Based on the previous focus on hot runner injection molding scenarios, where improper heating coil installation easily leads to a chain of failures such as overheating and burnout, and heat conduction failure, the time it takes for problems to surface is directly related to the type of installation error:
Serious Wiring Errors: For example, a short circuit in the power cord or reversed temperature sensing wires will trigger an overheating alarm and smoke from the heating coil within 10-30 minutes of power-on, immediately revealing the problem.
Excessive Gap: With the heating coil suspended, heat dissipation is poor. Typically, after 2-4 hours of mass production operation, localized overheating and burnout of the heating coil will occur.
Minor Loose Connections/Small Gap: Only minor loose connections or poor localized fit may gradually manifest as slow heating and uneven localized temperatures over several days to a week.
Strictly following a stepped temperature increase procedure after power-on will allow for the immediate detection of most installation problems, preventing prolonged operation with faulty components.
