ELEMENTARY COMPETENCY 2

2. Pouring Process
Pouring process ( casting) is impregnation of mold cavity with casting material which has been melted ( liquefied)

3. 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

4. 3 Kinds of centrifugal casting :
Vertical Centrifugal casting
Horizontal Centrifugal casting
Semi centrifugal casting
Teknologi dan Rekayasa

5. 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

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

9. 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

10. 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.

11. 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

13. 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)

14. 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

15. 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

16. Invesment Casting Process
Investment is dried [by] through heating from oC
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
