SML extrusion lines are engineered to last for decades. However, due to the fast-paced advancements in technology within the electronics industry, some essential components of extrusion lines, like frequency inverters and PLC components, are only available on the market for a limited time. While this rapid development is beneficial for the consumer electronics sector, it poses a challenge for industrial machine operators who may find it difficult to obtain spare parts. By addressing the topic of retrofitting at an early stage, customers can avoid the pitfalls of discontinued spare parts and ensure the long-term success of their operations.  

Individual solutions to secure line availability  
Retrofitting can be a highly economical method to secure line availability and productivity. With its retrofit programme, SML offers customised solutions for upgrading lines with the latest electrical equipment. This includes options such as a complete replacement of electrical components, replacing key components or simply upgrading the PLC. SML’s experienced electrical engineers work closely with customers to develop optimised retrofit solutions.  

Economical and technical benefits  
It is crucial to address the topic of retrofitting at an early stage rather than waiting until spare parts are no longer available. Retrofit projects are complex in engineering and require thorough planning, so sufficient lead time is needed. Additionally, upgrading to the latest hardware can be economically advantageous, as the prices for discontinued spare parts tend to rise rapidly. In many cases, especially with frequency inverters, modifications can be more cost-effective than direct replacements. Moreover, since electronic components have a limited lifespan and become more prone to failure over time, a retrofitting project can increase plant availability. Besides the economic benefits, there are also technical and usability advantages due to modern electronic and operating components, as well as improved remote service support.
