Shot blast machine for profiles, plates and welded structures
PER, EST & CH LINES
Profiles, plates and welded structures - Solution for your process
CYM Materiales manufactures continuous-pass automatic shot blasting machines for the surface treatment of structural profiles, flat rolled products, tubes, spools, and welded structures of any geometry. Each line is engineered to match the material type, part dimensions, and the customer's production requirements.
In the PER-R and CH lines, blast wheels are positioned at 90° to the part travel path, optimizing process speed for raw material applications. In the PER-I line, blast wheels are set at inclined angles, enabling processing of both raw material and simple welded structures and spools.
The EST lines use configurations of 8 to 16 blast wheels at variable angles, ensuring complete coverage with no blind spots on structures of any geometry. All lines can be integrated with shop primer systems, drying ovens, and overhead conveyors.
Applications
Uses and shot blasting processes
CYM develops equipment configurations according to the type of product to be processed. The lines are grouped into two large industrial applications.
Welded Structure Blast Cleaning
- Surface treatment of structural parts and assemblies
- Rust, weld slag, and welding contaminant removal
- Uniform cleaning on complex structures with no blind spots
- Surface preparation for painting or anti-corrosion protection
Raw Material Blast Cleaning
- Pre-process before fabrication of structures and components
- Mill scale and rust removal on profiles, tubes, and rolled products
- Surface preparation before cutting, drilling, and welding
- Conditioning for painting and coating processes

PER-I line
Shot blasting machine for profiles and structures with inclined turbines
Inclined blast wheels for processing both raw material and simple welded structures and spools. Uniform coverage on varied-geometry profiles: angle, double-T, L sections, tubes, and compound cross-sections. High versatility combined with high production volume.
Leer mas
LINE EST-ROD
Structural Steel Blast Machine — Roller Conveyor
8 to 16 blast wheels at variable impact angles for complete coverage with no blind spots on structures of any geometry. For plate girders, trusses, frames, and large welded assemblies. High production volume at minimum operating cost.
Leer mas
LINE CH-H
Horizontal-Pass plate shot blast machine
For flat plates and H profiles in horizontal position. Equipped with rotary brushes and blowers to remove abrasive accumulated on parts. Integrable with shop primer booth and drying oven for a complete surface preparation and coating line.
Leer mas
LINE CH-V
Vertical-pass plate shot blasting machine
Plates processed in vertical position. No brushes or blowers needed, eliminating abrasive buildup points. Lower investment and maintenance cost than horizontal-pass machines. Compatible with spherical or angular shot for different surface roughness profiles.
Leer mas
EST-TUN LINE
Tunnel-Type Structure Shot Blast Machine
For all types of parts in suspended load: from small components to large structures. Compatible with Power and Free systems and automated painting lines, eliminating part handling between processes. 8 to 16 blast wheels guarantee complete coverage with no blind spots.
