PVS-Kunststofftechnik, a company specializing in overmolded insulation and
other precision parts such as cooling fans for the electronic industry, has
used Stanyl® PA46 for the stator of the latest electric waterpump produced by
Pierburg, the world’s first series-production supplier of electric coolant
pumps.
Overmolding is a relatively new technology and is offering value trough the
possibility of adding 3D geometry and replacing powder coating or paper
insulation. Using overmolding technology offers environmental benefits whilst
saving processing time and reducing the number of steps in production.
Overmolded insulation is a new application area for Stanyl PA46, which is
available in standard, HF (HighFlow) & SF (SuperFlow) grades. Prior to this
application, Stanyl PA46 had not been used for these types of overmolding
applications. According to
Bernd Szedlak, Project leader PVS: “For this application, Stanyl TE250F6 was
selected because it offers excellent flow and its key advantages include
elevated temperature resistance, improved heat dissipation, constant quality
in dimensions and design freedom that allows for integrated functionality. The
material makes it possible to create wall thicknesses in insulation areas of
0.35mm.”
Stanyl TE250F6 PA46 is a 30% glass-reinforced, heat-stabilized and
flame-retardant formulation. It is typically specified for applications that
benefit from its 180+C temperature resistance, good dimensional stability, low
creep, high modulus, good in-mold flow, and ability to meet regulatory
requirements.
PVS-Kunststofftechnik in Niedernhall, Germany, is a leading manufacturer of
high-quality plastic parts and assemblies. The company is specialized in
Ventilation Technology and Electric Motor Components for Automotive, as well
as Electrics and General Industries. Managing Director Jürgen Frank says:
“Stanyl provides unmatched performance and combines the best mechanical
properties at high temperatures, excellent resistance to wear and low
friction, outstanding flow for easy processing and exceptional design freedom.
The use of Stanyl PA46 offers new opportunities for us to expand our range to
include overmolded insulation and other precision parts like cooling fans for
the electronic industry.”
