Quality surface characterization:
1) Visible improvements using Roctool technology are observed: weld line and sink marks are removed. Glass fibers and defects are removed from
the surface.
2) Significant improvement on the gloss value up to 365%. However, we measured a slight impact of the mold temperature on the color perception.
However the surface finish with Roctool is drastically improved with high level of gloss compared to conventional process.
3) The different textured areas hightlight the positive impact on the replication using Roctool technology. 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 82% : an
improvement of 278% with Roctool compared to conventional technology (CIM).
Also, the Rz value has been carried out and shows the positive impact of Roctool with an important reduction of the roughness on high gloss surface
due to the elimination of glass fibers at the surface.

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 box correspond to the multi-textured (VDI) area were the
roughness is measured.
*Rz: Maximal amplitude roughness mesured for filled materials
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.
LAB COLOR PRINCIPLE
The Lab color space describes all perceivable colors in the three dimensions L
for lightness and a and for the olor opponents green–red and lue– ello .
In the context of HD Plastics™, a spectrophotometer is used to carried out
the LAB alue : spe tro-guide / gloss BYK . HD Plasti s™ is follo ing 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
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 onte t of HD Plasti s™, a glossmeter is used to carried out the gloss
value with a incident angle of 60° : spectro-guide 45/0 gloss (BYK). HD
Plasti s™ is follo ing the ISO 8 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.

7. Flow Length improvement vs Injection Pressure in function of Mold Temperature/Mold Thickness
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).

Pressure Drop between the 2 Sensors vs Mold Thickness at
Injection Pressure = 1000 Bars
Results Evaluations
The graph above shows a flow length for the two
thicknesses at two temperature (80°C and 180°C). By
comparing these curves, a significant reduction in thickness
can be observed.
With Roctool technology, we are able to achieve an
equivalent flow length at 1 mm compare to 1.5 mm in
conventional technology.
Also, the following diagram shows the pressure drop
measured between the two sensors for the two thicknesses
at 1000 bars of injection pressure. The reduction of
pressure
drop in the cavity is important up to 112%.
GLOBAL COMMENTS & RECOMMENDATIONS
The HD Plastics™ characterization trials shows a significant flow length and pressure drop improvment. The optimum
mold temperature is 180°C regarding to the trials performed with this material. We obtain the longest flow with an
important
reduction of the pressure drop compared to the conventional mold temperature.
Also, we demonstrated that we could reduce the thickness of injected parts from 1.5 mm to 1 mm.
