Automated dry ice blasting

Absolutely in line with the trend

Continuously clean surfaces play an important role in any manufacturing industry, especially the automotive industry. Simply being clean is not nearly clean enough. Nowadays, the demands made on surface quality before finishing are many and diverse: the surface must be fat-free, without fingerprints and with no micro-particles before it can be coated.

The solution of White Lion

With its fully automatic, innovative CO2 cleaning technology, White Lion offers an excellent solution for surface pretreatment. All important parameters, such as air pressure, volume and dry ice pellets, including their size and throughput, can be set independently. The same applies to the speed of treatment. This variable control of the CO2 blasting unit produces a perfect surface for any type of finishing.

Here, the geometry and material properties of the workpiece play a decisive role – brass, aluminium and plastics can be successfully treated with this method.

White Lion equipment speaks every robot language – and can therefore be used with any commercially available robot. Separate X/Y axis movements are also supported, depending on the demands of the application.

With this fully automatic procedure a high number of workpieces can be processed economically and effectively. As a rule the technique can be employed before coatings or for plastic deburring in the automotive industry.

Secure by any account

The dry ice blasting process has a high noise level – a problem that White Lion deals with masterfully. The soundproofing supplied by our partner companies is tailor-made for our equipment. These companies are established problem solvers in the field of noise reduction. Enclosed in a soundproof booth, our units can be operated without discomfort. The excess CO2 can be extracted directly – there are sensors in place to control it.

Uncompromising alternative: the WL 5000 Robby Plus

Two in one – the dry ice blasting device with the plus: White Lion WL 5000 Robby Plus can blast as well as produce dry ice.

One of the most important conditions for the treatment is the CO2 supply for the production of the required blasting medium dry ice. Normally it is used in the form of dry ice pellets with a diameter of 3 mm and a hardness of 2 Mohs. The standard dry ice pellets cover a majority of possible use cases.

In special use cases White Lion can produce pellets with exactly specified size and volume. The application of specially designed so called scrambler nozzles enables a wide range of pellet size.

For this reason a 100% satisfying solution of your task is possible. Together with our customers we develop the dry ice blasting procedure a step further every time.

Additionally the dry ice blasting machine WL Robby Plus can produce the needed amount of dry ice autonomously and exactly. Thus the manual supply of the reservoir is no longer necessary. Sensors detect the filling level. The dry ice gets produced in an integrated unit and is then transported directly into the dosing unit.

This totally automated process is very safe to operate and comfortable in terms of control. This takes the load off your staff, so that it can attend to its main tasks.

Our partner companies are worldwide leading vendors of technical gases and therefore reliable partner for a trouble-free raw material supply

The highlights of the dry ice blasting machine WL 5000 Robby Plus:

  • Produces its own blasting medium (dry ice pellets)
  • The dry ice delivery volume can be adjusted steplessly: 20 – 140 kg/h
  • High quality material components, stainless steel / anodized aluminium
  • Special coatings, no adhesion of the dry ice pellets
  • Dry ice pellets of highest quality
  • Very good material flow as no pellets clump due to humidity
  • robot communication interface as desired by the customer
  • Up to date, modern machine technology and process engineering

No automation without raw materials

One of the most important criteria in the treatment process is the CO2 supply. We have a network of competent vendors of technical gases at our disposal and together with our customers we will find a reliable partner for a trouble-free raw material supply.

To find the optimum supply solutions for different applications, you need experience. This experience is what our application engineers bring to the table when they analyse our customers’ specific needs and work out an ideal solution that is precisely tailored to the manufacturing process in question. This ensures the process reliability that is so essential.
