EPE & EPP Extrusion line for sheet production

ALEMO extrusion lines for EPE and EPP foam are designed to extrude foam sheets with direct gas injection.

ALEMO extrusion lines for EPE and EPP foam are designed to extrude foam sheets with direct gas injection. For small production capacity, up to 150kg/h real production, ALEMO offers a single screw extruder, 90mm diameter especially designed for thin film production of EPE foam. The design of screw, barrel, die and rest of the downstream is especially developed to optimize the process for low medium and high densities. Process high reliability is achieved by different hardware and software solutions.

For high-output PE foam processing a counter-rotating twin screw foam extruder was developed. It allows melting, mixing, and cooling with minimum shear in material. The extruder’s feed-screw is designed to bring the material to the desired temperature with optimal gradient cool down, which is considered essential in foam extrusion for maximum density reduction.

Extrusion line for XPS profiles/cornices

The extrusion line for XPS cornices is designed to produce, through a process of hot extrusion, special extruded polystyrene foam profiles. The compound of the various components is prepared in a mixer and pneumatically transported to a dosing device, which feeds the mixture into the extruder. In the extruder the mixture is heated to the melting temperature of polystyrene. After that, CO2 is added to the melted polymer mixture, which fulfils the function of blowing agent, which is necessary for the production of solid foam.The obtained mixture of polymer and gas is further mixed and cooled by special cooling units, designed to work at high pressures. The mixture is then forced through special dies (matrix) necessary for the formation of the desired profile. This profile is guided through mandrels which give the desired size. During this process the profile is further cooled to maintain the desired shape and dimension. After leaving the mandrel, the profile is drawn by a rubber belt pulling device. Finally the profile is cut by an automatic cutter on the desired length and transported to an area, prepared for the packaging.

Plank lamination and Bag-making+cutting machine

ALEMO's converting machines has been designed and developed on our know-how and experience achieved in the packaging sector. The machines are safe and easy to use thanks to specific technical capabilities and high quality equipment integrated inside.

The machine was specifically designed in order to achieve maximum productivity with lowest scrap ratio. The result is machine laminationg five (5) rolls in one step at speeds up to 40m/min.
The machine can laminate input material from 6-25mm thickness; for higher final thickness requirements plank to plank lamination can be performed.

The machine was designed to transform coils of flexible packaging material into various formats and bags to different sizes. Completely automatic control system allows easy use of the machine. One good experienced worker can manage two machines together.
Ropex welding system allows welding constant temperature control. Welding time, bar closer pressure and welding temperature can easily be set on the touchscreen panel which gives perfect control on production process and final product.
The design of the sheet motion control and welding / cutting system is done in a way that produces bags or sheets in precise tolerances, even when cutting more sheets at one time. Acceleration, deceleration and speed of sheet motion can be easily set to work with the parameters that best fit the worked material.
Up to six bags can be produced in one step, using the cut/weld system and slitting knives, punching the bags in-line or even do the pre-cut / tear-off cutting, transversally and longitudinally.

About us

Company details

Alemo d.o.o. is specialized in designing, developing and manufacturing various kinds of plants for foamed materials produced by direct gas injection into the extrusion chamber. Polyethylene (PE), polypropylene (PP) and polystyrene (PS), polymers involved for this application, are mostly used for packaging or insulation purposes. Established in the year 2007 with aim of becoming a market leader, Alemo has already became an undisputed world leader in machinery for thin PE foam production and on the right way to become an absolute world leader also in machinery for EPE thick foam production and other polymers.

The range of products can be divided in four main groups:

1. Equipment for production of EPE and EPP sheets
Extruders of different capacities (from 150kg/h – 700kg/h)
