4. 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

6. 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

8. Molding sand Processing
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.

9. 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.

10. Molding sand Processing
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.

12. 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

13. 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

18. Bench Work
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
