Product Details

Mold Single-Head Electric Heating Tube Rod

It is made of metal tube as the shell, electric heating wire as the heating element, and magnesium oxide powder with good insulation and thermal conductivity as the filler, through processes such as tube shrinking, annealing, bending, welding fasteners, etc. This product has one end for wiring, and the surface load design can be: 1-22W/cm2. It has the advantages of small size, light weight, low price, safety and reliability, easy installation, high thermal efficiency, fast heating, and long life.

The internal filler insulates the heating wire from air, keeping it centered without shifting and touching the tube wall, so the tube surface is not electrified. The cold end of this product can be manufactured according to customer requirements.

I. Specifications:

1. Tube diameter: Φ3mm-Φ30mm;

2. Single tube length: 15mm-6000mm;

3. Power: Designed according to the heating medium and size;

4. Tube material: Iron, stainless steel, copper, titanium tube, imported materials;

5. Temperature options: 0-1000°C.

II. Technical Parameters:

1. Operating voltage should be equal to the rated voltage or not exceed 10% of the rated value;

2. For components with rated power ≤100W: ±10%. For components with rated power >100W: +5% to -10% or 10W, whichever is larger;

3. Leakage current: Cold leakage current and leakage current after hydraulic and sealing tests should not exceed 0.5mA; hot leakage current at operating temperature should not exceed 0.12mA;

4. Insulation resistance of heating tube: Cold insulation resistance at factory inspection should not be less than 50MΩ; after sealing test, long-term storage or use, insulation resistance should not be less than 1MΩ;

5. Insulation withstand voltage: Cold electrical strength 1500V/min without flashover or breakdown.

III. Application Range:

Used for mold heating, it has been widely accepted in modern industrial applications. It is widely used in plastic and rubber machinery heating systems, production lines, heat treatment, chemical industry, electric power, ships, aviation, petroleum, cables, chemical fiber, food, medical and other industries. Used for molds, quenching, sawdust ignition, bag making machines, packaging machines, bread makers, printers, tin melting furnaces, flat vulcanizers, extruder barrels, water tanks, oil tank heating, and air dry burning.
