Product category: Preexpanders, foaming machinery for parts and blocks (for EPS, EPP, EPE)


Every EPS production starts with pre-expansion of the raw EPS beads. So the way raw material is pre-expanded, it has significant effect on the production process in terms of  durability and cup quality. Inovas decided to develop batch type pre-expander, due to their better density repeatebility and  purposely optimized for EPS cup production. The main advantage of the Inovas pre-expander is use of heated-air/steam mixture in the pre-expansion process. The resulting pre-expanded beads are advantageously very dry, have superior expansion capabilitiy and can be used immediately in molding of cups and containers. For this reason Inovas raw material treatment has the lowest footprint in industry without need for drying and sieving units and also big silos for ageing. One small silo 1m³ is enough for feeding 3-4 EPS cup machines.

Some of the distinctive features of the Inovas pre-expander are: 
  • Automatically raw material transport to dose hopper with vacuum system
  • Stainless steel isolated vessel
  • Integrated electrical heater for the hot air with precise temperature control
  • Air assisted transport of the expanded material to the silo
Summarizing the advantages 
  • Uniform and repeatable result – due to batch type pre-expander
  • Fully automatic from the the raw material ‘octabin’ to the silo
  • Small steam consumption < 2kg/h
  • Lowest footprint

About us

Company details

The Inovas team was joined in 1999 as a endeavor of company and individuals with main target EPS cup machines with extremely low energy consuption.

A key to this goal was inventing a mould with inovative design and technology to make it. In the middle of the year 2001 we create a machine which produces EPS cups with 10 times less steam consumption than the existing machines on the market.

Since then we started experimental production  of EPS cups and kept improving our machines and moulds till achieving durable and reliable operation for trouble-free production.

In the begining of 2006 after 100 million EPS cups produced we sell our prototype machines and INOVAS was born as a company offering machines and sollutions for EPS cups manufacturers.

Inovas EPS cup equipment was recognized by the customers as a technological breakthrough offering highly reliable and cost-efective solution on small footprint.

In recent years Inovas developed and completed it’s portfolio of EPS equipment, so we can operate as a turnkey solution provider for a complete EPS cup production.
