Frequently Asked Questions

In order to quote for you earlier, please provide us the following information along with your inquiry.


1)-Drawings (in PDF/CAD/DWG/STEP/IGS/JPG format)




3)-Surface treatment


4)-Any other special requirements, such as particularly tight tolerances, customized packaging and labels, urgent lead time and so on.

Although straight comparisons are not easy, HFJ's quote will be usually 70-80% less for CNC machined parts when compared to vendors in North America as well as Europe. Of course, what we are saying is based on the same quality, not on cutting corners.


This cost superiority benefits from China's unique labor advantages and the convenience of various material resources mobilization as well as very developed logistics.


Compared to other Chinese suppliers, we choose not to compete just on price,but to provide top quality, efficient& pleasant communication and our special one-stop service.

Most of the time, we respond within 24 hours of receiving the RFQ. If the quote is likely to be delayed, we’ll inform you immediately.

8)-Silk Screen Printing


Learn more on our Surface Finish page.

There are mainly 4 steps.


1)-Incoming Materials Check


2)-In-Process Quality Check


3)-Semi finished products inspection prior to surface treatment


4)-Final Product Quality Check prior to packaging

We file drawings and test reports well in case for future reference, if you find any doubts after receiving parts, please contact us at the very first time, we’ll provide you solutions within ASAP.

It depends on the complexity of designs, surface finish, packing methods and quantity.


If your project is very urgent, we can adjust our current production flexibly and prioritize your job accordingly.


Usually 2 to 4 weeks could be a reference to samll orders.

If have to say one, then the minimum tolerance is ± 0.00025 in. We don’t have a given set of tolerances that apply to all processes and materials. However the true case is that final tolerances will depend upon several factors, including but not limited to:


-Manufacturing process




-Design features


-Surface finish


-Parts size


Anyway, we analyze case to case. We’ll evaluate your drawings and requirements, and point out any areas where we are unable to meet your desired tolerances. At this point, it would be very helpful if you could indicate which tolerances must be met and which can be changed slightly in order to reduce machining time and costs without affecting their functionality.


It would be easier to both us, if all manufacturing and technical specifications to be followed are clearly specified in the 2D drawings.

Firstly, we can sign mutual non-disclosure agreements and will certainly adhere to it.


Additionally, we have strict policies in our company that no photos of a customer products will be disclosed after signing NDA.


Lastly, we value our reputation, ever collaborated with thousands of unique designs over years and never ever allow any type of proprietary information to be disclosed to 3rd party.

Max milling size: 1500*800*800mm


Max turning size: φ500 * 100mm,  φ300 * 500mm,  φ10~40 * 300mm


Automatic CNC longitudinal lathe max size: <φ20 * 400mm.


We renew our equipments from time to time, pls contact us for most recent updates.

According to products’ shape and surface requirement, we provide various packing choices, Check Details.


Of course, customized packing methods are welcomed!

There is no single answer to this question.


Import tariffs vary greatly from country to country and depend on the type of imported goods. The commodities of most countries in the world conform to the International Harmonized System (HS) codes, which classify almost all commercially traded goods.


If you are very concerned about this, please let us know the usage, name and HS code (if you know) of the parts, then we’ll pre-check import duty for you.
