To determine the minimum mold opening time required of molded IMC parts in a more quantitative way, at each molding temperature, the surface quality of molded parts was evaluated by using a Wyko NT9100 optical profilometer
(Bruker AXS Inc.).
Mean surface roughness (Ra) of the specimens were analyzed by a tactile profilometer
(Taylor Hobson Surtronic 25, Leicester, UK) initially and after polishing with a 0,25 mm cut-off value.
In this study, a stylus-type surface profilometer
(Surfcom130A, Mitutoyo) was used for the measurement of arithmetic average of surface roughness (Ra) on the resultant machined surface.
To measure the roughness of the surface, a profilometer
, Surtronic 3P, was used with a cutoff equal to 2.5 mm.
To assess the validity, a microstep (surface gold-plated, a testing sample of Lyncee tec) was measured by the setup of DDHM, and a stylus profilometer
(KLA-Tencor, P-16 +/P-6) with the force of 1 mg for comparison.
Surface roughness results were measured using a contact profilometer
. There was a significant improvement in surface smoothness from the three-screen 44 GFN silica to the four-screen 67 GFN silica.
Preparations were blotted dry and initial measurements taken with a surface profilometer
(Mitutoyo Surftest SJ-210) to determine baseline surface roughness.
Surface roughness measurement with the help of surface profilometer
revealed that samples treated with blasting with alumina (50[micro]) blasting followed by acid etching with 2% hydrofluoric acid showed the highest mean roughness value.
The latest evolution of WITec's TrueSurface advanced optical profilometer
enhances the power and user-friendliness of confocal Raman microscopes.
The thickness of the coatings and the surface roughness was measured with a stylus profilometer
Veeco Dektak 150 3D.
The surface roughness of porcelain was measured with a noncontact optical profilometer
. For each porcelain sample, two readings were taken across the sample, before porcelain surface treatment (T1) and after porcelain surface treatment (T2).
