Injection-moulded plastic-glass composites DE-PS-76
A German institute specialising in materials has initiated a cooperative project on injection-moulded plastic-glass composites in order to combine the beneficial properties of both materials (e.g. scratch-resistance of glass and design freedom of plastics). Companies from the plastics industry are sought for participation in the project.
The combination of glass and plastic is an ideal composite for technical and decorative products. Glass is extremely scratch-resistant and transparent, and is thus ideal for display and decorative applications. Plastics are characterised by their enormous design freedom and high integration level, formability, low material cost and low specific weight.

A German plastics/materials institute has initiated a cooperative project for elaborating a basis for linking glass and plastics by injection-moulding processes. The aim is to use glass e.g. for display units and implement the fixing for later integration into elements via the corresponding plastics components. The plastic components can have a design or a technical function. The scratch-resistance of glass can therefore be combined with design freedom of plastics in one element.

The combination of this composite can be achieved through different joining technologies. When small numbers of elements are processed, often gluing, foaming or clipping technologies are used. However, when treating large amounts of elements, insert moulding of the glass element can be an option. The advantage of this is that the joining operation is carried out directly during the production process of the plastic element, saving one production step. Moreover, a higher degree of tightness between the components can be reached which could be relevant for external applications. The aim of the project is to investigate the prerequisites of insert-moulding glass with plastics and enable participants to choose the right plastic and glass materials for their processes as well as to provide them with article, process and tool-specific background knowledge according to their needs and specifications.
Innovation and advantages
- Higher tightness between the two components
- Saving one production step
- Higher cost-effectiveness than conventional joining technologies.
Technical specifications
The safe insertion of fragile glass into the injection mould is realized by means of flexible sealing elements in combination with a spring-loaded core. The subsequent insert moulding process is done by means of foamed thermoplastic moulding with variothermal temperature control according to the BFMOLD™ principle to achieve a streak-free high-quality surface.
