Single-ended electric heating tubes: Important points to note when purchasing!
Single-ended electric heating tubes consist of a metal tube encased in a spiral heating wire (located in the center of the tube). The space between the heating wire and the metal sheath is tightly filled with a densely insulating and thermally conductive filler (high-purity magnesium oxide powder). The tube ends are sealed with sealing material, and the ends are connected with conductive lead-out rods for wiring.
Single-ended electric heating tubes are suitable for high and low temperature insertion heating of various molds and mechanical equipment, extrusion cylinders, forming dies, metal castings, rubber machinery, heating and insulation of laboratory equipment, bag making machines, edge banding machines, packaging machines, 3D printers, and sealing machines.
Points to note when purchasing single-ended electric heaters:
1. Voltage and Wattage
The voltage depends on the actual power supply voltage.
The wattage is determined by the surface load and size. Typical surface loads are:
Domestic process: 5W/cm²;
Imported process Grade A: 5W-12W/cm²;
Imported process Grade AA: 12W-15W/cm²;
Imported process Grade AAA: 15W-20W/cm²;
2. Heating Medium: Mold heating (embedded mold heating), open air dry heating, and liquid heating.
Note: When heating molds, pay attention to the clearance between the tube diameter and the mold hole diameter. The clearance is typically less than 0.2mm.
3. Dimensions
The tube diameter, length, lead length, whether or not a retaining plate is included, and the threaded fastener size for liquid-heating single-ended electric heaters should be determined based on the tube diameter.
4. Operating Temperature
Select the material for the single-ended electric heater based on the operating temperature.
5. Purchase Quantity
Single-end electric heating tubes are not quoted by meter; prices are based on the custom quantity.
6. Is shipping tax included?
