How do you reach the team?
There are two reliable channels, and both go to the same person — Felipe Iglesias, the business development director. Email [email protected] for drawings and documents, or call / message +86 13126536955 for a quick question or a WhatsApp conversation. The team works in English, Portuguese, Spanish, French, and Chinese, and Japanese, so the first contact does not have to be in translation.
Why the contact matters: the person on the other end has a technical background — enough to read a drawing and flag a tolerance problem before it becomes a cost. When a request arrives, the first response is usually a set of questions about the print, not a price, and that is a good sign.
What should you include in your first message?
A complete first message is the single fastest way to a useful quote. Incomplete requests produce a round of clarifying emails that adds days to the timeline. Send these five things and the review can start immediately:
- A 3D model — STEP or IGES is ideal; the geometry is what gets priced.
- A toleranced 2D drawing — the tolerances are where the cost lives, so the print matters as much as the model.
- The material grade — "6061-T6", not "aluminum".
- Quantity — per order, plus the expected annual volume if you know it.
- Surface finishing — as-machined, anodized, plated, or painted; this changes both price and lead time.
What happens after you send a drawing?
Every drawing goes through a design-for-manufacturing (DFM) review before it is priced. That is deliberate, and it is the part of the process that protects your budget. The review checks each feature against the process that will make it, and returns two things together:
- A quote — based on the drawing as sent.
- Cost notes — flagging any features that are driving the price, and any tolerances that could be loosened without changing function.
The point of the review: a shop that quotes blind is pricing your drawing, not your part. A shop that runs a DFM review is pricing the part as it should be made, and telling you where over-specification is costing you money. The quote comes with those notes attached, and acting on them is optional.
How do you prepare a drawing that keeps cost down?
Before you hit send, run the print through the same filter the DFM review will: tolerance only what controls function. The most expensive habit in machining is a blanket tolerance — one tight band stamped on every dimension. The fix is to ask, feature by feature, whether the function survives a looser band.
- Reserve ±0.002 mm for ground features — bearing seats, journals, seal faces.
- Use ±0.003 mm (milling) / ±0.002 mm (turning) for alignment and locating features, milled or turned.
- Relax to a general tolerance for clearance and cosmetic surfaces.
If you are not sure which dimensions are driving cost, send the drawing as-is and ask. The answer will name the specific features — "this bore is ±0.002 because it is ground; this boss could be ±0.1 and save a setup" — and that is the most useful reply you can receive.
What does the quote include?
A quote here is two documents, not one number. The first is the price for the part as drawn. The second is a set of cost notes that explain why the price is what it is, and where it could come down. The table below shows the difference between what you expect and what actually arrives.
| What a buyer usually asks for | What the quote actually includes |
|---|---|
| "How much for these parts?" | A price based on the drawing as sent |
| (implicitly) "and nothing else" | Cost notes flagging features that drive price |
| — | Tolerances that could be loosened without changing function |
| — | A stated lead-time tier: roughly 3, 7, or 30 days |
The cost notes are the part worth reading, because they are where over-tolerancing gets caught before it turns into an invoice. Nothing in them is a hard sell — they are information, and acting on them is optional.
Where is the factory located, and how do you visit?
The facility is in the Pearl River Delta, China's densest precision-manufacturing region:
No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470
Chinese address: 广东省东莞市横沥镇水边松元路8号
Factory visits and audits are welcomed — a visit is the fastest way to confirm what a website claims, and the machine list, CMM bench, and certification documents are all available in person. If travel is not practical, the same evidence ships as documentation with every order.
What languages and response times can you expect?
The sales team works in English, Portuguese, Spanish, French, and Chinese, and Japanese, and overseas buyers are supported directly — there is no hand-off through an interpreter at the quoting stage. On response time: a complete drawing typically gets a quote back within one business day; complex parts take longer because the review is deeper. A quick question sent by email or WhatsApp is answered promptly during business hours.
If a deadline is tight, say so in the first message. The lead-time tiers here are roughly 3, 7, or 30 days depending on complexity, and the honest answer on whether a date holds comes with the quote, not after the order.
What should you watch out for when briefing any supplier?
These briefing habits quietly inflate cost or slow the quote, and they are worth catching before the first message goes out — to any shop, not just this one.
- A vague material callout — "aluminum" is not a spec; 6061-T6 is. Ambiguity forces a clarifying round or, worse, an assumption.
- A blanket tight tolerance — one band on every dimension is the fastest way to double a quote.
- Withholding annual volume — knowing the yearly quantity lets the supplier price the program, not just the first batch.
- No surface-finish intent — as-machined, anodized, and plated are different prices and different lead times.
Fix those four and the quote that comes back will be both faster and closer to the part's real worth.
One more thing worth stating plainly: there is no automated quote form on this site, and that is deliberate. A form that drops a drawing into an unread queue is where requests go to die. Sending the drawing directly to a named engineer means the DFM review starts immediately, and the first reply addresses your specific part, not a template.

Frequently Asked Questions
How do I contact High Precision Machining?
Email [email protected] or call / message +86 13126536955. The sales contact is Felipe Iglesias, and the team works in English, Portuguese, Spanish, French, and Chinese, and Japanese.
What should I send to get a quote?
Send a 3D model (STEP or IGES) plus a toleranced 2D drawing, the material grade, quantity, and any surface finishing requirements. For complex parts, both 3D and 2D files are needed.
What happens after I send a drawing?
The team runs a design-for-manufacturing review, flags any over-toleranced features, and returns a quote with notes on what is driving cost and what could be loosened to save money.
What does the quote include?
A price based on the drawing as sent, plus cost notes flagging features that drive price and tolerances that could be loosened without changing function. Acting on those notes is optional.
Can I visit the factory?
Yes. Factory visits and audits are welcomed at No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470.
How quickly will I get a response?
The team responds promptly during business hours, and quotes typically follow within one business day once a complete drawing is received. Complex parts take longer to review.
Do you sign NDAs?
Yes. An NDA is signed and returned on request, drawings are never shared without written permission, and sensitive data is stored in a secured, access-controlled space.
What should I avoid when briefing a supplier?
Avoid a vague material callout like just "aluminum," a blanket tight tolerance on every dimension, and withholding annual volume. Each of these slows the quote or inflates the price.
