Our company offers mold-less solutions! Instead of using molds for prototypes of products planned for mass production, why not first create the main body of the prototype in glass? While there are exceptions, the delivery time is around one month, and the initial costs can be "significantly" reduced compared to ordering molds. Therefore, it is faster, cheaper, and easier to make revisions than ordering molds! This can also help verify drawings, such as confirming "the thickness was correct" or "the radius met expectations"! We can accommodate various processing techniques, including steps, recesses, mirror polishing, concave, convex, openings, and slits! If you're interested, please feel free to contact us.
