• Multi-Cavity Plastic Mould Assemblies

• Precision Mold Inserts and Connectors

These H13 precision turned parts are commonly used where threaded connection strength, heat resistance, and positional accuracy are essential.

Mould Structure & Design Explanation

In injection mould structures, tapered threaded CNC machined components are typically applied to:

• Lock and position mold cores, inserts, or support elements

• Reduce assembly stress and improve repeatability

• Maintain stability under repeated thermal expansion cycles

Compared to straight threads, tapered threads enhance contact surface engagement and reduce loosening during high-temperature mould operation.
