Ejector Pin Pilot Assemblies

Application

Used to locate and eject heavy duty metal stock in metal stamping dies.

Innovation

Locates and Ejects All-in-One Assembly

Our fully integrated “off the shelf” Pilot Assemblies locate and eject metal stock. They’re designed and manufactured for robust and superior long-life production performance.

Ejector Pin Style Design Features
(for heavy-duty stock)

Optimal stripping close to pilot
Multiple hardened ejectors
Heavy-duty (M2), one-piece design
Long-lasting spring
Self-contained assembly

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

Thickness labeled by red arrows of plate

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

To provide enough locating surface area, based on land length and diameter, between the pilot and the stock to effectively locate the stock.
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.

Max Recommended Stock Thickness — Ejector Pin Style

Pilot Dia.	Max. Stock Thickness	Pilot Dia.	Max. Stock Thickness
.3125”	.050”	8mm	1.27mm
.375”	.075”	10mm	1.9mm
.500”	.100”	13mm	2.5mm
.625”	.125”	16mm	3.2mm
.750”	.150”	20mm	3.8mm

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.
