Harkness Industries has over 50 years experience in plastics manufacturing. This experience gives us a unique view of the world of urethane plastics and profile plastic extrusions.
In the profile extrusion process, plastic in pellet form is fed into the extrusion machine where it is softened by friction and heat. This softened plastic is fed through your custom die and cold water solidifies the plastic into your shape.
This process can produce either solid (like rods) or hollow forms (like tubes). This manufacturing process is ideal because of it’s low tooling costs, inexpensive process, and high range of design freedom.
What kind of parts are ideal for profile extrusion?
- Pipe and tubing
- Vinyl siding
- Window profiles
- Vertical blinds and other window components
- Automotive body side moldings and bumper strips
- Gutters and downspouts
- Refrigerator seals and appliance trim pieces
- Drinking straws
- Medical blood and IV tubing
- The “zip” of a resealable plastic bag
