Racer CNC Milling

The Racer utilizes patented Phantom Technology™ which greatly reduces cutting time while still maintaining precision

and performance

Machining up to 6 inches in diameter by 288 inches in

length


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.

Production Capabilities

PRODUCTSWe specialize in the

manufacturing, repair, and rebuilding of screws and barrels for a variety of industries including

plastics, rubber, food and many more. We offer a

complete range of screws, barrels, and

front-end components. Our capabilities are large

enough to handle the most complex designs in

sizes up to 7.5 meters (25 feet) in length by 30 centimeters (12 inches)

in diameter.

70mm Polygon shank with gauge

250mm Troester spline

At Windsor Feedscrews we

can manufacture all

designs no matter how

complex

BARRELSWindsor 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

BARRELS

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)

FEED HOUSING

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

FRONT END COMPONENTSTo 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

SIDE FEEDERS

We produce side feeders that are either

single or twin screw extruders with zero compression screws

that positively convey ingredients into the

stream

REMOVABLE MIXERS

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

AUGERS

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

ROTORSDepending 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.

TIE BARS

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

PISTONS

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

UPSIZING / DOWNSIZINGUpsizing 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 ComponentsSometimes, 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.

HEAT TREATING & PLATINGWe offer various heat treating and plating options which include:

• Flame Hardening and Thru-Hardening• Precipitation Hardening for Stainless Steel
