New flow-coating profile line for waterbased preservatives has been installed at a UK joinery manufacturer.
This profile coating line is capable of processing beading all the way through to large timber sections. The waterbased coating is applied through a series of directional low pressure nozzles. Any over spray is collected, filtered and put back into the system, so there is zero liquid wasted in the system. All the internals of the machine are moplan and teflon coated.
All of the parameters can be controlled on the HMI screen.
Once coated, the timber is subjected to a series of adjustable air jets that blow the excess coating off but leaves the timber damp. This is key to allow the preservative to soak into the timber for 10 minutes after application.
The timber is removed from the end of the line, placed on drying racks and dried properly using gas catalytic infra red technology.
