4a manufacturing GmbH

4a manufacturing GmbH is part of the 4a group and is the world leader in the production of “micro-sandwich” materials for the consumer electronic market since more than 10 years. This technology enables innovative lightweight designs for panel or shell constructions, by substituting monolithic materials like metals or fiber composites with thin sandwich materials. Major part for the creation of an innovative sandwich material is the selection of the right core material. 4a manufacturing developed an innovative technology for the production of thin hard foam sheets, called MILLIFOAM®.

MILLIFOAM®
thin hard foam sheets
An important factor for creating a high-performance sandwich material is the choice of the right core layer. The 4a manufacturing product MILLIFOAM® is a very thin hard foam sheet, which can be used as core layer for sandwich materials. These foam sheets are available in different thicknesses (starting at 0.15mm) and are obtained from commercially available polymer grades (PET, PVC, PPE, PMI, PESU,…).

CIMERA®
Core competence of the 4a manufacturing is the design and production of thin sandwich materials, offered by the trademark CIMERA®. The goal of CIMERA® is to reduce the weight of thin components (starting at 0.20mm) made of monolithic materials like steel, aluminum, GFRP or CFRP, by replacing them with a cost-efficient sandwich design.
