CNC Prototype Manufacturing Services
JADE-CNC supports CNC prototype manufacturing for metal and plastic parts that need drawing review, material selection, machining feasibility checks, surface finish planning, and inspection before production. Prototype projects are reviewed by part function, geometry, tolerance, quantity, finish, and the next step toward low-volume or production machining.
Prototype Manufacturing in Metal and Plastic
Choose CNC machining and sheet metal fabrication when prototypes need functional geometry, material behavior, fit checks, surface finish review, and inspection feedback before production.
CNC Machined Metal Prototypes
Metal prototypes are useful when a part must be checked for strength, assembly fit, heat transfer, surface finish, or production feasibility. JADE-CNC reviews the drawing, material grade, tolerance notes, finish requirements, and inspection scope before quoting prototype parts.
CNC Machined Plastic Prototypes
Plastic prototypes help teams evaluate weight, insulation, wear, fit, and appearance before production. Material choice is reviewed against geometry, tolerance, wall thickness, machining risk, and expected application.
What JADE-CNC Reviews Before Prototype Machining
Drawing and 3D CAD Files
We check 3D models, 2D drawings, critical dimensions, threads, holes, datum references, and notes that affect machining or inspection.
Material and Function
Material choice is reviewed against strength, weight, heat, wear, corrosion, insulation, and prototype testing purpose.
Tolerance and Fit
Mating faces, bore positions, flatness, wall thickness, and assembly features are checked before confirming the machining plan.
Surface Finish
Finish needs such as anodizing, polishing, bead blasting, passivation, painting, or cosmetic faces are reviewed before production.
Inspection and Next Step
JADE-CNC confirms inspection points and records so the prototype can support design validation, low-volume production, or design revision.

Factors to Consider When Choosing Metal or Plastic Prototypes
Selecting the right prototype material depends on function, load, temperature, weight, finish, quantity, cost target, and the features that must be inspected before production.
|
Factor |
Plastic |
Metal |
|---|---|---|
|
Strength & Toughness |
Suitable for low to medium loads, nonstructural parts, or prototyping. |
High strength and toughness, ideal for loadbearing, structural, or dynamic applications. |
|
Temperature Resistance |
Generally limited to 80 °C–150 °C (some highperformance plastics can exceed 200 °C). |
Can withstand high temperatures over the long term (typically above 300 °C). |
|
Wear & Corrosion Resistance |
Moderate; requires enhanced materials (e.g., nylon, PEEK) for better performance. |
Excellent (especially stainless steel, titanium), suitable for harsh environments. |
|
Electrical/Thermal Conductivity |
Mostly insulating, low thermal conductivity. |
