Hydraulic press for pressing active powders

CHAMPALLE has unique know-how in designing and developing hydraulic presses and pressing particularly reactive powders. It hold extensive intellectual property whilst meeting clients’ individual specifications in terms of reliability, productivity, size, and maintainability.

These presses are for the manufacture of different types of pellets, which will then be sintered: pellets can be cylindrical or parallelepiped. Their dimensional accuracy is predetermined and their surface finish must be perfect.

CHAMPALLE’s experience in this field enables it to offer complete solutions, including design and build of:

  • up-line installations for preparing powder for pressing;
  • the full press with its Atex-certified and PC supervised control equipment;
  • down-line control stations for checking the dimensions of the pellets by laser and checking their surface finish by camera;
  • the pellet palletizing system for transferring them to sintering furnaces.

CHAMPALLE designs hydraulic presses of over 50 tons capable of producing one or more pellets per press cycle. The die-holding tool is fitted with a sealed oil pressure compensator to ensure that pressing is well distributed on every punch.

Upon request, the press is fitted with a fixed or floating matrix.

The particularity of CHAMPALLE presses lies in the fact that they are especially sturdy and accurate and are perfectly designed to meet the specific criteria and constraints to be found in nuclear environments, for example.
