The production flow of wooden doors and window frames begins with the moulder, in which the three-ply wooden components are processed. As the pieces pass through the moulder machine once, it planes the pieces on all four sides. Simply put, it creates level surfaces on all four sides of the wood to create a rectangular cross-section.
NUMERICALLY CONTROLLED MACHINE FOR THE PRODUCTION OF DOOR AND WINDOW FRAMES
After processing in the moulder, the next step is the NC Machine. This machine cuts the three-ply parts to the desired dimensions and then creates the slot-and-tenon joints. Finally, the third stage is to create the profile within which the rubber insulating seals will be fitted.
FRAME ASSEMBLY MACHINE
In this machine the wooden components are assembled and bonded into their final form.
After the completion of assembly, the frames are sanded to smoothness by the belt sander.
After passing through the whole process, the frames receive their final finish.
Initial sanding of the surface and profile of the wooden frames with a hand-held sander and sanding sponge of P80 and P120 grade.
First, the frames are treated with a water-based colouring agent.
Then, they are treated with the first coat of varnish using a hand-held gun.
The frames are then sanded once again using sandpaper of grade P180 or P220.
Finally, the coating process is finished with a second layer of varnish.
INSTALLATION OF MECHANICAL COMPONENTS AND OTHER PARTS
When finishing is complete, the mecahnical and other components are installed. The work is doen on a special workbench designed for window and door frames.
The steps of the process are:
- Creation of openings for the handles and locks
- Measurement for the cutting of the locking mechanism*
- Measurement for the cutting of the window opening mechanism
- Automated screwing in of the metallic corner brackets and the locking mechanism
- Using special guides, cutting of the glazing bead* and the installation of this into the inner window frame..
*locking mechanism:the metallic element made up of the locking piston and of the tongue that slots into the door handle.
*glazing bead: the wooden element which is installed around the internal edge of the frame to secure the glass.
Finally, it’s time to install the final components, such as the insulating rubber seal and window panes, and to seal the edges of the panes with silicone.
