Mold Structure & Design Description

In laboratory dropper molds, core pins are critical forming elements that define internal flow channels and droplet geometry. M340 core pins are typically installed in core plates or insert assemblies and must maintain precise concentricity and surface quality to ensure repeatable molding results.

Senlan Precision manufactures core pins based on:

• Customer-provided 2D/3D drawings

• Specified tolerances, surface roughness, and fit requirements

• Defined mounting structures and assembly conditions

• Compatibility with existing mold bases and insert systems
