Quick-Turn Prototyping

Our dedicated prototype CNC division has the capacity to deliver large quantities of top quality CNC machined prototypes rapidly. Available prototype equipment includes 3, 4, and 5axis machining and advanced turning capabilities to provide comprehensive solutions to an array of industries.


We manage many external processes such as heat treatment, anodizing, coating, welding and standard parts procurement. So We can provide quick turnaround prototype parts in a matter of days, taking your prototyping needs from concept to fruition in a wide range of materials.


We combine our extensive advanced manufacturing expertise with our proven design for manufacturing process to cost effectively deliver prototypes with complex features including challenging surface finishes and tight dimensional tolerances, often much less than 0.001 inch (0.002mm).


Our climate controlled manufacturing facility includes a full suite of coordinate measurement machines and other advanced inspection equipment making complex part inspection possible in a quick turn setting.

First Article Inspection

First Article Inspection (FAI) is an opportunity to evaluate the manufacturability of a part, ensure completeness of the design documentation, identify design errors, recommend design changes to improve manufacturability, and establish the manufacturing process and supply chain for the part.


Here at Jinyuan, we perform a First Article inspection during the new product introduction process to ensure that raw materials, manufacturing process, external special processing steps are indeed capable of consistently delivering products that meet specifications.

  1. Over the years, we have built recognition as one of China's leading rapid prototype machining services providers. The following factors have contributed to our success:
  2. Shorter lead times. Our technical expertise, first-class equipment and advanced inspection systems let us turn around parts quickly. Challenge us with your delivery requirements.
  3. Constant collaboration. Our team will engage you when we see opportunities to improve the deliverable to move projects forward, including design-for-manufacturability services, drawing and model updates, and excellent communication.
  4. Low-volume production. Our quick-turn capabilities extend to lower production volumes. Whether batch sizes of 1 or 100, we can help.
  5. Multi-discipline processing. We manufacture complex parts quickly and cost - effectively - even those that involve multiple processes like milling, turning, EDM, grinding, precision welding, 5-axis machining, and complex assemblies.
