V-PROCESS sand casting V-PROCESS sand casting

SPEED, FLEXIBILITY & ECO-RESPONSIBILITY

THE V-PROCESS OFFERS A UNIQUE SOLUTION FOR CASTING PROJECTS, FROM PROTOTYPE TO SERIES PRODUCTION.

The V-Process quickly produces castings of any size and shape. It is a cross process, which combines the best advantages of all other standard casting processes.

The mould is designed with the utmost care and a careful analysis of the parts is carried out for each project, so that any anomalies are eliminated from the outset. A study of the feeding and filling system of the parts to be produced is essential; thanks to computer simulations, we can guarantee the high quality of the products that can be obtained in the process. The mould is manufactured in full compliance with the specifications and recommendations of the design office. The design office closely monitors the manufacturing process and carries out numerous tests in order to obtain an optimal mould.

Vprocess - Hadoux


Vprocess - Hadoux

A plastic film is heated for a few seconds

Vprocess - Hadoux

A plastic film is applied to the master model and a vacuum is created in the film, which follows the contours of the model

Vprocess - Hadoux

A frame is placed on top and filled with dry sand without binder; i.e., without resin.


Vprocess - Hadoux

The sand is vibrated and compacted, another film is applied to the frame and a vacuum is created. The sand then becomes compact due to the vacuum created.

Vprocess - Hadoux

The frame is lifted from the master model while maintaining the vacuum. The lower film remains in place on the frame, the vacuum maintained guarantees the shape and strength of the mould.

Vprocess - Hadoux

The same process is applied to the other part of the mould, which can receive cores.


Vprocess - Hadoux

The two frames are assembled and fixed.

Vprocess - Hadoux

The vacuum is maintained during the casting process and until the end of the solidification time of the metal.

Vprocess - Hadoux

The mould is released when it is put under atmospheric pressure.


The remaining plastic films are recycled and 99% of the sand is recycled directly into the system.
