SHAMROCK POLY , Australia, decides on AFS

Clifford Lobb, operation manger of SHAMROCK POLY Pty Ltd:

After much investigation and consideration Shamrock Poly decided on the AFS AVB-100G Corona station for its treating requirements. We have chosen AFS because we believe they provide quality products that are long lasting. We decided on the AVB-100G system because it provides simple maintenance free operation.
We have found the AVB-100G system to be extremely easy to maintain, simple to set up and provides consistent treatment to all our applications.

 

bpi.films press release

Press Release April 2010

AFS generators - the product of choice for bpi.films

bpi.films, the UK's leading producer of polythene films for food packaging, medical packaging, liquid packaging, and surface protection applications has just completed the installation of a series of AFS corona generators at its manufacturing facility in Sevenoaks, Kent. The company took the decision to replace all of its existing treater generators with AFS generators based on its previous experience of AFS products, when they proved very reliable over an extended period of high volume activity.

Speaking of the recent investment bpi.films' Operations Director, Gary Buchalter, commented: "The technology available with the AFS generators allows us to continuously monitor and record the power output of the generators. This means we can be sure that the treatment is continuous. It also allows us to review the treatment of any previously produced order. As such, there is a very real quality enhancement. He went on: "Technology available with the latest AFS generators makes them more flexible enabling us to run from very low line speeds, which requires very low power, to high line speeds. It is challenging to create a consistent corona at low power output but the AFS products allow us to do so."

The company has found the AFS operation menu structure easy to use and the self diagnostics system informative and helpful. Importantly, the early-warning system reduces the probability of a production loss by providing the operator with advance information whilst the system is running.

Mr Buchalter continued: The high efficiency levels of the system should allow us to benefit from lower operating costs during the system's lifetime. However, a key factor in our decision to invest in AFS generators was their reliability as this minimises the risk of machine down-time, one of the biggest potential cost factors in the manufacturing process. Additionally we were impressed by the excellent Customer Service and Support levels."

 

Atmospheric plasma method for the pre-treatment of larger width

With the help of electrically generated plasma, non-polar plastics surfaces can be activated before printing or metallic surfaces cleaned before coating.
In contrast to corona treatment, where the materialto be treated is located directly in the electrode’s slot, the indirect plasma method works with an open plasma flame. If air is used as process gas, the width of the plasma flame, and therefore also the width of the treated web, is limited to max. 10mm.
Until now, laminar treatment with this technology meant an immense mechanical and financial effort because a multitude of these relatively complex plasma jets had to be arranged parallel.
AFS Entwicklungs+Vertriebs GmbH presents PlasMatrix, a new development where, instead of five, up to 300 plasma generators can be operated by only one generator. Due to the small and compact construction the nozzles can be arranged in several rows as an overlapping matrix. This enables a homogenous treatment also for larger widths.
The new method is suitable for the treatment of conductive as well as non-conductive web materials, 3D objects, tubes and thick substrates. Because the plasma beam is potentialfree, the application can also be used for the treatment or cleaning of metals in electromagnetically sensitive applications such as RFID or magnetic stripes.
PlasMatrix can be easily integrated into existing lines because there is no need for external power supply apart from electrical energy. The use of air as process gas makes costly and toxic chemicals for surface cleaning redundant.
