The definition of mold and die in machinery
What Difference Between Molding(Moulding) And Die?
Molds (or moulds) and dies are used to make a variety of objects with many different media. For instance, plastic plumbing pipes can be made in a mold; tools such as wrenches are cast in dies. Molds tend to be used to produce products that need to be hollow in the middle, whereas dies are used to stamp solid products out of media such as steel. We'll introduce you to the definition, processing, and mold types.
Mold(Mould)
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. 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 molds 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 several different molds, each creating a section of a complicated object. This is generally only used for larger and more valuable objects.
Die
Dies are used to cutting objects from media; a cookie cutter is a very simple form of a die. Dies are useful because they can cut many objects at once, increasing productivity. Fancy edged papers are cut by dies, as are machine parts such as washers. Street signs are also cut with dies. The main idea behind dies is that they are used to create other shapes, and two dies can be used at the same time to create complex shapes.
Molding(Moulding)
Molding or moulding (see spelling differences) 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.
Die Casting
Tools and toys are often made with the die casting process. Molten metal is poured or injected into dies and allowed to cool. The die is then removed, and the product is ready for finishing. Die casting is a relatively fast process, which allows for faster production. It is not as refined as the molding process, and die-cast objects may not be as strong as products made with an injected mold.
MOULD is a container that you pour sift liquid or substance into which then becomes solid in the same shape as the container e.g. when it is cooled or cooked. A clay mold is used for casting bronze statues.

Mold types
- Liquid Moulds
Molds help manufacture things like doorknobs. There are two halves to a mold; this allows a great deal of detail to go into the center of the mold. A liquid medium is poured or injected into a premade mold; once the liquid is injected or poured in, it is allowed to cool and the mold is removed. The result is a single component that may in itself be the end product, or it can be made to have other things attached to it. - Solid Moulds
Solid molds are used to shape pieces of media. The medium is heated and formed into whatever shape the mold is. For instance, makeup artists may use a sheet of plastic and a mold to give added dimension to an actor's costume; this is especially useful if they are making something that does not exist in real life. If they need to make an actor a mask, for example, they would design the mold, put in a piece of flat plastic, and then press the plastic into place around the mold. This process takes a lot of pressure that has to be carefully monitored to keep the plastic from getting too thin or too hot.
Die types
- Cutting Dies:
These dies are used to cut the metal. They utilize cutting or shearing action. The common cutting dies are: blanking dies, perforating dies, notching dies, trimming, shaving and nibbling dies. - Forming Dies:
These dies to change the appearance of the blank without removing any stock. These dies include bending, drawing and squeezing dies, etc.

To sum up, a mold is a hollow form or matrix for giving a particular shape to something in a molten or plastic state. Die is any of various devices for cutting or forming material in a press or a stamping or forging machine. In the process, die casting is a relatively fast process, it is not as refined as the molding process.

WHAT IS HIGH-PRESSURE DIE CASTING?The term injection molding refers to the production of plastic parts while die casting involves production in metals. Die casting is most suited to softer alloys. In the past, tin and lead were popular materials for the die-cast parts. Today, zinc, aluminum, and magnesium-based alloys are the most common. High-strength structural automotive and aerospace components are produced, as well as many consumer goods...
