Heating Elements for Hot Runner Mold Systems: Tubular Heaters

When selecting replacement parts for your heater, cost ought to not be as crucial as many companies make it. The cost of heating elements between a good manufacturer and a bad one is negotiable, as compared to the overall investment. The production time and quality of the parts acquired by selecting a respectable manufacturer will more than make up for the difference. Remembering the following ideas when selecting a manufacturer will guarantee less downtime due to a faulty product.

Manifold Heater and Cartridge Heater.

Cartridge heaters are utilized around the flow channel to guarantee uniform temperature levels. It is necessary to keep the distance between the heaters and the manifold equal or greater than 1x the diameter of the heating element.

Thermocouple placement ought to be located equally distanced between the heating element and the flow channel, and ought to be set deep to guarantee a precise reading.

If an internal thermocouple is utilized, it is necessary to make sure that it is located towards the center of the heating element, depending on whether the controller is grounded or ungrounded.

Some of the most typical reasons for failure include:

Lead short out.

This can be remedied by changing the lead type. If fiberglass leads were utilized, this might be the cause. Hot runners by nature create gases, which in time, saturate the fiberglass material, causing it to short out between the leads. Depending on the ambient temperature around the lead area, Teflon leads can be utilized to correct this, as they are more resistant to gases.

Internal thermocouple not reading properly.

This can be caused by two different reasons. One reason is the thermocouple must be located in the center of the heating element. If not, you will never acquire a proper temperature of the flow channel. The other reason is whether or not the unit is grounded or ungrounded. Consult your controller manufacturer to determine this.Fort Collins Colorado Heating Repairs\nFor more Info go to
