Extrusion Processing

From conceptual drawings to finished products, we listen to our clients and custom make plastic extrusions to fit their needs.

Dual/Tri Durometer

Dual-Extrusion

A dual-extrusion is the combination of two different thermoplastic materials as a single profile. The materials used for dual-extrusion must have compatible physical and chemical properties in order to flow together and create homogeneous or mechanical bonds.

Tri-Extrusion

As the name implies, a tri-extrusion is a combination of three dissimilar materials that are bonded to form a single profile. Tri-extrusion is usually done with vinyl materials and reflects one of the following combinations:

• One rigid and two flexible components.
• One rigid component and a combination of semi-rigid and flexible materials.
• One rigid and two semi-rigid components.
• Flexible or semi-rigid PVC may be used as a protective capping layer. This layer prevents loss of color or glossiness during exposure to the sun and weather. The other two parts of this type of tri-extrusion perform the same functions as the materials in a dual-extrusion.

Rigid/Flexible

Materials expand and contract in length when exposed to changing temperatures. For some materials, the amount of movement can be substantial. That’s why it is essential to account for movement in the final part application, part fabrication and inspection.

Amorphous Plastics

Amorphous plastics are for structural applications only (not suitable for bearing and wear).
