What Are the Causes of Industrial Aluminum? -WJW Aluminum Supplier Aluminum

Industrial aluminum crispness has always been a factor that plagues the abnormal management of some profile enterprises. Industrial aluminum crispness more or less affects the market share and user reputation of these profile companies, and to varying degrees depends on the appearance or identification level of the door and window assembly plant. Industrial aluminum is divided according to the application field. Industrial aluminum refers to all aluminum profiles other than building doors and windows, curtain walls, indoor and outdoor decoration and building structure.

The crispness of the profile is basically reflected in the physical and mechanical functions of the product. Its important feature is that the collapse and cold shock cracking during the tailoring process have the following reasons for the poor physical mechanical properties of the profile:

1. Unfair formula and hybrid process

1. Too much packaging

2. Increase the type and quantity of impact modifiers

3. Too much or too little fastener

4. Too many external lubricants

5. The order of thermal hybrid, the setting value of the temperature, and the time of maturity time on the section also have a decisive effect.

2. Unexplained squeezing process

1. The moderate or not plasticized of the material

2. Insufficient head pressure

3. The low molecular components in the product are not discharged.

4. The screw torque is too low

3. Unfair mold design

1. The cross -section design of the mold is unfair, especially the dispersion of the internal tendons and the treatment of the interface angle, which will lead to the existence of the stress concentration scene. It is necessary to improve the design and eliminate the right angles and sharp angles of the interface.

2. Insufficient mold pressure, industrial aluminum materials are divided according to the application field. Industrial aluminum profile refers to the elimination of building doors and windows, curtain walls, indoor decoration, and all aluminum profiles outside the building structure. It is determined by the length of the mold. On the one hand, the change of mold pressure may adjust the flow resistance by changing the length of the mold segment; on the other hand, you can choose a different tightening ratio in the mold design stage to change the extrusion pressure, but it must be noted that the tightening ratio of the mold should be squeezed with the squeeze. The tightening of the screw screw is compatible; it can also change the melt pressure by changing the formula, adjusting the extruded process parameters and adding porous boards

3. The functional implementation of the functional landing caused by the poor convergence of the divergent tendons should be solved by properly increase the length of the tendon and the nominal tendon, at the intersection of the tendon and tendon, or to improve the tightness. Industrial aluminum profiles are divided into application fields. Industrial aluminum profiles refer to all aluminum profiles other than building doors and windows, curtain walls, indoor and outdoor decoration and building structure.

4. The outlet of the mold is uneven, resulting in inconsistent wall thickness and thickness of the type of material, or inconsistent compactness. This also causes the difference in mechanical functions on both sides of the profile. Sometimes we will hit it once, but it also proves this. There are no more discussions here for non -standard profiles, such as thin walls.

5. Cooling speed of the crystal device. The temperature of cooling water is often not enough to cause sufficient weight. The role of cooling water is to cool in time and set the large molecular chain drawn by profiles to achieve the purpose of use.
