Rapid Prototype CNC Machining in China

What is Rapid Prototype CNC Machining?

Rapid prototype CNC (Computer Numerical Control) machining is a process that uses computer-controlled machines to create precise models and parts from a variety of materials. This technique is essential for testing the form, fit, and function of a design before mass production. The rapid prototype CNC machining process typically involves the following steps:

  1. Design: The creation of a 3D CAD (Computer-Aided Design) model.
  2. Programming: Converting the CAD model into a CNC program that guides the machine.
  3. Machining: Using the CNC machine to cut and shape the material into the desired form.
  4. Finishing: Applying post-processing techniques to achieve the final surface finish.

Key Materials Used in CNC Machining

CNC machining is versatile, allowing for the use of a wide range of materials, including:

  • Plastics: ABS, PMMA (Acrylic), PC (Polycarbonate), and more.
  • Metals: Aluminum, stainless steel, magnesium alloy, brass, etc.

Services Offered by SINO MFG

Services Offered by SINO MFG

SINO MFG is a leading provider of rapid prototyping services in China, known for their expertise in vacuum casting, SLA (Stereolithography), SLS (Selective Laser Sintering), and CNC machining. They cater to various industries by delivering high-quality prototypes with quick turnaround times and competitive pricing.

Vacuum Casting

Vacuum casting is a popular method for creating high-fidelity prototypes and low-volume production parts. It involves making silicone molds from master models and then using these molds to cast parts from polyurethane or other suitable materials. This process is ideal for producing parts with complex geometries and fine details.


SLA and SLS are advanced additive manufacturing techniques used for creating intricate prototypes:

  • SLA: Uses a laser to cure liquid resin into solid parts layer by layer, providing high-resolution and smooth surface finishes.
  • SLS: Employs a laser to sinter powdered materials, such as nylon, into solid parts, offering durability and the ability to produce complex shapes without the need for support structures.

CNC Machining

SINO MFG excels in CNC machining, offering rapid prototyping and low-volume production services. Their CNC machining capabilities are particularly competitive for several reasons:

  • Cost-Effective: Their pricing for CNC prototypes is typically 40-60% lower than that of Western companies.
  • Quick Turnaround: Delivery time for CNC machined parts is usually 7 to 10 days, including 3 to 4 days for air shipping.
  • Quality Assurance: Despite the lower cost, the quality of the prototypes matches that of Western manufacturers.
