The process of extrusion has many types, and one of them is called plastic extrusion. In this process, natural plastic can be changed and utilized to create several products such as for example rods, seals, plastic tubes, adhesive tape and plastic bedding by using equipment like plastic extruders.

Some of the most popular plastic materials in plastic extrusion are nylon, polycarbonate, acetal, polyethylene, ABS or acrylonitrile butadiene acrylic and styrene.

What are the types of plastic extrusion?

This method is used when you wish to manufacture plastic films to produce shopping bags and objects similar to that. It really is generally much like a regular extrusion aside from the die. In this technique, the die used is like an upright cylinder which has a circular opening that may be no more than several centimeters in diameter to as big as at least three meters. One advantage of this method may be the quality variants it can provide.

In this technique, the components are cooled by tugging them through a series of cooling rolls. Also, they are in a position to accomplish the desired surface area structure and sheet thickness via this technique. An activity that follows this specific extrusion process is called thermoforming, when a sheet is normally exposed to heat until it becomes soft plastic to enable you to mold it into any shape. But, if you are going to use vacuum when accomplishing this, the method is called vacuum forming.

In this technique, plastic extruders are accustomed to create tubes like medical tubing and drinking straws. Additionally it is just like regular extrusion aside from the mixer extruder die. In this full case, a pin or mandrel can be used to extrude hollow areas. You should use one or several die depending on the number of lumens or holes necessary.

This technique uses one or a combination of several polymers to produce plastic compounds. You might use powder, liquid or pellets as feeds for injection molding and extrusion. Machineries are really useful if you opt to use this method. You can find those little laboratory machines or those huge extruders found in large sectors.

Those are simply four of the numerous extrusion processes known today. They have developed and improved over time. Each of them has its advantages and drawbacks over others. Each also requires different types of equipment.
