Standard and Custom Plastic Profiles and Tubing 

We have the capabilities to fulfill your requirements FAST and SAVE you money

Simply put, plastic extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. The process can produce such items as seals, angles, channels, rods, and tubing/pipe just to name a few. Whether you are in need of a common standard profile or tube or something more complex with a custom design, our decades of experience in plastic extrusion manufacturing allow us to assist you in achieving the most efficient product possible.


Seagate also has many U-Channels, Edging, H-Channels, Connectors, Angles and Tubing in stock and ready to ship.

Plastic Extrusion Process – How it works

The process starts by feeding plastic material in the form of pellets, granules, flakes or powders from a gravity fed hopper into the barrel of the extruder. The raw plastic material enters through a feed throat prior to coming in contact with the screw. A rotating screw then forces the plastic beads forward into a heated barrel. A combination of heaters arranged along the barrel of the extruder and turning screws are used to gradually melt the material. At the front of the barrel, the molten plastic leaves the screw and is pushed through a screen pack to remove any unwanted contaminants that may be in the melt. These screens are reinforced by a thick metal breaker plate due to high pressure that is created. The screen/breaker plate assembly also create back pressure in the barrel, which is required for uniform melting as well as proper mixing of the polymer. Once the molten plastic passes through the breaker plate it is then forced into a die, which shapes the material into a shape known as a plastic profile. The die is what gives the final product its profile and must be designed so that the plastic flows evenly from a cylindrical shape, to the product’s final profile shape. Following the die, the product must now be cooled to harden. This is typically achieved by pulling the extrudate through a water bath.
