High temperatures, high-pressure hydraulic circuits, and hazardous fumes all pose a risk to operators, and the popularity of injection molding provides many opportunities for accidents. There are methods to prevent safety breaches, but they all involve education on how injection molding works and where the danger lies in the process. Plastic injection molding involves mechanical and thermal hazard sources, where users can experience burns, crushes, impacts, and other dangers. Not only do improper safety procedures jeopardize the longevity of machines, but they can also lead to operator injury, so it is essential to define a working protocol for all aspects of the injection molding process.
