Molding

Molding or moulding is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object.

A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material.The liquid hardens or sets inside the mold, adopting its shape. A mold is the counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated moulds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs.Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for larger and more valuable objects.

Molding designing in SolidWorks

On this video below i try show the way i pass when i was designing molding in SolidWorks. Before i putting in real things.

After design the mold by using software design like solidWorks i try to make 3D Roughing in Vcalve and shopBot in order to complete my assignment.

3D Roughing

Rough Machining is used when carving 3D parts to clear away excess material when the part is too deep for the finishing tool to cut in a single pass.

these images below will show the all steps i pass. when i was using Vcarve in to generate shopbot file.

More info on 3D roughing here

This video below show the way of toolpath it will pass by using Vcalve software editor in to generate the shopbot file.

After finishing designing and 3D roughing i try combine two part,i rough by using glue in order to make full molding. And also i need to make a hole in my part in order to see where the casting material it will pass in easy way.

After all of this i putting a glue on the part in to combine my all part.

Now i finish moldig i am going to apply casting.

Casting

Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.

Now i am going to start to casting. Before i start i take that molding staff i made. and then i putting inside in the hole the component A&B for casting after while i waitting to dry and then remove my solidy.Actually casting it done

First you need to mix this component A and B 50 by 50 of volume and then mix it both A and B in one container.

After mixing it both compont A abd B you need to put the things you have mix in your mold, you have made in order to fill the all empty space along on your mold design.

the following picture will it show all.

After all of this you can wait like an hour for dry. the following picture it show how it looks like after dry.

After dry you need to break you mold in order to remove the things you have made.

Now this is the official assignment. Means maolding and casting Done well.
