IH Catridge Heaters provide a convenient, dependable
and effecient method of applying concentrated heat to solid metal
components such as Die Blocks, Moulds, Platens, Heat Sealing tools
etc,. or practically any application where a compact, insert type
heating is desirable.
|
|
Hot Rod Catridges Feature:
- Long trouble free service
- Sheaths of precision dimensions and tolerances for intimate
contact with reamed holes.
- High watt density units with stainless steel sheaths providing
stable non oxidising surfaces.
- Heating elements positioned close to the outside surface for
maximum heat transfer, minimum core temperature and faster heating
.
- Heating element supported on high quality ceramic and solidly
packed magnesium oxide.
- Variety of connections, including plated stell screws and nuts
or glass insulated nickel wires.

| Insulation : |
|
Holes in metal blocks for catridge insulation
should be drilled and reamed to listed sizes .
Finished units are suffeciently undersized to provide a slip insulation,
when expanded by heat, catridge will fit snugly to give maximum
heat transfer. If air gaps are permitted due to rough drilling or
improper sizing of the bore, hot spots on the sheath surface will
result with consequent deterioration of the heater. Hole must also
be free from oil to avoid heater contamination, again shortening
life.
|
| Mounting and Extracting
Lugs : |
| IH Heaters can be fitted with flanged on
tag mounting lugs to hold heater firmly in place and lead wires should
be supported when in a moving die or platen . Also, lugs ease heater
removal. |
| Control Position : |
| To prevent overheating when using units
rated at maximum watt density as listed, it is recommended that the
control point be located within 12mm ( 1/2" ) of the hot rod
unit. |
| |
| High Density : |
|
| This construction ensures that
the resistance wire temperatures are dissipated much more rapidly
through the sheath than is possible with conventional catridge construction.
Since this fast rate of heat transfer greatly reduces the temperature
difference between the resistance wire and sheath . |
| Sheath Material : |
| Heater maufactured with stainless steel
sheath allowing for continued operation at elevated temperatures |
| Lead Wires : |
| Standard length is 250mm long ( 10"
) of double fibre glass covered stranded copper wire . |
| Ordering : |
|
