Understanding Plastic Processing Machinery and Its Core Components
To appreciate the importance of screw barrels, we must first look at plastic processing machinery (PPM) as a whole.
PPM comprises the following equipment:
- Injection Moulding Machines
- Extrusion Machines
- Blow Moulding Machines
- Compounding & Mixing Equipment
All of these processes require that the equipment operate under high temperature and pressure conditions to melt, mix and shape plastic into usable parts. The degree of efficiency of transforming plastics into usable products depends on:
- Temperature Control
- Consistency of Material Flow
- Homogeneity of Mixes
- Wear Rates of Components
The screw barrel assembly of PPM is responsible for transporting, melting, compressing, and homogenizing plastic materials. Thus, any inefficiency in the screw barrel assembly will adversely affect product quality, cycle times and energy consumption.
Therefore, manufacturers around the world are looking to experienced manufacturers that are also high-precision engineers.
Why Screw Barrel Quality Defines Machine Performance
