Key Features
- Utilizes an upper punch with an integrated center rod to create a cavity for the tablet core.
- Commonly applied in bi-layer tablets, liquid-filled tablets, or delayed-release formulations.
- Demands precise alignment during compression to ensure the core is centered within the shell, preventing off-center filling or compromised tablet integrity.
Tooling Considerations
- Manufactured from high-grade tool steels such as High-Speed Steel (HSS) or stainless steel to withstand mechanical stresses and corrosion.
- The delicate core pin requires meticulous cleaning and handling to avoid damage or deformation.
- Application of specialized coatings like Chromium Nitride (CrN), Titanium Nitride (TiN), or Hard Chrome helps reduce sticking, abrasion, and tooling wear, extending service life.
Core rod tooling is indispensable for complex tablet architectures, enabling pharmaceutical manufacturers to deliver innovative dosage forms with precise drug release profiles and enhanced patient compliance.
