A summary of the five major foundry clusters in India – Belgaum, Batala/Jalandhar, Coimbatore, Kolhapur and Rajkot – is provided below.
The foundry industry at Belgaum caters to a wide variety of end-use applications as can be seen from the table below.
|Automotive/oil engines||31 %|
|Electric motors||10 %|
|Tractors/agricultural implements||7 %|
|Food processing industry||5 %|
About 40% of the foundry units have electric induction furnace, which are used either as the main melting furnace or for duplexing with cupola. A relatively small percentage (about 5%) of the foundry units use rotary furnaces.
Most of the foundry units cater to the needs of the domestic market. A small percentage (about 10%) of the foundry units are also exporting castings. Nearly half the number of foundry units are manufacturing castings for the pump-set industry. The distribution of the foundry units by end-use markets is given below.
|Food processing industry||7 %|
|Textile machinery||6 %|
|Electric motors||6 %|
Cupola is the predominant melting furnace employed by the foundry units. Majority (about 70%) of the cupolas in the cluster are of conventional designs. Electric induction furnaces are used by just 10% of the foundry units, mainly to manufacture graded castings and for duplexing operation.
The foundry units at Batala and Jalandhar are predominantly making machinery parts and agricultural implements. Castings for a number of other end-use applications are also produced as can be seen from the table below.
|Automotive/oil engines||8 %|
|Tractor parts||6 %|
|Machine parts||33 %|
|Agricultural implements||35 %|
Cupola is the predominant melting furnace employed by about 95% of the foundry units at Batala and Jalandhar. The majority of the cupolas are of conventional designs. The foundry units at Batala and Jalandhar usually use high-ash coke in the cupolas.
A significant percentage of foundry units (about 25%) at Kolhapur are exporting castings. The foundry units cater to a wide range of end-use sectors, as can be seen from the following table.
|Automotive/oil engines||42 %|
|Sugar industry||6 %|
|Tractor parts/agricultural implements||4 %|
Cupola is the predominant melting furnace employed by about 75% of the foundry units. The majority of cupolas in the cluster are of conventional type. Divided blast cupola (DBC) can be found in some of the foundry units. Most of the foundries use low ash coke. A number of foundry units (about 40%) have electric induction furnace, which is used to manufacture graded castings and for duplexing with cupola.
Apart from oil engines, the foundry units at Rajkot cluster caters to a number of other end-use applications, as can be seen from the table below.
|Oil engines||42 %|
|Machine tools||11 %|
