Typical barrel-heating capacities are based on watts/in. of barrel outside surface area, and they have little relationship to extruder output. The typical values used are 25-35 W/in., depending on how quickly the extruder manufacturer wants to be able to reach startup temperatures.

The Shaped Cast-In Heaters are typically used on square and rectangular twin screw extruder barrels in compounding and plastic resin manufacturing applications. Due to high shear rates, which are common in this process, extreme operating temperatures and high watt densities are frequently encountered. For these reasons Tempco

2/10/2013.Extruder Barrel Pressure. The pressure inside the extruder barrel during the extrusion process is high. Barrels for most extruders are designed to withstand operating pressures up to 10,000 psi or 700 bar. Normal operating pressures generally range between 1,000 and 5,000 psi. or 70 and 350 bar. Too much pressure could rupture a barrel.

Conditions and Methods of Use of Extruder Screw Barrel. 1. Heating method of extruder screw barrel. The machine heater widely uses resistance heating, and uses thermocouples to realize segmented temperature control and detection. The resistance heating uses resistance to generate heat to the barrel, and then transfer the heat to the plastic in it.
The main spare parts for twin screw extruder include gearbox, screw element, barrel, heater and other parts. Die Head Plate This is where the extruded raw material is shaped into strands through the die holes.

JINZE SCREW offers you anti-corrosion and anti-abrasive bimetallic solutions to extend service lifetime of screw and barrel. JINZE series conical twin screw barrel extruder is for your PVC products processing. It has advantages such as optimum melt homogeneity, high specific output rate and low maintenance.
The screw extruder relies on the pressure and shear force generated by the rotation of the screw to enable the materials to be fully plasticized and uniformly mixed and formed by the die. Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and rare multi-screw extruders and screwless extruders.

The main extruder is also consist of motor, gearbox, screw, barrel, heater, cooling system etc. 1.For our extruder, the extruder motor normally uses SIEMENS Beide / WN brand. But it has a standard type or separa y air fan force cooling type.
The ceramic heaters are robust in application and for long term and 7/24 application. The double insulation guarantees that only a small percentage of the heating energy is lost in plant heating and the most of energy is actually for plasticization. This is not only good for the process itself or for energy saving, it is good for our environment.
