Thanks to our design office, we are a driving force for innovation and proactive approach to all our products, with the aim of satisfying the end consumer.
Manufacturing processes
High-frequency welding
This technique allows different layers or several thermoplastic parts to be assembled using an electromagnetic field.
The heat produced by the emission of a high-frequency field passing through the materials to be welded causes them to melt under pressure from the welding electrodes.
Various materials can be used such as PVC, PU, EVA, etc… The choice of materials is made according to the product in question and the customer’s expectations.
High-frequency welding varies depending on:
- Materials used
- Of the product in question (its dimensions, its shape)
- Due to the complexity of the product (air circuit, tubes)
Thermoforming
This technique involves heating a plastic material in the form of a plate or sheet to soften it using a heating plate and a radiant heater. This softened state allows the material to be taken advantage of and molded into the desired shape using a mold..
Different types of materials can be used, such as PVC, PP, etc…
Thermoforming will depend on:
- The product desired by the customer: its intended final form
- Selected materials
Thermal welding
This technique, based on the same principle as high-frequency welding, will allow the assembly of different layers or several thermoplastic parts.
The main difference lies in the mechanism. In this case, the operation is achieved by heating the welding tools via a resistance element, which then allows the weld to be performed.
We can also find PVC, PU, EVA, etc., among the materials used…
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.
