Ultrasonic rotary welding machine for continues welding Filter element

Filters Ultrasonic welding: in the ultrasonics industry, filtration is the treatment of materials used to make objects that filtrate air, liquids or dust.

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.

RPS-SONIC 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.

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.

Rps-sonic supply high power rotary ultrasonic systems to the packaging, hygiene and specialty      converting industries.

Within the hygiene industry, Ultrasonic is used for adult and baby diapers/pant, surgical wrap, and medical face mask products for bonding, attachment, embossing and lamination of thermoplastic materials. The company has engineered solutions for feature attachment, core bonding, acquisition layers and backsheets.

Rps-sonic is also capable and willing to develop comprehensive and customized ultrasonic processing solutions that consider key parameters such as horn metallurgy, acoustic designs and geometries, component fabrication and system engineering in order to meet the processing needs of the customer.
