I am working on a project that will require gluing up boxes made from MDF. They will have dados and rabbits, and as this will be a commercial, and on-going venture, speed in assembly will be critical. My first thought was standard yellow glue, with staples. However after working on a few prototypes I am thinking that isn't going to work. Also the customer would rather not have the staple holes visible when done. I can fill them of course but still that adds a step and cost. I tried using hot melt glue and that may work, especially if I get an industrial grade gun. Not cheap at close to $1000 but as a one time investment for what should be years of revenue, well worth it.
Any other suggestions? I know there are many options out there but I have little experience with this area. The final products needs to be strong, relatively speaking, as the product is 100% MDF.
Thanks
