The application of expanded polyurethane foam has definitively marked a turning point in the industrial and building insulation fields, imposing its technologic validity. It is mainly used for the production of pre-fabricated panels in both discontinuous and continuous process.
Discontinuous Process
This process is adopted to produce panels of different thickness and dimensions. For this production presses able to produce panels up to 14m long and 200mm thickness are being used.
Panels width varies from 0.5m for doors up to 2.50m for refrigerant container.
Both rigid and/or flexible substrata are used, with smooth or grooved profiles according to individual customer's requirements.
Production processes:
manual side injection system with closed press
LANCIA automatic injection system with closed press
automatic injection system with open pour technique
Continuous Process
This process allows a large scale production of different type of panels with flexible or rigid substrata. For industrial production, it is certainly more convenient for both the quality and quantity aspects over the discontinuous process.
The most current foaming systems using c-pentane as an alternative blowing agent are provided with specially designed safety systems to avoid any possible explosion danger.
Production processes:
PU distribution traverse
heated pouring platen with view for the suction plant
double belt conveyor
high pressure 4 component foaming machine
band saw cutting machine with sound-proof cabin
paper substrata panels production plant
metal sheet panels production plant
