Rapid Prototyping Services for Production-Ready Parts
Validate your design quickly and move from prototype to production with one manufacturing partner.
Custom rapid prototyping for plastic, rubber, and metal parts. Select from suitable manufacturing processes based on your prototype requirements, then continue to tooling, pilot production, and mass production after design validation.

From Prototype to Production With One Manufacturing Partner
Rapid prototyping is part of a broader manufacturing process. For products that will eventually require larger production volumes, the prototype should be evaluated with the final manufacturing requirements in mind.
Prototype With Production in Mind
Consider material, tolerances, geometry, assembly, surface finish, and intended production process during prototype development.
One Manufacturing Partner
Continue from prototype development to tooling, pilot production, and mass production without transferring the project to another supplier.
Flexible Production Volumes
China's injection molding supply chain supports projects across different production stages, from prototypes and pilot runs to low-, medium-, and high-volume production.
Scalable Manufacturing
Support the transition from individual prototypes and small batches to production volumes.
Rapid Prototyping Processes
CNC Machining
For precision prototypes requiring production-grade plastics or metals.
Best for: Functional testing · Tight tolerances · Metal parts · Engineering plastics
Injection Molding
For prototypes that need to closely represent molded production parts.
Best for: Production-grade plastics · Appearance validation · Assembly testing · Pre-production validation
Compression Molding
For rubber prototypes that need to replicate the material and molding characteristics of production parts.
Best for: Rubber parts · Seals & gaskets · Elasticity testing · Functional validation
Prototype Materials
Material selection can consider both prototype testing requirements and the material planned for production.
What to Consider Before Starting Rapid Prototyping
Before starting a prototype project, define what the prototype needs to prove and how it will be used. These requirements help determine the appropriate manufacturing process, material, finish, accuracy, and prototype quantity.
Key Factors to Define
Validation Goals
Define what the prototype needs to prove, such as overall design, fit, function, assembly, or production feasibility.
Material Requirements
Specify required strength, flexibility, heat resistance, chemical resistance, or other application-specific properties.
Dimensional Requirements
Identify critical dimensions, tolerances, clearances, and mating interfaces that need to be controlled.
Surface Requirements
Define required surface finish, texture, color, or appearance.
Part Complexity
Consider geometry, undercuts, inserts, multiple components, or assembly requirements that may affect process selection.
Prototype Quantity
Determine the number of prototypes or small-batch parts required for testing.
Production Requirements
Consider whether the prototype should use the same or similar material and manufacturing process planned for production.
Development Timeline
Define the required prototype quantity and target lead time.
If you are unsure which process is suitable, Jiangzhi can review your CAD files and requirements and recommend an appropriate prototyping approach.

Once the prototype is manufactured, Jiangzhi evaluates it against the requirements defined for the project. Validation covers dimensions, assembly, function, material performance, appearance, and production readiness to identify potential issues before tooling or production.
Submit Your CAD for Prototype Evaluation

Will you sign an NDA to protect my design?
Yes, if you'd like one. A lot of first-time clients ask about this before uploading anything. We're happy to sign your NDA, or send you ours, before you send over your CAD files. Your design stays confidential.
Do I pay for tooling again when moving to production?
No, you won't pay twice. We handle the tooling ourselves, so once you place your prototype order with us, we'll waive the mold cost when you're ready to move to mass production. That's just how we work with our clients.
What happens if the first prototype doesn't pass testing?
That's actually the point of prototyping — catching it before tooling. If it doesn't perform the way you expected, we go back to the CAD, adjust based on what the test showed, and run another round. Most projects need one or two rounds before the design is production-ready — that's normal, not a failure on either side.
Can I order just a prototype without committing to a production order?
Yes, absolutely. Prototyping and production are separate steps for us. Order a single prototype, test it, and decide later — there's no obligation attached to the prototype order.
Can I talk directly to an engineer, not just sales?
Yes. Your project is handled jointly by a sales contact and an engineer from day one. Sales coordinates your order end-to-end, while the engineer handles DFM topics — wall thickness, draft angles, tolerances — so technical questions get answered accurately, especially before a tooling decision gets made.
CNC machining vs. injection-molded prototyping — which one should I choose, and is it worth the extra cost?
CNC machining is faster and more cost-effective — the right call for early fit checks or showing a design to a customer, even for just a few parts. Injection molding costs more upfront, but if you need to validate real production material behavior, it's worth it even for a small batch. Not sure which fits your part? Just send us your design and we'll tell you straight.
Can prototypes be shipped internationally? Who handles customs?
Yes, we regularly ship prototypes to the US, Europe, and elsewhere. We usually use DHL/FedEx for samples and handle the export paperwork on our end — import clearance depends on your country's rules, and we can advise based on what's worked for past clients shipping to your region.
