Forging is one of the common manufacturing processes, that shapes a metal piece by applying compressive forces on it.

Hot Forging VS. Cold Forging

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer often a power hammer or a die. Forging is often classified according to the temperature at which it is performed: cold forging a type of cold working , warm forging, or hot forging a type of hot working. For the latter two, the metal is heated , usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons. Since the Industrial Revolution , forged parts are widely used in mechanisms and machines wherever a component requires high strength ; such forgings usually require further processing such as machining to achieve a finished part. Today, forging is a major worldwide industry.

Forgings | The Difference Between Hot and Cold Forging

Hot and cold forging are two different metal forming processes. While they are performed at significantly different temperatures, they deliver similar results. Several factors are taken into account when deciding between hot and cold forging. When a piece of metal is hot forged, it is heated to extreme temperatures. The average temperatures necessary for hot forging are up to degrees Celsius for steel, to degrees Celsius for Al-Alloys , and to degrees Celsius for Cu-Alloys. This kind of extreme heat is necessary for avoiding strain hardening of the metal during deformation.

Forgings | The Difference Between Hot and Cold Forging

Forging is a manufacturing process that uses compressive forces to form metal into the desired shapes and sizes. Industry professionals employ a variety of different forging techniques—depending on the material and the product being forged—each of which carries its own advantages and best uses. The following blog provides an overview of the different types of forging methods available, outlining what they entail, their key advantages, and their typical applications.

Forging is the process of deforming metal into a predetermined shape using certain tools and equipment—deformation is accomplished using hot, cold, or even warm forging processes. Ultimately, the manufacturer will look at a number of criteria before choosing which type of forging is best for a particular application. Forging is used where the arrangement of the grain structure imparts directional properties to the part, aligning the grain so that it will resist the highest stress the part will encounter. Casting and machining, in comparison, usually have less control over the arrangement of grain structure.

Understanding the Different Forging Processes

Только туда ей и оставалось идти в наглухо запертом помещении. Поднявшись по ступенькам, она обнаружила, что дверь в кабинет шефа открыта, поскольку электронный замок без электропитания бесполезен. Она вошла. - Коммандер? - позвала Сьюзан.

Молодой программист приходил когда-то в Нуматек, тогда он только что окончил колледж и искал работу, но Нуматака ему отказал. В том, что этот парень был блестящим программистом, сомнений не возникало, но другие обстоятельства тогда казались более важными. Хотя Япония переживала глубокие перемены, Нуматака оставался человеком старой закалки и жил в соответствии с кодексом менбоко - честь и репутация.

 Садись, Сьюзан. Я должен тебе кое-что сказать.  - Она не пошевелилась.  - Когда я все закончу, я сообщу тебе код вызова лифта.

 Да, сэр. У нас все это записано на пленку, и если вы хотите… - Исчезает фильтр Х-одиннадцать! - послышался возглас техника.  - Червь преодолел уже половину пути. - Забудьте про пленку, - сказал Бринкерхофф.  - Вводите ключ и кончайте со всем .
