PPM is the series of sturdy, reliable and efficient Faccin hydraulic dishing presses for mass production of dished ends or plate forming in general. The PPM designed and built by Faccin are hydraulic presses suited to dished head crowning, featuring an exclusive design with the top and bottom beam connected by two uprights. The portal frame is connected by two hydraulic protensioned tie-rods that guarantee the maximum resistance and elasticity to the structure in order to resist fatigue. Thanks to the exclusive HPT system utilising two solid forged tie rods (permanently preloaded) to keep the frame connected, a PPM dishing press is able to minimise frame deformation, guaranteeing longer life and reliability.
Faccin can also offer cheaper solutions to manufacture dished heads and tanks. In these lines for dished heads, the frame is connected to the upper beam with keys machined on the structure or just welded to the structure in single monolithic pieces.
The presses are equipped with a set of dies of various radii in order to form different sizes and types of dished ends. The material and the shape of the dies is the result of Faccin’s more than 40 years of experience in manufacturing such machines.
The dishing process is a rather slow process where the plate is pressed several times between the dies. A good dishing press must be fast and this is why the Faccin PPM dishing presses are equipped with an advanced hydraulic system capable of guaranteeing the fastest movement of the main cylinder, which means minimal dishing time.
The PPM Hydraulic Dishing Presses are available in various sizes: to choose the exact size, you need to calculate the dimension of the largest development of the metal plate to be processed, then you may decide the distance between the uprights. An important feature of the press is the force available, which normally determines the ideal range of thickness.
Faccin manufactures presses from 150 tons of force up to more than 3,000 tons, covering all the needs of the market.
Faccin also offers effective handling systems designed to allow for accurate positioning of the plate under the dies of the hydraulic dishing presses. Faccin’s automatic manipulators in the MA range assure high quality and offer several advantages. By using the automatic manipulators for dished heads, it is possible to optimise production, saving time and processing several plates at once.
The PPM dishing presses, together with the automatic manipulator, can be handled with a numerical control that manages all the movements synchronized. It is also capable of handling completely automatic dishing cycles.
