SAND MOLDED CASTING, ALSO KNOWN AS SAND CASTING, IS THE MOST WIDELY USED METAL CASTING PROCESS. THE PROCESS USES TEMPORARY, NON-REUSABLE SAND

MOLDS TO FORM METAL OBJECTS.

WHAT IS SAND CASTING?

CHALLENGES IN PATTERN MAKINGFOR SAND CASTINGPRODUCTIVITY » Labor intensive

» Long pattern production time

COST » High cost of production» High cost of error

COMPLEXITY » Difficulty to produce complicatedpatterns using conventional methods

BENEFITS OF 3D PRINTINGMARKET POSITION

Conquer new customersegments and expand

customer base

COST

Significantly lowerproduction cost

SPEED

Reduce patternproduction time

ADDED VALUE

Freedom to conductexperiments with

many different designsand multiple iterations

LIGHTS OUT PRODUCTION

Run the machinewithout supervisionovernight and over

the weekend

TIGHTEN CONTROL

Control thewhole process of

manufacturing thepatterns IN-HOUSE

PATTERN MAKINGA replica of the object is made using wood,metal, plastics and other materials.

MOLD - MAKINGSand mold is formed by packing sand around thepattern. When the pattern is removed, a hollow shapeor cavity, forms the casting.

COOLINGThe mold cavity is then cooled and hardenedat room temperature.

CASTINGMolten metal is poured into the mold.

REMOVALThe solidified part (casting) is ejected, orbroken out of the mold.
