Product Guide
Application Scenarios+
These ball lock pilot punches are used in injection mold tooling and downstream assembly to establish repeatable alignment between components during setup and maintenance. Their round tip geometry helps center the pilot accurately, improving locating consistency when installing or re-machining mold halves.
- Automotive and appliance injection molds: Use light-duty inch-format pilot punches to align standard locating features on build fixtures, mold frames, and insert stations where quick, repeatable positioning matters.
- Consumer electronics multi-cavity tooling: The coating-supported wear resistance helps maintain point condition through repeated tool indexing cycles, supporting stable locating over production runs and changeovers.
- Tool room and die-transfer fixtures: The hardened tool steel body provides dimensional stability for frequent setups, while the ball-lock interface improves retention and repeatability.
Choose this variant when inch-based, light-duty pilot alignment is required and when the XNT DayTiN® surface is beneficial for reducing wear at the locating tip.
Material & Process Details+
This series is offered in M2 or PS4 tool steel, with a XNT DayTiN® coating for improved surface wear performance at the pilot contact region. M2 (high-speed steel) is typically selected where wear resistance and edge retention are needed; it offers a balanced toughness-to-hardness profile for tooling components. PS4 is commonly selected as an alternative tool steel grade when engineers want a similar functional role with potentially different toughness and machining characteristics.
- Hardness / performance: Specific HRC values are not provided in the available data; final hardness depends on the supplier’s heat treatment for the selected grade.
- Typical heat treatment state: These punches are described as hardened tool steel, indicating a hardened condition appropriate for locating and alignment.
- Wear vs. toughness trade-off: Harder, wear-focused states generally reduce point wear from repeated contact, but can be less forgiving under shock load. The XNT DayTiN® coating helps shift the wear resistance advantage toward the contact surface.
Sizing & Selection Guide+
Selection starts with the shank diameter D and the pilot point length options, then is confirmed against the mold cavity/core locating features. The available shank diameter range is D = 25 ~ 100 in (as coded in the provided spec), and the point length options are provided in coded inch ranges.
- Match shank diameter: Choose the D closest to the receiving bore or guide feature diameter, using appropriate fit for alignment repeatability. Consider that small diameter errors can affect centering stability.
- Select point length (B and L): Available ranges include 200 ~ 500 / 200 ~ 600 / 200 ~ 700 / 225 ~ 700 and related B ranges such as 225 ~ 500 / 225 ~ 600 / 225 ~ 700, with some configurations fixed at 250 ~ 700. Use the range that ensures full engagement without bottoming against the cavity/core.
- P dimension: With P = 0.05 ~ 0.749 in, verify this critical dimension against the locating clearance and depth requirements so the pilot supports stable centering.
Because multiple length coding variants are offered, confirm which coded length family (L only vs. B/L combinations) corresponds to your mold fixture geometry.
