This informative article by Telsonic’s Martin Frost, looks at the different types of filter media, their applications, and discusses how ultrasonic welding, cutting, and sealing processes have become a key part in the production of different filter types.
The Cut’n’Seal process uses ultrasonic energy to cut or punch out a range of thermoplastic and synthetic type materials, whilst at the same time sealing the edges.
When, in the Spring of 2020, the full effects of COVID-19 took hold globally, the quest to source and make available suffcient quantities of PPE and Face Masks began in earnest in the UK.
Respiratory masks protect against fine dust, smoke or aerosols and, depending on the design, also provide protection against bacterial and viral droplet infections, such as those caused by the coronavirus SARS-CoV-2. The commercially available, particle-filtering, folded or molded masksare divided into different protection classes that define the structure of their filter materials.
As the fight against COVID-19 intensifies around the world the use of face masks has become mandatory within many everyday environments. Although the wide range of standard mask types commonly used today do provide protection for both the wearer and those in the immediate vicinity, a new report, published in the Lancet journal, found the Coronavirus is capable of surviving on the outside of a face mask for 7 days.
Ever since the COVID-19 pandemic started to take hold around the world,there has been a serious shortfall in the availability of face masks. However, Korean-based HJ PNC began manufacturing fully automated mask production machines in March to tackle this issue head on.
