M2 Steel Gas Release Straight Core Pins Flat-SVC

Used in injection mold toolsets that require controlled venting, this gas-release straight core pin helps create consistent air escape paths while maintaining stable core guidance. The Flat-SVC geometry extends the flat section to the bottom, improving anti-rotation positioning during assembly and ejection.

• Automotive connector and housing molds: The quenched hardening steel construction supports repeated cycles where venting must remain predictable to prevent burn marks near fine features.
• Consumer electronics housings and snap-fit parts: The pin’s gas release section dimensions (DC/PC with defined SV cutting length) support fine control of venting for thin-wall cavity regions.
• General plastic part molds with slender cores: Suitable where stable core-pin alignment is critical; the bottom-extended flat helps keep the pin orientation consistent under ejection loads.

These features make this variant well-suited for gas-release core applications requiring both vent control and reliable mechanical stability.

This core pin uses quenched hardening steels in two available grades: SKH51 and SKD61. SKH51 is a high-speed steel commonly aligned with AISI M2-equivalent performance, prioritizing wear resistance for sliding and repeated contact. SKD61 is a hot-work tool steel commonly aligned with AISI H13-equivalent, balancing toughness for longer service in thermally stressed mold environments.

• Heat treatment: Quenched hardening state is specified for stable hardness and dimensional consistency across cycles.
• Hardness & performance trade-off: High wear resistance is emphasized for repeated cycles; SKH51 generally favors wear, while SKD61 typically offers improved toughness and thermal fatigue resistance.
• Steel selection: Choose SKH51 where abrasion and wear at the gas-release interface dominate; choose SKD61 when overall toughness under molding temperatures is the priority.

Exact hardness (HRC) is not provided in the input data, so verification against your incoming lot/test report is recommended for critical fits.

Select the core pin size by matching its shaft and venting features to the mold core geometry and vent requirements. The D/P (shaft diameter) is available in 0.5–13 mm with corresponding No. nominal diameter 0.6–13 mm. Choose L (overall length) from 15–100 mm or 15–120 mm depending on the configured range for your part.

• Core guidance fit: Use the specified L dimension tolerance +0.01/0 when calculating how much engagement the pin must provide at the bottom. Maintain clearance in the core bore to account for normal assembly stack-up and to avoid interference.
• Gas-release vent control: Match DC (0.42–12.92 mm) and PC (0.42–9.92 mm) to the required gas-release section, and set SV (gas-release facet cutting length) in 2–50 mm or 2–60 mm.
• Geometry options: With DC = D, DCX is applied; with PC = P, PCX is applied. The flat extension is fixed as SVC (extend Flat-SV to the bottom).

For slender core designs, verify that N (tip diameter length: 0.3–10 mm or 0.5–15 mm) supports the intended contact/venting profile without over-penetration.
