Our products

Product category: Extrusion lines for flat film and sheets

Thin sheet

BG Plast has specialized in designing and manufacturing calenders for the production of thermoplastic materials. These machines are the core of the extrusion process for the production of films and sheets. Features include a precision electromechanical control on roll opening and closing which guarantees thicknesses from 0.1 to 40 mm, depending on material.

Closing force expressed in kg/cm is different according to type of polymer, being set by the size of the hydraulic pistons used for moving the rolls (between 80 and 120 kg/cm). A separate thermoregulation unit controls water/oil flow and temperature for each roll. Independent motor-reducer drive for each roll.
In case of very thin sheets there is a particular device called “cross-axis”, shifting the lower roll shaft in relation to the other rolls, to improve thickness regulation. This proves to be quite useful to assure uniformity of sheet thickness.

Sizes of BG Plast manufacturing lines and calenders vary according to the final product required by the customer. The witdh range of calender roll stacks goes from 450 mm to 4800 mm. Thanks to different type of feed-block configurations, BG Plast has faced several co-extrusion applications using up to 7 extruders.

Carpet coating

For many years BG Plast engineers have achieved great success in the production of coating lines. There are many possibilities for combining plastics with other materials such as nonwoven fabrics, moquette, natural fibres, etc.They are widely used in a variety of fields, from the automotive industry to that of shoes manufacturing and even the fair and exhibition market, to which were supplied 4000 mm width moquette rolls.

A new recent experience was a combination of 6 layers of which 3 of different polymers and 3 of natural fibres. The line produces rigid panels to be thermoformed as car doors.

OPTICAL QUALITY SHEETS

The main extruder, with bimetallic barrel and screw, has been specifically designed for PC processing, mainly in what concerns the efficiency of the venting system. The gravimetric high precision dosers guarantee constant feed rates synchronized with the gear pump and the extruder screw rpm.The co-extruder is extruding a thin layer suitable to protect the sheet against UV rays.
It is well known how critical is for the calendering system to obtain high optical quality sheets: in the 3-roll calender BG Plast engineers have applied the best mechanical and technological solutionts. The calender has three rolls of 410 mm diameter with high gloss finishing on surface with internal circulation of pressurized water flow at high temperatures.
The total width of the rolls is related to the final net width of the sheet. Standard width for this type of machine is 2300 mm for net width on sheet of 2000 mm.
The calender geometry can be varied: the upper roll turns around the central roll axis. This particular feature permits to adapt the calender to the thicknesses required for the sheet.

Roll speed transmission, motor and reducer controls have been particularly studied to guarantee a rotational movement with absolutely no vibration, an unavoidable factor to get the properties required by optical quality sheet. The extruded sheet is later protected with polyethylene film and cut to size up to 3000 mm length. An automatic vacuum sucker unit picks up the sheets and stacks them at the side. Different configuartion available upon request.
