Polmac Ironmongery Showing Round, Concealed Metal Hinges
However, the most popular hinges are made from pressed, sheet steel with a brass, or nickel plated finish, as they are elegant, durable and economical.
Hinges with a special black, or bronze finish, as well as solid, polished brass hinges are also used where specified, although they are more expensive.
Brass and nickel plating on metal hinges is used primarily as a decorative finish but does also provide excellent wear and corrosion resistance.
Hinges must always perform one important function: To secure the lid to the base of the box and allow it to be opened and closed smoothly along a hinged axis, in perfect alignment
No matter what type of hinges are used, they must also enhance the visual appearance of the finished wood boxes. We therefore use special 'concealed' metal hinges as standard, unless otherwise specified.
These hinges are supplied round, hexagonal, or rectilinear in shape and are fixed at the back of the wooden boxes, where only the narrow knuckles are visible, on the outside and the inside, providing a visually appealing, 'clean' look.
The two flanges of the concealed hinges can be a smooth finish, or have raised 'prongs' in the surface, to increase resistance to extraction.
The fixing process is as follows ...
Firstly, two thin slots are cut into the ends of the base and side panels at their intersection, ready for the hinges to be inserted.
Secondly, the ends of the side panels are cut full length at 45 degrees to each other, creating an overall 90 degree joint. This is a special 'stop feature' which restrains the lid at the vertical position when opened and prevents damage to the hinges.
The hinges are then inserted into the slots and the fixing positions pre-drilled. Special serrated, 'disappearing' pins are then inserted and carefully hammered home.
For small, wooden boxes 6 - 8 mm serrated pins are very effective and these are hammered at a slight angle, to provide a secure and permanent fixing.
The pin holes are then filled with wooden plugs and sanded off, for a smooth, even finish.
