C-frame presses are a commonly used type of hydraulic press. These presses get their name from the fact that the press itself is shaped like the letter “C”, however the press may be referred to by other names such as “gap-frame press”. C-frame presses are designed to take up less floor space than other metalworking machinery, while still providing great utility and minimal stroke deflection. Just like other hydraulic presses, C-frame presses are extremely versatile and can be used for many applications across several different industries.
While there may be some variations in C-frame press design, the general design consists of steel framework, hydraulic cylinder, and upper and lower platens. These are otherwise known as the slide table and the bolster table. The frame of the press is generally made from A36 steel because of its favorable characteristics and strength and makes our hydraulic C-frame presses suitable for stamping applications.
With the C-frame’s three open sides, the press can easily handle a variety of applications that include many material shapes and sizes. C-frame presses are often relied upon for applications that require smaller bed sizes and lower tonnages – although there are some exceptions. MULTIPRESS’ sister company, Pacific Press, for example has built C-frame presses with more than 750 tons of pressure for special applications.
While there can be design variations, all MULTIPRESS machines are designed to operate either manually OR automatically, to allow for the option of short run, or high volume production. In general, C-frame presses can also be fitted with a variety of different tooling to allow for bending, punching, cutting or straightening applications.
In addition to the open space made inherently available by its design, and the option to operate manually or automatically, C-frame presses offer manufacturers a variety of other benefits, including:
As mentioned, C-frame presses can accommodate a variety of applications. One of the more common applications is stamping. During the stamping process, stamped parts from the C-frame press are formed using a sheet metal such as copper, titanium, stainless steel, or aluminum. A press tool, referred to as a die, is used to shape the parts from the inserted sheet metal. The ram then pushes the sheet metal through the die creating the required shape.
Besides stamping, manufacturers may also perform other metal forming processes, such as:
Among the most common hydraulic press applications for MULTIPRESS are assembly, stamping and trimming.
Some of the industries that commonly rely on C-frame hydraulic presses include aerospace manufacturing, appliance, automotive manufacturing, ceramics, food and beverage processing, industrial, marine, medical, military and defense, packaging, and pulp and paper.
