Filters Ultrasonic Welding
Filters Ultrasonic welding: in the ultrasonics industry, filtration is the treatment of materials used to make objects that filtrate air, liquids or dust.
One of the industries where ultrasonic equipment is most widespread is filters manufacturing. They are usually composed out of finely hatched polyamide fabrics capable to filtrate at a micrometric level, commonly adopted in the biomedical field.
Uses of filters ultrasonic welding
Usually, ultrasonic technology is employed in pleated filters, made mostly out of thermoplastic materials such as polypropylene or those lacking silicon treatments and handled to create filtering tubes of various sizes according to usage.
Filters’ size determine the choice of the sonotrodes frequency that will be needed in ultrasonic machinery.
Sonic Italia proposes a varied series of manual, semi or fully automated welding systems specialized in filters production.
They can integrate electronically controlled rotative (electric rotary tables) or linear solutions with brushless motors.
All of Sonic Italia’s ultrasonic applications developed by Sonic Italiacan be applied in clean rooms with or without soundproofing.
Advantages of filters ultrasonic knitting methods
By applying ultrasound technology it is possible to get steady, reliable results. These factors are a guarantee of using this cutting and searing process.
In addition, materials are not subjected to plastification stress of the welded areas during step by step ultrasonic welding operations.
Seam welding on the other hand, grants a linear and homogeneous outcome along the entire working path while speed is determined by fabrics’ thickness and GSM and the welding surface area.
Both welding processes imply an extremely low energy consumption.
Industrial applications of ultrasonic-welded filters
With ultrasonic technology it is possible to weld many different products, such as the following:
- Single and multi-layered pleated filters;
- Bag filters;
- Plastic ring soldering on tube-shaped filters;
- Air-oil filters ;
- Filtering nets/fabrics;
- Welding tubular filters;
- Outer plastic protection for oil filters;
