Application Scenarios / Industry Use

• Injection mould forming gear mechanisms

• Casting and movement systems inside mould tooling

• Packaging cap mould transmission structures

• Medical packaging mould drive components

• Precision mould assemblies requiring gear motion

Mold Structure & Design Description

Forming and casting gears are functional transmission components used to convert rotational or linear motion within injection mould systems. Machined from S45C steel, these gears are typically applied where moderate hardness, impact resistance, and stable operation are required. Gear geometry, tooth accuracy, and alignment are controlled to ensure reliable mould movement and reduced wear during continuous operation.
