A vital factor to determine the life of punch and die tooling is its clearance and maintenance. An appropriate and rational clearance and maintenance is conducive to boost tooling service life, increase tablet production and reduce unnecessary cost. Maintaining punch tooling consistently and correctly would lead to a high efficiency production. Save time and money simultaneously.
Maintenance Before Occupying
Actually, the punch press tooling should be well kept through a whole life from the very first beginning. When it is still stored in factory before flowing into the market being occupied by users, punch and die tooling should be carefully handled with rust protection and corrosion prevention.
Before packaging the punch tooling should be boiled in oil, in order to eliminate internal stress during friction, evaporate water sticking to the tooling surface and remove all dirt. Oil temperature should be well controlled. Over-high oil temperature will possibly reduce tooling rigidity so as to influence abrasiveresistance. No more than 120°
Let the punch press tooling cool to normal temperature, and surface water totally be evaporated. In order to ensure anti-rust function, it should be packaged into plastic bag or plastic box.
After handling by qualified anti-preventative oil, rust-proof life will be more than two years.
