The Plastic Extrusion Process Simplified:

Plastic extrusion is a high-volume manufacturing process in which raw plastic material, usually in the form of pellets called resin, is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, custom profiles, and plastic sheeting.

ex. Rigid PVC Profile
Plastic Extrusions
ex. Custom Plastic Display Profile
Plastic Exturions
ex. Custom Plastic Dunnage
Plastic Profiles

ex. Plastic Angles

Plastic extrusion is a process that creates two-dimensional shapes (length providing the third dimension) such as tubing, edging, moldings, and similar products in short sections or continuous lengths. Extruded products can be utilized as-is, or they may be fabricated into more complex assemblies by punching, bending, forming, or other techniques. Extruded products can provide a cost-effective solution to your product fabrication and assembly needs.

For over 25 years, SeaGate Plastics has specialized in cost-effective plastic extrusions

Our product development experts will help turn your ideas into high-quality finished products.

Various appearance characteristics can be introduced into the custom profile extrusion with the addition of custom color concentrates. Co-extrusion of dissimilar materials in one profile can increase the functionality of the custom profile extrusion.
