How To Find A Good CNC Machining Supplier In China
How To Find A Good CNC Machining Supplier In China
As you have known, CNC machining is a basic industry and arguably the most significant manufacturing process. With the functionality, it drivers technological advancement across the world.
As a big manufacturing country, China turns into the world’s leading provider for CNC machining service. Based on a recent report, there are more than 3000 shops in Shenzhen city in China which is an incredible number. Therefore, more and more companies in the world are looking for cnc machining services from China, so it is a hot subject for CNC machining supplier.
RapidDone is one of the professional manufacturing experts in China with more than 10 years of experience, so we know about this whole industry well. Today in this post, we will go over some of the top tips and tricks covering mainly four aspects:
Reasonable lead time
Choose The Suppliers With Good Quality Control Capability
Quality is the most important thing for a product, normally, we can check into the below four to identify the proper one.
1. Take An older CNC Machining Supplier
Generally speaking, an older CNC machining company means more professional and be of more experience in the field. As they have done so many various kinds of projects, they normally have more chances to handle complicated CNC machining projects from material to finish. Milewhile, they know better how to handle quality issues and make quality CNC parts. Therefore, it is always good to choose a factory that has been in the machining industry for more than 5 years.
2. Check If They Have A Good Quality Control System
A good CNC machining factory should have an independent quality department with a QA team for quality check. Inside this department, they need to have basic measuring and testing equipment which normally include CMM, projector, calipers, microcaliper, pin gauge, caliper gauge, etc. In conclusion, a qualified CNC machining manufacturer can do quality control from raw material inspection to final parts checking.
3. Look Into Their Machining And Inspection Equipment
A good shop should have good machines such as CNC lathe, CNC milling machines, grinding machines, EDM machines, drilling machines, tapping machines. In addition, one most important thing is to check if they have a high tolerance 5-Axis CNC milling machine. Because 5-Axis CNC milling machine is a very expensive machine which is can produce complex and high tolerance parts.
4. Check If They Have A Strong Engineering Team
CNC machining is a complex work, it covers material selection, production progress selection, and finishing handling. A strong engineering team can understand your design, help you to make design improvements. This can make it easier for manufacturing and helps to make costs down, thus, make higher quality parts at last. The tip here is that we can send the drawing to the engineer to ask for a DFM report before we move into production.
Select The Supplier With An Affordable Price
You need to know Chinese supplier’s categories first, there are normally have two types of vendors which are manufacturer and trader. Basically, the manufacturer has in-house product development capability, they will have a stronger engineering team, the price is lower but MOQ is higher.
On the other hand, trader supplier is the ones that just buys-in and sells-out, their price for their parts might be higher, but their advantage includes wilder ranger of products, lower MOQ and more adjustable sales support like payment term. The tip here is that it is always good to work with a manufacturer supplier first rather than a trader supplier.
As for the normal procedure for CNC machining price selection, we can talk to more than three suppliers at the same time. Then we move out the ones with “untrusted” price figure ones, do the background check carefully, and source out the best one at last. It becomes so easy to get a quotation for a CNC part in the word now that you can even get a quotation within 1 minute. For an instant, you can get a quotation from an online quotation system like 3d-hubs or Xometry by submitting your drawings from the website.
Search Alibaba.com with keywords is the best option if you want to find a CNC machining supplier in China quickly. We suggest you ignore the one with more than 3 years Gold Supplier. Next, we check out several good ones and send the RFQ at the same time, you normally can get quotation feedback in 24 hours. Then start the comparison work and background checks work, soon you will be able to get the proper one at an affordable price. Keep this in mind, do not go to the cheapest one.
Choose The Supplier With A Reasonable Lead Time
Today, product life is becoming shorter and shorter, so turn around time becomes more and more important too. Normally, there are prototyping build and mass production build. Prototyping is normally used for sample build which is very urgent, we counted them with days. As for volume production, we can accept a longer lead time, two to three weeks is a reasonable timetable.
But this is just a simple benchmark figure, the final lead time depends on the part complexity and especially tolerance. For example, our CNC machining service lead time for prototyping is about 5days, it is less than 3week for mass production.
Anyway, keep this in mind, if a supplier comes out with more than 6 weeks for mass production lead time, don’t go to them.
Use The CNC Machining Supplier With Good Customer Services
After-sale service is very important to judge a good CNC machining factory, especially for custom machining services. Here, you need to check if they have a good follow up after your order release. For example, you can check if they have a close follow up after they ship out the goods.
More importantly, once there is lead time or quality problem, we need to check out if they can follow a good handing procedure. For example, are they professional enough to fulfill your reasonable requirements? Check all these out for the first one or two orders when you start to work with a new CNC machining supplier in China, switch to a new one if the old one performs badly.
CNC machining service is an OEM service, it involves a lot of custom work, which means it does need to take some energy to source a good one.A good machining supplier like RapidDone will be able to keep your money safe and keep your product safe.
