Custom-made hot runner systems fully mounted and wired

The new H4015/… fully wired hot runner systems complement
the extensive HASCO range of mounted standard systems,
installation systems and hot sides with a further interesting
component.

The main advantage of this new offer is the electrical wiring
of the complete hot runner system carried out by qualified
personnel. The connecting cables of the individual nozzles
and the hot runner are routed to the terminal box via
individually fabricated cable ducts where they are then
wired according to the specifications of the customer.
This avoids additional connection expense for the mould
maker or injection moulder and guarantees a smooth start to
production. The electrical safety and correct allocation of the
zones to the manifold heaters and nozzles is ensured by
HASCO and is documented in an individually compiled test report.

A further significant advantage is the fixed interlocking connection
between nozzles and hot-runner manifold, which makes assembly
and disassembly of the system considerably easier.

All nozzle lengths are exactly matched. In line with the established
HASCO installation principle, the nozzles are not screwed to the
manifold block, but are mounted floating on the hot runner.
The inevitable deformation of the nozzles through radial heat
expansion of the manifold, so critical with short nozzle lengths
and large pitch centres, is avoided with this unique construction.

The nozzles can be positioned with “cold dimensions”, which
makes installation considerably easier. The heat expansion of
the manifold beam occurring during heating is safely
compensated by the floating bearing. Therefore, no bending
torques or shear stresses occur in nozzle body. This increases
the life cycle of the nozzles and the tool life of the sealing area.
A secure seal for the system is guaranteed in the tool via the
calculated thermal expansion of the nozzle head and manifold.

Assembly and disassembly of the system is made significantly
easier through the structural design described above. This
prevents damage to the hot runner during mould maintenance,
and is also ensured by the mounting points on the manifold,
which enable easy removal from the cavity plate. Distortion to
the system due to tilting during removal are safely avoided.

The systems are individually designed, constructed and produced
by HASCO in close coordination with the customer. HASCO can
therefore guarantee dimensional accuracy and correct electrical
wiring. We also guarantee it’s leakproof between the nozzles and
manifold.

When used in conjunction with the new Hasco nozzles Z33ff, it
enables an easy and safely mountable hot runner system for the
customer. The new Z33../... with screw-on caps further increases
the mounting safety for such systems and minimises production
hazards for the customer. It also eliminates the processing expense
for introducing the gate geometry and the front nozzle sealing area
into the mould insert or mould plate, which represents a major
simplification for long nozzles with small diameters. The sturdy
and easy-to-produce fit diameter (tolerance H7) can easily be
produced by conventional processing methods (jig boring).

The wired hot-runner systems H4015/… represent an optimum
compromise between mounted systems and hot halves, in that
they offer the advantages of the complete hot half H4400/... at an
attractive price/performance ratio and extremely short delivery times.
