(E) Process of Production:

1) Methodizing of pattern drawings

    1. Type of pattern :One piece, split, multi piece, cope and drag,sweep

                                       As per buyer's requirement.

    1. Type of moulding   : Sand moulding in cope and drag, floor.
    2. Type of core       : Sand cores (CO2 process)
    3. Time of poring     : In seconds.

2) Pattern making

  1. Wood pattern  : In house facility.
  2. Metal pattern  : as per customer's requirement.
  3. Gating system : Poring basin, spur, runner, in-gates, rising

3) Mould & Core making

Mould and cores are generally made of sand, Muller and mixtures are used for sand preparations. Pneumatic tools are used for moulding (ramming sand).

  1. CO2 process
  2. Green sand mould
  3. No bake

4) Cupola operation.

    2. Alloying being done to obtain some specific property in the metal using silicon, copper, molybdenum, magnesia etc.
    3. Controls : Temperature, silicon and carbon contents are controlled digitally

5) Chipping and fettling / shot blasting :  Hand tool and pneumatic tools are used for these processes.

6) Machining

    1. Proof and final machining for ready to use castings.
    2. All general machines are available on the shop floor.
    3. Special machines include
      1. Plano miller having cutter dia -- 250 mm and machining dimensions upto
        l x w x h -- 7 x 1.5 x 1.5 meters
      2. Boring machine having machining dimensions upto l x w x h -- 8 x 4 x 4 meters F)
