Stripping for thermal insulation aluminum profiles

Stripping is the insertion of thermal breaks in between two aluminum profiles. These profiles provide excellent insulation for windows and doors and help to conserve energy and reduce the cost of heating and cooling a building.

The initial setup of the stripping process involves setting the correct information on the computer and testing the values used for different axes on the machines. After the initial setup and computer simulation, the operators can begin the process of loading the profiles unto the machine.

The two aluminum profiles that will be used to form the final product are placed on the table and they are fed into the machine for tapping with the aid of a conveyor. The machines for the application of the protective tape are located at the beginning of the process. The tape is pressed on the profile and then cut off.

Next, the two profiles are combined with the insulating strips in a process called nailing. During the nailing process , the strips may be pressed into the profiles or the strips can remain stationery while the aluminum profiles slide into them. First, an operator secures the strips for the thermal break by insert them into the corresponding mount holes. Then the lower profile is transported into the nailing section where they are positioned precisely. The second profile to be inserted is placed on the table and moved towards the strip and the first profile with a conveyor. Then the three parts are aligned to flush.

The aligned assembly is transported to the rolling machine. The open sections are closed in the rolling machine, where the marking of the strips is also performed. After the rolling process, the strips are tested to determine the maximum shear force. This is repeated at regular intervals, especially for the first batch in a series. The shear force is directly related to the strength of the windows and doors that will be framed with the thermally insulated profiles.

After the profiles come out of the rolling process they are moved to the temporary holding zone or they are moved directly to the packing area.

Packing of the aluminum profiles usually involves wrapping them individually on a machine with self-adhesive tape. This tape is usually wound around the profiles with a machine as the profile moves longitudinally through it.

Before the final bundling and loading of the profiles for delivery, they are carefully inspected. At this point, they are subjected to a manual check. The operators look at the strips and ensure that they are firm before they are packed and wrapped with nylon.

At the packing area, the profiles are arranged in bundles to meet the specification and packaging requirements of the customer. These bundles are usually wrapped with stretch nylon and wooden strips that can protect the profiles from damage while they are being transported or shipped to the customer.

The process just described is for profiles that have just one thermal break.  The same process can be used for profiles with two thermal breaks which are used for windows with up to three panes.
