The process of extrusion has lots of types, and one of them is called plastic extrusion. In this process, raw plastic is used and transformed to produce various things such as rods, seals, plastic tubing, adhesive tape and plastic sheets by using tools like plastic extruders.
A few of the most commonly used plastic items in plastic extrusion are nylon, polycarbonate, acetal, polyethylene, ABS or acrylonitrile butadiene styrene and acrylic.
What are the types of plastic extrusion?
1. Blown film extrusion
This technique is used when you desire to manufacture plastic films to make shopping bags and objects similar to that. It is normally similar to an ordinary extrusion except for the die. In this technique, the die used is like an upright cylinder that has a round opening that can be as little as a couple of centimeters in diameter to as large as at least three meters. One benefit of this method is the quality variations it can offer.
2. Sheet or film extrusion
In this technique, the materials are cooled by pulling them through a series of cooling rolls. They're also able to attain the preferred surface texture and sheet thickness via this method. A process that follows this specific extrusion process is referred to as thermoforming, in which a sheet is exposed to heat until it turns into soft plastic so that you can mold it into any shape. But, if you're gonna use vacuum when doing this, the technique is generally known as vacuum forming.
3. Tubing extrusion
In this process, plastic extruders are used to create tubes such as medical tubing and drinking straws. It is also like normal extrusion except for the die. In this case, a mandrel or pin is used to extrude hollow areas. You can use one or a few die based on the number of lumens or holes necessary.
4. Compound extrusion
This process uses one or a mixture of several polymers to make plastic compounds. You may use powder, liquid or pellets as feeds for injection molding and extrusion. Machinery are very beneficial if you choose to use this method. You may get those small laboratory machines or those large extruders found in large industries.
Those are just 4 of the a lot of extrusion processes known nowadays. They've progressed and enhanced over the years. Each of them has its own advantages and disadvantages over the others. Each also needs different types of instruments.
