Cugher is a global reference point in industrial automation for the flat glass processing sector. The company designs, manufactures, and integrates complete solutions for the handling, screen printing, and quality control of flat glass, with established expertise in the automotive, home appliance, architectural, and solar industries.
Each system developed by Cugher is the result of a highly engineering-driven approach, tailored to the specific production needs of each customer, combining mechanical precision with advanced software solutions. At Cugher, testing is not considered a final phase, but a strategic part of the development process. It is a structured methodology that follows each machine from the beginning of assembly to full operation at the customer’s facility.
The Cugher testing method is divided into three clearly defined phases, each designed to ensure performance, safety, and complete customer satisfaction. Each phase is defined in advance and included in a planner shared with the customer, with clear and agreed-upon timelines, in order to ensure on-time delivery perfectly aligned with production needs
PHASE 1: Internal Testing – Designing with Confidence
Before a machine reaches the customer, it must first meet specific internal technical requirements.
For this reason, the first test takes place directly at the Cugher facility, at the end of the assembly phase, where each system is verified under conditions that faithfully replicate the real production environment.
During this phase, each machine undergoes a thorough inspection across multiple aspects. First, the mechanical functionality is checked, evaluating the precision of movements, structural robustness, and correct assembly. At the same time, the software is tested by simulating various scenarios to ensure that the logic of the programs responds reliably.
Great attention is also dedicated to electrical and safety checks, examining wiring, protection systems, and emergency circuits/logics. The technicians also handle the verification of communication protocols, both in terms of interfacing with machines from other suppliers located upstream and downstream of the Cugher system, and by simulating the machine’s integration with the customer’s networks to ensure full compatibility.
Finally, the testing phase focuses on identifying and resolving any potential issues before shipment. This approach makes it possible to present the customer with a technically reliable system that is ready to go into production.
PHASE 2: Factory Acceptance Test – Validating in Collaboration
Once the internal testing is complete, the process moves on to the Factory Acceptance Test (FAT), which takes place at Cugher’s production site and actively involves the customer. Cugher believes in complete transparency, which is why this step represents a key moment of collaboration, where both parties jointly validate the developed solution.
During the FAT, comprehensive tests are carried out using real samples provided by the customer, in order to evaluate the machine’s behavior under conditions as close as possible to actual production. Every functionality—mechanical, electrical, and software—is thoroughly analyzed, with live demonstrations of the operator interface and fine-tuning of parameters according to the agreed specifications.
The process also includes technical Q&A sessions, designed to clarify every operational aspect and directly involve the customer’s operators and maintenance personnel. At the end of all verifications, an official certificate is issued, confirming that the machine fully complies with contractual requirements.
The FAT is therefore not just a formality, but a critical step where trust is built, expectations are aligned, and the validity of the solution is confirmed in a concrete and shared way before installation.
PHASE 3: Site Acceptance Test – Real Conditions, Real Results
After delivery and installation at the customer’s site, the machine enters the Site Acceptance Test (SAT) phase, where it is tested directly on the actual production line.
This is the moment where engineering meets daily operations, as the system integrates with real products, real operators and the customer’s production flow.
On-site activities include final calibration based on actual product characteristics and cycle times, as well as integration with upstream and downstream equipment already in place. A key component of this phase is hands-on training for operators and technical staff, allowing them to become fully familiar with the system.
This is followed by live validation of performance under production conditions, monitoring output, timing and reliability. The SAT concludes with the customer’s official approval, delivery of technical documentation, and activation of post-installation support.
This step is not simply a final check — it marks the beginning of the system’s operational life, immediately transforming it into a productive, optimized asset.
Summary Table
| Phase | Where | Main Focus | Conclusion |
| Internal Testing | Cugher facility | Engineering tests, functional checks, troubleshooting | System is internally validated |
| Customer FAT | Cugher facility | Joint testing with customer, verification of requirements | Solution approved by the customer |
| On-Site SAT | Customer facility | Operational implementation and training | Solution operates as expected |
Why the Cugher Method Works
Thanks to the combination of solid technical expertise, constant customer involvement, and the validation of solutions under real operating conditions, the Cugher method ensures a smooth, structured, and highly qualified integration process.
This approach minimizes unforeseen issues during installation, significantly optimizes commissioning times, and guarantees full compliance with the functional and safety requirements established in the contract—right from the start.
But it’s not just about technical performance: by guiding the customer throughout the entire journey, Cugher aims to empower them with in-depth knowledge of their system, enabling independent, informed, and efficient operation. This is how Cugher lays the foundation for long-term results, operational reliability, and lasting added value.
At Cugher, testing is not a final step, but an integrated guarantee within the process. From internal tests to customer validation, and final confirmation on site—every phase is designed to ensure that the delivered system is ready to perform.
Cugher is committed to delivering quality that is tested, verified, and guaranteed.
