Points for attention to the processing of doors and windows

    After the semifinished product is assembled and checked, the packing can be held after the liquidation is clean and the seal on the product is covered.

    In the process of production, technicians should do every process standard, because the waterproof performance of aluminum alloy doors and windows is not waterproof material itself, and every connection point must be waterproof film, and glass must be sealed with glass glue inside and outside.

    In the production process is the most important attention to the size of the problem, to have installed a good tune, avoid too tight or too loose doors and windows.
