Teknologi dan Rekayasa 4 CASTING

Teknologi dan Rekayasa 5 Casting is a pour liqiud material process (steell or plastic) in the cast to make machine component CASTING Liquid steel pour to cast

Teknologi dan Rekayasa 6 CASTING PROCESS expandableNonexpandable

Teknologi dan Rekayasa 7 MAKING MANUAL CAST Casting product Workpiece dimensions that will be made in order to cover the print with sand print ready casting process

Teknologi dan Rekayasa 8 SAND CAST MANUFACTURING A. GRINDER SAND B. MIXING SAND C. SIFTING D. SEPARATION MAGNETIC E. SAND COOLIN

Teknologi dan Rekayasa 9 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

Teknologi dan Rekayasa 10 SAND CASTING The casting sand molds

Teknologi dan Rekayasa 11 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.

Teknologi dan Rekayasa 12 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

Teknologi dan Rekayasa 13 CENTRIFUGAL CASTING Centrifugal casting forming their own power using sand molds are played with constant velocity water turbine casting products

Teknologi dan Rekayasa 14 DIE CASTING Die casting is a metal printing process using a very high emphasis on low temperature Die casting One of die casting products

Teknologi dan Rekayasa 15 VELOCITY COOLING Speed in the cooling property affecting cast, quality and microstructure. Cooling speed is controlled by the print media.

Teknologi dan Rekayasa 16 KNOWING MACHINE PROCESS

Teknologi dan Rekayasa 17 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

Teknologi dan Rekayasa 18 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

Teknologi dan Rekayasa 19 CHIPS FORMATION The types and forms of chips process machining at the time began to take shape

Teknologi dan Rekayasa 20 Some forms of machining processes chips results CHIPS FORMATION

Teknologi dan Rekayasa 21 CHIPS FORMATION Formation of two-dimensional chips

Teknologi dan Rekayasa 22 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

Teknologi dan Rekayasa 23 CHIPS FORMATION Schematic drawings of chips formation analogous to the shift of a deck of cards

Teknologi dan Rekayasa 24 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.
