The material cost of single-head electric heating tube is different

Imported mold single-head heating tube adopts imported materials

The cost of imported mold single-head heating tube is much higher than domestic mold single-head heating tube.

These include: 1.The installation of thermocouples; 2.The selection and installation of far-infrared rope heaters; 3.The performance and selection of insulation materials.

1. Domestic mold single-head heating tube can only be used for external wiring;

2. Imported mold single-head heating tube can be divided into inner lead and outer wiring;

1.Choose a heating method and power supply equipment, and determine the form, size, power and capacity of the ceramic heater. Determine the installation location and the number and location of temperature measurement points. Determine the insulation material, insulation thickness, and insulation width. Determine the rate of heating and cooling, etc.
2.Start the test in accordance with the relevant design conditions, and at the same time record the temperature and time records of the entire process and other processes that occur.
3.alyze the test results.
4.opose the evaluation test report.

9 steps of crawler heater inspection

1) The heat treatment room may be grounded.
2) Whether the computer temperature controller is operating normally, and whether the functions of the keyboard and mouse on the temperature controller are normal.
3) Whether the computer temperature controller and the related grounding protection device of the automatic balance recorder are safe.
4) Whether the voltmeter and ammeter on the crawler heater are normal.
5) Whether the structure of the recorder is complete and the running state is normal, then calibrate and inspect it. After the inspection is qualified, the crawler heater can be used.
6) Whether each output channel of the temperature controller can be used normally.
7) Whether the temperature display on the crawler heater and the record of the automatic balance recorder are the same.
8) Whether the thermocouple number is correct, whether the crawler heater has been calibrated, and the product has passed the inspection.
9) Whether the tools for manufacturing crawler heaters and the protective equipment for related personnel are complete.
