Description

Technical field [0001] The invention belongs to the field of aluminum and aluminum alloy processed parts, and in particular is a very environmentally friendly water-based mold release composition. Background technique [0002] Pressure casting (abbreviated as die casting) is a metal casting process, and the mold release composition is a release agent used for stamping aluminum alloy, magnesium alloy, zinc alloy and other metal alloys under high pressure and high speed conditions. Pressure casting has the technological characteristics of high production efficiency, short production process, high casting finish and strength, less machining allowance, and metal material saving. [0003] Die castings have a wide range of applications, involving a considerable number of product fields and industrial categories. In this application, considering the large quantity, variety, high requirements, and large amount of metal materials, the automobile industry should be the first choice. Die ca...
