ZYLAB Cylindrical Split Molds for Powder Pressing
Overview
Optimize your powder compaction process with ZYLAB cylindrical split molds — precision-engineered tooling specifically designed for use with laboratory hydraulic presses. Manufactured from premium high-speed and alloy tool steels, these split die sets deliver excellent hardness, long-term durability, and clean powder release during tablet or pellet forming.

To grind the required materials into powder with the correct particle size ( from millimeters to micrometers), we recommend using our planetary ball mill and accessories or agate mortar and pestle set.
Applications
Cylindrical split molds are mainly used for pressing powder samples that are difficult to form or demold.
When used with a tablet press, they can be utilized to press various powder materials, such as potassium bromide (KBr), sodium chloride (NaCl), silicon dioxide (SiO₂), aluminum oxide (Al₂O₃), zirconium oxide (ZrO2), etc., to create circular samples, cylinders, or other shapes for scientific analysis and research.
They are widely applied in research, teaching, catalysis, testing, pharmaceuticals, chemical engineering, and the development of new materials.

Usage and Maintenance
- Before each use, clean the surface of the mold with lint-free paper to remove any anti-rust oil, as it may affect the accuracy of sample test results.
- Place the mold at the center of the tablet press, ensuring the applied pressure does not exceed the mold’s maximum pressure capacity.
- After use, promptly clean any remaining sample from the mold to prevent corrosion.
- If residual samples on the mold surface cannot be removed, avoid using chemical reagents for cleaning or soaking.
- For long-term storage, apply anti-rust oil to the mold and store it in a dry environment.
