The adoption of advanced technologies, collaboration with suppliers, and continuous improvement practices contribute to a comprehensive proactive maintenance strategy, resulting in prolonged die and mould lifespan, minimised downtime, and ultimately, cost savings for manufacturers.
Factors that affect the lifespan of dies and moulds
The lifespan of dies and moulds in manufacturing is often impacted by a range of common challenges and issues that manufacturers need to address proactively. Three primary factors that significantly affect the durability of dies and moulds are:
- Wear and tear: This refers to the gradual deterioration of dies and moulds over time due to repeated use, friction, and mechanical stress during the manufacturing processes. Continuous use without proper maintenance can lead to abrasion, surface damage, and dimensional changes, compromising the precision of the components produced.
- Corrosion: Corrosion is the chemical reaction between the surface of the dies and moulds and the surrounding environment, often accelerated by exposure to moisture, chemicals, or contaminants. Corrosion can result in pitting, surface irregularities, and degradation of material properties, leading to reduced functionality and structural integrity.
- Thermal fatigue: This occurs when dies and moulds undergo cyclic temperature variations, causing expansion and contraction that lead to material fatigue over time. This phenomenon can result in cracking, warping, or premature failure, particularly in areas subjected to rapid heating and cooling cycles during manufacturing processes.
Some maintenance tips
Addressing these challenges requires a combination of proactive measures, including regular inspections, preventive maintenance, proper cleaning, and the use of high-quality materials. Implementing temperature control measures, selecting corrosion-resistant materials, and employing effective lubrication and cooling strategies can further mitigate the impact of wear, corrosion, and thermal fatigue, ultimately extending the lifespan of dies and moulds and ensuring the production of high-quality components. Here are some key points, which will help in extending the lifespan of dies and moulds:
