SIGNA is a high-frequency welder designed for a wide range of components requiring precise, repeatable welds and tooling tailored to a specific product.
SIGNA is suitable for both simple components and parts requiring more complex weld shapes. Selecting the electrode, positioning fixture, pressing system and other tooling allows the machine to be adapted to the specific material and product.
The shuttle worktable makes it easier to prepare and accurately position the component before the cycle starts, while the stable workstation structure supports precise and repeatable welding.
PLC control with an HMI touchscreen panel allows process parameters to be controlled and recipes to be saved for different products. This makes proven settings easier to reuse and shortens machine setup during production changeovers.
Depending on its configuration, SIGNA can also feature a heated platen and additional systems supporting process control, safety and fast tooling changes.
Additional machine features
SIGNA can be built in different versions for a specific product and process. Variations include table size, press type, HF generator power, automation level and monitoring systems.

SIGNA is ideal for series production requiring repeatable high-frequency 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.

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 is a high-frequency welder designed for components requiring accurate positioning, controlled pressing force and repeatable process parameters. Applications include medical components, automotive parts, packaging and a wide range of technical products.
SIGNA uses one shuttle worktable, while SIGNA DUO has two tables that allow components to be prepared and welded alternately. The choice depends primarily on process organisation and required production throughput.
SIGNA can process materials suitable for high-frequency welding, including PVC, PU, TPU, PET and selected laminates and foams. Process parameters are selected to suit the material type, thickness, weld area and product construction.
Yes. SIGNA can use electrodes and tools designed for a specific weld shape. This allows both simple linear welds and joints with more complex geometries.
Yes. Dedicated electrodes, positioning fixtures, cutting dies and other tooling can be made for the machine. Tools are selected to suit the component geometry, material type and specific production process requirements.
Yes. The HMI panel with PLC control allows process parameters to be saved for different products. This simplifies production changeovers and enables proven settings to be reused in subsequent production runs.
