Heating Elements for Hot Runner Mold Systems: Tubular Heaters

When choosing replacement parts for your furnace, cost ought to not be as critical as most companies make it. The cost of heating elements between a good manufacturer and a bad one is negotiable, as compared with the overall financial investment. The production time and quality of the parts acquired by choosing a respectable manufacturer will more than make up the difference. Keeping in mind the following tips when choosing a manufacturer will ensure less downtime due to a defective item.

Manifold Heater and Cartridge Heater.

Cartridge heaters are utilized around the flow channel to ensure uniform temperature levels. It is important 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 ensure an accurate reading.

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

A few of the most common causes of failure consist of:

Lead short out.

This can be corrected by changing the lead type. If fiberglass leads were utilized, this might be the cause. Hot runners by nature produce gases, which over time, saturate the fiberglass material, causing it to short out between the leads. Depending upon 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 correctly.

This can be caused by 2 different reasons. One reason is the thermocouple needs to be found in the center of the heating element. If not, you will never acquire a correct 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.Go To The Web Site\nPhoenix AZ Heating Repairs
