The barrel and screw constitute the extrusion system. Like the screw, the barrel also works under high pressure, high temperature, severe wear, and certain corrosion conditions. In the extrusion process, the barrel also has the function of transferri...
People use high-speed injection molding machines to shorten the injection cycle and improve production efficiency. However, in the production process of injection molding products, the slippage of the injection molding machine screw is a big problem....
In the injection molding process, the screw of the injection molding machine is often stuck and does not rotate. Usually, if the screw protection device of the injection molding machine does not work, the operator should stop it immediately. In many ...
In the screw barrel for Injection molding machine process, the screw of the injection molding machine is often stuck and does not rotate. Usually, if the screw protection device of the injection molding machine does not work, the operator should stop...
The disassembly and maintenance of the double alloy screw nozzle of the injection molding machine has been a problem that many users have been very concerned about. Here is how to replace and install the screw correctly and effectively. After reading...
The Conical twin screw barrel is developed on the basis of the single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability, etc., it has been widely used in extruded produc...
The screw is composed of a feeding section, a compression section and a metering section. The outer surface of the screw is a cylinder with a spiral groove or a cone with a conical spiral groove. Screws are used in plastic molding equipment, such as ...
We know that conventionally speaking, the twin-screw barrel is connected by building blocks, and the connection method is flanged. The L/D (length-to-diameter ratio) of each barrel is 4:1, so the model is L/D=40:1. It is a 10-section barrel. Back to ...
When the screw rod rotates and pushes the extruded material to move forward du, the external heating of the barrel conducts heat to the material dao, plus the gradual reduction of the volume of the screw thread groove, 1653 makes the material squeeze...
The structure of the twin-screw extruder barrel is basically similar to that of the single-screw extruder screw barrel. From the appearance and structure, the twin-screw barrel is also divided into an integral barrel and a segmented barrel. Integral ...
The material of alloy screw barrel is generally 38CrMOALA or SACM645, the specific selection please see: 1, PC process characteristics are: melt viscosity to shear rate sensitivity is small, and the temperature sensitivity is large, no obvious meltin...
The attributes to consider when selecting a level include:Corrosion resistanceOxidation resistance vulcanizationStrength, ductility and ambient temperature at useAdaptability to processing technologyAdaptability to washing processStability of perform...
