METAL CASTING ENGINEERING ELEMENTARY COMPETENCY 2 UNSTRESSED CASTING METAL CASTING ENGINEERING CLASS XII/ SEMESTER 5 ELEMENTARY COMPETENCY 2

Pouring Process Pouring process ( casting) is impregnation of mold cavity with casting material which has been melted ( liquefied) Teknologi dan Rekayasa

Centrifugal Casting Pouring process ( casting) with centrifugal method done at casting by using metal mold ( die casting) Not all form of casting substances can be done with this method Symmetrical and cylindrical integer substances as according to its(the construction earns in cast with this centrifugal method Teknologi dan Rekayasa

3 Kinds of centrifugal casting : Vertical Centrifugal casting Horizontal Centrifugal casting Semi centrifugal casting Teknologi dan Rekayasa

Centrifugal Casting Prinsip kerja : Liquid metal is infused [by] mold cavity Metal mold is turned around by using high revolution from ice [by] Liquid metal that is enough is weight will be thrown exit from position of pouring Liquid metal filled form of ice as a form of work substance which we desire Teknologi dan Rekayasa

Vertical Centrifugal Casting Teknologi dan Rekayasa

Horizontal Centrifugal Casting Teknologi dan Rekayasa

Andvantage of Sentrifugal Casting Massive pouring result Equiamplitude surface of smooth casting Can form casting wall at thin scale Teknologi dan Rekayasa

Continuous Casting Is pouring continues Yields casting substance is length which can be cut as according to requirement of work substance Formation of small fairish division Yields product with good grade Teknologi dan Rekayasa

Work Principle of Continuous Casting Liquid metal poured at parallel division with passage at vessel Liquid metal streams into in mold ( Mould) from tubular copper material along the length ± 1m with wall arranged in layers with chromium, part of this equiped also with cooling water. Teknologi dan Rekayasa

Work Principle of Continuous Casting After casting pass mold also is made cool later on pulled and pointed by special roller ( straightening roller) After coming up with system pemotongan(flying shears), coran will be cut matching with the one which is wanted Teknologi dan Rekayasa

Work Principle of Continuous Casting Teknologi dan Rekayasa

Gravity Die Casting Gravity die Casting ( bulk pouring) is pouring process of liquid metal kedalam mold by the way of poured [by] through mold passages which has been provided at mold by using pan decants ( ladle) Teknologi dan Rekayasa

Invesment Casting Mold applied from sand cetak(sand casting) Cupola material is selected having point of low liquid ( candela) For making of substance with level of high complication 1 cupola for 1 times pouring Teknologi dan Rekayasa

Invesment Casting Process Cupola ( from wax) made by the way of injection at metal mold Wax model is arranged in layers with sheating like ethil or silicate sodium to refine model equiamplitude surface. Cupola is placed ( invested) in mold material like resin sand Teknologi dan Rekayasa

Invesment Casting Process Investment is dried [by] through heating from 100-110oC Cupola melts through mold material pore Chamber is formed as according to form of product wanted Heating is continued [by] until 1000C to harden the mold Teknologi dan Rekayasa

Invesment Casting Process Pouring of metal fluid into mold Mold disassembly Teknologi dan Rekayasa

Invesment Casting Product Example Teknologi dan Rekayasa
