DAYTON Posi-Strip Systems for Ball Lock Punches Heavy Duty Regular Inch

DAYTON Posi-Strip systems are used in injection molding and press-side tooling where ball-lock punches must feed and retract with repeatable strip retention. In automotive and electrical connector molds, controlled strip hold helps maintain alignment through frequent cycling, reducing misfeeds when running common hole geometry patterns.

For consumer product housings and snap-fit components, heavy duty regular-inch strip control supports stable punch operation across the standard E/H/J/K/L/N/O/R/V/X/Y/Z hole shape set, which simplifies setup when switching between part families.

• Medical device housings: consistent retention supports reliable ball-lock punch positioning during high-mix production runs where changeovers are frequent.
• Why this variant fits: the heavy duty regular inch configuration is designed for stable strip control, and the bronze length coding aligned to 300–350 inch punch lengths supports compatibility with defined stripper construction grades (SHD/SLD/SMD/SSD).

This product content does not specify the steel grade or heat treatment state for the ball-lock punch retention components. As a result, only the configuration-level engineering parameters can be stated from the provided data.

• Material/heat treatment: not provided (no AISI/EN steel designation, no quench & temper, nitriding, or target hardness values in the input).
• Manufacturing process: not provided (no machining/finishing steps or coating details specified).

When selecting bronze length type and corresponding stripper construction (SHD/SLD/SMD/SSD), engineers should ensure the mating punch/stripper materials match the required wear and toughness balance for the press duty cycle. If you share the compatible punch/stripper part numbers, we can map the correct steel specification and typical hardness range to your application.

To select the correct Posi-Strip system dimensions, match the hole shape and punch point geometry to your ball-lock punch layout, then confirm the bronze length type and punch length code range.

• Hole shape: choose from E, H, J, K, L, N, O, R, V, X, Y, or Z to align with the intended punch diameter and cavity/core features.
• Punch diameter (D): applicable punch dia. range is 37–125 in; confirm your ball-lock punch is within this band.
• Punch length coding: the Regular [R] bronze length type supports 300–350 inch. For other fixed options, .118 in Longer [L] and Custom contour [C] also list 300–350 inch punch lengths.
• Punch point dimensions: W is 0.05–0.5 in; R is 0.007–0.251 in; P is 0.05–0.5 in. Select the system variant that matches all three point dimensions to prevent retention interference.

Use the specified stripper construction grades (SHD/SLD/SMD/SSD) to ensure proper fit with your press-side stripper design and maintain consistent strip hold during cycling.
