Scope of work carried out:-

Machine was completely stripped down and built from base :

The tank was thoroughly cleaned and drained off old debris accumulated over the years.All fittings/ pipes were flushed out thoroughly and seals replaced. The machine parts were repainted.

Mechanical Work : Toggle system checked and found within tolerance. Tie Bars & Bushes found satisfactory , no scratches on bars working area. Moving Platen & Fixed Platen geometry checked and skimmed where needed. Bed plates were reground and old shoes replaced with new ones.

Hydraulics : All base valves cleaned and replace old seals with new one. All Solenoid Valves & top valve replaced Cylinder and intensification unit cleaned and seals replaced. New Pump and Motor , Suction filter & Oil filter replaced base valves , top valves Intensification unit & cylinder resealed

Electrical : The machine has been rewired with New PLC Delta

Guarding : Guards are original Buhler and adjusted and mechanically secured.
Operator side is pneumatic automatic & other side is manual. are all guards on machine , operator guard in automatic or manual

* Metric tons at 2205 lbs.

* Shot capacity is calculated: plunger area x plunger stroke x 75% filling rating specific gravity for liquid Aluminum = 2,5 or 0,09lbs/sg.in.

For magnesium alloys multiply by 0.65 for zinc alloys multiple by 2.5

For copper base alloys multiply by 3.2

* Nom. Casting area at injection pressure of 250 kp/cm2 (3500 lbs/sq.in.) = 1600 cm2 (154 sq.in)
