I am looking for a way to clamp molds. I have a dual jacobs injection machine. I do not like to put the C-Clamps against the molds itself. I believe that this causes un-even pressure down the length of the mold. It also scratches / scars the outside of the molds. So as an example, here is what I do (example is for a single cavity mold): I use 2 peices of wood (The length of the mold, 2" wide, 3/4" thick) on the outsides of the molds as clamp pads. I use 2 C-clamps. I believe that the 2 peices of wood acting as clamp pads distributes the pressure from the clamps better than just using the clamps. It also prevents scratching the outside of the mold. My problem is that the adjusting screw (the end with the handle) then sticks out to far and I cannot center the mold perpindicular to the nozzle for dual injecting (it will be offset). This of course is not an issue when I am not using the peices of wood (just the C-clamps). I am using the smallest C-clamp possible So: - I am thinking of buying Aluminum bar to replace the peices of wood. - I would have the aluminum bars 2" longer than my mold. - I would drill holes at the ends of the bar. - Bolt, washer, washer, nut to clamp them together. This would solve my clearance problem. But these solution seems sort of expensive to me. As an example priced six 9" x 2" x 3/4" 6061-T6511 bars for my 3 senko molds. (Note, I am aware I could use the same 2 bars for all three molds but I would much rather have a pair for each mold, makes things go faster.) and came up with a price of $55.98 + $27.23 shipping. Ouch! I did not even bother to take the time to price out bars for the rest of my molds. Anyone have any ingenuise ideas to solve my clamping problem? Or maybe there is an industriouse tool & die type member here who would be willing to cut stock and drill holes for a better price? I have though of doind this with wood but I believe that the wood would just flex (bow) outward towards the center. Thanks.
