Bridgewater Wholesalers Inc. (BWI) in Branchburg, N.J., says it has increased door production immensely after switching to the 3M Jet-Weld Thermoset Adhesive System. BWI reports an increase from 75 custom doors per week to 300 per week. 

The Jet-Weld Thermoset Adhesive System is a self-contained system that combines the speed of a hot-melt adhesive and bond strength associated with a two-part structural adhesive, according to 3M.

At Bridgewater the Jet-Weld System replaced white glue for bonding 1-1/8 inches square fir reblock strips between hardboard door panels. The Jet-Weld adhesive cartridge is inserted and heated in the 3M Jet-Weld II Applicator. A bead of adhesive is then applied at 250 degrees F to the strip and hardens quickly as it cools. Clamping time on the door is only five minutes compared to five hours with the white glue.

Design Tool Inc. (DTI) of Conover, N.C., offers the DTI 5000 automatic feed screwdriver systems, which offers a barrel design thus the operator cannot drive screws faster than the machine will deliver them to the gun. This design also allows for a product that is smaller and lighter than comparable machines, according to the company. 

DTI adds that the uniqueness of the patented feed mechanism makes the machine less likely to experience mechanical failure. The machine shuts off automatically if the unit is not cycled for 7-8 seconds and restarts when the operator drives another screw.
