In the PET bottle blow molding sector, energy efficiency has become a strategic priority. Rising energy costs and the push toward more sustainable production are driving manufacturers to optimize every stage of the process. In this context, Competek offers a solution that acts at the very core of blow molding technology: Supervent Technology, an advanced ventilation system integrated into the mold, designed to maximize performance and reduce energy consumption.
Optimizing Airflow Inside the Mold
Supervent Technology introduces an innovative engineering approach to air management during the blowing phase. Thanks to an optimized design of the ventilation channels between the mold cavity and the expanding preform, residual air is evacuated more quickly and efficiently. This allows the desired shape to be achieved with lower blowing pressures, directly reducing the consumption of compressed air-one of the main sources of energy expenditure in PET production plants.
Energy Savings and Process Stability
Lower blowing pressure translates into significant energy savings, especially on high-output lines. But the benefits go beyond consumption: faster air evacuation improves process repeatability, widens the operating window, and ensures greater production stability. The result is superior container quality, with more precise geometries, sharper textures, and fewer rejects or machine stoppages.
Proven Field Performance
A recent project carried out by Competek in India confirmed the effectiveness of the technology. Among six blow molding machine models and 86 molds supplied, 47 were equipped with Supervent Technology. The adoption of the system led to a noticeable reduction in operating pressures, with a direct impact on energy consumption and overall line efficiency.
Invisible Technology, Tangible Results
In an industry where sustainability is increasingly measured in terms of production efficiency, Supervent Technology offers a concrete way to reduce operating costs and environmental impact. It’s an “invisible” solution in the finished product, yet capable of delivering measurable advantages in performance, reliability, and energy savings.
