The process of cutting the PU Foaming plant specialized files that include the shape drawing. For 2D shapes a DXF file is required, while for 3D shapes an STL file is needed, which allows to rotate the shape and see all the angles of it for better accuracy.
Once the right file is received, the data is entered into the computer which is connected to the foam cutter, including all the coordinated needed for cutting that specific shape. Upon finishing of cutting the shape needed, it can be sanded to either a rough or a smooth finish, according to the customer's request. Large scale shapes are made in several pieces, then glued together to make the complete shape. The cut can also be coated with Polyethylene coating, Polyurea and paint it if needed. The end product needs to be durable, strong and long lasting.
This is the heart of any spray foam machine. It is the part that creates the foam by proportioning the components and pushing them further. The best one for all around use would be an electric one, but make sure it has intuitive controls and balance pressure valves.
The spray foam hoses:
These are basic hoses, which have the sole purpose of transporting the foam from the proportioner to the spray gun. The hoses come in different colors, diameters and lengths, and it's always a good idea to use hoses that are corrosion protected, to prevent any nasty surprises.
The spray foam gun:
If the proportioner is the heart of the installation, then this is the hand. Inside the gun, the two components of the foam are mixed and expelled at certain pressures towards the surface to insulate. The moment the two components come into contact they react, so care must be taken after usage, to avoid clogging. Therefore, before buying one, try and find out how easy it is to clean.
Al these Full servo door panel forming line will help you succeed in insulating your house. Spray foam insulation can be used instead of foam board insulation, but you should take into account all the advantages and disadvantages of the two insulation methods.
The foam machine is without a doubt the most important part of the entire setup and consequently the most expensive. The purpose of the machine (also called the proportioner) is to heat and proportion the two components of the spray foam chemicals to an exact 1:1 volume and pass that along the heated hose.
The gun is what is connected, via the heated hose to the machine, that takes the chemicals, keep separate until they reach the gun, and mixes them together and sprays them out onto the desired surface. The guns most often operate with approximately 100cfm of supplied air in order to properly spray the chemicals and create a good, even mix of the material.
The hose which is connected between the foam machine and the foam gun, is a two hose design that keeps the material, the A and B component, both separated and heated while it travels the desired length which is typically around 200ft, not to exceed 400ft. The hose is a necessary item because the large foam machine is often mounted into a mobile spray foam rig/trailer and then the hose is pulled into the house or building so the desire area can be sprayed.
The Multi-station Thermoforming vacuum form machine are just that, they are two separate air driven pumps that are placed in the spray foam chemical drums, one in the A and one in the B component (55 gallon drums) and pull material from the drums and feed it to the machine which starts the heating and proportioning process.
