I'm pretty knowledgeable on all types of Polymer and the benefits of the extrusion processes. Plastic Profile Extrusion is pretty interesting because it's the extrusion of plastic products minus sheeting and plastic poling. Quality plastic profile extrusion is acquired by the expert manufacturers in the tool and die department. 100% custom extrusion to any size or quantity that is needed. Different types of products are available from Window frames to Adhesive tape. The extrusion process begins when plastic is melted, and shaped into a continuous profile. Starting off the process, raw plastic is fed into a heated extruder cavity or cylinder.

Wanting to see this next process live, Youtube.com showed me everything I needed to know as if I was standing right in an extrusion factory. The plastic is usually in bead form as it is fed into the cavity. After the plastic is fed into the cavity, colorants and sometimes UV inhibitors are added to the plastic.

Once inside the plastic extrusion machine all the material and beads move through an opening in the extruder cavity towards a screw mechanism. The screw rotates and forces the plastic material through the cavity.

A lot of the processes are commons sense, or what one would think the processes involve. After it's through the extruder cavity it's time for the heaters. Inside the heaters it's a high 400 degrees F.
The temperature needs to be that high in order for the plastic to reach its melting point, this is pretty interesting, many plastic extrusion processes involved the use of three different heaters. This is due to overheating being a problem in the extrusion process.

So the heat is gradually reached allowing the plastic to melt without a chance of being burnt. Also the friction and pressure from the cavity also serve to product heat independent from the heaters. Sometimes they produce so much heat that the heaters are shut off.

Cooling fans are then applied for the specific type of plastic product. While the plastic is still in its molten state the next step in the Plastic Manufacturing process is for the plastic to go through a specially designed screen to finally remove any contaminants. Finally it's time for the profile giving die.

When it is put into the die it must immediately put into a water sealed bath, for the final stage in the cooling process. Cooling Rolls are used for more delicate Plastic products. I wonder how interesting it'd be to stand and witness right in front of those huge cooling rollers. Now it's time for the final step in this fast paced adrenaline rushing process!

The plastic product manufacturing process wraps up with the plastic wither being spooled, coiled, or cut to the desired length. Most polymer manufacturers follows the same process for the best result. Next time you need Window frames or exterior panels you know how it's made!
