize differently at 50 units than at 50,000, and a forecast lets us price the bracket honestly instead of burying margin in a one-off. Tolerances that matter. Mark only what is critical. Every tight tolerance adds cost; a drawing that says everything is ±0.01 mm where nothing needs it is a tax you chose. Tell us which features actually carry the function. Finish. Anodize, plating, powder coat, conformal coating, silk screen. Name the spec, not just the color — a decorative anodize and a hard-coat anodize are different processes at different prices. End-use. Medical, aerospace, automotive or consumer. It drives material traceability, testing, and the certification the job must carry. Target date. Your date sets the bracket. A part needed in three days is priced and scheduled differently from one needed in thirty. Missing one of the five? Send the four you have. We will quote the parts we can see and tell you exactly which missing item changes the number, so you decide whether to chase it down. A quote held hostage to a perfect data package helps nobody. What the quote contains A quote from us is a short document, and every line is there so you can compare like with like. Ask a competitor for the same items and you can line the two up side by side. Line itemWhat it tells you Unit priceCost per part or per board at the quantity bracket we quoted. Tooling and NREFixturing, stencil or programming cost, stated once and separated from unit price. Lead timeDays from order to ship, in the 3 / 7 / 30-day bracket your job falls into. Tolerance we holdThe dimensional band we commit to, so you know what you are buying. DFM noteThe issues we found and the changes that cut cost or make it more robust. Supply riskLong-lead components flagged by part number, not after the fact. There is no MOQ in any of it. A single prototype is a valid order, and the quote covers the bracket you are actually buying. How to compare quotes fairly Unit price is the easiest number to compare and the easiest to misread. Two shops can quote the same part at $4.10 and $4.80 and still be far apart once you line up the rest: is tooling included or added later, is the tolerance the one you actually need, does the lead time hold, and does the quote name its long-lead parts. Before you choose, ask every bidder the same four questions and hold the answers side by side. Is tooling and NRE in the unit price, or listed separately? What tolerance do you commit to hold, in writing? What is the lead time, and what voids it? Which components in my BOM are long-lead, and what is the alternative? A bidder who will not answer those four in writing is telling you something useful about how the job will actually go. Response time We answer within about one business day — faster for a simple machined part, a little longer for a full BOM with supply-chain checks. The reply is a real quote, or a short list of the three questions standing between us and a real quote. It is never a generic acknowledgment. A business day here runs roughly 8:30 to 18:00 China Standard Time; requests that arrive in our evening are answered the next morning, which is still your afternoon or evening in the Americas. If you are in another time zone, expect the reply to land overnight. China Standard Time (UTC+8) runs roughly twelve hours ahead of US Eastern, so a request sent on a Tuesday afternoon in Boston is answered by the time you sit down on Wednesday. If you prefer to talk rather than type, the direct line above is the fastest path: we work in English, Portuguese, French, Spanish, Mandarin and Japanese. Who you are talking to You deal with one person from first email to shipped part. Felipe Iglesias is a co-founder, and he reads every inquiry that lands on this page. He speaks English, Portuguese, French, Spanish and Mandarin. The people behind him are not a call center. They are the engineers and operators on a 6,800 m² floor in Hengli, Dongguan — more than 100 staff, in the same building since 2006 (Zhuohang). When you ask a technical question, it gets answered by someone who has run that process, not by someone reading a script. Factory address, for visits and courier labels: No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470. NDA & IP Your design is the asset. We treat it that way. We sign a mutual or one-way NDA on request before you share anything, and we will hold off on asking for files until it is in place. If your compliance team has a preferred NDA, send it — we sign standard terms and flag only what genuinely conflicts. Storage. Customer IP sits on encrypted digital storage and in locked physical storage. Access is limited to the engineers running the job. No reuse. We do not repurpose your tooling for another customer, and we do not show your parts to anyone outside the project. On your terms. One-way or mutual, yours or ours — the NDA is a formality we are happy to complete, not a negotiation we drag out. Tariff & shipping support Shipping and duties are where a good quote becomes a bad surprise. We would rather tell you the truth up front than win the order and lose you at the dock. Incoterms, stated plainly. We quote FOB, EXW or DDP and we are clear about what each covers and what it leaves to you. FOB hands freight and insurance to you once the goods pass the point of loading; EXW leaves everything from our dock onward to you; DDP puts door-to-door cost and import duty on us. We will tell you which one actually saves you money at your volume, because the answer changes with the shipment. HTS classification. We help you classify parts under the correct Harmonized Tariff Schedule code and provide the certificate of origin your entry needs. The classification is yours to confirm with your broker, but we do not leave you to guess it alone. Paperwork. Commercial invoice, packing list, certificate of origin, and the test or conformance documents your product requires — we prepare the export set and keep it consistent with what the quote promised. One thing we will not do is quietly mark a lower value on the invoice to save you duty. That saves money today and creates liability the moment your shipment is audited. If you want to optimize duties, the legal levers are classification and origin, and we will help you document both correctly. Certifications & where to verify them What we hold, with the certificate numbers, so you can verify rather than take our word. CertificationScope and reference ISO 9001:2015Quality management. Certificate 116024/A/0001/UK/En, issued by URS, valid to 2027. IATF 16949:2016Automotive quality. Certificate 131941/A/0001/SM/En. Scope excludes clause 8.3 design, so we build to your released design rather than claiming design authority. ISO 14001:2015Environmental management. Certificate 116024/B/0001/UK/En, issued by URS. Verify the standards at the issuing bodies: the ISO 9001 and ISO 14001 requirements are published by ISO, the IATF 16949 scheme by IATF Global Oversight, and the Incoterms rules by the International Chamber of Commerce. Our statistical process control is live rather than a wall chart: the last reported Cpk for a critical machined dimension was above 1.67. The factory is a 6,800 m² site in Hengli, Dongguan, running since 2006 (Zhuohang) with more than 100 staff. What this means for your order: ISO 9001 is the baseline your auditor will ask about; IATF 16949 matters if you sell into automotive supply chains and need the process discipline that comes with it; ISO 14001 matters if your own compliance team checks environmental management down the chain. The scope exclusion on our IATF certificate — clause 8.3, design — is deliberate and disclosed: we build to your released design, and we do not claim a design authority we do not hold. Frequently asked questions How fast do you respond to a quote request?Within about one business day. A simple machined part can come back faster; a full BOM with supply-chain checks may take a day or two. The reply is a quote or a short list of the questions standing in the way, never a generic acknowledgment. What if my design is not finished?Send what you have — a sketch, a partial BOM, a CAD model with open items. We give DFM feedback on the parts that are defined and a plan for the rest, so the design closes in a direction that is buildable. Do you sign an NDA?Yes, on request, before you share files. Customer IP is kept on encrypted digital and locked physical storage, and access is limited to the engineers running the job. Can I visit the factory?Yes, in Dongguan. When travel is not practical we run remote audits with live video and share the documents you would review on site. What are your MOQs?None. A single prototype is a valid order. The quote covers the bracket you are actually buying, not a minimum batch we invented. What lead times should I expect?We quote in three brackets — 3, 7 and 30 days — matched to part complexity and component supply. The quote fixes which bracket your job falls into. What files do you need?Mechanical: STEP, IGES, Parasolid or DXF, plus a toleranced drawing. Electronics: Gerbers, a BOM and a pick-and-place file. Send both if the enclosure and the board meet. Do you handle shipping and customs?We quote FOB, EXW or DDP and prepare the export paperwork — commercial invoice, packing list and certificate of origin. We help with HTS classification; your broker confirms it. What tolerances can you hold?It depends on the feature, material and process. The quote states the tolerance we will hold, and our SPC tracks it in production rather than on paper. Do you support EVT, DVT and PVT?Yes. We build engineering and design-validation units, then lock the process at PVT with a first article and, where required, a PPAP package. Can you match a price I already have?Send the quote you have and we will tell you honestly whether we can meet it and where the difference comes from. Sometimes the gap is a tolerance we will not fake; more often it is a bracket or a supply assumption we can match. Either way you get a straight answer. What is a first-article inspection, and do I get one?A first article is a dimensional and visual check against your drawing before volume ships, with a report you can file. It is standard on our production orders and available on prototypes if you ask. It is how the process gets locked to the specification. Do you build a single prototype before I commit to volume?Yes. There is no minimum order, so one board or one machined part is a valid order and a sensible first step. You validate the part, then we ramp the same line to volume.
