Producing a high-quality bimetallic screw barrel requires much more than standard machining — it demands precision metallurgy, material science, and years of engineering experience. The performance of an injection molding or extrusion system depends heavily on this critical component, which must endure extreme pressure, temperature, and wear while maintaining tight dimensional tolerances.

In this article, we share an in-depth look at how bimetallic technology works, why it matters, and how TSI’s expertise is helping shape the future of plastic processing.
