Precision Round Interlocks | CNC Machined Centering Side Locks

Product Overview

The CNC Machined Round Interlock is a precision turning component designed for centring, positioning, and sliding interlock functions in injection molds. Manufactured with tight dimensional control, this interlock ensures accurate mold alignment, controlled sliding movement, and stable mold operation under repeated high-cycle production conditions.

Key Features & Technical Advantages

• Precision CNC turning for high concentricity and alignment accuracy

• Round interlock structure ensures smooth sliding and reliable positioning

• Optimized fit to minimize wear during mold opening and closing

• Stable performance under high clamping force and repeated cycles

• Suitable for complex mold structures requiring centring and interlock control

• Fully customized dimensions based on customer drawings (Built-to-Print OEM)

Applications & Industry Use

• Injection molds with sliding cores or moving inserts

• Multi-cavity molds requiring accurate centring and alignment

• Bottle cap and packaging molds with side-action mechanisms

• Medical and precision plastic injection molds

Mold Structure & Design Description

The round interlock is typically installed between mold plates or sliding components to control movement direction and maintain positional accuracy. Its cylindrical geometry allows controlled sliding while preventing lateral displacement. The interlock design improves mold stability, reduces wear on mating components, and enhances long-term mold accuracy.
