近年来，铝板市场的需求越来越大，市面上也出现很多新的铝板厂家，可是由于技术不过关，没有生产经验，生产出的铝板不合格，产品质量不过关，导致铝板发脆，那么是什么导致铝板发脆的原因呢？
In recent years, the market demand for aluminum is more and more big, a lot of new aluminum manufacturers also appeared on the market, but because the technology does not pass, no production experience, the production of aluminum unqualified product quality, resulting in aluminum brittle, so what is the cause of brittle aluminum?
1、铝板生产厂家对于因分流筋汇合不良造成的性能下降应适当增加筋与外表面、筋与筋汇流处的长度，或者增大压缩比来解决，模头压力的改变可以通过改变模头平直段长度来调整流料阻力。
1, aluminum manufacturers for shunt performance due to reinforcement caused by poor confluence decline should be appropriate to increase the rib and the outer surface, tendon and tendon at the confluence of the length, or increase the compression ratio, die pressure change can be adjusted by changing the flow resistance of the die head straight length.

2、定型模的冷却速率，冷却水温往往没有引起足够的重视，冷却水的作用是将型材拉伸的大分子链及时冷却定型,达到使用目的。
2, the cooling rate of the mold and the cooling water temperature often fail to attract enough attention. The role of cooling water is to cool the profile chain in time and achieve the purpose.
3、口模截面设计不合理，尤其是内筋的分布和交界面角度的处理，这样会造成应力集中现象存在，需要改进设计和消除交界面处的直角和锐角。
3, the section design of the die is unreasonable, especially the treatment of the distribution of the inner reinforcement and the angle of the interface. This will cause the phenomenon of stress concentration. We need to improve the design and eliminate the right angle and sharp angle at the interface.
4、口模出料不均匀，造成型材壁厚薄不一致，或者密实度不一致，这也就造成了型材两个面之间的力学性能上的差别。
4, the die material is uneven, resulting in inconsistent thickness of the profile wall, or inconsistency of density, which results in the difference in mechanical properties between the two surfaces.
5、模头压力不足，模头处压力大小是直接受模具的压缩比，特别是模具平直段的长度来决定的。模头的压缩比太小或平直段太短都会造成铝板制品不致密，影响物理性能。
5, the pressure of the die head is insufficient and the pressure of the die head is directly determined by the compression ratio of the die, especially the length of the die flat section. The compression ratio of the die head is too small or the straight section is too short will cause the aluminum plate products to be not dense and affect the physical properties.
