Prototype machining & Manufacturing process details

Various raw materials for rapid prototypes are in stock, such as steel, stainless steel, copper, plastic, and aluminum alloys.

Best and effective manufacturing solutions with perfect CNC machining program
Selecting suitable raw materials for prototypes depends on the prototype’s purpose and customer requirements. Our skilled prototyping engineers makes a production plans based on the prototyping process, including CNC milling, turning, and other processes like laser cutting and EDM, etc.

We offer fast CNC milling for plastic prototypes using high-speed CNC machining centers, with deviations ranging from ±0.005 mm to ±0.01 mm.

CNC turning rapid plastic prototypes (MOCK-Up)
Fast custom manufacturing with CNC machining centers and lathes. Tolerance range: ±0.02 mm. At JINGXIN, advanced high- performance CNC machining centers enable rapid prototyping, with a machining capacity for workpieces up to 1.5 m × 1.2 m × 0.8 m. SLA printing prototype lead time: 1-3 days; CNC rapid prototype lead time: 3-6 days.


Handmade and surface polishing
Before proceeding with rapid prototype surface treatments like painting or plating, all prototypes are assembled and inspected piece by piece by our machinists after the initial CNC machining process. The surfaces are then hand-polished or machine-polished according to client-specified treatment requirements.


Surface treatment
We perform surface treatments in-house, including spray painting, powder coating, electroplating, and vacuum plating for plastics. For more available finishes for prototypes, please refer to the Finishes page.
