China Gold Supplier for STEEL PLATE to moldova Importers

From 30 x 25 mm to 2.000 x 600 mm
(in case of a smaller width correspondingly thicker)

This is my take on forging a light weight, English “Colonial period” hewing axe using bowtie construction. Mild steel body, cutting edge is 1075.

Good insulation properties, current technology enables the
reduction of the thermal conduction U-factors (heat loss rate) of a
normal aluminium frame from over 4,5 down to 3W/m2 K.

Application in a wide range of temperatures (from – 30° C to
+ 210° C). Nowadays a good aluminium window system must
be anodised or treated with powder paint, this means that the
assembled frame has to pass such operation which takes 15/20
min at 200°C, without undergoing any distortion.

Very good mechanical properties, the joint is responsible for the
mechanical connection of the interior and exterior window frame,
the final execution of the frame is proportional to this performance.

Thermal expansion coefficient similar to aluminium material to
avoid internal stress that compromises the mechanical resistance
of the frame.

Last but not least a good process capability to attain an extruded
profile with tight tolerances.
This long list of characteristics reduces the choice to few
thermoplastic materials, among which the best solution is a
techno-polymer based on PA 6.6 reinforced with 25% fibreglass.
Single screw extruder is the best solution to process PA + 25%
fibreglass.

28:1 L/D ratio is suggested for a good melting of the material; an
accurate temperature control of the profile is a must to keep a
good tolerance on the final profile.
A special attention is given to problems due to wearing. Adding
25% fibreglass to the material, special steel and treatment must be
used to reduce the wearing on barrel and screw surface.

A particular screw design allows good performance and the
possibility to use up to 20% regrind material without reducing the
line performance and the final quality of the profile.
