Manufacturing Process-Hot Press Forming

PPR Tee hot pressing is to flatten a tube blank larger than the diameter of the tee to the size of the diameter of the tee. The cold-drawn tee opens a hole in the stretched branch tube; the tube blank is heated and placed in the forming die. A punching die for stretching the branch pipe is installed in the tube blank; the tube blank is radially compressed under the action of pressure. During the radial compression, the metal flows in the direction of the branch tube and forms a branch tube under the stretching of the punching die. The whole process is formed by the radial compression of the tube blank and the stretching process of the branch pipe. Different from the hydraulic bulging tee, the metal of the hot-pressed tee branch is compensated by the radial movement of the tube blank, so it is also called the radial compensation process.
