EXTRUSION – PLASTIC SHEET PRODUCTION
Plastic extrusion is a manufacturing technology process where hot forming using thermoplastics can produce a complete finished product of any desirable shape, and ‘infinite’ in length.
This production process uses small plastic granules that are fed into a closed, cylindrical, heated processing section, the so-called screw, in whole batches. The function of the extruder screw is to continuously provide the granules forward as it melts the plastic raw material from the friction due to the rotation and the heat applied.
The molten plastic material is discharged to the end of the extruder machine through the head unit of the equipment to develop the desired shape. This plastic melt is cooled, thereby solidifying and stabilizing its body. The continuous production technology of extrusion allows for large quantities of products to be produced economically with this moulding process.
Since thermoplastics can be reshaped countless times during melting, these products can be recycled well after their selective collection. Our company produces plastic sheet wound by extrusion process. The plastic sheets we create are made of polypropylene with a thickness of 0.4 to 1.2 mm and a width of 800 mm.
With our twin-screw extruder, we can produce transparent products, coloured in their material, or even different in colour on both sides. By converting the flat foil we make at a later stage of production, we produce disposable food boxes and logistics trays.
