IV. PATTERN SHOPNo of pattern makers with modern facilitiesto make woodern, metal and araldite patterns are available in and arround coimbatore.Hence new patterns are outsourced.

Pattern repair, methoding etc are crried outinhouse.

1000 x1000 mm Surface table, 0 - 1000 mmdigital vernier guage, Shrinkage vernier andothermeasuring instruments available fordimensional inspection of patterns,finished castings.

Pattern storage racks to maintain patternsand core boxes in good condition withspecific locations and identifications.

V. MELTING DEPARTMENTa. FurnaceMelting department is equiped with medium frequency induction furnace of following specification.

Rated K.W : 500 K.WFrequency : 500 HzCrucible capacity : 1000 kg & 500 KgMake : Fluxotherm India Ltd.

Metal Pouring500 kg treatment laddle, 250 kg "T" spout pouringshanks and 1 ton laddle are in use.

Metal is tapped from furnace using 1 ton or 500 kgladdle as the case may be and distributed to 250 kgpouring shanks.

Using monorail system with laddle handler the metalis poured in the moulds which are in the track lines.
