Mirror Technology has a wide variety of industrial processes at its disposal. All of our
products are designed and built in the UK at our factory in Toddington.
Vacuum metallisation is the process used for creating a mirror effect on any material. The
target material is placed in a vacuum vessel. The air is pumped out of the vessel down to 1 millionth
of an atmosphere. Once there are very few air particles left in the chamber a high current is passed
through a set of evaporation wires or crucibles. They glow white hot and melt the target metal in them
until it evaporates. As there are no other particles to collide with the metal streams out from the
crucible or wire and condenses on the first surface it meets, including the target item.
Air is let back in once the evaporation is complete and the target item is coated in aluminium for a
silver effect, but also gold, copper or other materials. For a mirror effect the surface must be high
gloss, scratch and fingerprint free and adhere to aluminium. The coating myst be protected as it is very
fragile (with a paint or laquer coat).

Blow moulding is used to create perfect domes from acrylic or polycarbonate. The plastic is
heated unitl soft and then air is blown underneath it whilst the edges are clamped down. The plastic
bubbles up and laser systems hold the height of the dome while it cools. Using this process the plastic is
not touched by a mould allowing for a defect free surface ready for mirroring.
Vacuum forming is used to create the backs and other components of products in Mirror Technologies
portfolio. The process uses heated and softened ABS which is pulled by a vacuum over a mould. This
creates all sorts of shapes and the moulds can be made on site by the CNC machines.
USed for two main purposes the CNC machines can cut flat or moulded plastic to any shape required and
also create 3D moulds for the vacuum former. The use of computer control provides for accurate
repeatability and quality.
