Product introduction
micro tubular coil heaters is an advance concept of thermal engineering which has a construction similar to high watt density Coil heaters. These heaters are also known as high performance tubular heaters or cable heaters. The basic construction of these heaters consist of compacted MgO, high temperature resistance wire and Chrome Nickel Steel tube. These heaters can be constructed with or without built in thermocouples type K, E and J. They are usually installed where space available for heating is limited and are widely used on hot runner nozzles, and manifolds, die cast nozzles, packaging machines etc.
Advantages of hot runner heating coil: high working temperature, fast heating, long life service, easy installation and low consumption. Heating coil use: plastic mold, blow molding machine, extruder and hot nozzle, etc.,
the heating line of the hot runner heating ring is fired and can be heated into various shapes. The utility model has the advantages of high working temperature, fast heating, uniform heating and long service life, can automatically control the area, and has high heat conduction effect; at the same time, the internal heating material is damaged, the outside can still be reused, and the heating contact area is fully heated, and the heat conduction is high. , strong resistance to mechanical impact.
Specification
The basic information of the heating coil is as follows:
1. Section (tube diameter)
Flat type: 2.0*4.0 2.2*4.0 2.5*4.0 2.2*4.2
Square type: 3.0*3.0 3.3*3.3 3.6*3.6 4.0*4.0
Round type: double tube 1.8 double tube 2.2 single tube 3.0 single tube 3.6
2. Inner diameter (heating ring inner hole)
Minimum 7MM to 120MM
3. Length
The inner diameter is 10 or less, and the length is 30 or more.
The inner diameter is 10-15 and the length is 22 or more.
With an inner diameter of 20 or more, it can be made according to customer requirements.
4. Cold end (no heat length)
According to customer requirements, the minimum is 13MM to 300MM, and the connection terminal has a fixed length of 30MM.
5. Wire (lead)
There are high temperature Teflon casings and mesh stainless steel casings. Normal 1 meter line length. Can be lengthened according to customer standards;
With temperature sensing (5 lines) Heating line: 2 pieces are gray, regardless of positive or negative.
Temperature line: red is positive and blue is negative.
Ground line: yellow-green.
Without temperature sensing (3 lines) Gray is heated, regardless of positive or negative. Yellow green is the ground.
6. Voltage 220V 230V 240V 380V
7. Power 100W-2000W
8. The quality of the heating ring produced by our company is guaranteed for one year.
Spring hot heating coil: The Spring hot heating coil has various forms such as round and square and rectangular, and the outer surface has two effects of bright and sandblasting. It can be equipped with K type, J type or E type temperature control thermocouple.
It has the characteristics of small volume, high power density, fast heating, precise temperature control, long service life, convenient installation, energy saving and no pollution. Widely used in hot runner plastic molds, blow molding machines, extruders and hot nozzles.
