Desktop Small Precision Extrusion Casting Machine

MESI-25/28
Product Introduction
The desktop small precision extrusion casting machine integrates a precision single screw extruder, a set of casting die head, and a set of precision casting auxiliary machine into one experimental equipment, which can realize all functions of screw plasticizing extrusion, casting, pulling, trimming, winding, and edge collection of a casting line. It is easy to use and operate, which can greatly improve the experimental efficiency and shorten the product development cycle. It is an ideal experimental equipment for polymer material casting molding.
*The screw is driven by a servo motor, with stepless and precise speed regulation, stable plasticization and good consistency
*Digitally designed casting die head, smooth flow channel without dead corners and material stagnation, and uniform material discharge
*Each power roller is independently driven by a servo motor, with precise speed control and good synchronization performance
*The height of the casting roller can be raised and lowered to meet the process requirements of casting molding of materials with different melt strengths
*Hard chrome-plated mirror roller, high surface finish and no rust
*Based on PLC control system and touch screen operation interface, the equipment runs stably and the human-computer interaction is friendly
*Important experimental data is measured and displayed in real time with graphics and text, which is convenient for observation
*Humanized structural design, more convenient operation
*Optional online defect visual inspection system
*Optional constant tension and follow-up roller winding device to improve the film winding quality
*Optional air knife or electrostatic adsorber to improve the adsorption effect between the melt and the roller surface
Application range
*Polymer material casting molding experiment
*Casting production process research and parameter optimization
*New material casting molding performance test
*Masterbatch dispersion performance test evaluation
