Lifecycle of automotive metal racks: durability, maintenance and refurbishment

The service life of an automotive metal rack is also influenced by decisions made before it enters production. Design must begin with the characteristics of the components to be handled and the expected operating conditions, taking into account the size and weight of the parts, required load capacity, number of parts per rack, loading and unloading methods, manual or automated handling, transport and storage conditions.

For custom metal racks, these factors make it possible to define the geometry of the structure, the restraint systems and any internal accessories according to the specific application. Careful design therefore not only helps to protect components and keep them correctly positioned, but also ensures that the rack is appropriately dimensioned for the stresses it will be subjected to over repeated cycles of use.

This is particularly important in automated automotive production lines, where dimensional accuracy and repeatability are essential to ensure correct interaction between the rack, the component and the handling systems. Deformation or changes in geometry can affect the correct positioning of parts and interfere with automated operations.

At Ferrero Automotive, this is why we develop each project by starting with an analysis of the customer’s requirements and the component’s 3D model. Through feasibility studies, 3D design and simulation, we can assess the rack configuration in advance and verify its compatibility with both the component and the production process before moving on to series production.

As we have seen, the lifespan of metal racks depends on the conditions in which they are used and managed over time. Even when racks have the same design and construction characteristics, differences in frequency of use, handling practices and environmental conditions can result in very different levels of wear. The main factors to consider include:

• type and intensity of use: the number of loading, unloading, handling and transport cycles affects the stresses placed on the structure. A rack that is used frequently or to handle particularly heavy components will generally be subjected to greater stresses than one used less intensively. Keeping within the load limits and operating conditions defined at the design stage is also essential to preserving its characteristics over time.
• Handling practices: operations involving forklift trucks, automated systems or other handling equipment can affect the integrity of the rack. Impacts, incorrect positioning or improper handling can cause deformation and localised damage which, if repeated, may gradually affect structural and functional elements.
• Storage conditions: where and how racks are stored when not in use can affect their condition over time. Prolonged exposure to moisture, weather or particularly harsh environments can lead to surface deterioration and corrosion. Racks must also be stacked in accordance with their design specifications to avoid stresses that their structure was not designed to withstand.
• Cleaning: the frequency and method of cleaning can also affect the condition of the rack. Cleaning products, temperatures and procedures must be compatible with the materials, surface treatments and any internal components. Unsuitable cleaning methods can contribute to the deterioration of surfaces or individual components.
• Maintenance and regular inspections: identifying deformation, wear, corrosion or damage at an early stage makes it possible to take action before these issues affect the rack’s functionality or spread to other parts of the structure. Proper maintenance of automotive metal racks therefore helps to preserve their functional characteristics over time and allows repairs or other work on affected areas to be planned when required.

Regular maintenance of automotive metal racks is essential for identifying signs of wear or damage at an early stage and ensuring that each rack continues to meet the requirements for its intended use over time. Inspection intervals should be determined according to the type of rack, how intensively it is used and the conditions in which it is handled, transported and stored.

Inspections should first focus on the integrity of the structure and welds, particularly in areas subject to greater stress, as well as checking for any deformation, corrosion or other signs of damage. Internal elements designed to position and secure components should also be inspected, together with the correct operation of any moving parts.

Particular attention should be paid to metal racks with stacker pillars used on automated production lines, where the rack’s dimensions, geometry and positioning points must remain within the original design specifications to ensure that robots and handling systems can operate correctly. Deformation or misalignment can interfere with the positioning of the rack or its components and, as a result, disrupt the operations it is designed to support.

Maintenance is therefore about more than repairing damage once it becomes apparent. Regularly inspecting metal racks makes it possible to identify potential issues at an early stage and assess what action is needed to maintain their functionality and efficiency over time. When damaged or worn elements are identified, it can then be determined whether a targeted repair is sufficient or more extensive work is required.

A worn component or localised damage does not necessarily mean that the entire rack needs to be replaced. If the overall structure remains in suitable condition, metal rack repairs can target the affected areas and restore the characteristics required for the rack to continue operating correctly.

Before carrying out any repair, however, it is essential to assess the type and extent of the damage, identify its possible causes and determine which parts of the rack have been affected. Repairs may involve, for example, structural elements, welds, supports, restraint systems or other components subject to wear. Whether a repair is appropriate should be assessed against the rack’s original specifications and the conditions in which it will continue to be used.

The aim is not simply to repair visible damage, but to ensure that, once the work has been completed, the rack still meets the functional and dimensional requirements of its application. This is particularly important on automated production lines, where even changes in geometry or in the positioning of internal elements can interfere with handling operations and the correct positioning of components within the rack.

Targeted repairs to damaged areas can therefore help extend the rack’s service life, avoiding complete replacement when this is not necessary. If, on the other hand, the condition of the rack or new production requirements call for more substantial changes, refurbishment may be a more appropriate option.

The end of the project for which a metal rack was originally designed does not necessarily mean the end of its useful life. If the structure is still in good condition and suitable for further use, refurbishment or modification can be considered, either to keep the rack in service or to adapt it to the requirements of a new production process.

Before any work is carried out, the existing rack needs to be carefully assessed, checking its structural integrity, geometry, dimensions and construction characteristics against the requirements of its new intended use. Feasibility depends both on the condition of the rack itself and on the requirements of the new component and the production process in which it will be used.

Modifications to metal racks may involve, for example, reconfiguring the internal elements used to position and secure components. Where the main structure can be retained, these internal elements can be redesigned and adapted to the geometry and characteristics of the new components, ensuring that the rack continues to meet the functional and dimensional requirements of its new application.

In other cases, more extensive refurbishment may be required to restore the rack to a suitable functional condition and make it fit for its intended use. The decision whether to reuse, modify or replace a rack should therefore be made on a case-by-case basis, following a technical assessment of its condition and whether it can be safely and effectively reused.

Where technically feasible, retaining an existing structure can extend its useful life and reduce the need to manufacture an entirely new rack, limiting the use of new materials and the manufacturing processes involved. In this way, modifying and refurbishing existing equipment can become part of a more efficient approach to managing a fleet of metal racks over the long term.

The process begins with the 3D model of the component provided by the customer, which is used to carry out feasibility studies and virtual simulations. The design is then developed through to prototype production and validation, before moving on to pre-series and series production. For racks intended for automated production facilities, dimensional inspections are carried out to verify the accuracy, repeatability and tolerances required for robotic handling.

The lifecycle of a rack can extend well beyond its initial production phase. When production requirements change, or when production of the component or vehicle model for which the rack was originally designed comes to an end, we assess whether the rack can be reused and adapted for a new application. Depending on the condition of the structure and the requirements of the new application, we can determine the modifications needed and, for more substantial changes, assess their structural feasibility in advance.

The ability to modify existing equipment is therefore part of an approach that considers the rack beyond its original application. Where technically feasible, our custom metal rack modification services allow existing structures to be reused and adapted to new production requirements, avoiding the need to manufacture new racks when replacement is not necessary.
