Using Standard Lifters’ Pilots, we rarely encounter parts wanting to stick and hang up on Pilots that are in the upper pads of the die. Surrounding your Pilots with built-in ejection was quite genius.

Shop Foreman, Tooling Supplier

We require Standard Lifters’ Pilots in all our dies built all over the world. They provide superior performance and commonality across all tooling and designs.

Benefits

Superior performance maximizes uptime

  • Designed to last the life of your die using a long-life spring and ejection close to the pilot.

Global design commonality

  • Nominal sizes in both English and metric allow for one pilot style in all your global tooling.

Savings in design

  • All-in-one assembly speeds up design process and drops in your die fast.

Choose a proper Pilot Diameter based on the Stock Thickness

Stock Thickness in relationship to the Pilot Diameter is important for 2 main reasons.

  1. To provide enough locating surface area, based on land length and diameter, between the pilot and the stock to effectively locate the stock.
  2. To provide a robust assembly that reduces the potential of the Pilot assembly being damaged during common miss-hits/misfeeds where the pilot is required to pierce and/or form the stock.

Usage Guidelines & Recommendations

Choose the Best Ejection Style based on the Application

Style: Ejector Pins

The Ejector Pin style should be the preferred option whenever possible. It is more robust because the Pilot body is fully supported in the Pad/Window.

Style: Round Stripper

The Round Stripper Style Pilot Assembly is for use with Thin / Soft Stock only. The Round Stripper style will provide a better stripping condition by providing more contact surface between the stripper and the stock.

Fully Supported Body

Clearance for Stripper and Spring

Due to its Body not being supported adjacent to the Pilot “Tip”, it is less robust than the fully supported Ejector Pin Style Pilot Assembly.

A properly sized receiving hole is important

Clearance minimizes the forces subjected on the Pilot and tooling during a miss-hit situation. The hole below the pilot allows the material to extrude, rather than creating a “pinch trim” situation. See Receiving Hole Guidelines for detailed information on proper sizing.

Style: Ejector Pins

Style: Round Stripper
