CASTING


Casting is a pour liqiud material process (steell or plastic) in the cast to make machine component

CASTING

Liquid steel pour to cast


CASTING PROCESS

MAKING MANUAL CAST

Casting product

Workpiece dimensions that will be made

in order to cover the print with sand

SAND CAST MANUFACTURING

A. GRINDER SAND

B. MIXING SAND

C. SIFTING

D. SEPARATION MAGNETIC

E. SAND COOLIN


EKSPANDABLE (EXPANDABLE MOLD CASTING)

Expandable mold casting is a generic classification that involves sand, plastic,

shell, plaster, and molding investment (lost-wax technique).

This method involves the use of molds and mold as disposable


SAND CASTING

The casting sand molds


PLASTER CASTING

Casting with a cast almost the same as sand casting except in the plaster changed with sand.

Gypsum mixture consists essentially of 70-80% 20-30% gypsum and gypsum and water reinforcement.


CASTING PLASTER, CONCRETE, PLASTIC OR RESIN

Using the casting of concrete, not plaster casting, allows us to make a carving, fountain, or outdoor seating.

Next is to create a sink (washstands) is interesting, washstands and shower stalls with a diverse mix of colors will produce an interesting pattern as it appears on the marble / ravertine


CENTRIFUGAL CASTING

Centrifugal casting forming their own power using sand molds are played with constant velocity

water turbine casting products


DIE CASTING

Die casting is a metal printing process using a very high emphasis on low temperature

Die casting

One of die casting products


VELOCITY COOLING

Speed in the cooling property affecting cast, quality and microstructure.

Cooling speed is controlled by the print media.


KNOWING MACHINE PROCESS


Machining process is like a metal cutting process

• The process of cutting with a pressing machine• Conventional cutting process with machine tools • Unconventional cutting process.

Cutting process using pressing machine: the cutting (shearing), pressing (pressing) and withdrawals (drawings, elongating).

Conventional cutting process with the process of machine tools including lathe (turning), the process frais (milling), and sekrap (shaping).

Unconventional cutting process for example by machine EDM (Electrical Discharge Machining) and wire cutting

MACHINE PROCESS


Some machining process: 1. Lathe (Turning / Lathe) 2. Frais (Milling) 3. Sekrap (Planning, Shaping) 4. Drill (Drilling) 5. Grinding (Grinding) 6. Drilling (Boring) 7. Pelubang (Punching Press) 8. Surface Grinding (Surface Grinding

MACHINE PROCESS


CHIPS FORMATION

The types and forms of chips process machining at the time began to take shape


Some forms of machining processes chips results

CHIPS FORMATION


CHIPS FORMATION

Formation of two-dimensional chips


CHIPS FORMATION

Cutting areas that described the current lines. When the workpiece material moves from one piece of material to the slide,

then cut off, and then became chips


CHIPS FORMATION

Schematic drawings of chips formation analogous to the shift of a deck of cards


HEAT PROCESSING

Rolling

Rolling Machine

Red-hot steel bars, transformed into useful products through the rolling

Forging

Forging hammer, forging stricken, upset forging, press forging, and forging rolls. One result of the process of refining the grain processing is caused by recrystallization.
