Graphite sputtering targets are made from high-purity graphite material and come in a variety of shapes and sizes, such as discs, rectangular tiles and custom shapes. Graphite sputtering targets are very durable and provide consistent, high quality films in the PVD process. They offer excellent thermal and electrical conductivity, good adhesion to the substrate, and high hardness for use in high-temperature, high-pressure environments.

Graphite jewelry molds make original designs of graphite crucibles attached to them for a long time, which keeps high-temperature resistance. Making graphite molds for jewelry is the procedure used to insure that jewelry items can be accurately duplicated at any time future. The mold making process begins with the creation of a metal model. Models can be as simple as a basic ring or complex as jewelry containing multiple interlinking parts used to create elaborate multicolor jewelry. What's the difference between graphite ring molds and metal ring molds? Custom graphite molds for glass, while less costly and more resistant to warping under high temperatures compared to metal counterparts, may impart a slightly rougher finish to the glass ring. This difference in finish arises from the inherent properties of the materials; graphite tends to have a slightly coarser texture than metal. However, graphite molds excel in thermal stability and are often preferred for their durability and longevity in glassmaking processes. Conversely, metal ring molds, such as silver casting molds, offer a smoother finish but come with a higher price tag and susceptibility to deformation under extreme heat. Glass artisans weigh these factors when selecting between graphite and metal ring molds, balancing cost, durability, and desired surface finish in their creative endeavors.
