Cold press mod. PCV 400BRK/V, four columns with pressing stem plunger type and quick opening, for the production of brake pads for cars and CV.  Cold and warm molding.

The press is fitted with:
Volumetric compound loading shoe
This device is permanently in contact with the matrix bearer plate. The sliding of the shoe is made by an hydraulic cylinder. The loading phase can be repeated more times, making easier the loading of the fibrous compounds. The compound loading chambers are created by a vertical movement of the matrix (the size of the chambers may vary, but staying within the field of the matrix sliding), which determines the size for each type of moulding. The control of the chamber opening is made by a linear transducer and positive stop in a manually adjustable dimension.  Each loading shoe will be equipped with a matrix polishing brush and a dust suction collector. 

Fixed punch mould-holder
This device has been especially studied in order to make the mould change easy and quick (approximately 4 minutes for the entire operation). The front part of the matrix can be opened on the front to help placing the mould. Inside the matrix there are two references for the correct position of the cavities. In the lower part, and more exactly on the lower reaction plate of the machine, there is a plate with balls. Such plate makes it easier the sliding of the matrix and punch group during the positioning of the mould holder matrix.

- The cycle time will be approximately 18 seconds with a double-cavity mould.  
- This cycle time is calculated according to pads with a surface not bigger than 50 cm² each (pads for cars) and with a not particularly fibrous compound.
- For pads with a surface bigger than 65 cm² we advise the production with a single cavity mould.
