4a manufacturing
The 4a manufacturing GmbH is a company specialized in the production of thin sandwich composites (0.5 - 3 mm of total thickness) for light-weight applications. The company relies on its wide range of experience in combining the use of metals, plastic and fibre-reinforced polymers to produce the best material for all customer requirements.
Technologies and competences
The company's core competence is the ability to process commercial available foam blocks in a high efficient way, to produce thin foam sheets very cost-efficiently. Combining these foils with the appropriate skin materials, it is possible to create sandwich materials with different properties like high stiffness/weight, high temperature resistance, formability, high damping and FST compliance.
