Screw Size – The Screw is the heart of the extruder. It is measured in outside diameter most extruders are between .75”-10”. The most popular sizes are 1.5”, 2.5”, 3.5” 4.5 and 6”. The effective length of the extruders typically 24-36 L/D although can be shorter or longer for specialized applications. The L/D of a single screw extruder is the ratio of the length over the diameter.
Motor and Gearbox – Extruders are variable speed with either an AC motor or DC motor. DC motors have been the longstanding standard for years, however AC motors are becoming more and more popular with plastic processing. These motors can be direct driven or belt driven to gear reducers. It is important to be aware of the gearbox reduction on the single screw extruders to maintain proper screw output speeds for your material.
Barrel Cooling – Extruders will can be equipped with Air cooling or water cooling. Air cooling which is done with fans in in general less difficult to use. Water cooling is a more effective then air cooling, however tends to require more maintenance and in general more difficult to maintain.
Centerline Height – The height of the center of the screw to the floor. Typical height is 42.5”. Higher could be called Highboy Extruder, lower would be called Low Boy Extruder
Screw Design – There are many different variations of extruder screws. Conventional single stage screws have a constant pitch. Two stage screws are used for venting. Screws also can have various forms of mixing for specific applications.

Polymer dosing feeder is a device that is used in the plastics manufacturing process. Its main function is to feed the raw material evenly into the extruder in parts of the desired volume.
Screw conveyor with electric motor in very good condition. Screw conveyors are used to safely transport a range of bulk materials from station to station, such as sawdust, bark residues, pellets or other wood waste. Screw conveyors also serve as a material flow regulator, for example, to feed material to subsequent sections of the line, such as hammer mills, presses and other equipment.
Screw conveyors are used to transport bulk materials - sawdust and wood chips, bark, pellets and other green waste. Screw conveyors also serve to buffer and meter the material flow, for example when feeding downstream machines such as hammer mills, presses, etc.

Using plastic extrusion, raw plastic is melted and formed into continuous profiles. Items made by extrusion include pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheets, and thermoplastic coatings. Using a plastic extruder is a high volume process, where a lot of product is created quickly.

Extruders are typically used to turn solid plastic into a uniform melt through the heating, pressure and shear. The melt includes mixing a master-batch and other additives such as resin, and then smashing in the production process. The finished melt must be homogeneous in concentration and temperature. The pressure must be high enough for viscous polymer extrusion.
Extruder completes all of the above process through the barrel with a spiral track and a screw. Plastic pellets are fed through a hopper at one end of the barrel into the barrel, and then transmitted to the other end of the barrel by a screw. The thread depth of screw starts to decrease with the increase distance of the hopper to ensure sufficient pressure. External heating and the internal heat generated by friction in the plastic and the screw make plastic soften and melt. Different polymers and applications have various design requirements of the extruder.
The extrusion machine is normally composed by at least three segments. The first part is feeding zone near the hopper. This part can push the material into the extruder at a relatively steady rate, which will maintain relatively low temperature to avoid clogging of the feeding channel. The second part is divided into the compression zone which forms a melt and increases the pressure. The transition can be sudden or gradually (gentle) from the feed zone to the compression section. The last part is the metering zone close to the outlet of the extruder. The main function is to maintain uniform material from the outflow of the extruder. And the material should have a sufficient residence time to ensure the uniformity of the composition and temperature.
The drive mechanism controls the rotational speed of the screw which determines the output of the extruder. The required power is determined by the viscosity of the polymer (flow resistance) which depends on the temperature and the flow rate.

How Extrusion Works?Extrusion process aims to transform plastic / polymeric materials in order to produce high quality products. Twin screw extruders consist of two screws mounted on splined shafts in a closed barrel. Those screws are co-rotating which allows different types of plastic to be mixed well together. Twin screw extruders have a remarkable mixing capability which adds significant value to the production unit.
Twin Screw ExtrudersTwin screw extruders belong to Plastic / Rubber machine category on Exapro and are used for production of plastic pipes, tubes or sheets of plastic. Extrusion is actually the first stage of producing a sheet of plastic t
