How to solve the bubble problem of aluminum profile processing products

Aluminum processing products are widely used in today's life, but many aluminum processing, indicating that it is easy to produce bubbles, today, Caixin aluminum products for the surface of aluminum processing products bubble problem, talk about the solution. First of all, we should know what is the cause of the bubble on the surface of the aluminum profile processing product. In the processing of aluminum profiles, the internal gas or the air involved in the extrusion process will expand in the subsequent process of some processes, especially when extrusion and heat treatment, resulting in the surface of aluminum profiles, resulting in the formation of some processed product defects. The solution to the bubble problem on the surface of aluminum processing products mainly has the following points: 1, minimize the air content inside the aluminum alloy casting rod. 2, to ensure that the aluminum alloy casting rod surface clean, no oil. 3, aluminum alloy bar temperature can not be too high. 4, clean the extrusion cylinder to prevent air in the extrusion process. 5, increase the thickness of the residual. 6. Control the amount of lubricating oil during processing to avoid excessive lubrication. The main method to solve the bubble problem of aluminum processing products is the above several, and pay attention to these problems above, in order to produce qualified aluminum products.
