Dear Everyone,

Good day!

First I would like to thank everyone especially this site to where I learned the way of scientific molding.
Now, for my concern, we have molds in our customer that reportedly experiencing frequent busted nozzle. At least two to three times of having this problem for a month of production.
When we asked them, they mentioned that it is due to type of heater used that is prone to problem. The existing nozzle heater is an INCOE cartridge heater. Now we are planning to reply the whole runner system to make the nozzle heater with cable heater (tubular type). The modification is costly and we need justification that the problem is really because of the type of heater.
Honestly, I am not familiar with the hot runner system cause for in seven years in the industry, I only handled cold-runner type.

Your insight on this concern is highly appreciated.

Thank you very much every one!
