7. PTA WELD
• Plasma transferred arc (PTA)
hardfacing is a versatile
method of depositing high-
quality metallurgically fused
deposits on medium and high
hardness materials.
• PTA allows precise metering of
metallic powder feedstocks and
produces deposits of a given
alloy that are tougher and more
corrosion resistant then
counterparts laid down by
GTAW or OFW processes.
Weld deposits are
characterized by very low
levels of inclusions, oxides, and
discontinuities.

to handle the most complex
designs in sizes up to 7.5
meters (25 feet) in length by
30 centimeters (12 inches) in

20. Windsor Feedscrews offers a full
range of single barrels for extrusion,
injection molding, blow molding, and
rubber processing. We also offer
barrel repair services which
includes honing, short-sleeving, and
relining

21. Depending on your design
needs, Windsor Feedscrews is
here to help you make the
right decision for your process
Barrel Material Options:
• Bimetallic (Standard or
Carbide)
• Tool Steel (CPM-10V or D-2)
• Nitrided (Gas or Ion)

22. In certain machines the
feed throat is an integral
part of a barrel, therefore
when selecting a plasticator
barrel, manufacturing the
appropriate size and shape
of the feed throat is
essential. The feed housing
section is important in
ensuring that plastics are
properly plasticized

23. To fulfill your injection molding
requirements, Windsor
Feedscrews is a full service
provider and can provide you
with:
• Valves
• Endcaps
• Adapters
• Nozzles
We manufacture front end
components based on your
specifications and are able to
select from a variety of steels or
alloys to meet your abrasion and
corrosion resistance
requirements

24. We produce side feeders
that are either single or
twin screw extruders with
zero compression screws
that positively convey
ingredients into the
stream

25. Depending on many
variables including mixer
length, tube inner
diameter, the number of
elements and their
design, we can
manufacturer removable
mixers to your precise
specifications

26. Choosing the right materials
and design of an auger, can
help to create the right mixing
action to homogenize the
blend of the plasticating
material, this is especially
useful when adding colors or
when regrind is being mixed
with virgin materials

27. Depending on the rotor design,
whether it requires the high intensity
shearing action in the nip as found
with tangential rotors or the cutting
and folding of the sheet as found in
intermeshing rotors. Windsor
Feedscrews will manufacture to your
precise specifications.
We are capable of handling the most
complex designs to ensure that
there is a consistency in the
processing regardless of the
disparities in the bulk densities,
particle sizes or flow characteristics
of the ingredients.
The excessive wear of rotors will
lead to inadequate dispersion. At
Windsor Feedscrews we can rebuild
your existing rotors like new.

28. We guarantee the structural
integrity of our tie bars, which
will provide you with a sturdy
and accurate alignment
mechanism to ensure that the
mold is always properly
located and positioned in
reference to the machine
during the injection molding
process

29. During the molding cycle, the
molten polymer is injected
from the barrel into the mold
through one or multiple piston
channels in the processing
head, depending on the
desired manufacturing
process Windsor Feedscrews
will manufacture to your
precise specifications

31. Windsor Feedscrews is dedicated to serving the needs of each of our customers by
continuously searching for efficiency improvements in the design and manufacturing

35. Upsizing Injection Components
It is possible to increase the capacity of an injection unit without replacing the
entire unit. This modification can usually be done at a much lower cost than
buying a new injection unit. The main factors to look at when deciding whether
an upsizing is feasible are; the capacities of the existing hydraulic system, the
design of the barrel, and the resins to be processed. When an injection unit is
upsized, the barrel is modified, and a new screw, valve and endcap are installed.
Downsizing Injection
Components
Sometimes, you may wish to
downsize an injection unit. When an
injection unit is downsized, a new
barrel, screw, valve and endcap are
needed. Under some
circumstances, it may be possible to
use the existing barrel. We take
special care to ensure that the new
barrel has adequate strength to
offset the higher injection pressures
that may result from downsizing.

36. We offer various heat treating and plating options which include:
• Flame Hardening and Thru-Hardening
• Precipitation Hardening for Stainless Steel
