EPS blocks and sheets manufacturing equipment

Clinker Panel

Insulated Concrete Forms (ICF) manufacturing equipment

Molded styrofoam

Blockmolding machine

is designed for the final EPS beads expansion.

After the preexpanded beads have been fed to the blockmold, they get thermal treatment. As the result the beads get expanded thus molding into an EPS block inside the machine. Saturated steam is used there as heat carrier.

Blockmold charging is automatically controlled and effected through charging valves by suction. The valve is actuated by pneumocylinder (Camozzi, Italy). It is compulsory to use the vacuum system for the cooling and stabilization of the block inside the machine.
Once the block has cooled it is knocked out either by pneumocylinder or by means of pressurized air (air cushion) depending on the blockmold design.

Our company manufactures two types of blockmold: an open and a closed-type machine.
Their primary difference is the dimensions of the block produced and their output.

Notes:
* Steam generating equipment must maintain the pressure of 5...7 atm, steaming capacity being not less than 200-250 kg/h;
**Pneumocylinders are manufactured by CAMOZZI company (Italy). A Pg =10 atm compressor, with the output not less than 0,16m3/min and the receiver volume of 60 l is necessary to ensure stable functioning of the pneumatic system. 

OPEN-TYPE UNFB-05 BLOCKMOLD

/images/oborudovanie_pps/open_forma.jpg

The machine volume is divided into a process chamber and cooling section. Once the block has been molded inside the process chamber, it is moved to the cooling section by means of a pneumocylinder-driven pusher. The process chamber is then loaded with raw material again, and the molding cycle repeats.  

The machine operates in the batch-continuous mode. During one cycle a part of the block which is getting molded inside the process chamber is stuck to the previously molded block inside the cooling section. The boundary strength is equal to the strength of the main EPS block. Thus a theoretically infinite EPS bulk comes out of the blockmold and it can be cut into blocks of necessary length.
Standard length of sliding rails is for the 2000 mm long blocks. It can be lengthened to 3000 m on request.

The design of the blockmold is covered by the Patent No 40019.
Manufacture, sale and operation of the blockmolds of such design produced by the manufacturer other than Vyatkastroydetal holding company is persecuted under law.

CLOSED-TYPE BF-12 and BF-15 BLOCKMOLDS

The whole blockmold volume is a process chamber. The molding cycle is similar to that of the open-type blockmold:

After the vacuum treatment/cooling cycle has finished the end door opens and the block is knocked out by pressurized air and on to the carrier to be transported to the cutting site.
The primary advantage of this blockmold over the open-type machine is its higher output thanks to a bigger volume of the process chamber (2,5-3 times bigger depending on the design chosen).
However, limited length of the blocks it produces can also be its disadvantage.

OUR COMPANY CAN MANUFACTURE BLOCKMOLDS WITH NON-STANDARD DIMENSIONS ON REQUEST.
