About Guill

On the Leading Edge of Extrusion Tooling Technology

We’ve manufactured quality products for the defense and extrusion industries since 1962. From the business’ inception, we’ve applied the same quality standards in our extrusion division that are required by our government customers in our Guill Defense division. This, coupled with lean manufacturing are what give us the leading edge in extrusion tooling innovation.

Applying such quality systems in both the Guill Extrusion and Guill Defense divisions helps strengthen, support and drive end-user excellence company wide. The need for our customers to remain competitive in the market can only be supported by our continuous product innovation and superior engineering.

Applications for our extrusion tooling include medical tubing, multi-lumen and multi-layer, profile products, fiber optics, automotive hose & tube, industrial hose & tube, pipe, blow molding, blown film, food, packaging, pelletizing, rubber & silicone, wire & cable and wood composite.

Utilizing the latest 3D CAD/MCAD connected with FEA (Finite Element Analysis) and CFD (Computer Flow Simulation), our engineers were first to develop the FlexiSpiral™ deflector, the patented FeatherTouch™ die adjusting system for 100% concentricity control and the SealRight™ feature. Our engineers have also developed a QuickChange manifold for rapid change of color and/or material.

We’ve been an ISO 9001 facility since 1995. The ISO 9001:2015 guides the work processes at every level. We’re dedicated to a continuous quality improvement process.
