QUALITY SURFACE CHARACTERIZATION REPORT
Quality surface characterization:
1) Visible improvement using Roctool technology are observed: glass fibers are covered on the surface, weld line and sink mark are also removed.
2) These improvements are confirmed by the measurements of the gloss with 81% of improvement. Roctool technology allows to get a piano black
part with a perfect surface finish. No significant impact of Roctool on the color depth.
3) The different textured areas hightlight the positive impact on the replication using Roctool technology.
Also, the different roughnesses are well felt when touched. The roughness measurement carried out using optical rugosimeter confirms the above
with repliction rate of up to 98%.

4. LAB COLOR PRINCIPLE
The Lab color space describes all perceivable colors in the three dimensions L for lightness
and a and b for the color opponents green–red and blue–yellow.
In the context of HD Plastics™, a spectrophotometer is used to carried out the LAB value :
spectro-guide 45/0 gloss (BYK). HD Plastics™ is following the DIN 5033 Standard.
The graph shows the LAB color scale. The lightness, L*, represents the darkest black at L*
= 0, and the brightest white at L* = 100. The a* and b* value represent the color channels.
a*: negative values indicate green while positive values indicate red. b*: negative values
indicate blue and positive values indicate yellow
ROUGHNESS MEASUREMENT PRINCIPLE
Optical rugosimeter is a measuring instrument used to measure a surface's profile, in order
to quantify its roughness.
In the context of HD Plastics™, two information are carried out using Alicona equipment
according to the standard ISO 4287:
- Replication rate : volume of the specific texture defined versus the one textured on the
mold surface quavity
- The surface roughness parameters : Arithmetical mean deviation (Ra) which evaluate the
roughness amplitude on a profile and Mean roughness depth (Rz) which measure the
maximal amplitude roughness average of the profile.
MEASUREMENT AREAS
1) The high gloss area framed in blue is the measurement area for the gloss, color and
specific roughness Rz* .
2) The red rectangle define the nano-replication area.
3) The green frame correspond to the multi-textured (VDI) area were the roughness is
measured.
*Rz: Maximal amplitude roughness mesured for filled materials

GLOSS PRINCIPLE
Gloss is an optical property which indicates how well a surface reflects light in a specular
direction. It is one of important parameters that are used to describe the visual appearance
of an object. The factors that affect gloss are the refractive index of the material, the angle
of incident light and the surface topography.
In the context of HD Plastics™, a glossmeter is used to carried out the gloss value with a
incident angle of 60° : spectro-guide 45/0 gloss (BYK). HD Plastics™ is following the ISO
2813 Standard.
The graph shows the gloss scale using glossmeter following 60° angle in the gloss unit.
Low Gloss corresponds to a textured surface, Semi Gloss and High Gloss to high polished
surface.

6. COMMENTS
The HD Plastics™ characterization trials shows a significant flow length and pressure drop improvment. The optimum mold temperature is
160°C according to the trials performed with this material. We obtain with high mold temperature a longest flow with an important
reduction of the pressure drop compared to conventional mold temperature.
Note : All the injection trials and the pressure measurements were carried out according to the protocol defined by Roctool (injection process, 2 heating sides,
cold sprue, mold design).
All pressure data are measured using eDart system (RJG).
