+xWith regards to overloading the oven, this is a difficult question to answer specifically. Basically, any large heavy items will cause the oven's performance in terms of heating and cooling rate to be reduced. For example, we sometimes see a very slow heat up and cool down when multiple very large aluminum tools are loaded into the oven.
The other way the oven can be overloaded is when it is loaded in such a way that the airflow inside is restricted. This restriction means that even temperature control becomes impossible. This is sometimes seen when lots of parts are stacked on a single shelf rather than spread over multiple shelves. It is important when loading the oven that there are gaps between all the parts. Bad loading of this type can cause parts to improperly cure.
This makes a lot of sense. I will make sure there is a good amount of space in between each part.
