Thermofusion

: Termofusión

Information

Thermofusion is a process for joining thermoplastic materials through the application of heat and pressure. This process involves melting the surfaces of the pieces to be joined so that, upon cooling, they fuse together, forming a solid and homogeneous joint. Here are the steps and key aspects of the thermofusion process:

Surface Preparation: The surfaces of the thermoplastic materials to be joined are cleaned to remove any dirt, grease, or contaminants that could affect the quality of the joint.

Heating: The clean surfaces are heated until they reach the melting temperature of the material. This can be done using various methods, such as electric heaters, heating plates, or internal heating elements.

Application of Pressure: Once the surfaces are melted, pressure is applied to ensure intimate contact between the pieces. This pressure helps the molecules of the molten material to mix and interlace, creating a strong joint.

Cooling: After applying pressure, the pieces are allowed to cool while maintaining the pressure. The cooling must be controlled to ensure that the joint solidifies properly and forms a robust connection.

Verification of the Joint: Once the material has cooled and solidified, a visual inspection can be performed, and in some cases, strength tests to ensure that the joint is adequate and meets technical requirements.

Applications of Thermofusion

Pipes and Fluid Conveyance Systems: Thermofusion is commonly used in the installation of polyethylene (PE), polypropylene (PP), and other thermoplastic pipes, especially in water supply, gas, and sewer systems.

Automotive Industry: In the manufacture of automotive components such as fuel tanks and cooling systems, where a secure and durable joint is required.

Construction and Architecture: In the joining of waterproofing sheets and membranes used in the construction of roofs and other waterproof structures.

Chemical Industry: For the manufacture and repair of containers and tanks used for the storage and transport of corrosive chemicals.

Electronics and Appliances: In the production of housings and components for electronic devices and household appliances.

Thermofusion is an efficient and reliable technique for joining thermoplastic materials, providing a hermetic and resistant joint that is essential in many industrial and commercial applications.
