CNC Turning FAQs
Are your materials standard?
We all use new and standard materials, not secondary recycled materials. Our material composition is standard and we can provide third-party test reports from SGS, CTI, TUV, etc. Please see the attachment.
What is your MOQ? Can you do small batch proofing/ small quantity?
Order quantity can start from 1pc. Any big order starts from a small order, just like a baby, it needs to grow step by step. Another more important reason is that in the current economic situation, orders from all indutries tend to be in small batches. If we give up small batch orders, we will give up the entire market. Accepting small batch orders is one of the necessary conditions for a company's future survival.
How long is the sample delivery time?
We accept the sample order if need to test before mass production. 1 pcs or 2 pcs or 10 pcs.... is okay. VMT sets two sampling teams at the sample stage, finish samples 24 hours a day, make complete sample records and keep them for one year. The sample fee will be refunded after mass production.
Is your quality stable?
We use an advanced quality control system, equipped with manual and automated inspection equipment. All reports are archived and kept for two years, such as first article inspection, process inspection, and shipment inspection. From raw materials, CNC processing to shipment, We have dedicated personnel to follow up and share progress in real time. We have a testing laboratory equipped 2D projector, 3D projector and other high-precision testing instruments.
What inspection equipment do you have?
We have a testing laboratory equipped with three-dimensional, two-dimensional, projectors and other high-precision testing instruments.
Can you sign NDA?
Yes, we can sign NDA, do not disclose drawing and design, because we know that every design is important for each company. All customer drawings are kept in the business department and NDA is signed. Only disassembly drawings are used inside the factory, and there are regulations not to forward any videos and pictures of customers on public platforms. Do you have any other comments to add?

The manufacturer is strongly recommended. In the past few years of cooperation we have ordered several machined products from aluminum and stainless steel. These products are manufactured in compliance with tolerance requirements and require product finish. Now I have ordered another one. The service is excellent and any questions can be answered and resolved in time.
2021-05-13
The dimensions are all customized according to my drawings no tolerance issues and the parts are delivered on time. I am very satisfied with it.
2021-04-06
I pay much attention to the surface treatment aspect of this product. I was a little worried about the cooperation at the beginning. I am very satisfied with the product now and hope to cooperate for a long time.
