How to Analyze the Surface Defects of Industrial Aluminum Profile? -Ruminum Profiles Supplier

The following content of the editor refers to the surface of the air bubbles produced by the industrial aluminum squeezing process, not the casting due to osteoporosis. Of course, cast looseness may be such an important cause, but it is by no means a decisive influencing factor. During the squeezing, the cast pine may form a large amount of air bubbles on the surface of the aluminum profile during the heat treatment process. Keeping more and quenching in the squeezing bubble, and it will not develop anymore.

1. The generation of bubble squeezing air bubbles: When there is a certain gap between the development of the ingot and the squeezing cylinder, it will start to be staged through the squeezing analysis stage, that is, when the casting is thick, if we cannot make the ingots from going from the back, we can follow in turn in turn. After researching deformation, discharge the air from the air in the gap, it is possible that a compressed air bubbles are not formed between the tube wall and the surface structure of the ingot. At the same time, between the ingots and the squeezing tube wall, a compressed or cone -shaped friction zone and a dead area occur, and the plastic deformation of cutting and deformation. Cracked moment. When a compression with a huge pressure produces a bubbles and meets this tiny crack, the compressed air bubble technology may need to break through the shell and invade the micro -crack. After squeezing out, stretch deformation, form a bubble on the surface of the industrial aluminum profile. Sometimes when you can hear the "explosion" sound compression, the foam is broken. The gap between the ingots and the squeezing cylinder is getting larger and larger, the more severe the grinding of the squeezing cylinder and extrusion cushion. , The greater the chance of forming a surface when squeezing. Sometimes, this kind of bubbles are squeezed out of the direction, a large turn small cluster is distributed on a straight line. Reduce the gap between the ingots, the extrusion cushion and the tube wall, and reduce the amount of air surviving in the squeezing cylinder in society; prevent the pollution of the squeezing cylinder due to lubricants; The material is heated and appropriately slows down the company's thick speed through the stamping analysis phase, and realizes the rough deformation of the ingot from the front to the back in turn. The air system is discharged out of the squeeze. Formation of bubbles.

In addition, when the diversion mold is squeezed, the next profile at the junction of the industrial aluminum profile will produce a squeezing bubble. This usually occurs on the surface of the aluminum. Due to the separation of the residual material, the price is removed from the top, and the price of the naked discharge is removed, and the excess metal that is directly connected to the profile in the diversion mold cannot be eliminated, leaving a space on the upper structure of the mold hole. The next profile is squeezed out to disturb the ingot mold closed to increase the pressure of the gas space, leaving bubbles on the surface of the contour of the head. Of course, if we can enter the side, we can enter from the side, and the bubbles will be left in the development of the separation. This kind of bubbles can be slightly reduced, but the students are more financially difficult to eliminate students. However, this bubble is not very serious. It only appears on the head. After cutting, it will not hinder use and affect the rate of finished product, but the impact is not significant. 2. If the bubbles are ruptured during the squeezing process, the metal layer of the metal back becomes a separate layer. After the separation layer is peeled off, the metal surface is removed, so that the metal surface will be shiny.

In addition, in addition to the bubbles, the squeeze tubes are contaminated, and the walls of the squeezing tube are severely abrasive. There are too many metals in the tube, and the cleaning is not clean. Remove the residual metal covered by the surface covered by the new industrial aluminum profile, so that the aluminum profile will be peeled. However, subcutaneous pollution is contaminated and loses metal luster; or has not been polluted, but new and old companies cannot develop closely and combine it, destroying the continuous use of domestic metals.
