The Evolution of Heavy Metal Carpentry: Innovation and High-Performance Surfaces
In the metal carpentry sector, surface preparation is not merely an aesthetic step, but a structural pillar. The Cantoni Group, an Italian leader in industrial components, has recently embarked on a path of technological transformation to respond to a constantly evolving market. To consolidate its leadership and handle bulky items such as truck containers, the company chose to invest in a new 8,000-square-meter production facility, focusing on a traceable and sustainable surface finishing process.
The Challenge: Optimizing Shot Blasting for Water-Based Coating
Before Tosca’s intervention, the primary need was to eliminate production bottlenecks and ensure consistent quality. With the introduction of a new all-water-based coating system, the quality of metal preparation became critical. The key issues to be resolved included:
- Handling of large formats: Effective treatment of skids and heavy structural steelwork.
- Adhesion and Durability:Ensuring a perfect base to prevent corrosion.
- Industry 4.0 Traceability: Need to monitor and store process data
The Tosca Solution: Automatic Shot Blasting Machine with 16 Turbines and 2 Hoists (16 tons each)
The choice fell on a custom solution by Tosca, selected for its flexibility during the plant design phase and technical expertise.
Technical Specifications of the System
The system installed at the Cantoni Group stands out for its advanced configuration:
- Blasting cabinet with 16 centrifugal turbines: A system designed for total and uniform coverage of the workpiece.
- Workpiece handling via two single-beam hoists with a capacity of 16 tons each
- Auxiliary manual shot blasting chamber: For handling specific finishing requirements or non-standard parts.
- Customized shot blasting recipes: Ability to adjust turbine rotation, abrasive quantity, and feed rate based on the part.
- Smart Factory integration: System compliant with Industry 4.0 parameters for total control of variables.
- Remote technical support
Tangible Results: 50% Reduction in Process Times and Certified Quality
Automation has radically transformed the efficiency of the Cantoni Group’s finishing department. Data collected after installation confirms the success of the investment:
- Production Efficiency: A 50% reduction in process times compared to previous systems.
- SA 2.5 Cleanliness Level: Consistently achieving an excellent surface cleanliness standard.
- Corrosion Resistance: Laboratory tests confirmed a cycle resistance exceeding 700 hours in salt spray.
- Comfort and Safety: Improved staff productivity thanks to a healthier and safer work environment.
"We chose Tosca for its reputation and flexibility. Every request we made was fulfilled with precision and speed, leading to a streamlined and measurable process."
Looking to the Future: Partnership and Continuous Innovation
The collaboration between Cantoni and Tosca does not end with the delivery of the machine. The installation, commissioning, and training services ensured that the shot blasting machine was immediately operational.
