A deflector is an aerodynamic component designed to optimize airflow around the vehicle, helping to reduce drag, noise, and overall energy consumption during operation. In this particular application, the deflector also serves as a cover for the battery module located behind the driver’s cabin. In addition to its aerodynamic function, the part must therefore meet demanding requirements for strength, dimensional stability, and long-term durability.
“During development, we designed a material solution meeting the high requirements for strength and dimensional stability of the deflector.
The resulting part improves the aerodynamics of the tractor unit with the battery module located behind the cab.“
The robotic bonding workstation ensures maximum precision, consistency, and joint quality through a fully automated process with continuous monitoring of all key parameters. This enables repeatable and reliable results even for large and technically demanding components.
„We follow industry trends and actively seek development opportunities in new challenges.
The breadth of our technological portfolio often surprises even our customers.”
A Wide Portfolio of Technologies Under One Roof
From RIM, SMC, and vacuum forming to finishing operations such as grinding, painting, assembly, and advanced logistics – this is Promens Zlín.
We supported the customer’s development team from the very first prototypes, working jointly to identify the optimal technical solution. By implementing robotic bonding, we met the customer’s stringent requirements and ensured the required quality we can fully stand behind.
„We are involved in all phases of product development.
With electrification in automotive, we already have valuable experience that gives us a strong advantage and perspective.“
The robotic station performs plasma treatment of the bonding surface, ensuring optimal conditions for adhesive application. Continuous quality control and automated evaluation of each step guarantee process reliability and repeatability.
The robotic arm is equipped with interchangeable heads for both plasma treatment and adhesive application. This flexibility, combined with high precision, enables efficient processing of large-format parts such as this side panel for electric tractors.
Deflector Assembly
The assembled deflectors, fitted with stainless-steel brackets, are subsequently packaged and shipped to customer-approved external paint shops. Assembly, including bracket installation, represents the final stage of the process.
The final assembly of the deflector, including the installation of stainless steel brackets, is the final stage of the entire process. The finished parts are then packed and shipped to external paint shops certified by the customer.
“The truck segment is very important to us. However, customers from other industries can also benefit from the new bonding line, as the robotic workstation can be reprogrammed and used across segments.
Thanks to automation, we can process orders even more efficiently and at lower production costs.”
Logistic map for e-truck parts: From Promens Zlín, the deflectors travel to external certified paint shops, from where they continue to Gothenburg, Sweden – the place of final assembly of the e-trucks.
Electrification in freight transport is an important milestone — but certainly not the final destination. Thanks to robotic bonding, we are ready for further technological innovations on the path to a zero-emission future.
