Electrical panel sealing foam injection machine is a very important and practical preventive measure in the industrial environment, which in addition to creating security and health for workers and electrical technicians, has a great impact on increasing the lifespan of electronic systems and electrical panels. Metal doors and sometimes plastic sheets are used on the doors of the switchboards and prevent the penetration of dust into electronic circuits and boards. These doors are not completely impermeable and therefore the use of polyurethane sealing foam is recommended. The sealing foam is made of polyurethane, which is used for electric doors, refrigerators, freezers and fireboxes. The foam injection machine produces injectable polyethylene foams by receiving a material with a liquid state (polyL, polyiso cyan, etc.) and performing special chemical reactions on them, and is ready to use it with very high pressure in the injection molding process.
