Product Q&A

Q:What is the difference between single-ring and double-ring graphite crucibles? How should I choose between them?

The key difference lies in the number of rings at the rim and the bottom structure. A single-ring crucible has only one reinforcing ring at the rim and no ring at the bottom. Since the outer wall comes into more direct contact with the heat source, it heats up quickly and offers high thermal efficiency, making it suitable for induction furnaces and casting operations that require frequent loading and unloading. A double-ring crucible has one ring at the rim and one at the bottom; the bottom ring

Q:Can beginners use this crucible right away? Is it difficult to operate?

It is perfectly suitable for beginners. The product features a user-friendly single-ring clamping design that is easy to use and highly safe, requiring no complex technical skills. It is suitable for a wide range of users, including professional craftsmen, factory workers, DIY enthusiasts, and beginners, and is extremely easy to get started with.

Q:What is the lifespan of the crucible? Is it prone to cracking or damage?

The product is made of high-density graphite in a single-piece construction, offering resistance to thermal shock, wear, and thermal cycling. When used properly and avoiding severe impacts, it can be reused multiple times without cracking, warping, or breaking. Its service life far exceeds that of ordinary, low-quality crucibles.

Q:Do you offer customization for special sizes or shapes?

Yes, we have a professional mold development team that supports OEM/ODM customization based on customer-provided drawings or samples, including special wall thicknesses, heights, or irregular shapes.
