Process-Productivity Analysis
We frequently analyze molding and extrusion applications in order to provide a solution to increase productivity. The analysis might include a plant visit or simply having our customers fill out a questionnaire. We have been involved in advanced processing techniques since 1977 from our beginnings at Dico Plastics Incorporated to many years at Spirex Corporation to our present day operations at Md Plastics Incorporated, our experience is unrivalled.
Barrel and Screw Measurements
In order to optimize the performance of your plasticating unit it is imperative that the clearance between the I.D of the barrel and the O.D. of the screw be within a limit that is acceptable in output and melt quality. When the gap between the screw and barrel increases, the screw that normally wipes the barrel clean and conveys material forward becomes less efficient, leaving material on the barrel wall which overheats, thermally degrades, discolors and decreases the output capacity. Output or recovery time may effect the cycle time in injection molding and in extrusion will effect productivity 100% of the time. Therefore it is important to monitor the gap vs. output/quality on a regular basis. Monitoring output and regularly inspecting the measurements of the screw and barrel will allow you to plan a capital budget and predict profits. We can help with this process by providing a measurement service. Simply call and schedule a measurement, most of the time we will provide this service free of charge!
