HUACHENTM Screw Barrel FAQ
1. What is screw barrel?The screw barrel is an important part of the extruder. Spiral grooves are usually cut into the outer surface of cylindrical or tapered screws. The barrel structure is generally a through-core cylindrical steel with holes, a segmented structure barrel is connected by a flange.
2. What are the functions of a screw barrel?Screw and barrel work together, the barrel contains the screw, and the screw rotates in the barrel. When the screw rotates and pushes the plastic material forward in the barrel, the heat is transferred to the plastic inside the barrel by heaters outside, as the screw thread volume gradually reduces, the plastic in the threaded groove is evenly mixed and plasticized by various forces such as extrusion, turning, and shearing, and gradually melts as it moves to the front of the barrel. To ensure the extruder continuously extrudes raw materials to moulding, the screw barrel works together normally.
3. What is the difference between an extruder screw barrel and an injection screw barrel?Generally, extruders are used for continuous production of products with the same cross section, such as pipes, bars, profiles, etc., by extruding molten plastic through a fixed shape extrusion outlet under the effect of a screw, then cutting and sizing it with traction machines after water cooling. In addition, it can be used to modify plastic by granulating it. Injection molding is the process of injecting molten plastic into a mold, cooling the product and then releasing it. In terms of structure, there is a difference between the two types of machine screws. Extruder screw threads are generally bent and narrow, while injection molding screw barrels allow plastic materials to flow in the mold.
4. What is the average life expectancy of a screw barrel for extruders?It is possible to replace the screw barrel of the extruder. If you are extruding new materials of high quality, the screw barrel would last longer. A high filling extrusion or recycled material extrusion requires a very high quality screw barrel, and the screw barrel must be replaced when the output decreases after wearing out.
5. Is HUACHEN SCREW a trading company or manufacturer?China's largest screw barrel producer, HUACHEN SCREW, has been manufacturing screw barrels for a long time. Also, HUACHEN SCREW is a source supplier for many famous machinery and end product companies. With HUACHEN SCREW's own foreign trade department, customers around the world can purchase the original high quality screw barrels at the most competitive price.
6. What is the best way to order your new screw barrel?Please identify your screw barrel model and provide original assembly data, such as screw diameter, L/D ratio, barrel out diameter and screw spline dimensions, or an accurate drawing. Please indicate the end product you are producing and the filling ratio of the raw material in order to determine the appropriate screw design. You can begin ordering your new screw barrel once you obtain a satisfactory quote.
7. How to find your screw barrel size?The screw barrel model is generally represented by the outer diameter of the screw threads and the screw L/D ratio for parallel twin screw barrels and extrusion single screw barrels. A screw's L/D ratio, or screw diameter, D, is the outside diameter of its threads. A screw's effective length, L, is the length of its working part. The screw's effective length differs from its total length. The length-to-diameter ratio represents the ratio between the screw's effective length and its diameter. In contrast, the conical twin screw barrel represents the different models by the small and large thread out diameters of the screw head. For an accurate quote, it is important to know the barrel outer diameter.
8. HUACHEN SCREW's quoted price includes how many components?A complete set of screws and barrels is included in the quotation from HUACHEN SCREW. Separate orders are generally not recommended.
9. What is the processing time for screws and barrels?It takes 7 days for a Stork model to be ready for delivery. In peak season, lead time is 45 days, in off season, it is 33 days
10. How to transport your new screw barrel?The shipping method is usually LCL. Shipping methods include LCL by sea, LCL by rail, and LCL by aircraft. Screw barrels of smaller sizes can be shipped by international express. It is possible to make delivery at the factory and ship it to the location where the container will be loaded.
