Degreasing During the Shot Blasting Process – Effective Metal Surface Preparation

Degreasing during the shot blasting process is an advanced method of metal surface preparation that combines abrasive blasting with the removal of oils, greases, and other production contaminants. This solution helps manufacturers simplify operations, reduce chemical usage, and improve surface quality before coating, galvanizing, or painting.

In many production plants, operators still use chemical cleaning before abrasive treatment. However, this traditional workflow takes more time and increases operating costs. For this reason, more companies now choose degreasing during the shot blasting process as a more efficient and practical alternative.

This innovative technology has been developed by PantaTec GmbH, a German company specializing in integrated cleaning solutions for shot blasting systems.

What Is Degreasing During the Shot Blasting Process?

Degreasing during the shot blasting process works by introducing a dedicated agent into the circulation of steel abrasive media inside the blasting machine. During operation, the agent binds oil and grease particles, while the filtration system removes them from the process loop.

As a result, the system can clean the metal surface mechanically and remove technological residues at the same time. This makes the entire surface treatment process faster, cleaner, and more reliable.

In practice, this method supports preparation before:

• powder coating,
• anti-corrosion coating application,
• galvanizing,
• thermal spraying and metalization.

Why Use Integrated Metal Surface Cleaning?

Traditional cleaning methods often involve several stages, including chemical degreasing, rinsing, and drying. In contrast, degreasing during the shot blasting process combines these activities into one efficient step. Therefore, companies can save time and improve workflow consistency.

Moreover, technologies developed by PantaTec GmbH help maintain stable blasting conditions. Because of this, businesses benefit from better process repeatability and improved coating adhesion.

• fewer technological stages,
• lower use of industrial chemicals,
• shorter processing time,
• improved adhesion of protective coatings,
• more stable blasting machine performance,
• lower operating costs.

Applications of Shot Blasting Degreasing Technology

Modern factories increasingly use integrated cleaning methods to improve efficiency. That is why this type of shot blasting degreasing technology is now used in many industrial sectors.

• steel construction manufacturing,
• machinery production,
• automotive industry,
• foundries,
• metal processing plants.

By removing technological oils directly in the blasting system, companies often avoid the need for separate washing steps. As a result, the production line becomes simpler and more cost-effective.

Traditional Degreasing vs Integrated Shot Blasting Process

Inoculation – The First Step of the Process

The first stage of implementation is inoculation, which means adding the degreasing agent to the abrasive media loop for the first time. At this point, the operator prepares the blasting system for stable and effective operation.

This step allows the PantaTec GmbH solution to start binding oil contamination and supporting a controlled cleaning process from the very beginning.

Continuous Dosing in Daily Operation

After inoculation, the installation moves into standard operating mode. Then, the system continuously doses small amounts of the agent into the abrasive media circulation. Because of this, the cleaning effect remains stable throughout the production cycle.

Thanks to this approach, steel shot degreasing works automatically and efficiently, while the technology from PantaTec GmbH keeps the blasting process clean without stopping production.

Conclusion

Degreasing during the shot blasting process is a practical and efficient answer to modern industrial surface preparation needs. It reduces the number of production steps, lowers chemical consumption, and improves the final quality of metal treatment. In addition, it supports better process control and more predictable coating results.
