Precautions for using gravity casting machine

　　The Gravity Casting Machine pours molten metal heated to a certain extent into a gravity Casting mold under the action of gravity, and then processes it into a casting. Since the molten metal needs to be heated during casting, and molten metal like aluminum needs to be heated to a high temperature of 660°C, in order to avoid safety accidents, the following points need to be paid attention to when using a gravity Casting Machine.

　　Casting personnel should wear overalls and protective glasses and prepare the site where molten metal will be cast. Passages must be clear, gravity casting mold operations must be operated in strict accordance with specifications, and skills training must be certified. Because once molten metal or castings come into contact with the human body, workers will be burned. Once they encounter any flammable and explosive items, it is very dangerous.

 

　　After the pouring is completed, the pouring personnel should also pay attention to cleaning the equipment in time, and pay attention to protection during the cleaning work to avoid damage caused by high temperature. Because the gravity casting machine itself is very professional, it is easy to leave many safety hazards if you are not careful. Therefore, foundry workers must strictly demand their own safety and try to avoid safety accidents.

 

　　Inclined gravity casting machines can be used in many industries such as the production of medical devices, tableware, auto parts, electrical accessories, etc. However, by pouring molten metal into a gravity casting mold placed on a gravity casting machine, the molten metal is heated for production. But before casting, manufacturers need to preheat gravity casting molds. Do you know why?

 

　　Due to the thermal conductivity of metal gravity casting molds, gravity casting molds cannot be cast directly without preheating operations. During the casting process, the cooling rate of the aluminum liquid will accelerate, and the fluidity of the aluminum liquid will decrease rapidly, which can easily cause surface defects such as cold shut, poor pouring, and pores. , also affects the performance of castings. The increased mass of a gravity casting mold due to stress.

 

　　Generally speaking, tilt gravity casting machines are preheated before casting. The preheating temperature is usually determined by the material, type and structure of the casting. The preheating temperature of the gravity casting mold will vary under different circumstances. The molds on gravity casting machines for this technology are usually heated to over 150 degrees with a blowtorch.
