Explaining Plastic Extrusion

What is plastic extrusion and how does it work? A question a lot of people in plastics manufacturing know about and some are curious about. In this post we will talk about what is involved in the process and how it can help make your business better and more efficient. There are plenty of reasons to consider using this manufacturing technique and we will go into some of that as well. Let us start with the machine itself.

The Plastics Extruder

The extruder is a relatively simple piece of machinery. It has a simple hopper where you will be placing the resin pellets to be used during the process. This is attached to a long hollow tube that is threaded on the inside called an agitator. This all ends at the nozzle which is surrounded by a cooling unit to help solidify your resin back into a more firm form.

What Actually Is Happening Inside The Extruder?

Once you begin the processing the plastic is dropped into the tubing from the hopper where it is moved along by the agitator using the threading inside. As it moves forward towards the end of the piping it begins to rub against itself. On the inside the channel begins getting incrementally smaller and smaller causing an increase in pressure. The pressure plus the friction will eventually lead to heating and this in turn will begin to melt the material into a semi-fluid state. At this point the material is extruded through the nozzle by the cooling unit and is formed into whatever shape you have chosen.

What Are The Benefits Of This Technique?

There are several reasons one might want to use this particular style. First, it allows for its own heat generation without the need for an outside source. It will save floor space and on costs for energy. Since you have no need for a secondary heating element the costs will be lower. It is a mostly self-contained piece of equipment that only requires someone to load it and to make sure that the nozzle does not get jammed so your work force will have less up time and can be more productive in other areas as necessary. This can ease the burden on them and on you as you press to meet the demands of your clientele. This is a great way to ensure that you factory floor will be moving at peak efficiency and allow you some leeway when it comes to your time frames for delivery.
