Thermoplastic spray applications are used for applying flat lines, also known as non-profiled or type 1 markings. Flat lines are mainly used in well-illuminated areas as urban roads for e.g. where the lines do not need high retroreflectivity levels.

Extrusion applications are used for applying both flat lines (also known as non-profiled or type 1 markings) and profiled markings (also known as structures or type 2 markings).

Profiled road markings are the newest road marking technology where a part of the road marking typology is raised over the road surface. This type of markings are becoming more and more popular because of the increased road safety it provides due to high visibility in wet conditions and at night, as well as the acoustic warning you get when driving on the line.

Based on your requirements and the line types you require, Borum can supply you with a variety of application equipment.

THERMOPLASTIC SPRAY APPLICATIONS

Thermoplastic spray via pressurized tank

Line types: Flat lines (continuous and interrupted lines)

Equipment: BM SP 2500 Spray plastic gun
(Optional narrow nozzle size of 3 mm or wide nozzle size of 7 mm)

The amount of product that is put on the road is regulated by the pressure of the tank and the pressure of the sprayed air. In other words, the application pressure is kept at the same level as in the pressure tank. This offers you an easy to use system.

After starting the application, the thickness of the line is only affected by the machine speed. Therefore, it is necessary to keep a constant speed in order to maintain a uniform and consistent line thickness. This is useful for applying thicker lines in curves and areas with higher wear and tear levels.

The maintenance for the pressure tank is minimal if compared to the thermoplastic spray pump system. Furthermore, due to not having a pump, the system has less mechanical parts that can be worn out in the time.  

  • Material pressure is created by the compressor
  • The pressure tank can handle 8.5 bar, but usually, a pressure of 1-5 bar is used
  • The atomizing air pressure is adjusted with the material pressure and depends on the material pressure and the viscosity of the material. We recommend that the atomizing air pressure to always be min. 1 bar higher than material pressure.
  • A minimum air capacity of 600 L/min. is needed per gun
  • Possibility to apply line widths ranging from 10 - 20 cm with one spray gun depending on line thickness, work conditions, application speed, and layer thickness.
    As an alternative, we offer a narrow nozzle, which can spray 5-15 cm with one gun.
  • Line thickness is typically between 0.75 mm to 1.5 mm
  • Working speed can be up to 15 km/h depending on the conditions, e.g. material, line type, and operator experience
  • The thermoplastic spray equipment is mounted on a slidable retainer. This will allow for work to be done on both left and right sides. This also makes it very easy to slide the equipment from one side to the other in only a few minutes and with minimal mechanical interference.

Thermoplastic spray via pump

Line types: Flat lines (continuous and interrupted lines)

Equipment: BM SP 3000 Spray plastic gun
(Optional narrow nozzle size of 3 mm or wide nozzle size of 7 mm)

The amount of product that is put on the road is regulated by the pressure of the pump and the pressure of the sprayed air. After starting the application, it is possible to set the amount of material in relation to the machine speed.

There are three major advantages when using a spray pump system:

  1. Increased safety as there is no risk of backsplash of hot material due to pressure in the tank.
  2. The ability to quickly adjust the pressure while driving. To some extent, this can be done automatically from the Borum LineMaster computer that Borum machines are equipped with.
  3. The filling and filtration of thermoplastic is easier due to the lid of the non-pressurized tank being larger compared to the pressurized one.
  • When using a pump based system, the tank is non-pressurized
  • The amount of the applied material is set by the pressure of the pump and the air pressure of spraying. It can also be set to automatically adjust to the speed of the machine through the LineMaster Computer.
  • The system is designed for pressure up to 8.5 bar, but in practice, it will typically be about 1-5 bar
  • Pump volume is up to 80 L/min
  • A minimum air capacity of 600 L/min. is needed per gun
  • Possibility to apply line widths ranging 10 - 20 cm with one spray gun depending on line thickness, work conditions, application speed, and layer thickness. As an alternative, we offer a narrow nozzle, which can spray 5-15 cm with one gun.
  • Line thickness is typically between 0.75 mm to 1.5 mm
  • Working speed can be up to 15 km/h depending on the conditions, e.g. material, line type, and operator experience
  • The thermoplastic spray equipment is mounted on a slidable retainer. This will allow for work to be done on both left and right sides. This also makes it very easy to slide the equipment from one side to the other in only a few minutes and with minimal mechanical interference.

THERMOPLASTIC EXTRUSION APPLICATIONS

Thermoplastic extruder equipment

Line types: Flat and profiled lines, profiled markings such as long flex, edge flex and chess markings

Equipment: Consists of an insulated screw pump that takes the heated material from the material tank to the extruder head

  • The extruder head is available in 3 different sizes giving the max total width of the line: 30 cm, 40 cm or 50 cm
  • The extruder head is fitted with a number of shutters for making lines as requested; standard shutters of 5 cm width (E.g. 6 shutters of 5 cm for the 30 cm head)
  • Shutters of other sizes than the 5 cm are delivered by special orders.
  • Depending on choice of head the extruder is capable of applying widths of 5 cm to 50 cm in width 
  • Multiple lines can be made simultaneously with the extruder (e.g. double lines)
  • Line thickness is usually between 2-4 mm (ribs/profiles can be up to 10 mm, depending on material)
  • Usual working speed is 2-10 km/h depending on the conditions, e.g. material, line type and operator experience
  • Effective heating of all significant parts of the extruder ensures the material does not stiffen and set inside the equipment
  • Continuous circulation of the material inside the extruder ensures a homogeneous viscosity and prevents settling of sand/glass beads
  • Built-in pressure regulating system ensures uniform line width and thickness, even when making broken and solid lines at the same time

We also offer the Borum Dot'n line extruder that can make flat and profiled lines, dot markings alone or a combination of dots on line. See videos and read about it here.
