Graphite Molding for Semiconductor Packaging: Applications in Lubrication Fields such as Plunger and Ball Valve Assemblies

Due to the high hardness and good lubricity of diamond-like coatings, they are well-applied in lubrication fields such as plungers, ball valve assemblies, bearings, sliding tracks, gears, ceramic valve pieces, piston rings, and driving components. Parts like plungers and nozzles require unchanged roundness after processing, hence the coating must be achieved during the low-temperature process. Components coated with diamond-like coatings can effectively meet wear resistance and oil-free lubrication needs without affecting dimensions.

Graphite Molding for Semiconductor Packaging: Applications of Graphite on Various Mold Surfaces

Diamond-like coatings offer high hardness, smooth surfaces, low friction coefficients, easy demolding, wear resistance, acid and alkali resistance, excellent thermal conductivity, and low-temperature processing capabilities. The material's high-pressure jetting and particle impact are difficult to damage it, making it far more suitable for mold protection than other materials, significantly increasing mold lifespan. The diamond-like coating applied to molds can protect precision areas (such as EDM machining surfaces), assist in heat dissipation, improve mold flow properties, enhance demolding, forming rate, and replication rate, shorten process time, improve product yield, and reduce the time and frequency of mold disassembly and cleaning. Generally suitable for applications in plastic injection molds (including precision and optical molds), plastic fiber-reinforced injection molds, powder metallurgy molds, glass forming molds, blow molding molds, and aluminum extrusion molds, etc.

Graphite Molding for Semiconductor Packaging: Applications in Extensibility Material Cutting Tools

Many metals or alloys with high extensibility tend to stick to cutting tools during machining, especially at high temperatures, leading to reaction with the tool and making processing difficult, as well as reducing tool life. Applying a diamond-like coating to such tools can solve the issue. Diamond-like coated tools are suitable for machining materials like copper alloys, aluminum-magnesium alloys, ceramics, tungsten carbide, lead alloys, and carbon-containing materials (graphite, plastics, and composites, rubber), etc. However, due to carbon atoms dissolving into ferrous materials, they are not suitable for processing materials containing iron, cobalt, nickel, and others.

Graphite Molding for Semiconductor Packaging: Applications in Optics, Packaging, and Computer Data Storage

Due to its exceptional density, diamond-like membrane is effective in component encapsulation, blocking moisture and oxygen. It also aids in component cooling, making it an excellent encapsulation material. When used in the encapsulation or cooling components of electronic and optoelectronic devices, it facilitates heat transfer, quickly dissipating heat generated during operation, thus extending the lifespan of the components. Moreover, its application in CDs and hard disks can prevent disc corrosion and avoid scratches.

Graphite Molding for Semiconductor Packaging: Applications in Gaging and Measuring Tools

Due to the excellent lubricating properties of diamond-like coatings, their application in measuring tools is quite extensive. They can reduce friction and extend the service life. For instance: calipers, gauges, plug gauges, and fixtures, etc.
