CMF
Color, Material, Finish – Multi-Functional Evaluation Part
The CMF Evaluation Part = a “magnifying glass” for design validation.
Beyond visuals — it’s real touch and perception.
CMF engineering helps hardware teams validate materials and processes faster, reducing errors before production begins.

CMF makes real materials and finishes visible early in the design process.

Injection Molding CMF Sample Kit
Every material reacts differently in molding
- Compare multiple plastic materials in one test kit
- Visualize CMF outcomes directly from real injection molding
- Reduce retooling costs and validation time
- Accelerate CMF and design decision-making
The Injection Molding CMF Test Kit by NexPCB enables designers and engineers to visualize and evaluate the real behavior of plastic materials under injection molding conditions.
It includes 11 material and process combinations, offering a quick and cost-effective way to compare performance, texture, and appearance without extensive testing cycles.
This kit helps hardware teams understand key properties — such as flowability, shrinkage, surface finish, gloss, and transparency — supporting smarter material and process selection in early product development.
Included Materials & Processes:
| PC+BAS (Black) | PA6 (Black) | PA6+GF (Black) | PA6+CF (Black) |
| ABS (Black) | PC (Black) | PP (Black) | PC+ABS (White) |
| POM (White) | ABS (Transparent) | PP (Transparent) |
Material, Design, Supply Chain & Risk Prediction
Material Selection
Visually compare the flow characteristics and surface finish of different materials.
Supply Chain Evaluation
Standardize part specifications to rapidly screen suitable suppliers and material grades.
Structural Design Optimization
Identify how wall thickness, hole placement, gate locations, and other factors impact performance.
Risk Prediction
Identify and mitigate potential defects before mass production.
Design For Injection Moulding
Mold Flow Analysis Simulation
Verify gate location, simulate filling behavior, warpage tendencies, and weld line positioning → Ensure design feasibility.
Actual Injection Molding Validation
Confirm transparency, ejector marks, weld lines, and short shots → Simulate real mass production conditions.
CMF Key Test Areas
Tip: See part photo with A/B/C/D zones highlighted
A. Flowability Test
Flow filling capability at different wall thicknesses → Determines susceptibility to short shots and air marks.
C. Boss forming reliability
Impact of boss structure on appearance→ Evaluation of reliability and defect risk
B. Surface Texture Test
Texture comparison → Evaluates material performance under gloss and reflection effects.
D. Weld Line & Hole Evaluation
Detect susceptibility to weld lines, out-of-roundness, and flash in through-hole structures.
