For a detailed design break down check out the Luftverk Blog Post!This is the Plastic Fulvia, an “Injection Machined” yoyo which is a technique that achieves that classic yoyojam over molded bearing seat feel but the quality of a premium machined aluminum. It is first injection molded into a large plastic blank then the profile is completely CNC machined. This is an independently funded project that I have dumped a monumental amount of money into, so it’s pretty surreal to see it completed! The R&D, prototyping and testing for this product has been so insane. I made a blog post about the complex manufacturing process, design struggles and the benefits of this manufacturing technology which can be found in the blog post.
