Manufacturing method of copper mould tube

1, Extrusion molding method

Use a suitable copper blank to deform the inner core and outer mold on the press first, and then perform the processing method of extrusion forming of the finished product.

In the production of square billet and rectangular billet copper mould tubes, the remarkable feature is uneven deformation. The greater the degree of uneven deformation, the greater the processing difficulty.Moreover, "orange peel" or pitted surface defects appeared on the inner surface of the pipe.

2, Explosive forming method

The huge impact energy released by the explosion of the explosive laid on the outer surface of the blank material is used to instantaneously load the tube blank. Make it get enough energy to accelerate the movement to the surface of the core mold, and when the tube blank material is completely attached to the core mold, its high-speed operation suddenly drops to zero. The tube blank is subjected to the reverse pressure of the core mold, and plastic flow occurs under the action of the three-way compressive stress, and the inner cavity of the tube blank forms a cavity that is exactly the same as the surface of the core mold.

Sometimes when working on the mould assembly, in order to ensure that the production is qualified, we need to identify the quality of the copper mould tube:

To observe the surface of the copper mould tube, you can try to use some sharp objects to gently scrape it , If it is a high-quality copper mould tube, a deep line can be scraped out very well.
