Runner Flow Direction Change Pins for Z Pins

This runner flow direction change pin is used inside sprue/runner tooling to hold precise alignment when a runner transitions to a new flow direction (Z-pin based runner layouts). By maintaining positional repeatability at the changeover area, it helps prevent misalignment that can lead to gate/runner mismatches and flow imbalance.

• Automotive connector and small-part molds: Suitable where multiple runner segments require consistent shutoff and alignment during part-to-part repetition. The configurable length range (ejector guide length F = 7–30 mm) supports different Z-pin runner assemblies while keeping the direction change stable.
• Consumer electronics and housings: Helps reduce flow disruption during runner redirection, which supports uniform filling for thin-wall features and fine inserts. Compatible tip shapes (I, K, L, N, T) allow matching to groove geometry in the runner change zone.
• Industrial automation housings with high cycle demands: Provides durable guidance for repeatable alignment, supporting smoother production operation and lowering the risk of downtime from cumulative runner misalignment.

The provided product metadata does not specify a steel grade, heat-treatment state, or hardness (HRC). As a result, Axiom Molds can only describe material properties at the level of what is supported by the listing: the component is offered in multiple dimensional variants (tip shapes and groove-related diameters) intended for precision alignment in runner-change tooling.

For runner components and guide pins, suppliers typically select steels optimized for wear resistance and dimensional stability, then apply heat treatment such as quenching & tempering or nitriding depending on the load and sliding conditions. However, because no specific grade (e.g., SKD61/H13, SKH51/M2) is stated here, hardness and wear–toughness trade-offs (e.g., higher hardness improving wear at the expense of toughness) cannot be confirmed for this exact variant.

To select the correct runner flow direction change pin, match its geometry to the runner groove change design and the Z-pin assembly envelope. Choose the outer diameter D first (8, 10, 13, 16 mm) so the pin fits the corresponding guide/retention feature in your mold base.

• Tip/groove compatibility: Select the tip shape (I, K, L, N, T) and the groove-related dimensions A, B, and C (A: 3 / 3–4 / 3–6 mm; B: 1–1.5 / 1–2.5 / 1–3 / 1–4 mm; C: 2 / 2–2.5 / 2–3 / 2–4 mm) to match the runner groove profile at the flow direction change.
• Length and guidance: Use the fixed ejector pin guide length F = 7–30 mm and select the L variant from 15–50, 20–60, 20–50, or 30–60 mm depending on available assembly space. For alignment sequencing, confirm LC = 20–49.9 or 20–59.9 mm against your layout.
• Inner diameter P: Ensure P = 3, 4, 5–6, or 8 mm fits the mating Z-pin/runner interface.

Tolerance and fit are not specified in the listing; confirm clearance requirements with your mold design drawings and the mating part’s tolerances.
