Introduction

Die casting is the Metal forming process in whmolten metal is forced into a cavity or mold uhigh pressure. This takes place under highpressure which is applied to the molten metal

which is inserted into mold cavity.

Die casting is an ecient, economical processoering a broader range of shapes and

components than any other manufacturingtechnique.

Process Die casting provides comple shapes within close

tolerances than many other mass productionprocesses. !ittle or no machining is required andthousands of identical castings can be produced badditional tooling is required.

Die casting is one of the most versatile and proli"metalworking processes, creating countless varieof parts used in almost every industry imaginable

#nterestingly enough, it dates back to the mid $%&and today, innovations keep it moving forward.

The Hot Chamber Die CastinProcess

(ot chamber die castingis one of the two

main techniques in the manufacturing

process of die casting, (ot chamber die

casting has the advantage of a very highrate

of productivity. During industrial

manufacture by this process one of the

disadvantages is that the setup requires that

critical parts of the mechanical apparatus,

)such as the plunger*, must be continuously

submersed in molten material.

The Vacuum Die CastingProcess

+acuum casting creates good

conditions for decisively reducinggas

porosity, since air is evacuated fromthe

die cavity. Depending on the alloyused,

the required values may beachieved in

vacuum casting even without

additional

heat treatment. ut if such

The Low Pressure Die CastinProcess

!ow pressure die casting is competitive casting methowhen the production quantity is relatively small and0owhen heat treatment is needed to improve the mechaproperties. The tolerances and the surface "nish are tsame as achieved by gravity die casting. The tooling c

are somewhat higher than by sand casting.

What Are The Benefts o DieCasting

The bene"ts of using die casting over other methods of part

production are numerous. Die casting provides cost1eective

solutions to create parts that have comple shapes, parts that

a high heat tolerance, and also allows us to produce a part with

tighter and stricter tolerances. Die casting historically has inhe

produced less scrap and requires less machining than machininparts our of raw billets. 2hen compared with forgings, plastic

in3ections, stampings, etc, die casting is the clear choice for su

part quality with a low cost. Die casting produces partecellent

strength to weight ratios and allows for many dierent "nishing

capabilities.
