"Pratishna" brand is known for.

  • Highly cost effective machines or solutions.
  • Low Power Options.
  • Sturdy & Strong Structure.
  • Maintenance is very easy & less time consuming as all valves are mounted on a manifold block which are easily accessible & leakages of oil is minimized.
  • Highest Reliability & Consistency
  • Very High Value for Money.

Injection Unit

Geometrically design gas nitrided screw for high plasticizing capacities

Pre and Post suck back function.

Injection movement is actuated by two hydraulic cylinders for perfect alignment to clamp unit.

Injection unit carriage moves automatically for sprue breaking. Manually operated electro-hydraulic control provides additional movement for affording ready access to the nozzle & the mould.

Clamping Unit

Larger moulds capacity due to increased opening stroke, mould thickness & space between tie bars

Phosphorous bronze / ultra bronze bushes with lubrication arrangement fitted in the moving platen ensure perfect alignment of the mould halves & improves the expensive moulds life.

Mould safety arrangement with low pressure mould safety to avoid damage to the expensive moulds

Electrically interlocked safety guard


Twin hardened toggle clamping unit.

Clamping force may be adjusted up to maximum figure to suit size of the mould.

Multiple stroke hydraulic ejector.

'T' slots platen for heavy duty moulds

High tensile & hard chrome plated tie rods of larger diameters.
