Our engineers ensure that upgrades are incorporated to improve output, reduce cycle times and give added functionality to the equipment. Consistent cooling and efficient heat transfer is ensured by technically embedded cooling channel layout & turbulent water flow. Complete ambit of product design, mold design, mold analysis and mold process simulation occur within a design studio which has been exclusively set up for the same so that the end user receives a finely engineered product.

Karamsar Technology manufactures mold systems for all types of Preform designs and PET machines, and its range of molds for Preforms includes molds up to 64 cavities.

Our products for their sheer precision and durability are one hand admired by our customers and on the other hand are envied by our competitors.

As our molds have intrinsic perfection in their designs, it is possible to easily exchange the inserts which allows development of different Preforms from the same mold. The Karamsar products require low maintenance and are highly power efficient.


  • Karamsar offers molds up to 72 cavities.
  • A perfectly balanced hot runner ensures uniform melt flow and pressure in all the cavities.
  • Our molds are known for their extreme reliability and long life.
  • The molds ensure fast & reliable ejection of the Preform.
  • Best sliding properties of all moving parts ensures minimal maintenance cost.
  • An excellent after sales service and overall competence are important to us – as much as our customers.
  • We don’t save on R&D; and thus we save you costs and energy.
  • Gate free Preform.
  • Low Preform eccentricity, not more than 0.1/0.2mm.
  • Low I.V. (Intrinsic Viscosity Loss) Loss.
  • Low weight variation between cavities, less than +/-0.2 g.
  • Excellent Perpendicularity.
  • Low Preform temperature at exit to avoid scratches on Preform.
