The preparation of metal surfaces is an important part of many manufacturing processes. Before painting, applying protective coatings, machining or subsequent technological operations, it is necessary to remove rust, scale, remnants of the molding mixture and other contaminants. Shot-blasting equipment is used to solve such problems. https://zavodnomer1.ru/catalog/telecommunication , which allows you to automate processing and get stable results.
Unlike manual cleaning, the shot blasting technology is designed for high productivity and can be used both for individual heavy parts and for serial processing of metal products. The choice of a specific installation depends on the size and weight of the workpieces, their shape, the required degree of cleaning and the specifics of the production process.
What is shot-blasting equipment used for?
The principle of operation is based on the impact of metal shot, which is directed at high speed to the treated surface. Due to mechanical action, impurities and surface defects are removed, and the metal acquires the necessary roughness.
This technology is in demand in the foundry, metallurgical and machine-building industries, in the manufacture of welded structures and the processing of rolled metal. Shot blasting units are used for cleaning castings, forgings, pipes, profiles, frames, welded structures and other products.
The main types of shotguns
The design of the equipment is selected taking into account the nature of the production. Drum-type installations are suitable for mass processing of small parts, whereas large and heavy products require a different method of loading and positioning. Flow-through solutions capable of operating as part of an automated line are used for in-line production.
- Crane type installations are designed for large—sized parts, frames, welded structures and heavy castings.
- Drum sets are convenient for mass processing of small and medium—sized parts that are loaded in batches.
- Installations with a rotating table are used for heavy products of complex shape.
- Pass—through suspended installations are suitable for continuous processing of products as part of a production line.
- The equipment for pipes and rolled metal products is designed for processing the relevant types of products before applying protective coatings.
Cleaning of metal before painting
One of the most common tasks is to prepare the surface before applying paint and varnish materials. High-quality rust removal and
