Seamless pipe is formed by forming process. Forming process may be defined as an extrusion process, normally performed at the end of semi-solid round to produces a larger cross-section. Extrusion process can be carried out cold or hot. In a given simulation of seamless pipe forming, cold extrusion process is used. The seamless pipe is normally done in the three steps but for ease of the simulation,
seamless pipe is made in a single step. Consider the various parameters of this simulation. The material of the billet is aluminium. The temperature of the billet is 20<sup>o</sup>C. In the simulation video the billet is divided into small finite element to have better analysis of the force. The hydraulic press is used for deformation. In the right hand top side of the simulation video
one can see the upper die or punch, the billet and lower die and seamless pipe. In the left hand bottom side of the video one can depict the variation of strain in the billet during the extrusion operation. Similarly in the right hand side we can see the extrusion process and arrangement of the die and billet.

The setup for turbine blade forging is as shown in the video. The yellow part is the plunger, the red part is the billet and the green part holds the blade cavity. During the process, the plunger pushes the billet from left hand side. The billet while moving inside the cavity deforms and takes the shape of the blade cavity inside the green die.
In the video, one could see the blue mesh of the blade being formed during the process of forging. One could visualize the mesh size changing which gives an idea about the forces acting on the billet.The finished blade is shown at the end of the video.

The video shows the manufacturing of golf stick using metal forming techniques. A typical golf consist of shaft and loft without any seam with a handle for grip. A die for extrusion of shaft of golf stick is shown in grey. A sectioned view of the die shows the threaded portion for handle grip.
In step one, a red billet is placed at the top of the cavity in green extrusion die. A yellow plunger presses the red billet shaft channel in extrusion die. It also has an accumulated portion for loft at the end of die. The billet progressing in the die can be seen and temperature of billet
can be determined by the scale on left side. After extrusion, forging of loft is done to have different club heads. The dies shown in green and yellow can have different cavities depending upon the club. After forging with dies the final loft section is shown at end of the video.
