Companies are constantly looking for ways to improve operational efficiency and reduce costs, and the Rösler Retrofit and TuneUp service offers a practical solution. This article explores how manufacturers can modernize their equipment without the financial and operational burdens of acquiring new machines, with insights from Chris Kershaw, Digitisation and Automation Manager (Service) at Rösler UK. He explains how the service helps businesses enhance performance, increase productivity, free up valuable labour, and future-proof operations.
The Retrofit and TuneUp Concept
Rösler Retrofit and TuneUp service is a comprehensive upgrade program aimed at improving the performance, efficiency, and longevity of existing shot blasting and mass finishing systems. The process begins with a thorough inspection of the equipment and an evaluation of the production process. This assessment is followed by in-depth consultations with the client to identify enhancements tailored to their specific operational needs.
While the latest shot blasting and finishing technologies offer significant advancements, many of these innovations can be integrated into existing machinery. Retrofitting provides several advantages over purchasing new equipment. One of the most significant benefits is cost savings, as retrofitting often costs significantly less than acquiring new equipment. According to Kershaw, "If significant savings can be made while improving the existing machine, this can be highly beneficial for our customers." Another advantage is minimized disruption, as replacing large shot blasting installations can be costly and disruptive. Retrofitting allows companies to modernize their equipment without significant downtime. Many older machines still in operation can benefit from control system enhancements, such as replacing outdated PLCs and HMIs with modern alternatives that improve usability and reliability. Additionally, retrofitting contributes to environmental sustainability by extending the lifespan of existing equipment, reducing waste, and lowering energy consumption.
Key Benefits of Retrofitting: Cost Savings and Performance Gains
One of the major benefits of retrofitting is cost efficiency. Many companies find that upgrading key components extends the lifespan of their machinery, making it a more financially viable solution. Enhanced performance is another significant advantage, as advanced blast wheels and modern control systems can greatly boost equipment productivity. Rösler's Gamma blast wheels, for example, provide energy savings between 10% and 25% while increasing blasting performance by up to 77%, leading to reduced cycle times. Retrofitting also reduces downtime and maintenance costs. Obsolete components can be a major source of unexpected breakdowns, but modernising control systems and upgrading core components significantly enhance reliability. Furthermore, improved energy efficiency and sustainability lower operational costs while supporting sustainable manufacturing goals. As Kershaw explains, "By bringing equipment up to modern standards, increased availability can be achieved."
Industries That Benefit from Rösler Retrofit and TuneUp Service
Rösler’s Retrofit and TuneUp service caters to a wide range of industries, particularly those where high operator workloads, repetitive tasks, and energy consumption are concerns. Automotive manufacturing benefits from automation and control system improvements that enhance precision and consistency. The aerospace industry requires advanced shot blasting for high-quality surface finishes on critical components. Foundries and heavy manufacturing operations, which use large-scale machinery that can be expensive to replace, find retrofitting a more practical choice. "Rösler machines are used in a wide variety of manufacturing sectors, and we can provide improvements in all of them, especially where there is high operator workload and high levels of repetitively," says Kershaw.
The Retrofitting Process: From Consultation to Installation
Engaging with Rösler's Retrofit and TuneUp service follows a structured approach. The process begins with an initial consultation, during which clients either approach Regional Sales Managers or contact Rösler directly to discuss potential retrofitting options. This is followed by a site evaluation, where a Rösler expert assesses the equipment condition and determines the feasibility of retrofitting. Based on the evaluation, a customized proposal is presented, outlining potential upgrades, expected benefits, and a return on investment analysis.
Once the proposal is approved, the necessary components are designed, manufactured, and installed by Rösler's skilled engineers. Finally, the upgraded system is fine-tuned for optimal performance during the commissioning phase, and operators receive training to ensure seamless integration. As Kershaw describes, "After an initial discussion, a site visit and equipment evaluation will be undertaken, followed by an open discussion around the options available and the benefits that could be delivered."
Determining Suitability for Retrofitting
Not all machines are ideal candidates for retrofitting. Several factors influence this decision, including the overall condition of the equipment. If a machine is in poor condition, a full replacement may be the better option. The availability of replacement components is another consideration, as some obsolete parts may be difficult to source, making retrofitting less viable. Finally, the potential for performance gains plays a crucial role. If significant enhancements can be achieved, retrofitting becomes an attractive and practical solution.
Common Technological Upgrades in Retrofitting
Retrofitting often involves several key technological upgrades. One of the most impactful improvements is blast wheel enhancement, where outdated blast wheels are replaced with high-performance models like the Gamma series, which improve energy efficiency and processing speeds. Control system modernization is another critical upgrade, with modern PLCs and HMIs enhancing usability and reducing the risks associated with obsolete components. The integration of automation into existing systems is increasingly popular, as it minimizes manual intervention, enhances efficiency, and allows skilled labor to be used in other key functions. "The most common upgrades are blast wheel and electrical/control upgrades, bringing efficiency, energy, and maintenance savings, and reducing the risk of extended downtime due to obsolete parts," says Kershaw.
Real-World Success Story: Impact of Retrofitting on Manufacturing Efficiency
A notable case study highlights the significant impact of retrofitting. A manufacturing client operating a shot blasting production cell required modernisation to match the specifications of a new robotic automated system. Previously, the equipment required four operators per machine per week. After the retrofit, automation improvements reduced the need for manual operation to just one operator per shift, cutting production costs per part by 75-80%. The expected return on investment was projected within 12-18 months.
Recognising that capital investment decisions require justification, Rösler offers financing options in partnership with financial institutions. "We can provide calculations showing the expected savings and increased productivity, demonstrating the benefits and return on investment," says Kershaw.
Conclusion: Future-Proof Your Operations with Rösler Retrofit and TuneUp Service
For manufacturers seeking to enhance the performance of their shot blasting and mass finishing equipment without the high costs and disruptions of purchasing new machines, Rösler Retrofit and TuneUp service presents a compelling alternative. With benefits ranging from cost savings and improved efficiency to sustainability and reduced downtime, retrofitting is an intelligent investment in the future of manufacturing. As Kershaw summarizes, "Our goal is to help customers maximize the value of their existing equipment, ensuring they achieve the highest levels of productivity and efficiency in their operations."
