EPS Manufacturing



Expandable Polystyrene (EPS) is a raw material for making these EPS Shape Moulded products. EPS is a byproducts of petroleum oil. This is in the form of granules it contains 4 to 6% of Pentene gas is filled inside the granules. This is a blowing agent. This granules pre expanded in the Pre-expansion machine then this will be transferred into Silos as a storage unit. After getting the ageing time of 6 to 12 hours the pre expanded bead will be fed into the mould through pneumatic fillers according to the shape the mould which we fed into. Steam will be passed into the mould to expand the pre-expanded Bead further to expand and to attain the shape of the mould. After the expansion by cooling the mould it will get shrink and the same product will be taken out from the mould by proper ejections.

 Thermal Inserts:

EPS Thermal Inserts standard dimension is 400 X 200 X 60 mm, 400 X 200 X 110 mm & 400 X 200 X 160 mm. These Inserts will be inserted in the Thermal Block manufacturing sectors. This will reduce heat transmission from Inside to the atmosphere also vise versa.

ICF is an engineered system - designed by builders

Safe, Fire Rated

ICF Panels are manufactured from high density, biologically safe, fire retardant expanded polystyrene (EPS). The Building System will not support combustion. The fire resistance of a finished wall with 8" concrete thickness is 4 hours.


ICF construction gives you a solid, reinforced concrete wall - your choice of 4 to 12 inches thick. No foam tunnels through the concrete. No thin/thick sections. No worries about rotting. No insects crawling through your walls. Just solid, uniform, insulated concrete walls with standard rebar.

A modular floor slab insulation can be used in basements, garages, main floor slab on grade and above grade installations where concrete is normally used to provide lighter structure and more heat resistance.

Flooring drawing has final dimensions after shrinkage.

Notice that we can produce the following heights, depending on the configuration you choose:




 3.Wall panels


Panels dimensions will be 1800mm x 500mm and 1800mm x 400mm sizes with choice of thickness you can choose to produce the panels at 100mm, 150mm or 200mm thickness.

 Packing and Stacking:

According to the requirement of the customer Insert pieces will be packed and stacked. Standard packing Quantity 400 X 200 X 60 mm – 180 Nos. in a packet.

 Storage Silos

Pre-expanded material will be transferred to Silos for storage. Also to keep drying the pre expanded material. Storage Silos are made up of Mild steel square tubes with Nylon nets for ageing ventilation. The height of the Silo is around 5 meters capacity of around 600 kgs.

 Shape Moulding Machine

Shape moulding process will takes place in the machine. Utility requirement for the machine to run is Steam - 4 to 5 kg/cm2, Air pressure – 7 to 8 kg/cm2 & Water pressure – 4 o 5 kg/cm2. Once all the utilities are ready moulding operation will starts, In that process of shape moulding, material will be fed into the mould through the pneumatic Fillers after completion of filling steaming will takes place. According to the sequence of operation expansion will takes place. After the expansion cooling will takes place. At that time of expansion mould temperature will reach around 115 to 120 deg. Cent. After the cooling mould will attain the temperature of around 85 to 90 deg. Cent. Air will be used for extracting from the mould and ejectors will be used for pushing from the cavity.

 Pre expander machine:

Pre expansion of the material will takes place in the pre expander chamber. It is made up of Stainless Steel to avoid corrosion as well as to withstand the temperature. Temperature inside the chamber during the time of pre expansion will be around 100 to 120 degree centigrade. EPS raw material will fed into the chamber through the screw conveyor which is attached along with the machine. There will be a two hopper in the machine. From bin to First hopped EPS raw material will be transferred through the screw conveyor from there one more hopper kept in the bottom of the upper hopper. From lower hopper material will be fed into the pre expansion chamber. After the expansion material will be fed into the Fluidized bed drier, after getting dried material will be transferred to the silos.
