HI-Tech Carbon Co.,limited
Diamond Sintering Graphite Mold
1.The diamond saw sintering mold.
2.Diamond drill sintering mold (integral, modular, fan-shaped teeth, straight teeth).
3.The shaped graphite mold series.
Hot pressure sintering involves heating of diamond segments under pressure with help of graphite mold.
we offer wide variety of graphite grades combining properties like hardness, resistivity and flexural
strength for this application. We offer complete machined molds made to customer specifications
Could be any sizes according to customers' drawings or requirements
