Hot Runner Systems for Medical Engineering0 pages

Principle of Thermal Separation
• Two-part shaft for good thermal
separation between nozzle and
mold insert
• Low heat flow into the cavity
• Constant temperature control
in the nozzle
• High leak
tightness
between nozzle
and mold insert

Cover: Production line for producing
and bottling infusion solutions. A special
closure is placed on the filled bottle and
subsequently overmolded with PE.
This application uses a modular valve
gate hot runner system from GÜNTHER.

Valve Gate Technology
Valve gate technology offers clear benefits including:
• superior surface finish in the gate area
• high process reliability
• low shear rate of the melt to reduce orientation and
residual stress of the part
Valve gate technology takes advantage of a modular
nozzle design. Narrow pitches are possible. One can
choose between different types of needle actuation:
single valve gate nozzle or, in multiple systems, single
needle valve, lifting plate or sliding plate mechanism.
The needle can be adjusted from the outside without
mold disassembly. A wear-resistant needle guide
made of PM steel guarantees long service life. Various
gate diameters are possible without refinishing the
inserts.
