Molded Plastic Yo-Yo
A molder of plastic yo-yos wanted to introduce a higher quality product to the market. By incorporating threaded Brass Inserts into each half of the yo-yo, a higher quality joint would be created resulting in a truer rotational axis. Inserts also provide reusable threads which would enable unlimited assembly and disassembly without damage to the plastic. The molder wanted to utilize existing molds, as well as minimize the investment required to install the Inserts. The high heat and limited space made manual loading of the Insert into the mold undesirable. There was also the potential for a mis-loaded Insert to cause costly damage to the mold.
