Features of Screw Tip Set
Enhanced Melt Quality
Screw tip assemblies, particularly those with a check ring, help create a more uniform and homogeneous plastic melt. This is achieved by preventing backflow and ensuring proper mixing of the material during the injection process. Improved melt quality leads to better part surface finish, reduced defects, and increased dimensional accuracy.
Improved Control and Repeatability
The check ring mechanism in the screw tip assembly provides a consistent melt cushion, which is essential for accurate and repeatable injection shots. This results in reduced variability in part weight, dimensions, and other critical characteristics, leading to more consistent production.
Reduced Material Waste
By preventing backflow and ensuring proper melt consistency, screw tip assemblies minimize material waste due to inconsistent molding. This leads to lower production costs and reduced environmental impact.


- Make sure the screw tip assembly threads and feedscrew are clean.
- Apply anti-seize compound on all threaded areas during assembly.
- The anti-seize will enable easy removal of the tip assembly in the future.
- Assemble the tip assembly to match the diagram below exactly.
- Make sure the register of the screw matches perfectly with the seat.
- Screw the tip assembly into the feedscrew and tighten.
