Ensuring tablet punches and dies are kept in optimum condition to produce high quality tablets is critical for your productivity and Overall Equipment Efficiency (OEE). This will also give you, your customers, auditors and regulators peace of mind by ensuring full compliance and traceability.
Unfortunately tablet compression tools have often been viewed as consumable items and maintenance can be seen as unnecessary and time consuming. This is a false assumption that can be costly. Keeping your tooling in good working condition reduces tablet press downtime and compression problems. The vast majority of punch and die problems can be conclusively traced back to poor handling and maintenance procedures.
I Holland recommends following a simple 7-Step tool care process to help our customers achieve optimum lifetime and performance from our tablet tooling.
Tooling should be thoroughly cleaned and dried to remove any oil or product residue.
Visually inspect tooling for signs of obvious damage and establish if maintenance is required.
Light surface corrosion and damage can be polished out and repaired to extend tool life.
Essential after repair and recommended at regular intervals to ensure that critical tooling dimensions remain within tolerance.
Quality polishing will result in a smooth mirror finish to minimise tabletting issues.
Lubrication is important to protect, preserve and aid the smooth operation of the tablet press.
Specially designed storage cabinets should be used to maximise security, safety and minimise potential damage.
