In the process of processing Shandong Aluminum alloy die castings, we often cause various quality problems due to improper operation and other reasons. Today, aluminum alloy die-casting manufacturers mainly help you to solve the problems of collision and leakage.
The surface of aluminum alloy castings with bumps is the surface of castings with bumps, which can be seen directly by visual inspection. This may be caused by the workers of aluminum alloy die casting factory in the process of gate removal, correction, cleaning and handling. The manufacturer reminds the workers to clean the castings carefully. The castings should not be stacked or collided during storage and transportation. Special storage and transportation boxes should be used.
Leakage of aluminum alloy castings is mainly caused by water leakage, air leakage or water seepage, which needs to be judged by air tightness test during cleaning or trial processing. The leakage causes of aluminum alloy die casting were summarized, including insufficient pressure, poor exhaust, improper alloy selection, unreasonable gating system design or unreasonable casting structure. The way to solve the problem is to suit the remedy to the case, increase the specific pressure, avoid machining as far as possible, impregnate the castings, select the alloy with good quality, and improve the gating system and exhaust system.
