Sealed hot runner band heater coil heater with cover for plastic
injection moulds
Description:
1) Hot runner heater is an advanced concept of thermal engineering
which has a construction similar to high watt density cartridge
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. 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.
2) A Coil Spring Heater in its unformed straight stage can have a
maximum length of 6ft and its cross-section can be square or
rectangular, while a cable heater can be 300ft long and is
available in round cross sections. Thermocouple sensors could be
installed internally at the tip or the middle of a heater.
Specification:
1) Thermocouple type : We manufacture it according to the Chinese
Industrial Standard(CIS),and we can manufacture as your
requirement..
2) A class unit price made with import material, with stable
Temperature, and a long working life. B class unit price made with
general material.
3) The normal cable length is 1000mm,also we can make the length as
you need.
4) The leading wire type use fiberglass silicone copper wire ,PTFE
wrapped copper wire ,and the others should be customized.
5) material :SS 304,Mgo,Heating coil
6) The normal voltage is 230V,we can make the voltage as you need.
7) Sleeve types A class watch with A1,A2,A3,B class watch with
B1,B2,B3,The normal is B3.
8) surface highest temperature:750℃
9) Diameter of the tube:±0.1%
10) Error of power(not heated):±+5%~-10%
11) Intensity of high votage:700V
12) Insulation resistance(not heater)≥0.5MΩ
13) Laekage current(not heater 253V):≤0.5MA
14) Error of heating length ±5%,Error of cold zone +0mm~-10mm,Error
of connection length ±2mm.
