Our concept is to make the best custom CNC machining parts from the beginning!
Free evaluation of precision CNC machining
Propose your idea or 3D or CAD files, and we will start your project for free evaluation immediately. Our goal is to complete the quality and cost-effective plan for your parts within 30 minutes.
DFM analysis
Before custom machined components parts starting production, we will execute DFM analysis and develop a process control plan for all quality risk points. Our engineers will program based on DFM risk points, and then arrange tools and cutter to ensure the consistency of part quality.
During the precision machined parts production process, our QC engineers will conduct patrol inspections based on the engineering drawings, and follow certain test methods and frequencies to ensure that the quality meets the requirements of the drawings (appearance, dimensions, tolerances).

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.
2021-04-06The dimensions are all customized according to my drawings no tolerance issues and the parts are delivered on time. I am very satisfied with it.
2021-05-13I 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.
