Intelligent Vertical Conical Twin Screw Extrusion System vs Common Horizontal Conical Twin Screw Extrusion System
| Vertical Conical Twin Screw Extrusion System | Horizontal Conical Twin Screw Extrusion System | |
| Extrusion direction | Vertical extrusion, convenient charging, preventing the climbing pole phenomenon, and adding liquid additives and raw materials mixed with good dispersibility. | Horizontal extrusion, easy to add material to climb the pole bridge. Poor dispersion of liquid additives and raw materials. |
| Feeding method | Measured feeding and side feeding system for smooth and continuous feeding. | Difficult to realize measuring feeding, easy to jam, poor continuity |
| Data collection | Real-time data visualization of torque, pressure and material temperature acquisition | No data acquisition |
| Continuous processing | Wide range of expansion modules, switchable injection molding, wire drawing, extrusion, coating, etc. | Few options available |
This vertical extrusion micro conical twin-screw mixer has significant advantages over traditional equipment: its low material consumption can quickly complete a variety of extrusion processes such as injection molding, film, filament, pelletizing, etc., and the experimental efficiency and repeatability of the results are simultaneously improved. The system is equipped with a real-time monitoring function of screw torque, six independent temperature control module, so that the processing process is precisely controllable, while reducing the cost of research and development, to provide more efficient experimental solutions for materials science research, and to promote the industry to the direction of high-precision, high-reliability.
Miniaturization:
The size of the equipment is 580x360x780mm, which occupies a small area and can be operated and used in the lab bench and fume hood. The mixing experiment can be carried out by using 5~15g raw materials, which is especially suitable for the processing experiment of micro samples.
Specialization:
The screw is a double helix variable pitch and variable diameter screw with independent intellectual property rights, which effectively prevents highly viscous polymers from climbing; there is an internal circulation channel for blending in the material chamber with independent intellectual property rights, which can simulate the residence time of polymers in the screw.
Functionalization:
Equipped with independently designed rheology control software, it can measure the rheological properties of the mixture, with axial force measurement, and can realize single cycle blending, timed cycle blending, continuous feeding blending, constant speed blending, and constant torque blending processing experimental modes.
Rapid:
The experiment operation is simple and efficient. From melting, polymerization, and extrusion to injection molding samples, maintenance takes just ten minutes.
Simplicity:
The barrel can be opened 180 °, easy to clean and maintain the cavity and screw; screw and cavity are imported mold steel, and the minimum wear and chemical resistance treatment.
Expanded interface:
It can be used with a micro-injection molding machine to make injection molding samples. It can be equipped with film-drawing and spinning port molds to carry out simulated spinning, cast film processing, water-cooled granulation and other experiments.
