A direct double-action extrusion press includes a main crosshead to which an extrusion stem is fixed; a main cylinder having a main ram that advances the main crosshead and pressing on a billet; a piercer cylinder disposed inside the main ram and drives a mandrel; a plurality of side cylinders that retracts the main ram via the main crosshead; and a hydraulic circuit for supplying hydraulic oil to the main cylinder, the piercer cylinder, and the side cylinders. Cylinder chambers of the plurality of side cylinders on a side where the hydraulic oil is discharged when the main crosshead is advancing have a pressure-receiving area equal in total to that of a rod side chamber of the piercer cylinder. During billet extrusion, the hydraulic circuit causes fluid communication through the rod side chamber of the piercer cylinder and each cylinder chamber of the plurality of side cylinders on the side where the hydraulic oil is discharged.

A method of processing BMGs in a non-ideal environment (such as air) to create a uniform and smooth surface is provided. By utilizing the contact-line movement and an engineered flow pattern during TPF the method is able to create complex BMG parts that exhibit uniform smooth appearance or even can be atomically smooth. In addition, to mending surface imperfections, this method also eliminates void formation inside the material, allows for the creation of precise patterns of homogeneous appearance, and forms improved mechanical locks between different materials and a BMG.
