The extruding is merely part of a distinct two stage extruder in the production process. It is essential that it is specified correctly to offer the final product from the material of choice on the required production rate. What feeds the material and what follows the extruder for building, calibration, dimensional control and handling belonging to the final product is involving equal importance.

The specifying process starts with all the final product. Once this really is determined, the complete line might be designed. The physical weight per meter with the product will, to a clear extent, determine the size on the extruder required but it isn't as simple as nevertheless we want to generate at, say, 500kgs a hour. An extruder can be specified to begin this, but it may not be possible to create, calibrate and cool the ultimate product at this price, so the extruder cannot be specified in isolation to the remaining process.

The raw material to get processed will influence the planning of the extruder, as an example, how the screw airfare and compression ratio was created and how long will be the barrel. This is expressed as a ratio of the length to diameter of the processing screw. The compression ratio determines just how much shear heating and work is placed in the material to make a homogenous melt. Certain materials need more time screws and barrels to raise the residence time within the extruder to give extended for heating and plasticising as well as to increase the production charge. Different materials need increased compression and shear costs to enable them that they are processed consistently. This is usually a time/temperature relationship within the actual screw and barrel on the extruder. Other materials need reduced screws and barrels plus lower compression rates to cut back the possibility of thermal degradation during processing. Probably the most common type of extruder may be a single screw machine although some thermoplastics process greater on twin screw machines that could have either parallel or maybe conical screws.

Some two stage extruder materials process better using a machine with a vacuum vent situated about the barrel to remove volatiles and also small amounts of moisture from the material. Thermoplastic materials process at different temperature requirements, from as low as 100°C as much as 400°C+ for some anthropological thermoplastics. This temperature determines the species of heaters required, particularly with the tooling to be fitted towards the extruder. Higher temperature requirements will require more robust and higher end heaters.
