The surface finishing of cast iron castings requires robust solutions capable of tackling ‘aggressive’ challenges. Fondstamp, a leader in the production of complex components in grey and spheroidal cast iron, has revolutionised its finishing department thanks to a strategic partnership with Tosca, a specialist in industrial shot blasting machines.
The Client: Fondstamp and the Industry 5.0 Vision
A leading player in the Italian foundry sector, Fondstamp supplies high-precision components to industries such as the automotive and earth-moving sectors. Their philosophy focuses on investing in efficient, high-performance technologies to guarantee the highest operational quality, whilst ensuring economic sustainability.
The Challenge: going beyond the limits of traditional sandblasting
In an extreme working environment, the company needed to replace an old sandblasting machine to overcome structural challenges:
- Removal of foundry sand: deep cleaning of undercuts and complex cavities to remove sand residues.
- Casting flash: the need for a flawless and consistent finish.
- Extreme environments: machinery resistance to abrasive dust.
- Efficiency and optimisation of workflows: elimination of bottlenecks (slowdowns) in the production process.
The Solution: TS-PB25 industrial overhead crane shot blasting machine
To meet these requirements, Fondstamp has chosen one of Tosca’s most advanced foundry shot blasting machines: the TS-PB25 35x60/ST2 overhead crane model. The decision was driven by a desire to build on a successful investment made in 2022, opting for a further enhanced ‘twin machine’.
Compared to other solutions such as rubber-belt and steel-belt shot blasting machines or monorail shot blasting machines, the hoist shot blasting machines (or double hoist) configuration has been preferred for handling heavy and bulky loads.
Distinctive Technical Features
- Enhanced wear resistance: full shielding for extreme durability.
- Cleaning system: secondary screening to ensure a consistently clean working mixture.
- Tailor-made integration: technical consultancy to ensure a layout that fits seamlessly into your business processes.
The Results: efficiency and tangible savings
The adoption of Tosca technology has led to immediate benefits:
| Target | Achieved Result |
| Productivity | 45% reduction in cycle time |
| Quality | A uniform surface finish, ideal dfor high-end aesthetics |
| Human Resources | Optimising staff allocation towards tasks with higher added value. The time saved has meant that the operator is no longer restricted to shot blasting alone, allowing them to devote their time to other stages of the process. |
| Reliability | Installation and commissioning carried out without any design errors |
The Future: Towards Industry 5.0
For Fondstamp, Tosca is not merely a supplier of continuous hook or hoist shot blasting machines, but a strategic partner. Our shared goal is the integration of increasingly intelligent systems to maintain the highest quality standards in line with Industry 5.0.
The partnership between Tosca and Fondstamp
Tosca’s support has been crucial at every stage: from bespoke design to the customisation of technical details.
Tosca’s ongoing support ensured that the system was seamlessly integrated into Fondstamp’s processes, delivering a solution that was immediately operational and tailored to the client’s specific requirements. No issues arose during the design, installation or commissioning of the industrial shot blasting machine; furthermore, the entire Tosca team met all expectations.
In line with the Industry 5.0 vision, Fondstamp regards Tosca as an indispensable strategic partner for innovation in finishing processes. The aim is to integrate smart shot blasting systems capable of eliminating quality fluctuations and ensuring consistently high standards of excellence. Throughout this process, Tosca’s technology has proven to be efficient, reliable, high-performing and competitive.
The partnership between Fondstamp and Tosca confirms that technological innovation is the key to overcoming the long-standing challenges faced by foundries. Investing in reliable finishing systems does not merely improve the product’s appearance; it raises the company’s overall quality and competitive standards.
