A high-frequency welder with two shuttle tables, designed for series production of components requiring accurate positioning, stable pressing force and repeatable process parameters.
SIGNA DUO was designed for series production where accurate material positioning, repeatable pressing force and a smooth operator workflow are important. The machine is suitable for flat products, shaped components and parts requiring more complex weld geometries.
Two shuttle tables allow material or tooling to be prepared outside the welding platen working zone. The operator can load the next component on one table while the machine performs a welding cycle on the other, reducing downtime and helping maintain a consistent production rhythm.
SIGNA DUO can use a pneumatic, hydraulic or servo-electric press. The pressing system is selected to suit the material, weld area, required force and process method.
The head platen is a standard machine component. It can be used with the HeatPLATE™ heating system and QuickGrip™ clamping, which simplify tool changes and workstation preparation for the next product.
Additional machine features
SIGNA DUO is ideal for series production requiring repeatable HF welds, accurate component positioning and tools designed for a specific product.
Zemat high frequency welding machines use systems designed to support operator safety, protect key machine components and maintain process stability. These solutions help protect the electrode, material, generator and work area, while process monitoring systems enable fast detection of irregularities and help maintain repeatable welding parameters.
For machines manufactured by Zemat, mandatory electromagnetic field (EMF) emission measurements are carried out in the working environment. The tests are performed by the Mobilab laboratory operating within Zemat Technology Group. The measurement laboratory works in accordance with ISO/IEC 17025 and holds PCA accreditation, confirming the quality of its services and the reliability of measurement results.
Zemat HF welding machines are designed in accordance with European requirements for machinery safety and energy efficiency. The applied solutions support process stability, reduce energy losses and help maintain repeatable production parameters.
HF Smart Control™ includes:
When purchasing a Zemat machine, customers also gain direct access to the team that knows its design, configuration and welding process. Zemat machines are supported by our own technical service team, so there is no need to rely on third-party providers or explain the machine and process from the beginning.
We support customers during installation and commissioning, train operators and maintenance teams, and provide technical service worldwide. In many cases, issues can also be diagnosed and resolved remotely by checking machine settings, recipes, process parameters or system messages without waiting for an on-site service visit.
Every welding process has different requirements, so the machine configuration is selected according to the specific product, material, component dimensions and planned production conditions.
Tell us what you need to weld and how your process works. Based on this information, we can help select the right machine model, generator power, working area, operating method, tooling and any additional equipment required.
SIGNA DUO is a high-frequency welder with two shuttle tables. It is used for series production of components requiring accurate positioning, repeatable pressing force and welding parameter control.
SIGNA DUO has two shuttle tables that allow the next component to be prepared outside the welding zone. This improves operator workflow and can shorten pauses between cycles.
The machine is ideal for medical products, automotive components, laboratory and rehabilitation equipment, blister packaging, technical products and parts requiring shaped welds.
SIGNA DUO can process materials used in HF welding, including PVC, PU, TPU, PET and selected laminates and foams. Parameter selection depends on the material, thickness and weld area.
Yes. SIGNA DUO can be configured with a pneumatic, hydraulic or servo-electric press. The pressing system is selected to suit the product, material, weld area and process requirements.
HF generator power is matched to the application. Depending on the version and process requirements, SIGNA DUO typically operates with 4–30 kW power.
Yes. The machine can use electrodes and tools designed for a specific weld shape. This makes it suitable for flat and three-dimensional components and products with more complex geometries.
Yes. Electrodes and working components can be made for a specific product. Zemat's in-house tooling department can tailor tools to the component shape, material type and welding process requirements.
Yes. The HMI panel with PLC control allows recipes to be saved for different products. This simplifies production changeovers and helps maintain repeatable settings across subsequent cycles.
Depending on the version, SIGNA DUO can support process data logging, operator access levels and traceability functions. This is particularly important in medical production and other applications requiring quality control.
Yes. Selected versions can be configured for environments with enhanced cleanliness requirements, depending on the product, industry and project requirements.
