The function of the cast aluminum door is the most practical and fundamental problem. The good and bad of the door are mainly the later use. Commonly used functions include: door opening performance, door insulation performance, door sound insulation performance, door fire performance, door anti-theft performance, external door wind pressure deformation performance, external door air permeability and rainwater seepage Leakage performance, overall strength of the door. These are the top issues we consider in our design. Design time - the use function of non-standard doors should be determined for different use places and use parts of non-standard doors. Then, these features are reflected in the design process. In order to achieve these functions, it is usually considered in both material selection and process. In the selection of materials - usually use the raw materials with higher damage strength; choose raw materials with looser structure, better insulation and sound insulation; choose non-flammable or flame-retarded raw materials. From the process - consider the nodes that facilitate the above functions. For example, a sealing strip is added at the joint between the door frame and the door leaf, the door leaf and the door leaf; the joint between the door frame and the door leaf, the door leaf and the door leaf ensures a suitable gap and other suitable structures.
