Casting

Katrangan

Casting minangka proses manufaktur sing bahan cairan biasane diwutahake menyang cetakan, sing ngemot hollowcavity saka bentuk sing dipengini, lan banjur diidini padhet. Partis solidified uga dikenal minangka casting, sing dibuwang utawa rusak saka cetakan kanggo ngrampungake proses kasebut.

Logam sing paling umum sing diolah kanggo casting yaiku aluminium lan besi cor. Nanging, logam liyane, kayata baja tahan karat, baja campuran, tembaga, kuningan, magnesium, lan seng, uga digunakake kanggo ngasilake casting ing pengecoran.

Casting is most commonly used for making complex shapes that would be difficult or uneconomical to make via other methods. The casting process typically includes 4 steps - cutting, forming, assembling, and surface treatment.

-Mold making 

In the casting process, a pattern is made in the shape of the desired part. Simple designs can be made in a single piece or solid pattern. More complex designs are made in two parts, called split patterns. The pattern is made of wax, wood, plastic, or metal. The molds are constructed through several different processes depending on the type of foundry, metal to be casted, the number of parts to be produced, size of the casting, and complexity of the casting. 

- Melting 

Melting is performed in a furnace. The process includes melting the charge, refining the melt, adjusting the melt chemistry, and tapping into a transport vessel. Refining is done to remove harmful gases and elements from the molten metal to avoid casting defects.  

-Pouring  

In a foundry, molten metal is poured into molds. Pouring can be accomplished with gravity, or it may be assisted with a vacuum or pressurized gas. 

- Shakeout 

Komponen logam sing padhet banjur dicopot saka cetakan. Yen cetakan adhedhasar pasir, iki bisa ditindakake kanthi goyang utawa digulung.

- Degating 

Gelar yaiku nyopot kepala, balapan, gerbang, lan riser saka casting. Para pelari, gerbang, lan riser bisa uga ngilangi obor, pita, utawa pisau keramik.

-Ngobati panas

Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material.  

-Surfacecleaning

Sawise degating lan perawatan panas, wedhi utawa media cetakan liyane bisa uga tetep ana ing casting. Kanggo ngilangi sisa-sisa cetakan, lumahing wis di resiki nggunakake proses blasting. Akeh bahan sing bisa digunakake kanggo ngresiki permukaan cast, kalebu baja, zat besi, logam campuran liyane, oksida aluminium, manik kaca, cangkang kenari, bubuk manggang, lan liya-liyane.

- Finishing

Langkah pungkasan ing proses casting biasane kalebu mecah, sanding, utawa mesin komponen kanggo nggayuh akurasi dimensi, bentuk fisik, lan finish permukaan sing dipengini.

Except providing our clients with casting parts, most of products Auwell supplies with further machining and surface treatment service.

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. Generally, Auwell does not offer forging, but only using forged parts as pre-material for further processing.
