Product Guide
Application Scenarios+
These selectable-length mold opening prevention plates are used in injection molding tooling as a safety sealing element that helps prevent unintended mold openings during machine operation.
- Automotive and industrial connector molds: Install the plate in the safety configuration to maintain stable clamp behavior. The selectable C/L hole pitch from 15 to 130 mm and width options (B = 16, 20, 25, 38 mm) support repeatable alignment to existing mounting features.
- Medical device housings: Pair with an OPP-C, OPPH-C, or OPPS safety arrangement to improve process consistency and reduce downtime caused by safety-related interruptions.
- High-mix production lines: Use the slotted hole pitch options to fine-tune positioning when repeated setup variation exists, improving sealing reliability without changing the overall plate selection.
The ability to select hole pitch designation and layout makes this variant suited for tooling families that require consistent, machine-safe closure across different mold sizes.
Material & Process Details+
The provided specifications focus on geometry and safety configuration; no steel grade, heat-treatment state, or hardness (HRC) is specified in the input data. Therefore, material-specific claims (e.g., wear resistance, toughness trade-offs, nitriding/quenching behavior) cannot be stated reliably for this exact SKU.
For mold-safety plates, engineers typically validate fit, stiffness, and surface wear behavior based on the supplier’s drawings and incoming inspection records. If you need a material comparison (for example, pre-hardened vs. quenched & tempered steels, or nitrided surfaces), confirm the actual plate material and heat treatment from the product technical sheet.
- Current input: Selectable hole pitch designation, width (B), slotted hole pitch options, and safety coloring only.
- Next step: Request the material spec to select the correct surface protection and to confirm expected durability under repeated safety cycling.
Sizing & Selection Guide+
Dimension selection is driven by matching the plate’s mounting hole geometry to your mold safety mounting points while maintaining correct sealing alignment.
- Choose C/L (hole pitch) : Select a C/L in the range 15 to 130 mm based on the distance between your mounting holes.
- Select width B: Use B = 16, 20, 25, or 38 mm to fit available space around the safety interface without interference.
- Confirm hole geometry (D/d - S): Match the specified hole dia./slot-related parameter set (7, 9, 14, 5, 8, 10 mm) to the tooling hardware and the intended “slotted hole pitch” alignment requirement.
- Safety coloring: Pick Black, Red, or Yellow to conform to your factory’s safety tagging scheme.
If your assembly uses slotted mounting, prioritize hole pitch designation and slotted hole pitch (S) to allow for the required positioning tolerance during installation. Use engineering drawings to verify whether the mold side uses fixed locating features or adjustable mounting allowances.
