Fin Dies Overview

Fin Dies Overview

Standard Draw Type Fin Dies

The standard draw-type fin die consists of draw, pierce extrude, reflare, edge trim, slit, feed, and cutoff stations. Additional enhancement (louvers, opposed louvers, or raised lances) and notching stations are also available. All of our fin stamping dies are of the quick change style. One person using a fork truck is capable of changing from one fin die to another in less than 1 hour.

Options to the fin die include the following:

  • Automatic Draw and Reflare Adjustment Mechanism (Fin Die Components): Quickly adjusts the Draw and Reflare Stations of the fin die to positions determined by the Programmable Logic Controller. The Automatic Draw and Reflare Adjustment Mechanism (Fin Press Components) must be purchased in conjunction with this option.
  • Quick Set Fin Die Slit: Quickly positions the upper slit blades from various row progressions in less than 1 minute. No screws or wrenches are required.
  • Special Tooling Material: Various upgrades to the standard fin die design are recommended when abrasive materials (e.g. Steel and Copper) are used because they greatly reduce tooling life.

This package includes the following:

  • Hardened plate under pierce station
  • Hardened air manifold
  • Hardened lower slit rails
  • Steel feed fingers
  • Steel cutoff strippers
  • Fin Die Slitter Blades: Slitter blades (slit blades, slitting blades) are available in either rippled or plain versions.
  • Fin Die Edge Trim: The edge trim mechanism is available in either Rippled or Plain versions.
  • Fin Surface: The fin surface design of the fin die is generally available in the form of Modified Sine, V-Waffle, or Plain Flat surfaces. Other surface designs are available to meet your production specifications.
  • Fin Stacker Tooling: Allows for proper collection and orientation of completed fins.
  • Fin Stacker Steady Rest Plates: Minimizes vibration of stacker rods.
