Increasing demands on component functionality and the need for efficient manufacturing processes are keeping multi-component injection molding squarely in the focus of plastics processing. Not all materials can be processed reliably in the desired combination. The new InMould-Plasma process, which is fully integrated into the injection molding process, facilitates more-efficient production and paves the way for completely new material combinations.

InMould-Plasma Streamlines the 2-Component Process and Expands  the Material Spectrum

Plasmatreat Shanghai, a subsidiary of the German Plasmatreat GmbH, will show exciting and new highlights about its Openair-Plasma technology for surface treatment at Chinaplas in Shanghai from April 13 to 16.

Medical Application: When treating catheters with plasma to clean and activate the surface, the use of plasma replaces, for example, chemical treatments such as sodium etching. Therefore, the plasma treatment is more environmentally friendly than other treatment methods

The use of recyclates confronts companies with new requirements in the processing, bonding, printing and labeling of materials and components. Atmospheric plasma technology, in which Plasmatreat GmbH has specialized, has established itself as a key technology: it often makes the use of recycled plastics possible in the first place – and also proves to be the means of choice on the way to more environmentally friendly, more resource-efficient production processes.

When using Openair-Plasma, the plasma jet works in a location-selective manner and follows the component geometry with millimeter precision. During the plasma treatment, very little heat is generated, so that the treated components remain dimensionally stable.

Plasmatreat to Expand Management Board

A newly developed compact µ-wave plasma source was utilized for activating the surfaces of several polymers. A remarkable improvement of the surface adhesion was achieved.

The Plasmatreat Academy gives an overview of reliable and sustainable manufacturing solutions concerning plasma surface treatment.

In the use of Openair-Plasma (left), the plasma beam operates selectively and follows the part geometry. Only very little heat is produced, so that the treated parts remain dimensionally stable. In the case of PlasmaPlus coating (right), specific additives are introduced into the plasma via a special nozzle head. They are excited by the plasma significantly increasing their reactivity.

The exhibitors at K 2022 showed ways and means of achieving special surfaces by injection molding. A small selection.

The material mix of the “rear-end cover” allows backlit elements to be generated with selective light barriers – with no undesirable light scattering.

Eco-Friendly Pretreatment Technology for the Plastics Industry

Openair-Plama surface pretreatment technology enables users to pre-treat the surface of various materials prior to printing, painting, bonding or sealing.

Plasmatreat´s Openair-Plama surface pretreatment technology enables users to pre-treat the surface of various materials prior to printing, painting, bonding or sealing. Openair-Plama surface pretreatment enables users to pre-treat the surface of various materials prior to printing, painting, bonding or sealing.

When plastic surfaces are activated with Openair-Plasma, reactive species are introduced into the surface structure and the surface properties change – from hydrophobic to hydrophilic. The surface energy, and therefore the wettability, of previously non-polar plastics increases. Inks, lacquers, adhesives or sealants now adhere optimally to the surface without the need for environmentally harmful adhesion promoters.

Plasma also makes completely new materials and material combinations suitable for industrial use, makes processes more efficient and allows previously incompatible materials to be processed together.

Whether large-area treatment of e.g. instrument dashboards in the automotive sector, full-area treatment of e.g. flat lightweight panels, selective treatment of e.g. adhesive grooves or the treatment of electronic components before they are overmoulded with plastic – visitors can experience this and much more at Plasmatreat at Fakuma.

When treating large-area components, such as a dashboard, the use of flame treatment can be dispensed with Openair-Plasma technology.
