Türk+Hillinger optimizes HPQ series
Now with new and patented clamping for thermocouples
Türk+Hillinger, the market leader for compacted electrical heating elements,
offers a versatile product spectrum for most diverse industrial applications.
An emphasis of the production program are heating elements for the plastics
processing industry.
The product group HPQ which offers a number of advantages to the customers
has successfully established at the market. The heating elements of the HPQ
series are compact and robust construction parts, which are characterised by
their small wall thicknesses. Basis of the nozzle heater type HPQ is a low-mass
high density coil heater, which is spinned into a groove of a cylindrical hollow tube.
The peripherical grooves are usually arranged thread-like with different gradients,
so that an adequate heat distribution can be adjusted along the element to be heated
(generally injection nozzles plastics).
Due to the good thermal characteristics mounting tubes are usually from brass.
The minimum wall thickness is 1.3 mm. In case of restricted installation conditions
and narrow space these small and precise heating elements are also applicable,
as even with larger diameters and lengths up to 400 mm.
Important for the achievement of optimal injection results are an accurately fitting
inner diameter, a precise power distribution of the heating element and an accurate
temperature control. HPQ offer high reproductibility and smallest tolerances.
They have a high dimensional accuracy as well as small power tolerances.
Türk+Hillinger offers now for the HPQ series a new, already patented gap-free
clamping of the thermocouple on the unit to be regulated. Thereby the thermocouple
is fixed such at the point that an optimal contact pressure is permanently ensured
with additional thermal decoupling laterally to the tube wall. This leads to accurate
and quickest response times of the thermocouple and thus to an optimal regulation
and control behavior inclusive best results with high challenging injection tasks.
The thermocouples can be mounted optionally exchangeable or tightly fixed at the
nozzle heaters type HPQ.
Main application area is the hot runner technology where mainly nozzles are heated.
The market demands here a constant miniaturization with increasing precision.
The HPQ series of Türk+Hillinger fulfills also these demands.
