Top Graphite Products For High-Performance Applications

The graphite boat itself is a kind of carrier, which can put the raw materials and parts that we need to position or shape together in it for high-temperature sintering. The graphite boat is made of artificial graphite through mechanical processing. So it is sometimes called a graphite boat, and sometimes it is called a graphite boat.

Graphite ingot molds are critical tooling used in the refining and casting of precious and non-ferrous metals to contain molten metal and cool it into standard ingots or bars.
Jiangxi Ningheda New Material Co., Ltd. manufactures these molds using isostatic-grade fine-particle graphite such as NX604 and NX605, with a bulk density of ≥1.85 g/cm³ and a compressive strength of ≥70 MPa. They feature rapid heat conduction, thermal shock resistance, non-stick properties, and do not contaminate the metal.
The channel dimensions can be machined into rectangular, circular, or elongated shapes, making them suitable for ingot casting of metals such as gold, silver, copper, and aluminum. The inner walls of the molds are smooth, ensuring smooth demolding and no metal contamination, and they are reusable, making them an ideal choice for jewelry casting, precious metal recycling, and laboratory smelting.
We support customization of various structures, including single-channel, multi-channel, and cover-plate designs, to accommodate the casting production of metal ingots of different sizes and weights.

The graphite casting crucible with a center hole is a high-end graphite product developed by Ningheda New Materials specifically for the precision metal melting and casting industry. Unlike traditional open-top crucibles, this product features a precision-machined tapered neck design at the top with a central positioning nozzle hole, enabling directed, splash-free pouring of molten metal. It is particularly suitable for use in jewelry vacuum casting machines, laboratories, research institutions, and small-batch precision casting of non-ferrous metals.

Our graphite molds are made from high-quality graphite raw materials featuring an ultra-fine grain structure, high purity, and high graphitization degree. They are precision-machined using CNC technology and are widely used in the hot-press sintering processes for diamond tools such as diamond cutting heads, diamond saw blades, diamond wire saw beads, and diamond grinding heads.

In the manufacturing of diamond tools, graphite molds serve a dual role as both heating elements and mold supports; their quality directly determines the dimensional accuracy, surface finish, and ultimate performance of the diamond tools. With a rigorous quality control system and advanced machining equipment, Ningheda ensures that every set of graphite molds maintains excellent dimensional stability and durability under high-temperature, high-pressure sintering conditions, with an average service life of 30 to 40 sintering cycles.

Fine grain graphite block produced by cold molding are widely used in machinery, electronics, semiconductors, polycrystalline silicon, monocrystalline silicon, metallurgy, chemical, textile, electric furnaces, space technology and biological and chemical industries
