They are permanently joined together but the process does not involve full encapsulation. Abstract To produce thin-walled plastic items, injection molding process is one of the most widely used application tools. Thermoplastic materials such as HDPE, Polypropylene, ABS and Styrene are used along with a blowing agent which produces a molded article with a cellular core and solid skins. These are the very light duties gears used for transmission of very low amount of power but maintains velocity ratio accurately. Setting up the ideal process for the part, and being able to repeat it, is the key to molding tight tolerance parts. Running colder molds will require an increase in fill time and pressure (actual fill pressure will increase on its own, just make sure you are not running pressure limited). 1 Injection molding Injection molding is the principal manufacturing method used in plastics production.
