38CrMoAl nitriding pultrusion moulds
Material
performance:
After nitriding, this material has high inner strength and
surface hardness. It has supreme abrasion resistance and antifatigue. It's fit
for producing pultrusion moulds with high abrasion resistance , high antifatigue
and fine finish. This mould is a recommended mould for making window materials
and special profiles. It can make moulds with hardness over HRC-62 and can
successfully make over 200 thousand metres' products. It's
harder,demanding,time&money wasting to make the pultrusion moulds with this
kind of materials. This material is fit for making high quality,small-mouth and
complex section pultrusion moulds. It's also the first choice of famous profile
manufacturers home and abroad.
Cr12MoV quenching pultrusion
Material
Performance:
Cr12MoV moulding steel is a representive of high-carbon and high
chromium moulding steel. So it has high permeability,high quenching,high
abrasion resistance and deforms less. Because of its high quality and overall
hardness, its fit for making regular FRP profile moulds with huge sections. Now
companines home and abroad widely adopt nodular cast steel for the outer part of
the mould and Cr12MoV steel for the inner core of the mould. It's
heavy,time&money wasting, but it's hard to change shapes and has super
stability. It's popular with all customers.
40Cr intriding pultrusion moulds
Material performance:
After high
temprerature treatment,forging,tempering and destressing, it has fine mechanical
performance, fine low temperature impact toughness.
Advantage:
High
overall hardness, high finish, low pultrusion resistance. It's fit for
pultrusion of unsaturated resin and mass production within 40000 metres. After
nitriding its hardness can reach HRC-55.
40Cr/S45C quenching pultrusion moulds
40Cr pultrusion
moulds use the same raw material as Nitriding moulds,except for the different
surface processing. Hard Chromium plating pultrusion moulds are widely used, and
they almost can meet the demands of any pultrusion resin. However, due to the
instability of electroplating, they have a shorter life. So they are fit for
small batch production and special pultrusion moulds.
S45C moulding steel, as
a heating moulding steel, is a common mould material. After its tempering and
aging processing, it has bigger stability. This mould costs lower and can be
finished within a shorter time, so it's widely used by the manufacturers . They
are manily used in FRP cable bridge and other lower precision-demaning and minor
production products.

Processing
technology:
1. After heat treatment, the cavity is plated with hard
chromium.
2. Overall nitriding cavity mirror
polishing.
