HAMMER FORGING
Sistas uses high quality carbon and alloy steel forged components on the air driven hammers for a multitude of industries. With an emphasis on quality, the customers requiring product from this process have short lead-time needs for low volume, market developed products. Hammer Forging is the preferred method for low volume individual forgings. Sistas has hammers ranging from 20 kg up to 110 kg with 7 hammer forging lines. The process is done with a ram, delivering intermittent blows to the section to be forged, applying tremendous pressure, shaping the material, by an instantaneous application of pressure to a relatively small area. The hammer is forced from its maximum height, by air pressure. Large and small forgings, producing an infinite variety of shapes and sizes, are forged using our power hammers, providing maximum flexibility for you at Sistas Forge. Hammer forgings can also create a high degree of grain refinement
PRESS FORGINGS
Press forgings are produced in a broad range of sizes at Sistas Forge. With the increased use of technology and consistency, the process provides customers the necessary improved precision they need. These presses help the customers get their larger economic quantities, while also helping them cut the costs on these parts with continuously improved performance. Sistas has both 250 ton and 2, 500 ton press capability. This process is where a slow continuous pressure is applied to the area to be forged. Press Forging can be more economical than hammer forging (except when dealing with low production numbers), and close tolerances can be obtained. This method can also be used to produce both symmetrical and asymmetrical parts from carbon, alloy and stainless steels. This is a volume solution to the customers’ needs, and at Sistas Forge it is possible to meet the most demanding requirements with the press capabilities.
