Casting Capabilities & Processes
Giltech specialises in the casting of all types of bronzes,
copper and aluminium. The most common bronze alloys cast are Leaded
Gunmetal (LG2), Aluminium Bronze (AB2), Nickel Bronze (NiB) and
Manganese Bronze (MnB).
We also cast a number of specialised alloys for our wide range
of customers. The most common aluminium alloy we cast is CC601
(LM25) which is able to be heat treated. While we don't do heat
treating we can arrange to have this done. Giltech casts 30 tonnes
of metal a month into castings weighing up to 250kgs. Only
certified ingot is used. We use both green sand and hard set
moulding processes and can make over 700 moulds a day.
Metal is melted using two Inductotherm furnaces which both melt
250 kgs and have two crucibles attached to each control unit.
Shell, hot box and CO² cores are used and all castings are fettled
and then shot blasted. Castings supplied for pressure applications
can be tested air under water at 620 Kpa or up to 1000 Kpa if
required.
We can provide Certificates of Analysis and/or Conformity which
can include melt codes cast on each product. Tensile and non
destructive testing can also be provided if required.
