PL & SSI Standard Square Interlocks - Injection Mold Side Lock

Product Overview

The PL / SSI standard square interlock side lock is a precision locating block designed for accurate positioning and alignment of plastic injection molds.
Manufactured according to PL / SSI standards or strictly to customer drawings, this mold positioning component ensures repeatable mold closing accuracy, improved lateral stability, and reliable performance in multi-cavity, high-cycle injection molding applications for packaging and medical products.

Key Features & Technical Advantages

• Manufactured to PL / SSI standard or built-to-print specifications

• Square interlock side lock design for precise mold positioning

• Improves lateral alignment and reduces mold shifting

• Enhances cavity-to-cavity consistency in multi-cavity molds

• Suitable for high-cycle and continuous injection molding

• Compatible with automated molding and high-output production lines

Applications & Industries

This square interlock locating block is widely used in injection molds for:

• Bottle caps and closure molds

• Packaging containers and functional plastic components

• Medical disposable and syringe-related molds

• Injection molds requiring accurate side locking and positioning

Typical customers include packaging manufacturers, cap and closure producers, medical consumable factories, and OEM injection mold makers.

Mold Structure & Design Description

The square interlock side lock is installed on the side of the mold base to control lateral movement during mold closing and injection.
Its interlocking structure ensures precise alignment between mold halves, helping prevent offset, reduce flash, and improve overall mold stability.
Design considerations include interlock clearance, wear resistance, load distribution, and compatibility with multi-cavity mold structures.
