Tight or Loose Grooves in Soap Molds

Question:

I noticed that some of the grooves in the molds are tight, others a little loose.

Answer:

The HDPE plastic is poured and therefore, it is not perfect. However, it is the perfect plastic and composition for this type of use. I can vary in its 3/4″ thickness as much a 1/32″ either way. This will not affect the molds performance.
