At Secomak, we pride ourselves on delivering innovative, practical solutions tailored to our customers’ needs. A recent project with a major American aerospace company is a great example of what we do best, combining engineering expertise with real-world problem solving.
The challenge? Preheating a 450kg aerospace-grade copper component before precision welding. This is a crucial step in the process, as it:
- Prevents cracking by controlling cooling rates and reducing thermal stress
- Minimises residual stress and distortion, helping to ensure a strong and stable weld
- Encourages hydrogen diffusion, which reduces the risk of defects during welding
From 5 Hours to Just 1 Hour — A 400 Percent Improvement
Originally, the heating process took up to five hours, creating a bottleneck in production. Working closely with the customer, our Sales, Engineering and Technical Controls teams designed a bespoke 36kW HeatPack system that brought that down to just one hour. That’s a fourfold improvement in heating efficiency.
This was a carefully engineered solution that prioritised performance, reliability and safety.
What Made the HeatPack the Right Choice
The HeatPack system used in this project was specially adapted for aerospace use, delivering the precision and control needed for such a high-spec application. Some key features of our heatpack included:
- Precision heating with hot air up to 400°C and temperature accuracy within ±1°C, thanks to advanced PID control and a solid-state relay pulsing 1000 times per second• Smart energy use through precise
- temperature control and an optional Variable Speed Drive for airflow regulation, helping to reduce running costs
- Industrial-grade reliability with direct drive blowers and fast-responding heaters built for continuous use without maintenance
- Safety built in, including a high-temperature cut-off, adjustable alarms and the option for an HMI for enhanced control and monitoring
- Recirculation capability to reuse hot air, cutting down energy demand and improving overall efficiency
- Flexible setup, with a full range of accessories and an optional trolley with lockable castors for easier transport and integration on site
What the Customer Had to Say
“Very impressed and thank you all for the support.”
“Wanted to update that the machine has been working terrific.”
Feedback like this reminds us why we do what we do, and how a well-engineered solution can have a real impact on productivity.
