Study Notes
Injection Molding Process
- In the injection cylinder, the plastic pellets are melted to form a molten material.
- The component responsible for mixing the molten pellets in the injection cylinder is the screw.
Loading Process
- The plastic pellets are loaded into the hopper before the injection process begins.
Specifications
- The overall policy statement is a part of the specification that outlines the general guidelines and objectives.
- Poor specifications can lead to errors, defects, and increased costs.
- It is essential to divide the specification into three parts to ensure clarity, organization, and ease of understanding.
- The overall policy statement may include information on the company's goals, mission, and values.
- The environmentally based statement may require information on sustainability, waste reduction, and eco-friendly practices.
