Lab Screw Extruder DW5131
Lab Screw Extruder ,also named Pelletizer or Lab Extruder which can be divided into right Angle and bevel head, depending on the direction of the flow direction and the Angle of the center line of the screw. The nose of the shell is usually fixed on the fuselage with bolt.
Lab Screw Extruder DW5131
Lab twin-screw pelletizing extrusion system can be applied to the pelletizing extrusion of various kinds of plastics, as well as possessing fundamental characteristics such as plasticizing, homogeneous melting, color proofing, filling modification, etc, suitable for polymer processing.
We provide reasonable price and high quality Lab Screw Extruder
Follows are features of Lab Screw Extruder
- Screw diameter: 20mm, 25mm, 30 mm, 35mm (optional); Screw L/D: 10 ~ 40 times (optional);
- The screws and charging barrel, made of chromium-molybdenumalloy tool steel 40CrNiMo, are processed with nitriding, hardening and tempering, chromium plating and ultra-precision grinding to meet the requirements of high stiffness and strong resistance to abrasion and corrosion.
- Based on building block principle, the twin-screw is composed of screw-conveying blocks, milling blocks, shearing blocks, remilling blocks,etc. These screw elements, composed of kneading blocks with different alternate angles and widths, can supply different shearing forces and achieve the mixing effect required in production of a variety of materials, as well as can be scheduled and combined according to different materials.
- Twin-screw elements are equipped with self-cleaning function, for example cleaning up each other when rotating at a high speed in order to reduce the waste of materials and cleaning time.
Application
Application of Lab Screw Extruder
Lab Screw Extruder can be applied to the mixing, plasticizing and extrusion of engineering plastics, modified plastics, masterbatch and other high polymers with the features of uniformly dispersed, plastics coloring and filling to modify. It can be used in laboratory tests, quality control, teaching research and small-scale production.
The efficiency of small extruder in laboratory is mainly reflected in high output, low energy consumption and low manufacturing cost. In terms of function, extruder has been not only used in polymer extrusion molding and mixing process, its use has been widened to food, feed, electrode, explosives, building materials, packaging, pulp, ceramics and other fields.
The modular production of small extruder can meet the special requirements of different users, shorten the research and development cycle of new products, and strive for greater market share. And specialized production extrusion equipment for each system module components can be arrange designated production even for global purchasing, this to ensure the quality of the whole period, reduce cost, accelerate the capital turnover is very favorable.
Lab Screw Extruder complies with many international and retailer standards.
