Various Steel Block Core Pins No Tip Straight Flange

These straight, no-tip block core pins with an F = 0° straight flange position are used in precision die-casting and large mold tool assemblies where consistent core seating is critical. In automotive connector and sensor housing molds, the pin’s straight profile and flange geometry help maintain repeatable alignment during block core installation, supporting stable parting and reducing mis-seating over repeated cycles.

• Automotive die-casting housings: Straight no-tip seating supports reliable core positioning in high-cycle, tight-fit block systems.
• Medical device housing inserts: Flange-based locating geometry supports accurate assembly repeatability for fine-tolerance cavities.
• Industrial connector housings: Multiple available steels allow matching wear/corrosion needs to aluminum/zinc environments.

Because the product variant offers optional flange configuration and multiple steel options, it can be specified to the required wear resistance and corrosion resistance without changing the core alignment interface.

Block core pins are available in several mold steels: ORVAR SUPREME, DH2F, SKH51, NAK80, RIGOR, and STAVAX ESR. Hardness is offered across multiple grades, with listed ranges of 51–53 HRC, 61–64 HRC, 37–43 HRC, 53–55 HRC, 47–49 HRC, and 27–35 HRC, enabling trade-offs between wear resistance and toughness.

• High-hardness options (e.g., 61–64 HRC) favor abrasion/long-run dimensional stability.
• Mid to lower hardness options (e.g., 27–35 HRC, 37–43 HRC) can improve toughness and reduce risk of chipping under assembly loads.

Heat treatment state is not explicitly provided in the input data, so selection should be aligned with the chosen steel’s standard mold heat-treatment route (e.g., hardened and tempered for wear grades) and the required hardness window.

To select the correct block core pin, match the pin’s diameter and length to the mold’s locating interface and the core/block seating depth. The product provides variable ranges for P (outer diameter) of 1–20 mm (with options such as 2–20 mm and 5.01–20 mm) and L of 10–70 mm or 10–100 mm depending on the configuration.

• Choose P to fit the mating core pin bore or alignment hole in your mold block, considering clearance for assembly and thermal expansion.
• Choose L to reach the required seating depth without bottoming out on block features.
• Flange constraints: flange thickness H = 4–6 mm and flange thickness change HC = 2–6 mm are fixed ranges when flange is included; flange position is fixed at F = 0°.

Because tolerance values are not provided, engineers should verify target fit (clearance/interference) using the mating bore specification in the mold design and the selected steel’s expected thermal growth.
