The SIGNA TB is a modern High Frequency (HF) welding press engineered for demanding serial production with a focus on maximizing throughput per square meter of floor space. SIGNA TB are perfect machines for serial production of orthosis, rehabilitation equipment, medical containers like blood or ostomy bags, as well as automotive parts and assemblies, embossing, clam shell plastic packaging, etc.
The SIGNA TB features a unique Dual-Table Design—a compact, vertical arrangement often referred to as a “Pater Noster” configuration. This design incorporates two automatic, pneumatically driven shuttle work tables, stacked one above the other, on a single side of the machine.
The SIGNA TB series is engineered for maximum operational flexibility and superior weld quality across diverse materials and applications.
This High Frequency (HF) welder is designed for universal application, ensuring high performance even with challenging polymers:
Precision and repeatability are managed by a state-of-the-art digital control system:
The comprehensive suite of options, settings, and integrated safety features position the SIGNA TB as the perfect tool for high-end manufacturing where precision, durability, and strength are paramount to product success.
Full diagnostic testing and certification of the local factory EMC/EMS parameters according to the latest guidelines required by the CE & UL standards. We have our own ISO 17025 certified production control and EMC laboratory providing validation of each required process parameters and the whole technological production cycle.
High frequency welders manufactured by Zemat Technology Group are designed and built in accordance with current European requirements for machine safety and energy efficiency. The machine design incorporates technical solutions that enhance welding process stability, reduce energy losses, and increase production repeatability.
HF Smart Control™ is a set of structural and electronic solutions implemented in high frequency welders, including:
The HF/RH welders use high frequency generators with microprocessor-based power control, enabling precise adjustment of energy to the process parameters. The system continuously monitors operating conditions and dynamically regulates power in real time. As a result, energy consumption can be reduced compared to heat sealing technologies and many impulse-based systems. The actual level of savings depends on the material, application, and process settings.
The ATS ensures precise impedance matching and automatic generator tuning during machine operation. This stabilizes the welding process, reduces the risk of instability, and minimizes the possibility of arcing. Fast reflected power control protects HF circuit components and improves weld repeatability.
Modern HF generators achieve energy efficiency levels of approximately 70–90%, depending on configuration and operating conditions. Band-pass filters reduce harmonic distortion, while lower thermal losses decrease heating of machine components. This results in stable operation and extended service life of key components.
