Polycrystalline module should be noticed in the drawing process:

A. a full set of polycrystal drawing die after continuous work full 600 hours should be timely discharged all mold polishing repair, remove mold compression area in the ring groove, increase the service life of the die, if used without timely polishing treatment, which will greatly shorten the mold of the whole service life, some even large size of die cracking cannot be used normally

B. the first in line mode, in order to avoid wire from Actinomyces frame into the first polycrystalline module of mould produce jitter impact and affect the impact of inner hole die polycrystalline polycrystalline, wearing the first into the mold line in front of this mold increased a tungsten steel die, its purpose is in order to put the wire into the polycrystalline module is poised to enter the general.

In the full set of polycrystalline die mold material usually in addition to the finished mold imports polycrystalline module and imports polycrystalline module to better ensure the copper wire size stability and the rest of the full use of domestic polycrystalline module, because imports polycrystalline module the cost must be higher than domestic polycrystalline.
