A new era in the production of PET preforms

XTREME is a rotary platform for manufacturing preform at high productivity and efficiency. With this revolutionary injection-compression molding system, SIPA has taken PET preform production into a new dimension. XTREME permits the highest L/t ratios in the industry, enabling you to produce preforms that are 8% lighter than even the lightest preform produced by conventional injection molding. And with a much faster mold changeover time of only 1 minute per cavity, a much lower injection pressure reducing material stress, AA levels and energy consumption, the possibility to produce two different preforms simultaneously, a 100% preform inspection capability, and with a much more compact footprint, XTREME redefines just about every boundary in the industry. Giving you almost unlimited freedom to design and produce extremely light preforms for mineral water and aseptic bottles with the lowest TCO. Extremely efficient, extremely flexible, extremely fast.


  • Lowest TCO in the industry
  • Highest ratio (L/T), design freedom
  • Totally oil free
  • Significantly reduced footprint
  • Reduced material stress due to lower injection pressure: low AA content and IV drop
  • In line preforms inspection: 100% camera quality control
  • Simultaneous production of two different preforms
  • Less material: 8% lighter preforms without losing any key properties
  • Extremely quick mold changeover (1 minute per cavity)

XTREME, rotary preform injection-compression systems produce a wide range of light weighted preforms with the freedom to create new and unique designs. There is almost no limitation on wall thickness, and L/t can be up to 80 – close to twice that normally possible with injection molding.

  • recycled PET
  • R-PET flakes


  • extreme lightweight
  • Preform revolutionary design: longer preforms with very thin thickness

A unique solution for the Circular Economy: from 100% FLAKES to FOOD-GRADE preforms

The first circular system in the world that produces preforms and bottles while saving the environment, energy and money.
SIPA teams up with EREMA to present XTREME RENEW, the first technology in the world to PRODUCE PREFORMS FROM 100% R-PET WASHED FLAKES IN A SINGLE ENERGY CYCLE. An environment-saving and cost reducing technology, this revolutionary “bottle-to-bottle” system was designed for the circular economy: XTREME RENEW uses fewer raw material (-8%), saves more energy (-30%), has a low TCO (-15%) and reduces logistic cost (-20%) compared to any other technology.


  • Production of PREFORMS containing up to 100% rPET from simply washed flake to food-grade PET with virgin-like quality
  • Major process simplification
  • Safe and approved process (FDA, Efsa, Invima, Anvisa, …)
  • Top preform quality: IV stability, top color values, clear preforms, food-contact compliant
  • Sustainable process, from waste to resources
  • Up to 15% lower TCO vs. traditional recycling concept
  • Major energy savings (30%) vs. traditional recycling concept
  • Up to 20% reduction in logistics/warehouse vs. traditional recycling concept

XTREME RENEW produce a wide range of light weighted food-grade preforms with up to 100% r-PET starting from simply washed flakes for a wide range of applications: mineral water, juices, RTD tea, milk.

Business lines




technical molding



Energy efficiency is a concept that in our part of the world became important towards the end of 2008 and the beginning of 2009, at the outset of the world economic crisis. Most business people had, until then, mostly declaratively considered power consumption as a significant element of the total cost analysis. In these considerations, the impact of energy efficiency on the environment pollution had hardly been tackled at all.

Neofyton was among the first companies in Serbia and the region to start actively demonstrating the importance of energy efficiency, both by cutting production costs and therefore increasing profit rates and building awareness of the resource shortage and broader ecological principles.

Energy savings through the use of Neofyton's machines

In comparison with our direct competitors in the field of plastics injection machines, and with the utilization of standard hydraulics with integrated so-called "smart" pumps, our machines consume as much as 50% less energy. The use of servo-hydraulics opens up the potential of savings as high as 70%. We have a very precise power consumption measuring device to prove this.

The company Engel was the first plastics injection machine manufacturer back in 2009, which introduced the power consumption page as a standard component of the control assembly – "Ecograph", where - next to the weight of each product (molded part) in every cycle - total hourly consumption is shown, as well as the specific power consumption per one kilogram of processed plastics (kWh/kg).


The equipment we represent contributes to ENVIRONMENT PROTECTION in several ways.
When it comes to ancillary equipment, above all water chillers by our supplier Eurochille, used for temperature control of both hydraulics and machine servo motors and molds (tools) in which finished products are made, the chiller systems we sell facilitate the use of a new cooling system based on the so-called "adiabatic effect".

In summer, the hydraulics and servo motors of the injection molding machines call for cooling with water at a maximum of 28°C. Using the so-called "free cooling" device with the "adiabatic effect", cooling of process water is performed without cooling compressors (which use freon as the heat exchanger). Heat exchange, i.e. cooling happens exclusively by the use of ventilators, which translates into six- to eightfold savings compared to traditional chillers that use freon-based compressors.

One of our customers has reduced the required cooling energy by 1.400.000 kWh per year, i.e. by about 70.000 EUR, using the "adiabatic" cooling devices. An additional benefit is the elimination of major pollution risks which might arise from emissions of freon into the atmosphere due to tube puncture or breakage.

A similar calculation can be applied to our Engel injection molding machines, as well as to the Piovan granulate dryers.
