Product Portfolio
  • Sand blasting machines

      • Dry blasting

      • Injector method

        The injector method is based on the pressure reversal principle. In the blasting gun, compressed air is blown through the air nozzles into the blasting gun body. The air flow creates a negative pressure (optionally electronically measurable and evaluable) whereby the blasting medium is torn in via the blasting hose. At the same time the blasting medium is further accelerated with air and then hits the workpiece surface at high speed. The process can be completely monitored and even the finest adjustments are possible.

        Pressure blasting method

        In the pressure blasting process, a pressure vessel filled with blasting medium is subjected to compressed air, which presses the blasting medium directly through the blasting hose and is entrained by the air flowing through it. In this method, a very high velocity is achieved. The advantage of this method is the exact dosage of the blasting medium (optionally electrically adjustable) and a large blasting power. The machine is basically the same as with the injector method, but it includes additionally a pressure vessel.

        Shot peening machines

        The blasting medium (shot) is accelerated by means of compressed air or water and is thus fired onto the workpiece surface. There, so-called dimples are produced. The shot-peening process is a surface strain hardening.
        The individual dimples cause plastic deformation and create a limited compressive residual stress layer in the workpiece surface. This layer leads to a strong increase in fatigue strength and resistance to stress corrosion cracking. This process is used in the aerospace, automotive, tooling, medical, etc. Restec developed special machinery and equipment with this process mainly for the tooling, medical technology, turbine blades (gas turbines). Fully automated systems (robots) were realized here.

      • Wet blasting

      • Wet blasting method

        In the wet-jet process, the water-blasting-medium mixture is pumped to the blasting gun. This is accelerated by the air nozzle and thus hits the workpiece surface. This method is particularly suitable for processing sensitive, high-precision parts. It can be used for cleaning, paint stripping, stripping or shot peening. Therefore, this method is the first choice for explosive and combustible materials (aluminum, hafnium, magnesium, etc.). The big advantage over dry blast systems is that there is no dust development. The use of finest blasting mediums is enabled by this method.
        The wet blasting system WA 5000 is the most advanced machine from Restec and is absolute state-of-the-art in the blasting market.

      • Carousel

      • Carousel (turn table) machine

        Turntable systems (carousel / planetaric) enable targeted blasting of individual or several workpieces. The blasting is extremely uniform and also offers the possibility to partially radiate on the workpiece. The processing spectrum ranges from cleaning, deburring to shot peening. The dimensions of such systems depend on the dimensions of the workpieces and the desired cycle time. Thanks to the modular design, the system can be easily configured with 4 to 24 workpiece fixtures (satellites) and thus be operated fully automatically (single, series production). The integration into existing production lines and thus complete automation (for example robots, handling systems) make these systems universally applicable. All systems can be equipped with a clever abrasive preparation. These systems are available in injector, pressure or wet jet versions.

        • Carousel blasting machine KA 8/8 (e.g. with 8 satellites)
        • z-axis system
        • with fully automatic workpiece clamping system
      • Blasting medium processing

      • Elevator

        The elevator is used on our machines to transport used abrasive from the blasting cubicle to the screening plant. For this purpose, the blasting agent is passed through a bucket elevator from the bottom of the plant to the top of the screening plant.


        • Input of used blasting media via screw conveyor.
        • Output of used abrasive into the sieve.
        • The elevator buckets are screwed firmly to the elevator belt by means of 2 cup screws. By further screws, the elevator belt is also connected to a loop.
        • The tightness of the belt is secured by 2 screws on the head of the elevator.
        • The ball bearings for the elevator belt are protected by a sheet metal and thus easily accessible for any maintenance work.
        • The motor of the belt is mounted on the head of the elevator and protected by a sheet of external influences.

        Screw conveyor

        The screw conveyor is fixedly mounted under the catch basin in the blasting cubicle and transports the blasting material just used, as well as radiated impurities from the catch basin directly into the elevator.

        Process steps:

        • Entrance of the screw conveyor, where blasting media, dust and other particles fall into it.
        • Between the screw conveyor and the bucket elevator a connecting pipe is attached.
        • A sensor checks whether the conveyor is turning.

        Screening Plant

        In the screening plant, the used blasting medium supplied by the elevator is filled up fully automatically and cleaned of any impurities by a complex screening system. Too fine or too coarse abrasive is sorted out, so that in the end only recyclable blasting medium remains, which is passed back into the machine.

        Process steps:

        • Supply of used abrasive from the elevator.
        • Output of unusable blasting material (too fine and / or dust).
        • Output of unusable abrasive (too coarse).
        • Collection basin for reusable blasting medium (blasting medium thickness 850 – 1000 μm).

          Optimum adhesion is achieved through the creation of various surface structures (roughness). Through the possibility of simultaneous use of the most different of blasting media and grain sizes, several surface treatments can also be carried out in one machine. Shot peening is the most rational and meaningful process for the creation of internal pressure tensions on the surface. This evens out the tensile stress or reduces it which in turn leads to an appreciable extension of the service life. Shot peening machines for the most various of applications are a core competence of Restec and have proven themselves in the market.
