Fast drying glue and Case Clamps12/18/15
Good afternoon woodworkers! I am looking for the fastest drying glue on the market, for dowel construction case goods. We are looking to improve our assembly time in a high volume manufacturing facility. I am also curious as to what the best case clamp on the market is currently. Any help would be appreciated! Thank you!
What about an RF drier?
For really high volume, you skip the clamps and couple this with a pneumatic press. I can help with the glue, but we don't sell larger equipment very much.
Glue dry time has nothing to do with the rate of case clamping! Best case clamping, greatly depends on your rate of production. Automated flow through via conveyor will do the most cases per day. Time in the clamp measured in seconds. Watch the videos of European kitchen cabinet manufacturers.
Thanks for the responses, I am interested in the PUR adhesive concept. How much time do you have between glue application and assembly time? I am looking for something I can glue up, put into a case clamp, unclamp within seconds, and have a structurally sound case good. We are a very large manufacturer and currently use a standard yellow wood glue, which has to sit for 20 minutes in clamped, assembled form before being unclamped and sent onto the finishing department. I am looking to eliminate as much of the 20 minute wait as possible. Thanks for the help!
Jeff, I would love to learn more about this. Any info you have including glue delivery systems would be greatly appreciated. My email is firstname.lastname@example.org. If a phone call would be easier I can be reached at (585) 991-8407. Thank you.
I agree 100% with Larry using any white glue and you can have the cabinet out of clamp in as much time as it takes to fasten on back. Never heard of clamping cabinet for 20 minutes. I would bet you will have tough time knocking cabinets apart after 5 minutes without damaging parts using white glue.
One way you can speed up production with out changing glue is by the way you unload the box from the clamp. I've seen companies clamp for only 1-3 min because they slide the box off without lifting it and putting strain on the joints. This usually involves staples and hot melt as well. If you're looking for times fast then that, I would look to getting another clamp.
In my opinion, Gannomat case clamps are the best on the market. They have a top and bottom spindle instead of rails on the bottom which makes them last longer.
"We are a very large manufacturer and currently use a standard yellow wood glue, which has to sit for 20 minutes in clamped" Why? Something is very wrong with your operation.
Just like the one you have, the newer Gannomat clamps run on "electric screw" aka spindles. Instead of them using a brass rail on the bottom to guide the vertical beam, it has a spindle that is syncronized with the one on top. Just like the two that drive the horizontal beam up and down.
If you use a brass rail to guide the bottom of the vertical beam back and forth two things happen. One, you don't get the exact same pressure across the entire beam as when you have the top and bottom spindle. Two, the brass rail wears down much quicker which makes the beam out of plumb when it clamps. Then you get boxes with joints that aren't at a right angle.
Having the two spindles make the clamp last a lot longer. Hopefully I explained that correctly.
The reason for the lengthy dry time is the amount of time/length the unit travels after they are clamped is extensive. Our finishing process can take up to two days all while traveling on miles of conveyer. The 20 minute dry time (yellow wood glue) ensures there will be zero joints that will open up. We allow no gaps at all, so the smallest joint failure would cause rework. As you eluded to, these do not come apart once they are clamped.
High Volume and 20 minute clamp times don't compute. Neither does spending two days to finish a box. Very poor plant layout if miles of conveyor are needed to get a box to shipping. Properly done a doweled case, clamped 3 minutes does not open in the joints. I wouldn't normally recommend an industry consultant but you guys are in desperate need. Maybe something as simple as having a representative from Gannomat, Homag, Biesse, SCM come and offer solutions. Not a machinery salesman!
I think the UV glue may be a good choice. UV glue could be cured by UV light in 1s. would you be interest in it, send me email: email@example.com
How do you get UV light in the joint? If it cures in one second you can't expose it and then assemble & clamp!
Good point Larry, I can hardly wait for the answer.
