A press is a type of machine of which there are many kinds; however, in its most basic form a press is a machine that uses pressure in order to exert force upon an object. The three main types of pressure that presses utilize are mechanical, hydraulic and pneumatic pressure.
In addition to repair work, press repair service companies often provide rebuilding/remanufacturing, retrofitting and refurbishing services as well. Some examples of press problems that would require repair services include worn or broken cylinders and valves, worn seals and hoses, broken shaft and other damaged components such as through liners and wiper rings.
Essential to many applications, press repair companies offer a valuable service to industries such as: printing, in which the repair of worn or damaged printing presses is crucial; industrial, for the repair of presses such as hydraulic presses, C-frame presses and more that are vital to many manufacturing applications such as metal stampings; automotive, which utilizes presses in the manufacturing of numerous auto parts such as hubs, fenders and various body parts; and textile, which utilizes presses such as calendaring heat presses and letter printing presses.
Some of the most common types of presses that press repair service companies work with include stamping presses, brake presses and forging presses. An often used machine in the industrial manufacturing industry, stamping presses are defined as devices that are designed and built to operate one or multiple progressive stamping dies and other types of dies as well.
Stamping presses are such a popular type of press because they have the ability to fulfill almost any metal forming or stamping need. Brake presses, on the other hand, are defined as devices that are used to make bends or folds in sheet metal by means of pressing them into dies through a cold working process. Also known as press brakes, brake presses can be manually-operated, but are typically either semi-automatic or fully automatic.
Lastly, forging presses are also extremely common in the industrial manufacturing industry. Forging presses are defined as devices that are typically hydraulically-powered, and are a type of metal forming machinery that force metal blocks to take the shape of a product by means of a mold, extreme force and pressure, and sometimes heat. Forging presses are often used as an alternative to hammer and rolling forging, and by utilizing two press rams that move together in a linear motion, forging presses are able to produce up to 50 thousand tons of force at one time.
