The high watt density cartridge must be fitted in a reamed hole to work properly.
The layout of cartridge in the part to be heated must be on a regular pitch. The minimum distance between 2 cartridges is 40mm.
You must use a temperature control device to regulate the temperature of your process. The sensor must be fitted in the middle of the cartridges.
