THERMOPLASTIC EXTRUSION, SCREED APPLICATION WITH RIB FUNCTION AND COLD PAINT AIRLESS
The Borum Master 5000 series provides you with a variety of high capacity line marking machines designed for large scale jobs such as marking highways, motorways or airport runways.
The BM 5000 T RL CA is a combination machine that can be used for applying both thermoplastic and cold paint markings in various widths.
The paint material tank capacity is 440 L and the plastic material tank is 585 L. The possibility of the large material capacity naturally gives fewer stops during the day for refilling.
The BM 5000 has a two-seat slidable drive and operator section for flexible working on the left or right side.
Line types that can be applied with this equipment
Non-pressurized thermoplastic tank, indirectly heated via heat transfer oil. The thermal oil and thermoplastic material temperature is thermostatically controlled and regulated automatically according to the settings
Diesel burner system for heating of the thermal oil (and thermoplastic). Propane burner available on demand.

With hydraulic transmission. Heated center pipe for efficient uniform temperature control. Perfect melting & homogenization of the thermoplastic. Stable construction with foundation and bearings at the top of the material tank.
Non-pressurized black steel tank for water-based cold paint.
The material tank has a filling system with large filling holes. This makes the filling process very easy to manage. In addition, the large filling holes also make cleaning the tanks easy.
Agitator (mixer) driven by hydraulic motor and with manually operated reversing valve.
The screed box can apply flat lines, long flex, and ribs over a line in one pass. The Borum thermoplastic screed box is available in the following widths: 10, 12, 15, 20, 24, 25, 30 cm.
With this type of screed application, the box is dragged with constant contact to the surface. The contact points determine the line width. The material pressure is by gravity only and this is how the material is poured in the marking box. The material coming out of the box will fill up any holes, pores, or other types of road imperfections. This means that material consumption will depend on the road surface.
The screed box equipment is mounted directly on the side of the material tank.
The Borum thermoplastic screed box is available in the following widths: 10, 12, 15, 20, 24, 25, 30 cm. Other sizes are available upon request.
The equipment is constructed with one main application box covering a range of line widths, either 0 - 20 cm or 20 - 30cm. If you do not need to switch the line widths often, you have the option to only change the application opening based on your width requirements instead of changing the whole box! This makes the application equipment more cost-efficient!
The thickness for the application of flat lines is usually between 2 - 4 mm.
The usual application speed for applying ribs over a flat line is 1-3 km/h, while for screed application of flat lines it is up to 5 km/h.
RIB LINE FUNCTION
The screed box is also equipped with a rib function. This allows you to apply ribs over a line in one pass. The total height of line with rib is usually between 8 to 15 mm depending on the material. The base line is recommended to be as thin as possible when combined with ribs (approx. 1,5 - 2 mm).
The equipment is supplied with a laser that constantly measures the material level in the application box. If the material level becomes lower than 50%, the application box will be automatically refilled.
Thermoplastic material has a long-life duration with high retro-reflectivity capabilities due to being able to pre-mix glass beads in the material. Thermoplastic markings cure quickly and adhere strongly to the road surface. Generally, thermoplastic is recommended for areas with high traffic density and/or areas with low lighting as e.g. highways.
The rib line equipment is a good solution if you are only going to work with flat fixed-line width markings and rib line application.
An alternative to the rib line equipment is the Borum thermoplastic extruder with which you can apply various flat and profiled markings. The extruder also uses a different application method by extruding an even layer of material on the road surface. Therefore, if the surface is rough or uneven, the line is the same as it follows the imperfections. In other words, the material consumption will be predictable according to the adjustments and will not be as influenced by the type and condition of the road surface.
The working principle of the extruder lies in the extrusion of the hot thermoplastic material through the extruder shutters onto the road surface. This allows to switch between line types in seconds with a push of a button. No need for mechanical adjustment.
The thickness of the line is controlled by the slot gap and the speed of the machine, coupled to the thermoplastic feed rate.
Glass beads can be pre-mixed and/or automatically applied with glass bead guns.
You can choose between thermoplastic extruder of 30, 40, or 50 cm in total line width, built-up with 5 cm standard shutters (alternative shutter dimensions in the range of 4-10 cm for alternative line widths).
Effective heating of the complete unit using a centrifugal pump, 42 L/min, hydraulically driven. This ensures optimal performance and that the material does not stiffen and set inside the equipment.
The shutters have no contact with the high tensile steel drum and therefore, wear is minimized and lifetime is prolonged.
Pneumatic lifting cylinder for up/down function, operation controlled from operator’s seat.
Pneumatically controlled quick cleaning system for removal of solids left in the extrusion slot. It can be activated while extrusion is in process and is only slightly detectable on the line in the form of a moderate thickening of the layer.
The application speed varies according to the material, line type and width. Usual working speed is 3-6km/h but can go up to 8 km/h for some lines. Speed-dependent settings are possible.
The transport of material from tank to extruder head is done by a hydraulically driven auger screw pump, which is electronically controlled. The screw pump has a permanent thermoplastic recirculation system which ensures a constant flow past the inactive extrusion shutters, keeping these clean and ready for opening. This avoids settling and catching of solid parts and prevents unnecessary wear of mechanical parts.
Build-in pressure regulating system ensures that line width and thickness does not change no matter the number of shutters involved in the current marking assignment.
Thermoplastic is a durable material that cures quickly and adheres strongly to the road surface. It can be used for applications of both flat lines (also known as type 1 lines) or of thick profiled lines and markings (also known as type 2 lines).
This type of material is used on various types of roads, but you will often see it on highways or motorways as it can withstand high traffic density, it has a high visibility at night and during wet conditions and glass beads can be mixed in for enhancing visibility.
High-pressure airless spraying uses a high-pressure airless piston pump to spray the paint. This method can apply paints of high viscosity, and apply relatively thick layers in a single pass. However, the paint cannot be mixed in with glass beads as in the case of atomizing spray equipment due to the pump.
Sliding retainer frame, upon which 1-3 paint guns and 1-3 bead guns can be attached as standard. You can also opt for the option wide retainer on which up to 5 paint guns and 5 bead guns can be provided.
Easily slideable retainer from side to side for an optimal working position. Ground distance is maintained by retainer wheel to ensure a constant road marking width.
Lifting of retainer is done from the operator's seat.
The machine can be equipped with multiple material tanks, so that dual-color marking can be carried out.
Working speed can be up to 15 km/h depending on the conditions, e.g. material, line type, and operator experience.
Automatic high-performance spray gun. Nozzle set for water-based, solvent-based and high solid paints.
Possibility to apply line widths up to 25 cm with standard nozzles depending on line thickness, work conditions, and application speed. You can also choose from a wide range of nozzle sizes depending on your requirements.
High-pressure filter unit with integrated pulsation damper. Easy cleaning and maintenance.
High-pressure airless spraying uses a high-pressure airless piston pump to spray the paint. The airless spray paint is sharper and smoother than atomized spray as there is no high-speed airflow to scatter any rebounding paint.
The marked lines are neat and more clear-cut compared to atomizing spray paint. This method can apply paints of high viscosity, and apply relatively thick layers in a single pass. However, the paint cannot be mixed in with glass beads as in the case of atomizing spray equipment due to the pump.
10L pressure solvent tank for cleaning of hoses and paint guns.
The Borum LineMaster control unit is an easy way of setting and controlling your line marking jobs. The LineMaster is attached to the operator's section of the machine and gives you full control of all your line marking tasks, from line application and pre-marking to reporting and invoicing.
It is possible to store up to 99 different line types, and to arrange these in up to 30 different marking programs. You are also able to pre-set line widths, line types, colours and combinations to have them ready for marking, and can instantly adjust them on the go.
Furthermore, you are able to view the status of various parts of the machine (e.g. compressor) on the computer screen that will help with correctly maintaining the machine and avoiding break downs.
