PRESSING PROFILED PANELS USING RUBBER MAT ON HEATED HYDRAULIC PRESS6/1
I'm a french cabinet maker, i hope the following text will be understandable and precise enough.
I'm looking for a reliable method to press veneer or laminate sheets on both sides of specific 15mm (0,6 inches) MDF panels.
I want to use my 3m x 1,3m (9,9 x 4,3 feet) 120 tons hydraulic press with electrically heated platens. I'm gonna use PUR glue, set up the temperature at about 50°C for approximatively 7mn press time.
As i have no experience with this kind of process, i'm looking for any kind of info/advices/suggestion that could help in setting up the right method.
Thanks a lot for your help, i can provide more detailed info if needed.
I don't think you get a wrap by just using a silicone pad on both platens. Also the 5mm thick silicone will insulate so your press cycle time may have to be increased.
Depending on how many of these panels you need to do you may want to consider vacuum pressing them.
You can visit www.columbus-tech.com they are based in Austria and make various models of vacuum presses which could do this as well.
There was a company in Germany that made a bladder which could be used in a hydraulic hot press for your application. I am not sure if they are still in business or not.
Thanks for your answer. Silicon is a pretty good heat conductor compared to other rubber types but I haven't had time to give it a try yet. It will certainly increase the press cycle time but this isn't my main concern.
1/8 rubberized cork sheets might work. They are used as gasket material for automotive. Don't know where you would get such a large sheet though.
