Technical troubleshooting – machine and tool compatibility

Context

Tool transferred to a new machine. The PP component showed unstable filling.

Initial Problem

Incomplete filling and an unstable mass cushion.

Technical Analysis

The utilization of the screw was 17%, below the recommended range.

Cause

Disproportionate cylinder volume compared to the injection volume.

Solution

Selection of a more adequate machine configuration.

Result

Stable plasticization and consistent filling.

Engineering Conclusion

The size of the machine alone does not guarantee process stability.
