FAQ
Q: How long do graphite sintering plates last?
A: Service life depends on temperature, atmosphere, loading, and thermal cycling. In controlled atmosphere or vacuum sintering furnaces, graphite plates typically last 6-24 months with proper handling. Regular inspection and rotation of plates will maximize service life.
Q: Can you machine custom pockets and holes in graphite blocks?
A: Yes, we offer full CNC machining services for graphite blocks and plates. We can machine custom pockets, holes, grooves, and special shapes to hold your specific products during sintering. Please provide your drawings or product specifications.
Q: What grade of graphite do you recommend for sintering furnaces?
A: For most sintering applications, molded or extruded graphite blocks provide a cost-effective solution. For high purity requirements or very high temperature applications, isostatic graphite is recommended. Our technical team can help you select the optimal grade based on your process requirements.
