Automation is now a key factor for any company working with metallisation systems in demanding industrial environments. Cosmetic, beverage, pharmaceutical and automotive brands expect flawless finishes, short lead times and competitive costs. To deliver on all three, manufacturers need coating and high-vacuum metallisation lines that are not only technically advanced, but also designed around smart automation strategies that reduce manual handling and keep every process under tight control.
In this scenario, Tapematic focuses on integrating coating, metallisation and handling into unified, automated solutions capable of supporting mass production without sacrificing flexibility or quality. Instead of treating each phase as a separate island, the entire flow is engineered as one continuous, repeatable process.

PST Line II as the backbone of automated metallisation

At the heart of this approach is PST Line II, a modular in-line system developed to manage every step of the coating and metallisation sequence. Components are loaded onto standardized trays and moved automatically through cleaning, pre-treatment, UV coating, curing and high-vacuum metallisation. The tray concept keeps each part stable and correctly positioned, from the first to the last station, reducing the risk of defects linked to misalignment or manual handling.
While PST Line I marked an important milestone in the company’s development, PST Line II is now the core platform for high-performance installations. For manufacturers who need similar capabilities in a more compact layout, PST Line C offers the same functional logic as PST Line II in a single, non-modular machine, ideal when floor space and initial investment must be optimized. In all cases, Tapematic integrates a dedicated cleaning and pre-treatment module, allowing customers to adapt the installation to their own plant and environmental controls.

Smart handling: the role of trays, robotics and in-line flow

One of the most effective automation strategies in metallisation systems is to standardize how parts are handled. By using dedicated trays designed for specific components, Tapematic ensures that each item maintains the same orientation and position as it moves through the line. This stabilizes the process and helps keep deposition parameters, coating thickness and visual appearance under control.
Automated loading and unloading stations, as well as integration with robots or upstream and downstream equipment, further reduce manual intervention. Parts can be transferred directly from moulding, printing or assembly lines to coating and metallisation and then back into packaging or inspection areas. This continuous flow lowers the risk of contamination, limits bottlenecks and makes production planning more predictable.

Process integration to minimize variables and errors

Another key strategy is to integrate multiple process steps within the same controlled environment. Instead of moving parts between separate machines for base coat, metallisation and topcoat, an in-line architecture combines these phases in a synchronized sequence. This shortens the time between layers, reduces the possibility of dust or handling damage and ensures that each part receives the same treatment profile.
For high-value applications such as cosmetic packaging, pharmaceutical components or automotive parts, this level of integration is critical. It allows manufacturers to achieve premium decorative effects and functional coatings — such as improved barrier properties or mechanical resistance — while maintaining the repeatability needed for large production batches.

Monitoring key parameters for stable metallisation performance

Advanced automation is also about monitoring and controlling the right parameters inside the metallisation system. In high-vacuum environments, factors such as pressure stability, power supplied to the sputtering cathodes, target condition, line speed and temperature all influence the final result. An automated line provides real-time control over these variables, reacting quickly if values deviate from the defined process window.
Combined with data logging and traceability, this enables continuous improvement. Engineers can analyze trends, correlate process parameters with visual or functional outcomes and refine recipes over time. The result is a more robust process that maintains quality across long runs and different product families, even when production volumes increase or designs become more complex.

Balancing flexibility, productivity and sustainability

Finally, automation strategies in metallisation systems must balance three essential requirements: flexibility, productivity and sustainability. Modular architectures like PST Line II allow manufacturers to configure the line according to their needs, adding or reconfiguring stations when product portfolios evolve. High-throughput handling and efficient vacuum management support competitive cycle times and high output.
At the same time, precise application of UV coatings and optimized metallisation cycles help reduce overspray, energy consumption and material waste. By combining these elements, Tapematic’s automated systems support a more sustainable approach to surface finishing — one where premium visual quality, process efficiency and environmental responsibility reinforce each other instead of being in conflict.
In industrial environments where downtime is expensive and product specifications are increasingly demanding, such automation strategies make the difference between a simple metallisation machine and a fully optimized production solution ready for the next generation of packaging components.
