Parting Locks Tapered Bolt Nylon Sleeve

This resin sleeve and tapered bolt locking set is used in mold-opening controllers to achieve repeatable parting between moving stripper plates and fixed components. It is typically installed on stripper-plate assemblies where controlled separation is required to stabilize downstream ejection and avoid misalignment.

• Automotive and industrial housings: Use the set to maintain consistent stripper plate positioning through repeated cycle starts/stops, supporting reliable ejection stroke repeatability.
• Thin-wall or closely guided resin parts: The tapered bolt promotes stable alignment during lock-up, helping reduce variations in parting clearance that can otherwise lead to scuffing or uneven ejection.
• Temperature-limited molding: The heat-resistant nylon sleeve is suited for processes at 80°C or lower, where thermal exposure must be minimized while preserving consistent lock engagement.

Choose the appropriate resin sleeve diameter (10/13/16/20 mm) to match compatible parting lock housings and maintain a secure, repeatable separation behavior.

The component is a nylon (resin) sleeve paired with a tapered bolt for locking and alignment. Nylon provides electrical insulation and dimensional stability in moderate thermal conditions, making it practical for stripper-plate parting mechanisms.

• Heat resistance: Rated for 80°C or lower, which helps limit heat-related deformation and supports consistent lock-up during cycling.
• Wear and toughness trade-off: Nylon sleeve material offers good wear behavior in guided contact, but it generally sacrifices high-temperature stiffness compared with steel alternatives.
• Manufacturing approach: The resin sleeve is typically precision molded for concentric fit and sliding function, while the bolt is machined to achieve the tapered geometry for reliable seating.

No specific steel grade, HRC hardness, or heat-treatment state is provided for the bolt in the available data.

Select the resin sleeve diameter D to ensure the tapered bolt seats correctly inside the mating parting lock housing and delivers stable lock-up. This product is offered with D = 10, 13, 16, or 20 mm, corresponding to nominal diameter options of the same values.

• Match to mold housing: Determine the required nominal diameter from the PL/PLB/PLP style mounting type used in your stripper-plate assembly, then choose the sleeve diameter that matches the housing bore and bolt guide features.
• Confirm functional fit: Because resin sleeves rely on controlled clearance for consistent separation, verify that the selected diameter aligns with your target parting alignment and locking repeatability requirements.
• Thermal compatibility check: Ensure operating temperature is 80°C or lower to preserve sleeve stiffness and locking stability during cycles.

Dimensions in the provided specification are fixed to the listed diameter options; there are no alternative lengths or adjustable sizes indicated.
