Fast Compression in Multiple Layers

The Institute of Plastics Processing (IKV) Investigates the Injection Compression Molding of Thick-Walled Lenses in a Multilayered Structure

Fast Compression in Multiple Layers

Thick-walled plastic optics are usually built up layer by layer in multilayer injection molding, as this significantly shortens the cycle time. In order to improve the quality and further reduce the cycle time, layer thickness ratios were varied at the German research institute and strategies for mold temperature control were developed. In addition, injection compression molding was adjusted to the multilayer process.
