Discussion on deformation causes and production standards of aluminum profiles (Dongguan Aluminum Factory)

The extrusion deformation process of aluminum profile in Dongguan Aluminum Factory is a very complicated process, including elastic-plastic, rigid-plastic and viscoplastic deformation processes. In the traditional finite element analysis technology, the relative deformation rate is too high, and it is difficult to realize grid division. The extrusion die for national standard aluminum profile is a unity with the characteristics of strength die and the requirements of stable flow field die.

Up to now, there is no complete theoretical system for the design of aluminum extrusion die. Many aspects are based on experience, and human factors play a decisive role in design. The quality of extrusion die design mainly depends on the designer's experience, so it is difficult to verify theoretically in advance. Only after the mold is put into production can we evaluate and analyze the product quality. If the product quality is not good, it must be repaired, which will inevitably increase the design and manufacturing cost. For inexperienced designers, they will find it more difficult.

Because of the above characteristics, people have more perceptual knowledge than rational knowledge about the extrusion deformation process of national standard aluminum profiles. In the world aluminum processing industry, the design of extrusion die for national standard aluminum profile is still mainly based on experience design, and the theoretical design analysis is still in the primary auxiliary stage.

In China, the design engineering practice of national standard aluminum profile extrusion die is far ahead of the theoretical design research of national standard aluminum profile extrusion die.

Discussion on production standard of aluminum profile in Dongguan Aluminum Industry

1, industrial aluminum profile refers to other aluminum extrusion profiles used for building doors, windows, curtain walls, indoor and outdoor decoration, in addition to general products implementing their public specifications.

2. If there are special requirements for the dimensional deviation of industrial aluminum profiles, it shall be indicated in the contract.

3. Where there are no national standards, industry standards and central standards for products consumed by enterprises, corresponding enterprise standards shall be formulated as the basis for organizing consumption. Enterprise standards shall be filed in foreign technical supervision bureaus in the order of rules, and the quality and technical supervision system shall be managed in the territory. After monitoring the sampling market, you need to go to the Bureau of Quality and Technical Supervision where the enterprise is located to read the filing standards before you can judge whether it is qualified.
