Cleaning a screw and barrel can be a full day's job, even when conducted by two or more operators. It can be done by removing parts or injecting a purging compound. It is not always necessary to remove the screw and barrel from the machine, however it may be more cost effective than using a purging compound. The following will guide you in either method of cleaning.
If you're an injection molder, you probably know how sticky urethane can be and how difficult it is to remove from the steel cavities and cores of molds in the injection molding machine you're working with. Using a release agent on the steel surfaces will loosen the urethane in order to remove it. A surface treatment that works well for this is Nano Mould Release Coating. This is actually a line of products that advocates using nanotechnology in their "mesh-like" microstructure of the solution to absorb and removed any remnants of surface debris, including urethane.
Injection molding is the most common way to manufacture plastic products in high volume. Injection molding machines operate horizontally or vertically to fasten and employ molds. Most machines today are horizontally-oriented, however vertical machines are primarily used for insert molding in order for the process to utilize gravity.
