Parting Lock Bushings PLBSP PL Face

Parting lock bushings are used in injection mold tooling to keep the parting lock mechanism repeatably positioned at the parting line. In industrial automation and connector molding, they support stable engagement between the lock components and the stripper-side hardware, helping reduce misalignment that can lead to inconsistent parting behavior.

They are also well-suited for precision appliance and housings where stripper plates must maintain tight positional control over repeated cycles. The PL-face mounting arrangement provides alignment support on the parting line side, which is critical for smooth lock actuation.

For high-maintenance mold upkeep scenarios, the removable bushing structure enables easier disassembly and service without replacing the entire assembly, lowering downtime during preventive maintenance. The available sleeve diameters (D = 10, 13, 16, 20 mm) support sizing to the specific parting lock housing geometry in your mold design.

The provided specifications define sleeve diameter options (D = 10, 13, 16, 20 mm), but no steel grade, hardness (HRC), or heat-treatment state is included in the input data. As a result, material properties, wear resistance/toughness trade-offs, and any quenching, tempering, or surface treatments (e.g., nitriding) cannot be stated accurately for this exact variant.

When selecting a parting lock bushing for industrial injection molds, engineers typically match the bushing steel and heat treatment to the expected load, wear, and corrosion environment. In general, harder steels can offer improved wear resistance at the cost of reduced toughness, while tougher grades can better tolerate shock loads but may wear faster under abrasive motion.

• Material-grade selection: Confirm the exact bushing material/heat treatment from the product documentation for reliable sourcing.
• Specs to verify: steel designation, target hardness (HRC), and any coating or surface treatment.

Select the correct PLBSP resin sleeve diameter D to match the counterbore or housing geometry in your parting lock set. The available diameters are 10, 13, 16, and 20 mm; choosing the wrong diameter can cause improper locating, leading to play in the lock engagement or interference during assembly.

For the PL face mounting configuration, align the bushing so the mounting face references the parting line side. This helps maintain consistent positioning of the parting lock mechanism relative to the stripper plate.

• Step 1: Measure/confirm the required sleeve fit dimension in the mold (the corresponding bore/slot that receives the resin sleeve).
• Step 2: Choose the matching D value from 10/13/16/20 mm.
• Step 3: Verify that the assembly interface supports the intended clearance/fit (tolerance requirements should follow your mold drawing and the supplier’s fit guidance).

If you have multiple lock sizes in the same platform, keep the diameter selection consistent with each housing’s cavity/core side geometry to avoid variation in lock timing and engagement.
