Applied in the laboratory, in R&amp;D or in the ongoing production process, they take quality management to a new level. When used as an online system to optimise process control, OCS solutions shorten reaction and product change times. They also offer excellent quality control and reliability as offline laboratory systems.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row_content_no_spaces&#8221;][vc_column width=&#8221;1\/3&#8243;][vc_hoverbox image=&#8221;548&#8243; primary_title=&#8221;Film Sample Preparation and Analysing&#8221; hover_title=&#8221;Lab Extrusion Lines&#8221; shape=&#8221;square&#8221; hover_background_color=&#8221;blue&#8221;]<\/p>\n<p>The OCS Laboratory Extrusion Lines test and measure the polymer properties in extruded film. The integration of optical, chemical, physical and rheological measuring devices enables quality checks in real time during ongoing polymer production or in the laboratory. The optional remote control function allows significant reductions in personnel deployment, as all systems worldwide can be controlled and monitored from a single location. All Laboratory Extrusion Lines have a modular architecture and therefore facilitate expansion as required. They are portable to ensure easy handling and simple maintenance.<\/p>\n<p>[\/vc_hoverbox][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_hoverbox image=&#8221;552&#8243; primary_title=&#8221;Pellet and Powder Analysis&#8221; hover_title=&#8221;Pellet and Powder Analysis&#8221; shape=&#8221;square&#8221; hover_background_color=&#8221;blue&#8221;]<\/p>\n<p>The OCS Pellet and Powder Scanners are used as laboratory systems for quality control and safety.
