Extrusion Press Container and Liner Change

The container is the heart of the extrusion press. Thousands of billets pass through the container and the liner during the term of their usage. The performance of the container and its liner depends on continuous maintenance and liner insertion processes at correct tolerances.

The long-term operation of the liner and the container with a good performance are very important in terms of efficiency and product quality. All diagnostic results, operating performances and measurement are precisely recorded at our production facilities. The records, kept separately for each container, include the maintenance dates, maintenance notes, liner change and records of the repair actions records.

There are many factors influencing the lifetime of the container and its liner:

  • Heating and Cooling cycle
  • Excessive heating: High temperatures influence the features of steel and excessive temperatures can result in serious damages.
  • Wear of the liner during the extrusion of each billet
  • High pressure: The extrusion pressure causes damages from the liner towards the container.

These factures will lead to premature container cracks, untimely production stops and consequently high production costs.
