How to Select the Best CNC Machining Services in China?

Why Work With An External CNC Machining Shop?

So, why should a company turn to external computer numerical control manufacturers for their CNC needs? There are a couple of reasons.

If you want to learn more, please visit our website LECN.

First, CNC machining is expensive because you have to factor in the cost of acquiring top-notch CNC machines, industrial equipment, and other post-processing systems. Hence, deciding to take on these costs as a small or medium-sized business before production would increase the cost of the manufacturing process out of proportion.

However, by working with an external CNC machining shop, you would not have to invest heavily in purchasing machinery before reaping its technological benefits.

Another reason businesses should work with external CNC machining shops is to save training and labor costs. The machining process of custom CNC machining is quite complex and often requires the expertise of a professional team of operators.

For a company to engage in CNC milling in-house, it must employ an expert CNC machine operator, increasing the labor cost. However, outsourcing the job to external machining shops means that the company would not have to take on additional labor or training costs before benefiting from CNC milling services.

Why Outsource CNC Machining Services to China?

Manufacturers and businesses worldwide now outsource their rapid prototype and CNC machining services to China. So, why CNC machining in China? Here are some reasons why china's CNC machining services have become a popular destination for CNC machining.

Top Notch Communication and Technologies

Top-notch communication and technologies

The popular argument against outsourcing to China is distance and the inability to track CNC machined parts easily. However, this is no longer the case with the rapid advancement in communication and internet technology. Businesses can easily track their CNC machined part orders, resulting in high-speed turnaround time.

Higher Profit Margin

Higher profit margin

Compared to most western manufacturing companies, outsourcing 3D printing, rapid prototyping, and CNC services to China has a higher profit margin while helping you achieve the desired shape. This higher profit margin is due to the lower cost of labor and raw materials compared to the west.

Intellectual Property Protection

Intellectual property protection

Additionally, there is no risk of intellectual property theft when businesses hand their designs to Chinese CNC machines shop for production. The reason is that China's CNC machining has improved its intellectual property laws, offering protection to all customers and businesses.

High-Quality Production Parts

Another reason why outsourcing online CNC machining services to China is the quality of the parts produced. The skill level in the Chinese CNC machining services sector is very high.

The popular belief is that low labor costs equal low skill, not in this case, as Chinese CNC manufacturers produce CNC machined automotive parts that meet and surpass industry quality standards.

One way to guarantee the production of quality parts is by partnering with experienced and reputable custom CNC machining shops like AT-Machining. Other tips to ensure high-quality CNC machining parts include;

  • Inspecting components upon delivery and reporting any concerns or issues discovered immediately.
  • Keep communication lines open throughout the project. This would make it possible for you to change your computer-aided design for CNC machining or for the shop to reach you if issues arise with your product.
  • Also, when choosing a CNC machining factory, it is often best you request previous works done by the service provider. This would give you a general idea of the kind of quality to expect.

Having examined the general benefits of working with a CNC machining China-based company, the next item on the list is choosing the right CNC machines shop.

Produce Finishing Services

Unlike their western counterparts, China-based CNC machine shops offer their clients various finishing services. These services range from plating, powdered paint, and bead-blasting to black oxide and polish. This finishing service improves the material's corrosion resistance. It is often helpful to businesses that require a specific finish for their CNC machining parts.

How to Choose the Right CNC Machine Shop In China

Choosing the right CNC machining China-based shop guarantees you top-quality CNC machined parts/components at lower costs. Are you looking to head into the Chinese CNC machining market? Here are some tips for choosing the right CNC machine shop.

Process and Quality Control

One way to check a CNC machine shop's bias to quality control is the robustness of their product testing and verification process. When choosing a company, ensure you choose one with traceable bar codes or serial numbers.

In the interest of transparency, you should request testing reports before shipping to ensure manufactured CNC part meets industry standards like the automotive industry, semiconductor industry, and medical industry.

Additionally, top-quality companies like AT-Machining take machining process control seriously, using the right cutting tool. Besides, it assures you 100% strict part inspection, ensuring all management materials and techniques are optimal.

Certifications

Checking a company's certifications remains one of the best ways to assess its credibility, especially for CNC precision machining shops. Besides, checking the certifications also helps you ascertain if the company you are checking out is the best fit to produce the quality and type of product you want.

For instance, if you are producing for the medical industry, then the CNC machine shop you choose should have the right industry certification. This certification guarantees that medical devices or other products produced in the CNC machine shop would meet the medical standards.

Manufacturing Capabilities and Experience

We cannot overstate the role of experience in the manufacturing industry. When choosing a CNC machining shop, you should go for one that has been in business for several years. The reason is that they often have the right skill and knowledge to avoid production process complications and solve any that arises during production.

Also, asides from general manufacturing solutions experience, it is best to ensure the company has experience working with your chosen project material, be it plastic or metal materials.

Coupled with experience, the ideal shop should also have the right advanced equipment and production capacity to fulfill your order. This includes but is not limited to multi-axis machining systems, CNC turning, and milling machines.

Customer Service and Communication

Customer service and communication

Thanks to technological advancement and the internet, it is now easier to communicate with China-based CNC machining shops. Communication is crucial to the success of a project. Without proper communication, a manufacturer might not understand your project needs, leading to project failure.

If there is something you do not understand, it is always best to ask for clarification. This doesn't only apply to CNC machining, but also to 3d printing, injection molding, and rapid prototyping projects.

Run A Machining Test

Most Chinese machining companies have an MOQ (Minimum order quantity). This represents the smallest quantity of products you can order from the supplier. There are several benefits to ordering a smaller batch of products from a new supplier.

  1. It protects your interest, ensuring you do not waste money ordering many defective products.
  2. The second point, it allows you to test the product's functionality.
  3. An MOQ allows you to test if the product ordered meets industry-high precision standards and quality.
  4. It enables you to check the machining shop's turnaround time.

When choosing a China CNC machining company, you should choose one with a low MOQ.

Pricing and Turnaround Time

Pricing is a crucial aspect of the CNC machining process, so when choosing a shop, ensure you are getting a fair price. Comparing prices from different sources is one way to ensure you get a fair price.

Also, always go for companies that can provide you with a quick turnaround time. This feature is important for ensuring you complete your projects on schedule without blazing past deadlines.

27 Questions To Ask During A China Factory Visit

An in-person factory visit to your Chinese supplier's facility is a great opportunity to get a deep understanding of who they are and if they're capable of fulfilling your requirements. Your factory visit should be a fact-finding exercise rather than just an opportunity to passively write down some notes on what you see.

Let's explore some of the key questions you should be asking during your factory visit.

Using Your Eyes & Ears In The Factory

No doubt before you've gotten to the stage of visiting a supplier's factory, you've already performed due diligence on them to ascertain that they're legitimate. During this research, you should be able to find out a lot of helpful information that can confirm that they're a capable supplier (and a real manufacturer), so where does an in-person factory visit fit in?

It's a chance to confirm everything you've already learnt, and more, by using your eyes and ears.

In this episode of our podcast, we discuss the three categories of subjective evaluations you should be making visually when visiting a supplier's factory, including:

  • How good a fit they are for your business
  • Whether their management is up-to-scratch
  • If the conditions in the factory and how it's setup are positive

In addition to the visual assessments outlined in the podcast, you should also be asking the following questions to help you learn even more.

 

27 Questions You Should Be Asking During A Visit To Your Chinese Supplier'

Asking about private/sensitive issues is a bit rude in China. But I often say that, if a supplier gets offended too easily, he is not familiar with export customers' requirements, and you might have problems down the road with his mentality.

Questions about top management and their priorities

  • When was the factory started? What was the previous job/experience of the owner?
  • Is the factory profitable? What were its sales last year? And 3 years ago?
  • What is the latest investment made in the factory, and how much did it cost?
  • What is the next investment they are planning?

Questions about middle management

  • Who will probably follow your order, besides the salesperson? How long have they worked in this factory?
  • How many other orders do they follow?
  • Where do the line leaders and the in-process QC staff come from? Were they promoted internally, or hired from the outside?

Questions about the workforce

  • What proportion of workers came back after the last Chinese New Year?
  • What is the employee turnover rate month over month (excluding the new year period)?
  • What happens when an operator makes a mistake? Is she fined?
  • Are operators paid by the number of pieces? Or by the hour?
  • Is a part of their compensation based on the team's results, or is it all individual?

Questions about the capacity

  • Observe one line that is making about the same product as you intend to purchase. Ask for the output of this one line in one day. Then, based on what you see in a few minutes, calculate whether it makes sense.
  • When the factory was set up, what was the expected (theoretical) capacity?
  • What is the lead time from receipt of all materials/components to full packing?
  • What materials/components do they buy? Do they only do the final assembly and packing, or they also make some components?

Questions about the quality management system

(See more checkpoints in a previous article about ISO factory audits.)

  • How do they control the incoming components? Can you see it?
  • How do they do in-process QC? Can you see it?
  • How do they do final QC? Can you see it?
  • Do they send samples for testing in a laboratory? Can you see the test result for a production batch that you point to them?

Questions about certificates and other customers

  • Who do they work with? Can they give you references that you can call? Do they work directly with these customers, or through an intermediary?
  • Can they show you the latest two purchase orders from a big customer they proudly mentioned to you?
  • Can you see their business and export licenses? Can you take a photo of them to show to your investors?
  • The last time they made a big mistake regarding product quality and their customer found out about it after shipment, what did they offer as compensation?

Questions about payment

  • What is the usual bank that they request customers to pay into?
  • Do they have a Hong Kong account?
  • What are the payment terms?

Get answers to these questions and you'll be far closer to deciding if this potential supplier is the right choice to manufacture your products.

 

The Next Step'A Factory Audit

Your visit to the supplier's factory is really helpful for fact-checking and finding, but there are 2 issues to contend with:

  1. You may not be able to attend the supplier's factory (perhaps you're too busy or there are other reasons preventing you from visiting China such as it having closed its borders to foreign visitors as of now in July ).
  2. You may lack the expertise or knowledge to professionally assess the supplier's capabilities.

This is why factory audits from an expert team are really helpful, as the auditor will assess the supplier's manufacturing capabilities, possible risks, management and organization, and much more, providing a detailed report that will aid your decision.

Even if you cannot get to China to visit the supplier's factory, the auditor will act as your eyes and ears. Also, as mentioned in the podcast episode included here, it's possible to ask the auditor to take a few extra photos of certain areas of interest (such as the conditions that operators work in) or ask some specific questions.
