How it works
Simple steps from upload to delivery
1
Send Your CAD Files
Provide CAD files, BOM lists, assembly requirements, purchased component information, and project objectives for review.
2
Engineering Review
Our engineering team reviews product structure, assembly sequence, material selection, and manufacturing feasibility.
3
Prototype Part Manufacturing
Plastic components are manufactured through CNC plastic machining, vacuum casting, or 3D printing.
4
Component Preparation
Customer-supplied components and standard hardware are prepared and organized for prototype assembly to ensure smooth integration.
5
Surface Finishing
Painting, silk screening, UV coating, polishing, and other finishing processes are applied to achieve the required prototype appearance.
6
Trial Assembly
Prototype components are assembled to verify part fit, structural alignment, fastening methods, and overall assembly requirements.
7
Assembly Verification
The completed prototype assembly is reviewed to confirm component compatibility, appearance quality, and readiness for engineering evaluation.
8
Final Inspection & Delivery
Completed prototypes are inspected, packaged, and shipped for evaluation and testing.
Surface Finishing
We offer 6 surface finish options for your CNC prototypes and full production parts. Our extensive options allow you to match finishes to your parts’ specific requirements and applications.
Natural Finish
Natural finish removes burrs and machining marks while preserving the original color and texture of the raw material, providing a clean and functional surface for engineering prototypes.
Painting
Painting provides smooth cosmetic finishes with customized colors, textures, and surface effects for appearance prototypes and production-like parts.
Electroplating
Electroplating applies a metallic coating to plastic parts, improving appearance, wear resistance, and production-like surface quality.
Silk Screening
Silk screening is used to apply logos, graphics, and functional markings onto prototype surfaces with high clarity and durability.
UV Coating
UV coating enhances surface gloss, scratch resistance, and cosmetic durability while improving the overall appearance of prototype parts.
Water Transfer Printing
Water transfer printing enables complex patterns and decorative textures to be applied to curved and irregular prototype surfaces.

Prototype Build Services FAQs
What Is Prototype Build?
Prototype build is the process of assembling individual components into a complete physical product for testing, evaluation, and demonstration.
What Types of Components Can Be Assembled?
We can assemble CNC machined parts, vacuum cast parts, 3D printed parts, electronics, and purchased hardware.
Do I Need to Supply All Components?
No. Customers may provide components, or we can assist with sourcing standard hardware and accessories.
Can Prototype Build Include Functional Testing?
Yes. Basic functional verification can be performed according to project requirements.
How Many Prototype Units Can Be Built?
We support both single-unit prototypes and low-volume prototype assembly projects.
Why Use Prototype Build Before Production?
Prototype build helps verify assembly methods, component compatibility, appearance, and functionality before production investment.
