- Material type (plastics, metals, composites)
- Desired surface finish
- Functional requirements and tolerances
2. Find an Ideal Prototyping Partner
- Research and identify reputable companies in China that specialize in rapid prototyping.
- Look for organizations with strong communication skills, proven quality, advanced equipment, and experience with your type of product.
- Request samples or view a portfolio of completed projects.
3. Request Quotation and Feasibility Feedback
- Submit your designs and requirements to your chosen Chinese prototyping firm.
- Ask for a detailed quotation, including lead times, estimated cost, and recommended manufacturing methods.
- Ensure your partner reviews your design for manufacturability and suggests improvements if needed.
4. Manufacturing the Prototype
Depending on your specifications and the prototype’s purpose, your partner may use:
- 3D Printing (Additive Manufacturing)
- Quick turnaround for plastics and some metals
- CNC Machining
- High accuracy, suitable for metals and functional plastics
- Vacuum Casting
- Useful for small batches and simulating production plastics
- Sheet Metal Prototyping
- Great for enclosures and structural parts
Your prototype manufacturer will fabricate the parts, frequently updating you on progress.
5. Post-Processing and Quality Inspection
- After fabrication, parts are finished as required (sanding, painting, anodizing, etc.).
- The company will carry out quality checks to match your specs.
- Photos and videos may be shared before shipping to confirm quality.
6. Delivery and Feedback
- Finished prototypes are carefully packaged and shipped.
- Typical international shipping options include express courier or freight, depending on part size and urgency.
- Once received, you evaluate the prototype, test its fit, function, and appearance, then provide feedback for revisions if necessary.
Key Benefits of Prototyping in China
1. Cost Effectiveness
- Labor and operational costs in China are generally lower than in many Western countries.
- Prototyping companies often buy materials and supplies in bulk, reducing costs.
2. Fast Turnaround
- Many firms offer turnaround times of just a few days to a few weeks, even for complex parts.
- Round-the-clock operation helps meet tight development deadlines.
3. Advanced Technologies
- Chinese manufacturers invest heavily in the latest rapid prototyping equipment, including multi-material 3D printers and 5-axis CNC machines.
4. Full-Service Solutions
- Many firms provide a one-stop-shop, covering design review, prototyping, testing, and even low-volume or mass production.
- Some can also assist with assembly, packaging, and shipping.
