Detailed size of the ceramic rod for your reference:
Since most of our products are custom-made, if the existing products do not meet your expectations, please provide relevant drawings and requirements, we can arrange the open mold production.
We mainly produce alumina ceramics, zirconia ceramics,and other ceramics.(If you dont know much baout the characteristics of material you can check the following form.)
