Highlights:

  • Innovative design of injection components: less wear, lower risk of flashing, better cooling, excellent quality of parting line
  • Easier filling ability of injection mould thanks to our XMOULD technology which reduces the friction and improves cycle time
  • Optimized cooling layout to support fast cycle times and save energy costs
  • Patented hot runner technology to minimize hot runner downtime
  • 8 millions lif cycle guaranteed without need of components refurbishing with LongLife solution
  • Special hot runners design to reduce material stress and working pressures

Solutions for life

 
As the world’s second-largest mold maker, SIPA is able to deliver global tooling programs for new molds or mold conversions from single to 144 cavities.
To ensure top quality, every SIPA mold is tested before shipping on dedicated XFORM machines. Over the years we have developed extensive knowledge of many different applications, even the most specialised ones, from narrow necks to wide mouths and thick walls.

MODELS:

Our ever expanding portfolio includes:
  • Complete molds (cold half + hot half) up to 144 cavities
  • Conversions of existing molds (full or partial changeover)
  • Mold spare parts and components
  • Hot half spare parts and components
  • Refurbishment options
  • Electronic temperature controllers

XMOULD is an innovation from Sipa which allows reduction of friction between molten PET and molding surface of the injection stacks during injection phase, allowing production of thin-wall performs with length on wall thickness ratio above 50 (L/t in the range of 50 to 55 possible), so better/optimized thickness distribution on final packaging (avoid the accumulation of material on zone as under-neck and bottom areas).

XMOULD technology gives designers the power to create lightweighted preforms which do not compromise performance of the final container. Besides the possibility to reduce preform thicknesses, this solution also improves cycle times due to friction reduction at filling phase.

Available on new or legacy tooling, only special injection stacks are required to enjoy the XMOULD technology, no changes required neither on the machine nor the hot runner. 

 

Range of solutions on shaping components to extend the life of the cold half of our preform molds (optional).
8 million life cycles guaranteed (flash < 0.2mm) without need of components refurbishing (competition = 5 million), following lifetime conditions. Significantly reduced refurbishment costs.
Hot runner with Xflow technology:
  • Best in class balancing
  • Low pressure drop
  • Increased injection speed, shorter cycle time
  • Optimal preform weight distribution
  • Low PET degradation and no dead spots
  • Easy maintenance
  • Compatible with industry standard cold halves and machinery

Gen3 nozzle:
  • Improved temperature profile
  • Reduced pressure drop
  • Easy maintenance
  • Long life for nozzle tip

Gen3 valve drive system
  • Low powder formation
  • Improved maintenance interval
  • Smart lock design applied regardless of the position of the parting line: better precision and higher durability with double tapers always implemented
  • Flange design to allow a significantly better cooling in the very critical split-line area
  • Self-centering gate insert, allows for a reduction of the parting line in the base area of the preform

Applications

Our range of solutions is wide and versatile. We can supply moulds with up to 144 cavities for standard applications like mineral water or soft drinks, however we have a wide range of solutions also for special applications like wide mouth preforms or long preforms for 5 gallon containers.
