Celcon and Delrin aren’t exactly the same plastic. Celcon is injection molded, where as Delrin is machined. Of course, injection molding is not as precise as machining, meaning that Delrin yoyos tend to be higher quality than their Celcon counterparts.

celcon and delrin are the exact same thing. They’re different brands of POM. Delrin can be injection molded, it’s just usually machined.

They are practically the same, but not exactly. Delrin is homopolymer while Celcon is copolymerized for easier injection molding. The reason for this is due to the dramatic shrinkage that homopolymer POM undergoes during injection molding. The copolymer version still shrinks like hell, though, just a bit more managable.
