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.
Test your knowledge about the injection molding process! Learn about the different stages involved, from loading plastic pellets into the hopper to heating and mixing them until they reach a molten form. Find out how the material is then forced into the mold cavity for solidification.
