Regular maintenance is essential to keep any equipment in perfect working order. For a glass tempering furnace, which is subjected to high thermal stress daily, regular checks are vital for ensuring optimal performance and a long lifespan.
If you have invested in a high-quality, long-lasting furnace, regular maintenance is what will enable it to support you in your work for decades.
Why is maintenance so important?
Good maintenance ensures:
- uniform heating,
- consistent quality of tempered glass,
- safety for operators,
- longer system life.
To achieve this, it is useful to plan daily, weekly and monthly checks, as well as more thorough inspections at regular intervals. Many of these activities can be carried out directly by operators and performing them consistently minimises the risk of machine downtime.
Daily checks:
Every day, it is important to:
- Keep the furnace clean by removing dust and residues.
- Check the ceramic rollers and internal surfaces.
- Check operating parameters (temperature, pressure and ventilation).
- Pay attention to any warning lights or alarms. Often, the manufacturer can intervene remotely to quickly resolve minor problems.
Weekly checks:
At longer intervals, it is necessary to:
- Keep electrical panels clean and ventilated.
- Check and replace air filters if necessary.
Monthly checks:
Every month (or every few months), it is recommended to:
- Thoroughly clean the ceramic rollers.
- Check the cooling section and remove any residues.
- Check that the heating chamber is clean and, if necessary, remove any remaining glass residue.
Annual checks:
- Lubricate gearboxes, motors and bearings according to the manufacturer’s instructions.
Additional tips for maintaining the efficiency of your oven
- Document every intervention, including the date, operators and activities carried out, as well as any anomalies found.
- Assign clear responsibilities for each check: if it is not clear who is responsible for what, checks are likely to be skipped.
- Raise awareness among operators during the installation phase.
- Increase the frequency of inspections in dusty or particularly harsh environments.
- Seal the furnace in case of prolonged downtime, and perform a complete check before restarting.
In order to require low maintenance, what should a glass tempering furnace be like?
A furnace designed to require little maintenance must:
- be constructed of high-quality materials,
- ensure uniform and accurate temperature control,
- have robust mechanical, electrical and electronic components,
- use efficient and adjustable cooling systems,
- integrate intelligent remote control and monitoring systems.
The Mazzaroppi approach
At Mazzaroppi, we design and manufacture energy-efficient, long-lasting glass tempering furnaces. We use only the highest quality European materials and provide continuous assistance, both remotely and on site.
During installation:
- we train operators on how to use the machinery and on maintenance procedures;
- we set up production recipes;
- we demonstrate all the necessary operations for smooth and safe use;
- we remain in constant contact, both remotely and in person, to assist with any requirements.
We also carry out regular and ad hoc maintenance, as well as upgrading and revamping our systems for those who wish to improve performance after decades of operation.
