With our continuous pre-expansion, polystyrene is performed with a continuous cycle in the first expansion. This is of great importance as the starting point for optimal manufacturing of foamed products.
In the end, the density of the raw material is decisive for the weight of any product you produce, for example:
It is possible to produce a 200 ml drinking cup with a weight of 2 grams, while a weight of 1,5 grams is an option as well, using the same machine and moulds.
We offer a wide range of pre-expanders with varying capacities.
The automatic processing cycle begins with the inlet of raw material into the expansion chamber through the dosing hopper.
The expanded material, coming out from the expansion chamber, will be discharged by gravity into the fluidized bed and dried by means of hot air blowing. From here, the material will be conveyed to the storage silos.
Machine control is made by a main electro-mechanical and digital panel.
A precise measuring and adjustable steam/air flow device in combination with a rockwool insulation cover of the expansion chamber assures a very cost-effective use from the perspective of energy consumption.
