Purchasing a glass tempering furnace is a strategic decision that represents a significant milestone for any glassworks or company.
It not only raises your technological level, but also allows you to enter a more competitive market and offer new processes to customers.
For many businesses, it is a significant investment that requires careful consideration to avoid unpleasant surprises and ensure a quick and lasting return on investment. This is why it is important to carry out the necessary assessments before making a purchase.
So, what questions should you ask yourself before buying a glass tempering furnace? Here are the main aspects to consider.
Is building work required?
Many people think that installing a tempering oven inevitably involves invasive structural work, such as adapting the premises or changing the layout of production areas. While this may have been true of older generation ovens, today’s technology has advanced significantly.
A compact and carefully designed furnace, such as Mazzaroppi’s TP Compact, for example, can be installed in confined spaces without the need for building work or a supporting wall. This results in faster installation times, lower costs, and above all, fewer interruptions to ongoing production.
Do I need to rebuild the electrical cabinet?
The installed power is one of the most important factors to consider when purchasing a glass tempering furnace. Many traditional systems, particularly larger ones, require dedicated electrical cabinets and significant upgrades to the internal network. This can result in unexpected expenses and system downtime.
It can take up to a year before your furnace is operational, and this will require considerable additional expenditure.
The solution is to choose a furnace that operates at a low power level without compromising the quality of the tempering process. Thanks to specific, optimised software, it is now possible to limit power consumption peaks.
Mazzaroppi’s patented M Efficiency 5.0 software ensures that glass from 4 to 19 mm can be tempered with only 180 kW installed. This means the system can operate without requiring dedicated electrical cabinets, resulting in significant time and cost savings.
How much does it consume?
Consumption is a variable that directly affects the profitability of the investment. It is not enough to know how much the furnace consumes when it is ‘up and running’; you also need to assess its consumption when it is not producing.
For example, a furnace with a Start&Stop function can be turned off at the end of a shift and back on again in just half an hour. This avoids hidden costs associated with maintaining the temperature during periods of inactivity.
Additionally, an advanced convection management system adapts power consumption to the type of glass and percentage of oven filling, significantly reducing consumption. Meanwhile, rapid thickness change systems enable switching from 4 mm to 19 mm glass without lengthy downtime.
Is it user-friendly?
Unfortunately, the shortage of skilled labour is a widespread problem that cannot be ignored when deciding to purchase new machinery.
Although a tempering furnace is a complex machine, it can be designed to be user-friendly. This involves intuitive interfaces, preset cycles, rapid assistance and the ability to monitor parameters remotely.
A user-friendly furnace reduces operator errors, shortens staff training times, and ensures consistent product quality.
Do you think it’s impossible to find energy efficiency, ease of use and high performance in a single furnace? Fortunately, this is not the case.
Mazzaroppi’s glass tempering solutions are the most energy-efficient on the market. They guarantee energy savings of up to 70% compared to competing furnaces while offering excellent performance and guaranteed ease of use.
We are committed to making tempering accessible and straightforward for glassworks and companies of all sizes, helping even the smallest businesses to grow and optimise their investment.
