glass is made: The way glass is made is by melting certain minerals together at
extremely high temperatures, silica is made in the form of sand and is the main
ingredient and it’s mixed with soda ash and limestone and melted in a furnace
with temperatures being around 1000 to 2000 degrees. It is made into the shape by using compression this is where a red hot
piece of glass is put into a mould and pressed with a great amount of force
that causes it to spread over the area and remove it when it has cooled. If the
glass is cooled in controlled conditions glass can be really tough also if it’s
shaped in a dome it adds extra strength
way the sheet metal is made/pressed: The sheet metal is pressed in certain
stages so the metal doesn’t tare, the way its pressed is by a man on a machine
pulling a leaver down which then stamps on the metal sheet making the part
Silicone rubber manufacturing
Silicone rubber is an elastomer
that is an elastic polymer composed of silicone itself a polymer containing
silicon together with carbon hydrogen and oxygen Silicone rubbers are widely
used in industry and there have multiple uses. Such as a bulk head light that
have an IP rating of 44, IP44 are designed for use
in bathrooms and other environments where water spray is a risk. Not all
bathroom lights are at risk of water intrusion and therefore may not need to be
Ceramics are generally made by taking mixtures of clay,
earthen elements, powders, and water and shaping them into desired forms. Once
the ceramic has been
shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in
decorative, waterproof, paint-like substances known as glazes.

head light is similar to the one we disassembled but it has extra protection
around as you can see there is a metal frame around the glass which is really
clever as it means the glass won’t break when hit by an object
headlight has been designed so the light is angled so you get a further
distance of light and it’s also designed so that if anything hits the light it
isn’t going to smash the plastic protection for the light
bulkhead light has been designed so it comes on when something is in front of
it due to the sensor built into it and the protection around the bulb is made

Recycling saves energy because the
manufacturer doesn’t have to
produce something new from raw natural resources. By using recycled materials we save on energy consumption, which
keeps production costs down. Recycling reduces
the need for more
landfills. No one wants to live next to a landfill.
