DIE TECHNOLOGIES

Akron Tool & Die has the experience and technology to design and manufacture extrusion dies for any application pelletizing, sheet, film, profile, for many industries such as food, plastics, mastics, and ceramic/catalyst. We tailor to your specific needs by thorough review of requirements as well as viscosity and rheology data using computer flow analysis. The result is a solution that meets or exceeds your expectations.

Flow Control Die

The unique design of this multi-strand die provides identical shear history for each strand regardless of location across the die. Distribution is made by directing, not restricting flow. Because shear history and residence time are identical across the die, flow rate and swell are identical for each strand. This design is of particular value for shear sensitive or low viscosity materials. The technology has been applied to strand/strip dies and can also be used in rounds, pipe/tubing, sheet, film, and striping or co-extrusion dies.

Forming

Forming dies include profiles as simple as a solid slug or as complex as a multi-cell monolith and are designed with the same goal in mind optimum performance. What this means is every die is designed to produce an extrusion that meets specific requirements at the highest rate, and of the utmost quality. Our manufacturing capabilities allow us to produce the most intricate and simple but effective designs providing our customers with value added solutions.

Sheet & Film

Dies for sheet and film applications are a specialty. An internal “ coat hanger” cross section is generated from your viscosity curves and optimized for demanding output requirements and elimination of hot spots. Exclusive choker bar, thickness and width designs allow for easy adjustment on the fly. Rotating blown film dies feature a streamlined “ spider” design to keep residence time to a minimum while maintaining superb output rates. Computer flow analysis is available as a virtual test of performance.

Custom

Designing custom dies and accessories is our specialty. Our Quick Release Die retainer allows a die to be changed in just minutes. We offer engineering services in development of dies as well as remanufacturing and modification of existing components. Our laboratory is available to assist in the design of pelletizing and forming dies for various materials, and also to demonstrate their usage and effectiveness.
