1.  high-quality refining and degassing blank outside the furnace

2.  imported gun drilling and multi-station group drilling, the mold hole is formed at one time, the finish is high, the production feed appearance is beautiful, the output is high, the discharge is smooth, and the granules are well formed

3. The mold adopts the combined treatment process of the American vacuum furnace and the continuous quenching furnace, which is quenched uniformly, the surface finish is good, the hardness is high, and the service life is doubled.

1.How to use ring dies and rollers correctly?
  Before the installation of the press roll, the sundries in the assembly hole shall be carefully cleaned and greased. The large side of the left roll shall face up to the right, and the large side of the right roll shall face down to the left. The press plate shall be installed in the hole.

2.What if the size of ring die is not suitable?
 The roller die clearance is adjusted by turning the eccentric shaft anticlockwise to make the clearance smaller and clockwise to make it larger.

3.How can operation delay the service life?
 The new ring die shall be equipped with a new press roll with a clearance of about 0.2mm and a normal production time clearance of 0.3mm. The adjustment of the roll die gap is very important. The gap is too small, the roll die directly contacts, the wear is increased, and the horn hole edge is damaged by rolling; If the clearance is too large, the output will be affected, and the machine is easy to be blocked, or even cannot be granulated. The experience shared by the old master is that when the ring die is turned by hand, it is better for the pressure roller to turn passively.
