Casting classification
Casting classification :
(1) Sand Casting
Sand-type casting: casting method for producing castings in sand type. Steel, iron and most colored alloy castings can be obtained with sand casting methods.
(2) Melting casting (Investmentcasting)
Melting casting: generally refers to the molding surface of the easy-melt material, coating a plurality of refractory materials in the mold surface, and then melting the discharge type shell, thereby obtaining a cast shape of the non-profile surface, calcined by high temperature The casting plan of the sand can be filled. Often referred to as"Doux Casting".
(3) Pressure casting (DIE CASTING)
Die castingYES: It is to press the metal liquid in a precision metal mold type cavity using high pressure, and the metal fluid is cooled under pressure to form a casting.
(4) Low Pressure Casting
Low pressure casting: means that the liquid metal is lower(0.02 ~ 0.06 MPa) The mold is filled under the action, and the method of crystallizing under pressure to form a casting.
(5) Centrifugal casting
Centrifugal Cast: It is a casting method for pouring a mold in a rotating cast shape and a casting method for filling the mold under centrifugal force.
(6) Metal casting (Gravity Die Casting)
Metal molding: means a molding method for obtaining a metal casting in gravity and cooling solidification in a gravity.
(7) Vacuumdie Casting
Vacuum Cast: By eliminating the gas in the die-casting mold cavity in the die-casting mold, the pores and dissolved gases in the die castings are eliminated, thereby increasing the mechanical properties of die casting and the advanced die-casting process of surface quality.
(8) Squeeen Die Casting
Extrusion Cast: It is a method of solidifying liquid or semi-solid metal in high pressure, flow forming, directly obtaining a member or blank. It has the advantages of high liquid metallic utilization, simplification and quality stability, and is a metallic forming technique with potential application prospects.
(9) Disappeared mold casting (Lost Foam Casting)
Disappearing molding (also known as real casting): is a paraffin or foam model with a mold size shape, a mold cluster, brushing the refractory coating and dries, buried in dry stone sand, vibration shape, is negative Pouring the casting, gasifying the model, the liquid metal occupies the position of the model, and the new casting method of the casting is formed after cooling.
(10) Continuous Casting
Continuous casting: is an advanced casting method, which is the molten metal, continuously cast into a special metal type called the crystallizer, solidified (casser) casting, continuously from the crystallizer One end is pulled out, it can obtain a casting of any long or specific length.
