What is the first step in calibrating a chopper gun?

The first step in calibrating a chopper gun involves setting the catalyzation level. This is crucial because the performance and curing of the resin depend significantly on the correct proportion of catalyst to the resin. Improper catalyzation can lead to a variety of issues, including inadequate curing, which adversely affects the integrity and performance of the final composite material.

Once the catalyzation level is properly established, other adjustments, such as the chop chute position, the chop/resin ratio, and the spray pattern, can be made to fine-tune the gun's operation and ensure the desired outcomes for the composite being produced. However, focusing on the catalyzation first ensures that the material itself will behave as expected during the application process.
