About once a fortnight, a day is set aside when aluminium casting takes place.
Amongst the items produced are dog irons, wall lights, house nameplates and
house numbers.
Much care is taken in preparing the mounding boxes, which are filled with
special sand. The impression of the required article is then made in the sand,

The moulds having been successfully completed, the boxes are clamped together,
numbered and marked up according to the content, in readiness for casting.

The oil-fired furnace is started up, bringing the aluminium to the correct

|
…to be gently ladled into the moulds.

|
With larger moulds, a full crucible has to be lifted from the furnace...
|
|
….and the molten liquid poured into
the moulds by hand - a two-man job!
|
|
Once the aluminium has been given sufficient time to cool and set….
|
|
….the moulds are ‘knocked out’….
|
|
…. revealing the various components.

The completed article
