Hasenclever FPRN 250 screw press - description

Friction screw press Hasenclever FPRN 250 — 630 ton (ID:76467) is press equipment in which force is generated by screw rotation and converted into linear motion of the ram. This type of press is used for various bulk metal forming operations. The press combines high energy capacity with precise stroke control, which is especially important when stamping parts with tight tolerances.

Screw press Hasenclever - technological processes and operations

Forging The process of plastic deformation of metal, in which the workpiece changes shape under the impact of blows or static pressure. During forging, the metal structure is densified, internal inhomogeneities are eliminated, and the mechanical properties of the material are improved. As a result, forged products are distinguished by high strength and reliability when operating under significant loads. Forging is used both for producing finished parts and for preparing workpieces for subsequent stamping.
Closed-die forging The workpiece is deformed inside a die cavity that restricts metal flow, forcing it to fill the exact shape of the tool. Under high pressure, the material spreads into every recess and detail of the die, producing a part with precise geometry. This method provides high accuracy and repeatability, making it the standard for series and mass production of complex forgings.
Preforming Preforming prepares the workpiece for the main stamping operation by giving it an approximate shape of the future part. The metal is distributed in the die to facilitate final filling and reduce tool wear. This intermediate step improves accuracy and quality of the finished product.
Calibrating A finishing operation that brings the forging to precise dimensions. The workpiece is placed in a calibration die, where under pressure its surface is leveled and the geometry is brought to the specified tolerances. This process eliminates minor shape distortions left after previous operations. As a result, the part receives stable dimensions and a smooth surface without additional machining.
