In recent years, driven by the upgrading of global high-end manufacturing industry, the market demand for high-precision industrial ceramic components has increased rapidly. Industrial ceramics have the advantages of high temperature resistance, corrosion resistance, high hardness and insulation, and are widely used in aerospace structural parts, new energy vehicle core components, semiconductor electronic accessories and medical precision equipment. Different from ordinary civil ceramics, high-end industrial ceramics have extremely high requirements for dimensional precision, surface finish and internal density uniformity, and the sintering forming process is extremely strict, which puts forward high-standard requirements for supporting graphite molds.
Graphite molds have become the preferred mold materials for high-end industrial ceramic sintering by virtue of their excellent high-temperature resistance, small thermal expansion coefficient, good thermal conductivity and easy processing characteristics. In the high-temperature sintering process of ceramics, metal molds are easy to deform and oxidize, and non-metal molds have poor thermal conductivity and low forming efficiency, while graphite molds can maintain stable dimensional accuracy under high-temperature working conditions, ensure uniform heating of ceramic blanks, and effectively improve the yield and precision of ceramic products. With the continuous expansion of the high-end industrial ceramic market, the global demand for special high-temperature resistant graphite molds has maintained rapid growth.
High-end ceramic special graphite molds have strict technical requirements. First, ultra-high dimensional stability is required, and the thermal expansion coefficient must be controlled within an ultra-low range to ensure no deformation during high-temperature sintering. Second, uniform internal structure is required to avoid local temperature difference leading to inconsistent ceramic product performance. Third, high surface finish is required to ensure the smoothness of ceramic product surface and reduce post-processing procedures. Fourth, excellent high-temperature oxidation resistance and fatigue resistance are required to extend the repeated use cycle of molds and reduce the production cost of ceramic enterprises.
At present, the global high-end ceramic graphite mold market is in short supply. Most graphite manufacturers can only produce ordinary industrial graphite products, and lack professional technical accumulation in high-precision mold processing and high-stability material modification. The poor batch consistency and low precision of ordinary graphite molds will lead to low yield of ceramic products and high production costs for downstream enterprises. Many overseas high-end ceramic manufacturing enterprises face the problem of insufficient supply of high-quality special graphite molds, which restricts the expansion of product capacity.
