2021-10-25

Hot pressing is the process to make the diamond segment layers into a whole solid. Diamond segment layers are put into hot pressing machine which will make diamond segment layers into a whole solid under the high pressure and high temperature. It is a very important step, because different pressures and temperatures make different qualities of diamond segment.

After the hot pressing, we need to cold the mould and then take the diamond segment out from the mould. The diamond tips are almost ready in this step, waiting for surface treatment.Surface treatment will be done by sand blasting machine, which will clean the metal burr and made the surface of the diamond segment smooth and neat. Special surface requirements can also be met in Dialead, like opening the diamond, mark the direction and etc.
