Cym Materiales SA manufacture automatic shot blasting equipment for welded structures, plates, profiles, bars, strips, plates, plates, spool tubes and continuous passage tubular scaffolding, adapting to the needs of each client.

The shot is driven by centrifugal turbines that vary in quantity, positioning and power depending on the type and size of the material to be shot and the required process speed.

Depending on the characteristics of the process and the requirements of each client, the pieces can be moved with a parallel roller bed for horizontal passages or overhead conveyors, allowing the latter to process pieces in suspended load working in line with painting processes.


Three models of shot blasting machines allow you to select the correct equipment for each application:

  • PER R Equipped with 4 turbines and located at 90 ° with respect to the passage of recommended parts to process raw materials (angle profiles, L, H, etc. and tubes)  
  • PER I : Equipped with 4 inclined turbines with respect to the passage of parts, they can process simple welded structures, spools and raw materials. Complex welded structures can be processed by passing twice through the equipment so that they are properly shot blasting
  • EST: Process all types of welded structures, spools and raw materials. Equipped with 8, 12 or 16 turbines, blasting the parts at multiple angles of impact achieve a correct cleaning and homogeneity. The conveyors may be a parallel roller bed or an overhead rail conveyor that introduces the parts into the chamber continuously. The machine may be equipped with in-line painting to avoid costly secondary handling of the parts.


The main uses and applications of shot blasting equipment in the steel manufacturing industry are as follows

  • Pre-blasting of raw material
    • Process prior to the manufacture of welded structures
    • Elimination of lamella and rust, improving the cutting, drilling, welding processes, etc.
    • Decreases the level of dust in the facilities
  • Shot blasting of welded structures
    • Process prior to the application of a coating (paint)
    • Leaves the surface clean, free of rust and lamella
    • Increased surface roughness improving the anchorage of the coating to be applied

Alternative and complementary machines

Preservation lines

  • Recommended when manufacturing time are lengthy or for a long storage times period
  • Complete blasting and painting lines
    • Horizontal passage (CH-H) for raw materials, plates and H profiles and pipes
    • Vertical passage (CH-V) for plates
  • Shot blasting machines are complemented by paint booths and in-line drying ovens for shop primer applications, thus avoiding unnecessary manipulation of parts with high productivity and low operating cost

Paint booth for welded structures

  • The 3D continuous flow combined shot blasting, painting and drying facilities are an ideal solution for the treatment of all types of welded structures 
  • The 3D continuous flow line, developed for processes that require high production, process flexibility and diversity of parts, allows to apply coatings on elements of different shapes, weights and sizes.
  • The 3D concept significantly reduces the area occupied in the paint line, minimizes downtime, ensures quality in the treatment of parts and works with a minimum operating cost.

  • Flexible blasting process allows to process all kinds of pieces that, due to their size or complexity, cannot be processed in automatic shot blasting machines
  • One or more operators are inside the blastroom during the blasting process using pressure blast pot to project the abrasive.
  • A protective suit and a helmet protect the operator from abrasive impact,
  • In combination with nozzle manipulators installed in the blastroom, surfaces can be automatically processed

Advantages of wheel blast machines

  • Higher production volume, minimizing operating cost.
  • Enhanced finish consistency of processed pieces.
  • Automatic shot blasting process, which does not require skilled labor.
  • With proper equipment operation, there are no health problems for the staff, or damage to the facilities.
  • They do not pollute the environment
