The other day I ran across a familiar word as I was browsing through the never ending abyss that is Google. The word plastic extrusion caught my eye and I was tired of not knowing what this meant so I decided that day was the day my vocabulary will get a tiny bit larger. I asked around at my job if anyone knew what this meant and I got mixed results. Almost everyone said no and when someone did recognize the word they told me the wrong definition or didn't really understand what it meant. So my goal; clear up the clouded minds on the ins and outs of plastic molding. But goals such as these aren't achieved overnight; therefore I dedicated 5 days researching and cramming a lot of knowledge of this process into my head. Fascinated with the results, I read this and the next investment coming out of my pocket was towards plastic extrusion.

Information on the internet referring to plastic products is limited but growing for the most part. Having found most of my information through word of mouth and some books I rummaged through from the local bookstore, I felt lucky to share this.

I came up with a plethora of more information and who would have thought that plastic extrusion produces items such as injection molded parts, and adhesive tape. Wire insulation and window framing are also big products made from plastic extrusion.

When the plastic moves through the cavity it reaches a screw mechanism where the plastic is forced out. Inside of the cavity it is a high 400 degrees to keep the plastic at its current state. Overheating is a problem sometimes when extruding plastic so plastic companies have figured a way to defeat overheating.

The additives are actually ultraviolet inhibitors, and the processes next step is to move towards an opening in the extruder cavity. It resembles a screw mechanism, as the screw rotates it forces the plastic material through the cavity. Exciting as it is there's more to this beneficial process!

Inside the Extruder cavity it is a whopping 400 degrees and needs to be kept at this temperature to keep the plastic in its liquid state. This is something interesting; while overheating is somewhat of a problem in the extrusion business they found a way to burn proof their plastic.

Injection Molding is a process where overheating is abundant and must be avoided at all costs. The plastic companies invest in three heaters to allow the plastic to gradually reach its melting point so it will not burn. Sounds pretty genius to me and for plastic makers?

Next in the process comes the exciting cooling process. Cooling fans and sealed water baths are most common forms of cooling. But some Plastic products are too delicate for those forms of cooling so especially designed cooling rolls are put in place.

You nearly understand the long grueling process that's reaquired of a plastic manufacturer. Small businesses can benefit from these tips. Quality plastic manufacturing is an ever-growing and smart 'green' way to invest in certain products! Trusty injection molded products are just the beginning the list for extrusion products and need for them is at an all time high!
