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


11/25


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

VELOCITY COOLING

Speed in the cooling property affecting

cast, quality and microstructure.

Cooling speed is controlled by the print

media.

KNOWING MACHINE PROCESS


17/25


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

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)

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.
