How do you control the quality of aluminum alloy doors and windows during production?
To ensure the quality of broken bridge aluminum doors and windows, profiles, and sawing are the two most critical links. Among them, in the selection of profiles, the quality of the internal insulation strips of broken bridge aluminum is crucial.
Because this will directly determine the thermal insulation performance of doors and windows. At present, PA66 nylon is the mandatory standard for the use of insulation strips inside broken bridge aluminum doors and windows.
Of course, we do not deny that there are insulation strips made of PVC plastic in the market. Although this will reduce costs, it will only "shoot itself in the foot" in the end.
Secondly, when sawing broken bridge aluminum profiles, due to the special structure of the profile, a layer of insulation strips is sandwiched in the middle, so special attention should be paid when choosing saw blades for sawing.
For the sawing of broken bridge aluminum profiles, to ensure the sawing accuracy and surface finish, it is still necessary to "leave professional things to professionals".
Among them, using professional broken bridge aluminum saw blades to saw broken bridge aluminum profiles can effectively ensure the sawing effect. The sawing is burr-free and the sawing accuracy can meet all market requirements.
As for the aluminum saw blade, the saw blade manufacturer specially developed and produced the saw blade for aluminum processing, which makes the performance of the saw blade very outstanding.
Among them, the aluminum saw blade adopts an imported SKS steel plate, which effectively ensures the cutting performance of the saw blade. Under high-load operating pressure, it can effectively ensure that the saw blade can run stably without accidents.
Of course, for the sawing of aluminum profiles, in addition to choosing the right profiles and saw blades, we should do a good job of lubricating and cooling the saw blades during the whole sawing process, which will greatly extend the use time of aluminum saw blades.
At present, to effectively control the quality of aluminum doors and windows, adding a micro-lubrication device to the sawing process to cool the saw blade is the best solution to solve the problem of the life of the saw blade and the reduction of cutting effect due to heat.
