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

Posi-Strip ball lock punch builds are used to keep punch position stable and support consistent ejection during repeated forming cycles. This Heavy Duty/Regular, Metric variant is suited for automotive connector and terminal molds, where progressive tooling requires uniform actuation and controlled stripper force to prevent punch wobble and inconsistent strip-out.

It also fits appliance and consumer electronics progressive tools that run high cadence and benefit from a structured stripper solution. By selecting the appropriate hole shape (E, H, J, K, L, N, O, R, V, X, Y, Z) and the punch point dimensions, you can tune engagement to the part geometry for reliable ejection.

For tool-room and pilot production, the regular bronze length types (71–90 mm range) and option to choose Heavy/Light/Medium/Extra Light stripper constructions help match force profiles to material thickness and forming load, supporting stable punch actuation without over-stressing the tool.

The provided data specifies this system as a DAYTON Posi-Strip setup for ball lock punches, with selectable bronze length types and interchangeable stripper constructions. However, no specific steel grade, heat-treatment condition, or measured hardness (HRC) is listed in the supplied parameters.

• Material/heat treatment: Not specified in the provided dataset, so hardness and thermal treatment cannot be stated accurately.
• Manufacturing process: The system is configured by selecting hole shape and punch point dimensions to match the punch/stripper build geometry; bronze length types are offered in a 71–90 mm range, indicating length-specific components for alignment.
• Trade-offs: The dataset distinguishes Heavy (SHD), Medium (SMD), Light (SLD), and Extra Light (SSD) stripper constructions, implying force-profile tuning—heavier constructions generally support higher forming/ejection loads while requiring careful setup to avoid excessive stripper force.

If you share the drawing or corresponding material spec for this series, the steel grade, target HRC, and heat-treatment details can be incorporated precisely.

Select this Posi-Strip system by matching three geometry groups: applicable punch diameter (D), bronze/punch length type, and punch point dimensions.

• Punch diameter (D): choose a build for the specified 10–40 mm punch diameter range.
• Length selection: for Regular [R], 71–90 mm bronze length type & punch length; for 3 mm Longer [L], the same 71–90 mm range is listed; Custom contour [C] also indicates 71–90 mm.
• Punch point dimensions: select P and W from 1.4–14 mm (variable), and choose R from 0.2–7.01 mm (variable). These dimensions should correspond to the punch point geometry required for stable ball lock engagement and controlled strip-out.

Confirm whether your cavity/core design uses these dimensions as fixed interfaces (geometry matching) or as toleranced fits. If your tooling drawings specify clearances, align your chosen P/W/R to those tolerances to maintain consistent actuation under load.
