HUACHENTM Screw Barrel FAQ
1. What is screw barrel?
Screw barrel are the important parts of the extruder. The screw is usually cylindrical or tapered steel with spiral grooves cut into its outer surface. The barrel structure is simple, generally through-core cylindrical steel with holes, the segmented structure barrel is connected by the flange.
2. How does screw barrel work?
Screw and barrel work together, the barrel contains the screw, the screw rotates in the barrel. When the screw rotates and pushes the plastic material to move forward in the barrel, the heat is transferred to the plastic inside the barrel by heaters outside the barrel, when screw thread volume gradual reduces, the plastic in the threaded groove is evenly mixed and plasticized by the action of various forces such as extrusion, turning and shearing, and gradually melts into a viscous flow state as it moves to the front of the barrel, completing the plasticization of the plastic. Screw barrels work together normally to ensure the extruder continuously extrudes raw materials to molding.
3. What is the difference between extruder screw barrel and injection screw barrel?
The extruder is to extrude molten plastic through a fixed shape extrusion outlet under the effect of the screw, and cut it after water cooling and shaping under the effect of traction machine, which is mainly used for continuous production of products with the same cross section, such as pipe, bar, profile, etc. It can also be used for plastic modification granulation. An injection molding machine is to injects molten plastic into the mold, after cooling is the product, the process is known as the injection molding process. The structure of the two types of machine screws is different. The extruder screw thread is generally bent and narrow, while an injection molding screw barrel is required for plastic materials to flow in the mold.
4. How is the uselife of a screw barrel for extruders in general?
The screw barrel of the extruder is replaceable. Screw barrel would last longer for high quality new material extruding. The high filling extrusion or recycled material extrusion requires a very high quality screw barrel, and the screw barrel needs to be replaced when the output decreases after wearing out by high filling raw materials.
5. Is HUACHEN SCREW a trading company or manufacture?
HUACHEN SCREW is a long history screw barrel manufacturer in Jintang Island----the biggest screw barrel produce base in China. HUACHEN SCREW is also the source supplier for many famous machinery companies and end product brands. HUACHEN SCREW has its own foreign trade department, so worldwide customers can purchase the original high quality screw barrel at the most suitable price directly.
6. How to order your new screw barrel?
First, 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. Then, please advise the end plastic product you are producing and the filling ratio of the raw material to determine the appropriate screw design. After obtaining a satisfactory quote, you can begin ordering your new screw barrel.
7. How to find your screw barrel size?
Parallel twin screw barrel and extrusion single screw barrel are generally represented by the outer diameter of the screw threads and the screw L/D ratio to represent the screw barrel model. The screw L/D ratio, screw diameter, D, refers to the outside diameter of the screw threads. The effective length of the screw, L, refers to the length of the working part of the screw. The effective length is different from the total length of the screw. The length-to-diameter ratio is the ratio of the effective length of the screw to the diameter. But the conical twin screw barrel uses the screw's small head thread out diameter and the large head thread out diameter to represent the different models. And the barrel outer diameter is one of the elements for an accurate quote.
8. How many components are included in the HUACHEN SCREW's quoted price?
The quotation from HUACHEN SCREW includes a complete set of screw and barrel. It is generally not recommended to order separately.
9. How long does it take to process screw and barrel?
The stork model can be ready for delivery in 7 days. Peak season lead time: 45 days, off season lead time: 33days
10. How to transport your new screw barrel?
It is usually LCL transportation. The shipping method supports LCL by sea, LCL by railway, and by aircraft. Smaller sizes screw barrel can be shipped by international express. Delivery can also be made at the domestic factory and shipped to the container loading location.
