Advances on Injection Molding of Polymers

Dear Colleagues,

The simplest description of the injection molding process is: molten materials are injected into a cool cavity where they solidify. In reality, the process is very complex. Nevertheless, it allows us to produce finished objects of any geometry by a single shot. For this reason, the injection molding process is very diffuse, and more than 30% of all plastics are processed by injection molding machines. New developments of the process occur continuously in order to favor the production of parts for a particular use and/or realized with special materials. For instance, in the last few decades, standard injection molding was adapted to realize very small parts due to the rapidly growing and evolving demand for micro- and nanostructured devices with a high level of reproducibility at a small cost.

Among the parameters that identify the quality of a part, the dimensional tolerance and stability of moldings are very important and may well run out of control. Furthermore, the moldings’ final properties are related to their bulk and surface morphology distributions, which in turn are determined by processing conditions.

Thus, this Special Issue will welcome contributions that clarify (by either modeling or correlations) the effects of processing conditions on the quality and, above all, the structure and properties of the moldings. Furthermore, contributions on advanced topics, such as micro-molding, or special techniques, such as gas injection molding, will be welcome. Another relevant topic is the production of high valuable parts obtained combining polymers with other materials, such as for powder injection molding.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
