Automation is key to industrial innovation and keeping up with, if not anticipating, the needs of the industry, and BG Plast has always been a key player in integrating cutting-edge technologies into extrusion and calendering lines.
With decades of experience in designing and manufacturing thermoplastic sheet and foil systems, we leverage automation to improve accuracy, minimize scrap and maximize operational efficiency.
Automation enables better control in extrusion and calendering operations
Automation: the heart of modern extrusion
Automation in extrusion and calendering processes refers to the use of advanced technologies to control and optimize every stage of production, from raw material feeding to stacking and packaging of finished products. For BG Plast, automation is not simply an add-on or accessory, but is deeply integrated into the design of our machinery to ensure consistent quality, reduce manual intervention, and enable customization.
The main benefits of automation in BG Plast’s extrusion and calendering lines include:
– Increased production accuracy.
– Reduced scrap through more accurate material management.
– Increased scalability to meet different project needs.
– Reduced operating costs due to efficiency improvements.
Automated materials management: ensuring efficiency from the start
BG Plast’s extrusion line automation journey begins with material preparation. Advanced gravimetric dosing systems are used to ensure consistent and accurate feeding of raw materials, whether virgin polymers, recycled flakes or custom formulations. These systems synchronize perfectly with extrusion screws and melt pumps, ensuring consistent production and material homogeneity.
For applications such as PET recycling, where material properties are critical, automated systems ensure that processes such as degassing and contamination removal are performed with unparalleled accuracy. The highest level of control eliminates variability and ensures that the foils produced meet the most stringent industry standards.
Precision control in extrusion and calendering
BG Plast extrusion lines are equipped with innovative automation systems that regulate key parameters such as temperature, pressure and cylinder speed. This level of accuracy is critical for applications where thickness uniformity and surface quality are crucial.
Key features of automated extrusion systems
– Real-time monitoring: sensors and control systems provide real-time feedback, allowing immediate adjustments to maintain optimal extrusion conditions.
– Cross-axis calendering: for the production of thin foils, automation allows the geometry of the cylinders to be adjusted in the cross-axis to ensure uniform thickness for even the most delicate materials (cross-axis).
– Independent motorized cylinders: in calendering systems, each cylinder has an independent drive mechanism controlled by automation to eliminate vibration and ensure smooth leaf formation.
These are particularly advantageous features for the production of optical-quality sheets, such as those made of PC or PMMA, where surface perfection is essential for applications such as skylights and light domes.
In PET recycling, automation ensures better handling of incoming materials
Post-production automation: stacking and packaging
One of the most widely used automation technologies in our lines is the automated stacking and packaging system. After foils and sheets have been calendered and cut to size, automated pick-and-place units handle stacking with speed and accuracy. This reduces manual labor, minimizes the risk of scratches or surface defects, and ensures that sheets and foils are ready for shipment or further processing.
Post-production automation is especially important for large-scale projects, such as the production of PVC roofing membranes or polycarbonate hollow profile sheets. By simplifying and automating these operations, BG Plast helps customers increase production without compromising quality.
Application-specific automation contributions
Automation in BG Plast’s extrusion lines is customized to meet the specific requirements of various industries and applications. Let’s see how automation brings benefits to different extrusion lines.
1. PET recycling lines
For PET recycling, automation addresses the complexities of processing post-consumer materials. Automated systems manage the degassing, filtering, and melting stages with great precision, ensuring that recycled PET flakes are transformed into high-quality foils suitable for packaging and thermoforming.
2. Lines for multilayer foils
In the production of multilayer foils, automation ensures the perfect layering of materials such as EVOH, PE and adhesives. Advanced controls synchronize up to seven extruders for production, maintaining perfect integration and uniform sheet properties. This is especially important for barrier sheets used in food and pharmaceutical packaging.
3. Lines of roof waterproofing membranes.
Roof waterproofing membranes require uniform thickness, UV resistance and significant mechanical properties. BG Plast’s automated calendering systems, combined with in-line compounding technologies, ensure that membranes meet the stringent requirements of the construction industry while maintaining high productivity.
4. Optical-quality sheets
The production of optical-quality sheets requires close control of thickness, brightness and transparency. Automated systems on our lines ensure vibration-free cylinder movement and scrupulous application of the UV layer, which is essential for skylights, door glass and lighting covers.
The future of automation in extrusion
BG Plast continues to innovate by focusing on integrating innovative technologies such as AI-based analytics, IoT connectivity and predictive maintenance into extrusion and calendering lines. These improvements will enable greater efficiency by identifying potential problems before they can cause downtime and optimizing production parameters in real time.
Also considering how sustainability is a key objective, automation will play a key role in improving the energy efficiency of extrusion processes. From reducing material waste to optimizing energy consumption, our commitment to automated solutions ensures that our machinery is always at the forefront of both technology and environmental responsibility.
In optical-quality sheet extrusion lines, automation also contributes to an optimal result from an aesthetic point of view
