Our company produces and sells reducers, which are a kind of pipe fittings. Its specifications are -, using a one-time molding process, and they are made of homopolymer polypropylene.
The production of seamless large and small heads:
The large and small heads (reducers) are a kind of pipe fittings used at the pipe diameter reduction. The commonly used forming processes are reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing. For certain specifications of reducers, stamping can also be used.
.Reducing/expanding forming
The reducing forming process of small and large heads is to put the tube blank with the same diameter as the big end of the big and small heads into the forming mold, and press it along the axial direction of the tube blank. The metal moves along the mold cavity and shrinks into shape. According to the size of the reducer, it is divided into one-time pressing forming or multiple pressing forming.
b. Stamping
In addition to using steel pipes as raw materials to produce large and small heads, some specifications of large and small heads can also be produced using steel plates using the stamping forming process. The shape of the punch used for stretching is designed with reference to the inner surface dimensions of the large and small heads, and the punch is used to punch and stretch the blanked steel plate into shape.
