Automated abrasive blasting machines are preferred over manual machines in situations where reduced labor costs, consistency, repeatability, and high production rates, are important. Here’s a breakdown of when automated systems are typically favored:
Reduced Labor Costs: Automated systems reduce the need for manual labor, which lowers operational costs and allows operators to focus on other essential tasks. One operator can effectively monitor multiple automated machines.- High Production Volume: When dealing with a high volume of parts, automated systems can significantly increase productivity. For example, the TT36-S automated blasting system can perform the work of eight manual blast cabinet machines. Automated systems can also run continuously with minimal operator involvement.
- Need for Consistency and Repeatability: Automated systems ensure consistent and repeatable results, which is particularly important in applications like shot peening, where precise control is needed for structural integrity. Automated systems have controls for media flow, air pressure, speed and media recovery. These controls are crucial for validation and reporting.
- Complex Geometries: For parts with complex shapes and geometries, automated systems like rotary head machines provide uniform and complete coverage. Rotary heads can access different surfaces at the same time.
- Space Optimization: Automated systems can perform the work of multiple manual machines, optimizing workspace and reducing the operational footprint of the facility.
- Specific Process Control: Some applications require specific process controls, such as closed-loop control for air pressure and media flow, which are more easily achieved with automated systems. In such cases, the automated system can monitor the condition of the blast media and report variables in real time.
- Safety: Automated systems often include safety features, such as light curtains and door interlocks, that reduce the risk of injury to operators. They also minimize the need for operators to manipulate parts during blasting which may lead to injury or fatigue.
- Integration with Production Lines: Automated systems can be easily integrated into production lines, with options like robotic loading, continuous flow and in-line systems for seamless operation.
On the other hand, manual machines may be preferred in the following scenarios:
- Lower Production Volume: When production volumes are low, manual systems may be more cost-effective and appropriate for unique applications.
- Flexibility for Handling Different Workpieces: Modified manual cabinets offer a solution for lower production volume environments requiring a robust product. These modified systems can handle a wide range of finishing needs and offer flexibility for handling different work pieces, which can lead to more efficient production processes.
- Customization: Modified Pro-Finish cabinets are a lower-cost solution when a customer needs more custom options than come standard, but not the full customization of an automated system.
- Initial Cost: Manual systems typically have a lower initial cost than automated systems, which is an important consideration for smaller businesses with lower production needs.
In summary, while manual systems offer flexibility and lower initial costs, automated systems are ideal for applications that require high production rates, consistent quality, reduced labor, and a high degree of process control.
