Tips to avoid stick deformation
When making sticks, we usually face deformations in the middle of the product like small depressions and holes.I’m using this eco packaging on my deodorant stick and the main problem is that a hole is formed in the same way as shown below. It continues until the bottom of the package.
(Supplier images)I know I can heat up a scoop or something and run it over the top of the stick, but the hole would still be below and with use it would be revealed. I want to avoid this situation.The first thing that came to my mind was putting a sample under refrigeration. Do you think it would work or is the problem something else?
Thank you in advance!

You’re filliing too hot. The heat is concentrated in the center and as the sides cool faster it creates the hole in the center. Try filling at a lower temperature closer to the temp where your mixture still flows, but is starting to congeal. Then put it in the fridge to facilitate rapid cooling. You may still get a slight indentation that you can fill in as needed.

@MarkBroussard - Thanks! Sometimes we’re so immersed in the processes that we don’t think beyond what we see
I will do as you said, thank you very much!
