The lifespan of electronic graphite molds depends on graphite grade, machining tolerance, surface treatment and operating conditions. Oxidation is the main failure cause. Graphite gradually wears under high temperature with oxygen, leading to enlarged cavities and chipped edges, which causes out-of-spec electronic parts.
Key Properties
Optional anti-oxidation coating: SiC coating greatly improves oxidation resistance and extends cycle times.
Adjustable density: High-density graphite offers better wear resistance for high-volume production; medium-density graphite is cost-effective for sampling.
Repairable: Partial worn areas can be re-machined to cut replacement cost.
Multi-cavity design: Integrated multi-cavity structure boosts batch output for standardized electronic parts.
Applications
New energy electronic components, automotive semiconductors, RF devices, precision thick-film circuit sintering, powder metallurgy electronic magnetic core forming. Jiecheng Graphite supplies bare graphite molds and SiC coated versions with material certificates and fast drawing evaluation & sampling service.
