The Manudo company located in Isère, in the Rhône-Alpes region and more precisely in Montalieu-Vercieu is located on an architectural site labeled HQE (High Environmental Quality).
Manudo is present in 2 business sectors
We are a major player in high-frequency welding, thermal welding, and thermoforming.
His expertise is used in these 2 sectors, respecting the industrial mastery of sealing and meeting the essential requirements on the assembly and welding of the different devices.
The approach is the same for these companies since they offer tailor-made products, through the work of a design office in order to meet the challenges of these clients.
A distribution brand
Dapa Plast is a distribution brand owned by Manudo and present on the French website.
This allows the marketing of thermoplastic coated films and fabrics in rolls for professionals.
Manudo possesses technical expertise on different materials, enabling them to guide and offer tailor-made solutions according to the client’s needs.

At Manudo Group, we are experts in technical welding processes, offering precise and reliable solutions to meet the diverse needs of our industrial clients. Technical welding involves the use of advanced technologies to create complex and robust assemblies, thus guaranteeing the performance and durability of the finished products. Thanks to our expertise, we offer welding processes tailored to the specific requirements of each application.
Types of Welding Techniques
We offer various thermal welding processes to meet specific needs. 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. High-frequency welding It applies electromagnetic fields to heat and weld thermoplastics. Each method is designed to offer precise and reliable results, suitable for different industrial applications. Thermoforming uses heat to soften the material in order to give it a particular shape.
Materials Used in Welding Techniques
Manudo Group’s technical welding processes utilize a variety of materials selected for their specific properties. Thermoplastic polymersMaterials such as polypropylene, polyurethane, EVA, PVC, and many others are used for their flexibility, durability, and strength. The choice of material depends on the client’s application requirements, ensuring reliable and high-performance assemblies that meet the strictest industry standards.
Advantages of Technical Welding Processes
Technical welding processes offer numerous advantages, including high precision, robust assemblies, and flexibility in material selection. By utilizing cutting-edge technologies, we are able to perform complex welds that meet the specific requirements of each project. Mastering several welding techniques, we can adapt to each client’s needs to deliver a product that perfectly meets those requirements. Our processes guarantee durable welds capable of withstanding extreme conditions, thus improving product reliability and longevity. Furthermore, the customization of our welding processes allows us to precisely meet our clients’ needs, ensuring maximum satisfaction.
