Nozzle Heaters
The
heating of nozzle in injection machines is still today a big problem
owing to the costs incidence and subsequent stops of the production
process.
Hitco analyzed
a large series of cases causing an early failure, most of them due to
plastic leakage impregnating the heater and causing a range of effects
as:
·
Carbonization of material near electrical
connection which causes short circuit.
·
Penetration of material into the heater will
lead carbonizing it. It causes the loss of insulation due to
perforation of the element.
·
Damage to the structure of
the element using tools for making the attempt of removing heater
covered by plastic element.
·
Tearing of the feeding cables, which can arise both
making the above action and careless during installation of the molds.
We take care particularly of
- Mechanical Sturdiness
- High resistance of the cable to tears and
accidental impacts.
- Sealed construction against plastic material
penetration
- Protection of the connection point between
resistance circuit and feeding
Besides, high specific power reachable with Tubular
Band Nozzle Heater for High Temperatures, up to 15 w/sq.cm on the
nozzle and its excellent mechanical characteristics giving a consequent
unlimited wrapping possibilities of the tubular element, it allow to
solve most complicated heating problems when existing the need of a big
heat contribution in short time and at controlled temperature.
Whole ranges of nozzle heater are manufactured in
accordance with safety rules and they are submitted to a final safety
and quality tests according to the European standards.
On request we can supply relevant
certification for each heater.
