20 series aluminum extrusion.Maintenance methods for die casting mold accessories

　　The maintenance of die-casting mold accessories is also a noteworthy item. Proper maintenance of die-casting mold accessories can extend the service life of die-casting molds and provide quality assurance for the production of die-casting parts.

　　There are several maintenance measures. Firstly, the use of anti oxidants. When heated, the anti oxidants will form a protective film on the surface of the mold parts. The mold parts will fall off during cooling, annealing, and discharging, which will not affect the cooling of the mold parts. They only serve to protect the mold parts. Large and medium-sized parts are suitable for brushing, while small parts are suitable for soaking. 2、 Using a well type gas carburizing furnace for heating, accessories with excessively long dimensions are suitable for heat treatment using this heating method. Simply place them on the bottom plate of the crucible and fix them vertically for heating. The furnace temperature can reach 800 degrees to protect the accessories from oxidation and decarburization. 3、 The application of stainless steel coated paper. Stainless steel coated paper is an ultra-thin stainless steel foil that can be folded like paper and has the characteristics of high temperature resistance and good sealing performance. Simply wrap the mold accessories with stainless steel coated paper and put them in the heat treatment furnace.
