Hi Tom
I cant use plastic rods. Each unit has 80 layers and I would need about 1600 rods between those layers, so using rods could be very time consuming. Beside that, because of layer structure of units I cant heat both side of the rods to activate them. Finally my PP sheets cant tolerate...
"It is not reasonable to expect that you can selectively reactivate only the "bottom" of a previously applied bead."
"It is not likely that you can uniformly heat many beads of previously applied hot melt deep within a stack of insulating material."
this is my exact problem. I've seen something...
When I said I can simply control shape and formation of my hot-melt glue, I used the word simply to compare my method with other methods for example ultrasonic welding.
You know I can control the shape and formation with acceptable margin of error
the nozzle changing thing is a example of what...
I can customize glue strips specification like their shapes, thickness or space between them in order to have different airflow channels, simply by changing glue applicator nuzzles. Ultrasonic welding or any other technique cant bring this much flexibility to my design.
I've made a sample already using general purpose glue and thin woods as spacers. I want replace those thin woods with adhesive.
I got the idea from a video. as you can see those strips are hot melt adhesive. in that video those adhesive strips are reactivated by hot water steam or something like...
For a project (an evaporative humidifier), I want to stack some polypropylene sheets to create a unit of multiple airflow channels. So between each two sheets there should be some spacers to form those airflow channels.
in my designs these spacers are made using hot melt adhesive strips.
The...
