Pulse Air™ Ejection Systems
Midway’s Pulse Air™ system offers an improvement over standard air eject tools. This system utilizes a special air manifold to control and direct the burst of air to each cavity as the tool rotates. This means you achieve the most effective slug removal while reducing the amount of air pressure required. Pulse Air™ dies require no press modification.
Advantages of the Pulse Air™ system:
Pin Point™ Picker Pin Matched Set Tooling
The Pin Point™ System uses a matched die and anvil configuration. This scrap removal system has been run at press speeds over 800 feet per minute with 100% scrap removal. Matched set tooling uses a "pin" to stab the scrap and pull it down through a removal comb. Some minor modification is required to the support/drive rolls for pin clearance, and the addition of the comb for stripping the pins. All modifications can be performed by Midway and are adapted for each specific application.

Spring Plunger Ejection
Screw-in spring plungers offer positive slug removal from die cavities when cutting stiffer materials. The spring-loaded plunger "pushes" out the scrap, freeing it from the die to be collected with a vacuum collection system. The plunger extends beyond the blade of the die, but retracts as the die rotates in the press. This method is highly effective for ejecting stiff materials such as metal, thick tag, rigid vinyl, and polycarbonate. Screw-in design allows for easy replacement on-site.
Advantages of Spring Plunger Ejection:
Vacuum Tooling
Vacuum dies offer an effective means for removing small die cut waste from the web. A vacuum die uses suction to pull waste through the center of the die, and out the end of the journal using a vacuum assist block. Removable inserts are used to provide increased clearance for the waste slugs that must pass into the die’s core, reducing the chance of buildup that could cause blockage of the air passage.
Vacuum dies are most effective on:
Rubber Insert Ejection
Rubber insert ejection offers a low cost method for preventing slug buildup in tooling, avoiding blade damage caused by clogged cavities. Rubber ejectors can be easily replaced by the press operator on-site. This method is used when lower press speeds and cost are dictated by the job. Rubber ejectors are also used in small cavities where air ejection is not feasible.
