resulted in instances of overestimating the cure time and overcuring
High UV intensity from the number of cycles of radiation would increase the risk of overcuring
, and consequently of degradation to the cured films.
With multiple parts often being produced in the same moulding cycle, there is the potential risk of undercuring or overcuring
For the compounds that had received anaerobic overcuring
or aging, the change in weight could not be ascertained as specimens remained in the mold during aging, and flash became a complicating factor.
Percentage of good and scrap parts made by each machine can be represented by a bar chart, while causes of rejects (e.g., overcuring
, warping, or bad trimming) can be shown on a pie chart for each shift or other period.
The minimum overcuring produced by Weave limits curt distortion because the polymer structure has some give in it that allows it to accommodate internal stresses.
Quadrax engineers are six months away from adding software algorithms that provide laser-depth off-setting, a feature that would avoid overcuring on overhang features caused by the laser's constant cure depth.
These include the use of N- nitrosamine-blocking agents such as ascorbates and [alpha]-tocopherol, or a lowering of the addition level of nitrite in order to prevent overcuring
with its undesirable consequences.
leads to such problems as low "elongation at break" while undercuring yields a low tear resistance.
