Producing the seamless plastic ball
Equipment
Josef Novy Asked 10 years ago
Anyone has the idea how seamless balls like XuShaofa SEAMLESS Ball are produced ? If balls have seam it is simple but without a seam?

Hi Josef,
I am not sure. Perhaps someone can help us out here.

Make sure you buy a table tennis bat that is suitable for your level and allows you to develop your technique. For your first bat we recommend the PingSkills Rook, and when you upgrade to a custom bat we recommend the PingSkills Touch with Mark V or Rakza 7.

Hello Josef,
I just watched a video on YouTube about how they make there ball's. In the first few seconds you see where they take a wafer and put it in this tool. The wafer starts to rap around the metal ball in the tool and it looks like they are using heat. But after that few seconds the video goes into how they make balls with seems. Oh Yea, the video is from Nittaku. There is one thing of interest that I was reading about. That all 3 polyball manufacturers (DHS, Nittaku, and Xu Shafa) are in some type of patient infringement dispute over how the seamless balls are made.
Just thought this might be of interest to ya,all.;-)

that is interesting video. I could imagine something like this for production with seam but seamless balls remains mystery to me. Probably the balls are only seamingly seamless :-)
