Thermoplastic structural foam - A well known and new process

In this process there will be covered the state of the art and the latest development steps of structural foam injection moulding and advantages of the foam structure as well. Processes for the moulding with improved surface quality are covered by means of either has counter pressure or co-injection moulding. The paper also covers the different methods using chemical and physical blowing agents. The process is also new as thin wall foam has become more interesting again using either chemical or physical blowing agents.
