Core-Rod Solutions FAQs
What is core-rod tooling?
Core-rod tooling is specialized tablet compression tooling designed to create tablets with a centered hole or internal cavity. It uses a cam-driven rod system that passes through the punch during compression to form the opening.
What applications use core-rod tooling?
Core-rod tooling is commonly used for: Ring-shaped tablets Core-in-tablet designs Multi-channel tablets Specialty pharmaceutical tablets Industrial and confectionery tablets These applications require precise concentric hole formation and structural tablet integrity.
How does core-rod tooling work?
Core-rod tooling uses a specially modified lower turret that allows a core rod to move through the center of the punch tip during compression. This creates a consistent through-hole while maintaining tablet shape and compression balance.
What are the benefits of core-rod tooling?
Core-rod tooling helps manufacturers: Produce complex tablet geometries Maintain precise bore alignment Support consistent hole formation Improve product differentiation Handle specialized compression applications Precision alignment is critical for maintaining tablet quality during production.
Why is precision important in core-rod compression tooling?
Core-rod applications require tight tolerances to maintain concentric alignment and prevent rod deflection during compression. Precision-engineered tooling helps ensure consistent bore geometry, tablet integrity, and long-term tooling performance.
