Things to Consider
Stock Thickness / Pilot Diameter
Below are three main factors that should be considered when choosing a Pilot size/style for your design. We offer different sizes/styles in order to provide the best possible solution based on your part design and tool application.
Ejection Style
Mounting Configuration
OR
Style: Ejector Pins Style: Round Stripper
Style: In Pad - with Fastener(s) Style: In Window
OR
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” mis-hits / mis-feeds where the pilot is required to pierce and/or form the stock.
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.
For Thin / Soft Stock - The Round Stripper style will provide a better stripping
condition by providing more contact surface between
the stripper and the stock.
Used when mounting
directly in a pad without a window.
Retained with Fastener(s).
Used when a window is mounted
to the pad. Retained by a shoulder on the pilot assembly and a step in the window.

Clearance minimizes the forces subjected on the Pilot and tooling during a Mis-hit situation. The hole below the pilot allows the material to extrude, rather than creating a “pinch trim” situation.

Usage Guidelines:Round Stripper Style for Thin/Soft Stock
Clearance minimizes the forces subjected on the Pilot and tooling during a Mis-hit situation. The hole below the pilot allows the material to extrude, rather than creating a “pinch trim” situation. Due to thin stock, we recommend that the clearance per side is equal to the stock thickness. This allows for adequate clearance during a mis-hit while still supporting the stock during normal running conditions.
Stock Thickness to Pilot Diameter
“Receiving Hole” Clearance Requirement
The Round Stripper Style Pilot Assembly is for use with Thin / Soft
Stock only. 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.
Fully SupportedBody
Clearance for Stripper and Spring
Clearance Hole Diameter Formula:Pilot Diameter + (Stock Thickness x 2)
Testing was done to ensure each pilot diameter could handle the worst case scenario that was
still within our recommendations. This was done using high strength stock at the max
thickness with a mis-hit of a half of a hole, thus subjecting all of the forces against the pilot in
one direction.
