Roughness parameters
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 135%. However, we measured an impact of the mold temperature on the color perception
and Roctool technology allows a darker color with a perfect surface finish compared to conventional process.
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 81% : an improvement of 37% 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.

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
di e sio s L for light ess a d a a d for the olor oppo e ts gree –red
a d 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
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
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.
I the o te 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 i g the ISO 8 Sta dard.
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
Results Evaluations
The graph above shows a flow length for the two thicknesses
at two temperature (100°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 superior
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 175%.
GLOBAL COMMENTS & RECOMMENDATIONS
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 part from 1.5 mm to 1 mm.
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).
