Selecting the Best Metering Screw for Your Resin
To choose the correct screw design for a resin (or resins), we need to understand metering screw design factors and their effects on material processing.
Five main variables determine how a screw turns solid resin into a melt. Adjusting them, in tandem with various mixing screws and barrier options, yields a range of results. The variables are:
- Profile
- Channel Depth
- Compression Ratio
- Length/Diameter (L/D)
- Helix Angle
