Extrusion Dies

Akron Tool & Die offers a proprietary line of strip dies, pellet dies, and blown film dies that were developed by our own engineers for a variety of extruded products such as thermo-plastics, specialty food items, and rubber products. We also offer custom-designed dies per customer specification.

Dies Designed for You

Akron Tool & Die offers custom designed dies for any extrusion process. We also offer die repair service and expert consultation to improve performance and reduce costs.

Dies Designed for You Details

Our engineers assess a customer’s process and production requirements, yield requirements, polymer rheology, and flow rate data using computer flow analysis. This thorough assessment provides us with the critical information we need to create a die that will meet all of a customer’s specifications.

We offer custom tooling options for a variety of processes including multi-channel flow dies, rotating blown film dies, pipe dies, profile dies, coating (T-slot) dies, and EA/MG series sheet/film dies. Our extrusion dies deliver the desired shape and finish regardless of process temperature or materials used.

We also have standard tooling options for a variety of processes including multi-channel flow dies, rotating blown film dies, ROI dies, and EA/MG series sheet/film dies. Our extrusion dies deliver the desired shape and finish regardless of process temperature or materials used.

Flow Control Die

The unique design of this multi-strand die provides identical shear history for each strand regardless of location across the die.

Flow Control Die Details

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.

Profile Dies

Profile dies include shapes as simple as a solid slug or as complex as co-extruded, cap-stocked, hollows, pipe, and multichannel dies.

Profile Dies Details

Our extrusion die tooling and sizing calibration are designed using the latest technology to produce optimum performance. All engineering and manufacturing is performed in-house, to produce an extrusion die that will meet a specific requirement at the highest rate and of the utmost quality. Akron dies and sizing have a wide range of material capabilities, including, but not limited to, ABS, Styrene, Polypropolene, rigid and flexible PVC, and polyethylene. Our manufacturing capabilities allow us to produce the most intricate and simple but effective designs providing our customers with value added solutions.

Sheet and Film Dies

We specialize in extrusion dies for sheet and film applications for any number of processes and applications.

Sheet and Film Dies Details

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.

Rotating Blown Film Extrusion Dies

We design and manufacture rotating blown film (RBF) dies and offer components for monolayer film production.

Rotating Blown Film Extrusion Dies Details

In addition to our tooling products, Akron Tool & Die assists our customers to solve sticky production problems. Whether manufacturing a 16” blown film assembly or consulting to solve process difficulties, our team of engineers will find a solution.

Die Tooling and Sizing Calibration Systems

Using the latest technology, our skilled employees can design dies and sizing systems to meet your specifications.

Die Tooling and Sizing Calibration Systems Details

 Engineering is performed in plant using the latest CAD, CAM and CNC software. Through our full-service machine shop and computer- controlled traveling wire EDM, we are able to produce tools and dies to the highest industrial standards. We are also able to take tooling to the next step with prototype tool development.

Quick Release Die Retainer

A highly valuable feature for any extrusion process, but especially when performing food extrusion or cold feed extrusion.

Quick Release Die Retainer Details

Akron Tool & Die applies our advanced engineering and manufacturing techniques to proprietary research and development projects. Our Quick Release Die Retainer is a result of that undertaking. It allows a die to be changed in just minutes, eliminating downtime and allowing for more material to be extruded and a variety of finishes to be achieved.

Extrusion Die Repair Service

In addition to designing and building customized extrusion dies, Akron Tool & Die also offers extrusion die repair services.

Extrusion Die Repair Service Details

In addition to designing and building customized extrusion dies, Akron Tool & Die also offers extrusion die repair services. Our proven system of die rebuilding begins even before the die is delivered to our door.

The steps in re-manufacturing your extrusion die:

  • Extrusion Die problems are discussed with the customer to better understand the scope of the rework. (leakage, dielines, gauging problems)
  • The Die assembly is digitally recorded.
  • A complete inspection of the outer die body is performed, noting the condition of the guards, electrical wiring and heaters, along with recording of the die gap.
  • A detailed recommendation is made to the customer on required repairs. (i.e. heaters, adjustment bolts, and wiring)
  • The die is then disassembled and digital photos are taken of the flow cavity.
  • A complete inspection of the internal flow surfaces is recorded, noting feed channel depths, manifold dimensions, and surface blemishes.
  • The chrome is stripped from the die.
  • The die seal areas are ground and the flow cavities polished. The lip area is polished to 1-3 Ra and 4-6 Ra in the flow cavity. The lip area is ground flat within .0001 per 3 inches of width.
  • The extrusion die is chromed .001 - .0015 on all flow surfaces and flash chromed on the outer body for corrosion protection.
  • The chrome is polished and any chrome build-up is removed.
  • The die is reassembled in "like new" condition and returned to the customer.
