Technical welding Welding is a fundamental process in many industrial sectors. It involves joining materials, particularly plastic films, using various fusion techniques to create robust and durable structures. Technical welding plays a crucial role in the manufacture of complex products (such as medical bags, water bags, inflatable products, and airbags). Mastering it requires not only technical expertise but also a deep understanding of the materials and methods to be applied for each specific project.
Industrial Welding Processes at Manudo Group
At Manudo Group, we master a variety of welding processes to meet the diverse needs of our clients. Thermal welding It uses electric currents to generate heat and melt materials. A resistor is heated to a high temperature (Vicat point, meaning the material becomes soft). Then, the temperature is raised to the material’s melting point.
We also use high-frequency welding. This process requires the application of electromagnetic fields to heat and weld thermoplastics.
Each method is designed to deliver precise and reliable results, tailored to various industrial applications. The choice of method depends on the client’s project, their desired outcome, and also on the materials used.
We also offer thermoforming. which uses heat to soften the material in order to give it a particular shape. This allows for the design and production of molds of different shapes and sizes for various applications.

The Materials We Use
The choice of materials is crucial for the quality of the welds. At At Manudo Group, we select our materials according to your final requirements and taking into account specific properties, in order to guarantee the reliability and performance of the assemblies produced. There are several types of thermoplastic polymers. such as polypropylene, polyurethane, EVA, PVC, and complex films. They are chosen for their flexibility and their ability to withstand mechanical and environmental stresses.
