Factory Direct Sale Customized Carbon Graphite Mold for Diamond Tools

Product Description

Graphite molds are important application tools in the manufacture of diamond tools (such as cutting discs and drill bits). They are irreplaceable due to their unique properties. Most diamond tools are formed by high-temperature sintering. Graphite molds are resistant to high temperatures of up to 3000°C, and they hardly expand or deform at high temperatures. They can also accurately maintain the size of the mold cavity, thus avoiding product cracking or dimensional deviation caused by thermal expansion and contraction. The excellent thermal conductivity of graphite molds enables them to quickly transfer heat during the sintering process, so that the diamond particles and metal binders are evenly heated, reducing internal stress and improving tool hardness and wear resistance. Graphite materials are easy to process and can be precisely engraved to produce complex structures such as fine tooth patterns and special-shaped holes required for diamond tools at the lowest cost. They are especially suitable for manufacturing ultra-thin cutting discs or micro drill bits. In addition, graphite molds are self-lubricated, and diamond tools are easy to demold after sintering without the need for additional coatings. At the same time, graphite molds are resistant to metal solution erosion and can be used repeatedly many times, with a cost much lower than molds made of other materials. In short, graphite molds, with their characteristics of "high temperature resistance, fast heat conduction and high precision", have become the core driving force for the efficient mass production of diamond tools.
