Casting Process


Definition

Casting is a pouring process of liquid matter like metal or plastics packed into by mold, then is let freeze in the mold, and then is released or in breaking to be made machine component


Metal Casting Process



Casting usually is started with molding with sand material


Molding of hand with big dimension can apply hard soil mixture as binder


Manual Molding

Dimension work substance which will be made ( a), closes over equiamplitude surface of cupola for the agenda of print with sand, ( b) mold ready ( c),

pouring process ( d), and casting product ( e).


Sand breaker

Sand sand is applied if the sand apply Clay as binder, while for sand agitator is applied if sand to apply binding material like drier oil or silicate sodium.

Sand blender

Sand blender applied to break sand lumps after blending. So, sand from sand breaker sometime is filled in to sand blender or usually ex sand filled in direct to depth.

Molding sand Processing


Screening

To get molding sand, screen used to cast aside impurity and grain a real rugged sand. Screen type there are two kinds, that is rotary screen and vibrant screen.

Magnetic segregation

Magnetic segregation applied to cast aside potonganpotongan iron staying in the molding sand.



Sand coolant

In making cool sand, coolant atmosphere need to come into contact with grain sand as many as possible. At sand coolant pengagitasi, atmosphere through sand agitated.

As for at erect sand coolant, sand is dropped into tank and disseminated by a blade during shoot, which then made cool by atmosphere from under.



Casting With Sand

Metal casting at sand casting


Casting With Gips

Casting with gypsum much the same to with casting with except to sand part of gypsum is changed with sand.

Durable gypsum of a more regular is applied as component of basis in produce of touch pitch copper basrelief or as chisel blade at stonecutter process


Centrifugal Casting

Centrifugal casting differs from pouring of free gravitation and free stress because centrifugal casting forms self energy power applies sand casting turned around with constant speed


Die Casting

Die casting is processing metal printing by using a real emphasis height at low temperature


Forming Process


Formation of Plate

Formation of plate from slab becomes form of box or cup by using dividing valve and mold.

Formation of this plate earns also bends from material


Formation of plate result

Formation of Plate


Bench work is work of produce of component or device using work table. Example making component to apply devices like ragum, hammer, file, hand boring, grinder, and others bench work device.

Usually this devices applied to make simple work substance and level of precision that is is not is height

Machining Process


Definition

Machining process applies appliance engine which in the form:

Process lathes ( turning)

Hobbing process ( milling)

Lathe CNC


Turning Process

This engine in principle is rotary work substance is cut to to become component wanted in the form of cylinder or taper.

This engine can only make substances which is in the form of cylinder

Milling Process

Milling Machine in principle tool or rotary chisel lessens work substance dimension.

This engine also earns to refine equiamplitude surface, makes path, gear, and other form wanted down alley engine

CNC Machine

Mechanically CNC ( Computer Numerical Control) produce of acceleratable component and more accurate. this CNC Engine used mass production to.

This engine requires operator having specialty drawn up to implement engine CNC
