Injection Molding Screws – Extrusion Feed Screws
Telar has been supplying plasticizing screws for use in the injection molding and extrusion industry for the past 25 years. If you need a replacement screw quickly we have a large inventory of OEM replacement feed screws for many machine makes in both high wear CPM 9V and GP nitrided at a huge cost savings. We can also expedite screws in 5-7 days if lead time is critical.
If you are looking to improve your process, our Telar BarMix high performance feed screw has helped processors increase production 30% over their current barrier screw design. Our knowledgeable staff will design a screw tailored to your precise application. We also can thermal spray coat screws for both highly filled and/or highly corrosive resins. In addition, we engineer upsize/downsize for your injection unit and can do thermoset retrofits. Telar also repairs broken screws quickly to get you back up and running and we also rebuild worn screws back to OEM specifications. We understand lead time is critical and we will do our best to provide superior service to meet your expectations.

Custom Screws
BARRIER – MIXING – CUSTOM
Telar can design a screw specifically for your process to deliver peak performance. If you would like to decease cycle times, improve mixing, or reduce scrap rate, we can assist. Sometimes a small change in design and/or material composition can result in significant overall screw performance.

Carbide Coating – Double the Life of Your Screw
The ultimate for high wear/ highly corrosive/high temperature applications – guaranteed results
Full Encapsulation provides the ultimate in abrasion and corrosion resistance for single and twin feedscrews. This option covers the tops of flights, flight sides and the root/core of the entire feedscrew.
Carbide coating is recommended when process very high fiberglass content, calcium carbonate, titanium dioxide, metals, ceramic or other abrasive fillers.
High wear/High Abrasive resistant feed screws
Telar provides screws manufactured in high wear tool steel for your most demanding applications. Telar high wear tool steel screws are manufactured in CPM 9V a Crucible material with 9% vanadium carbide. We can also offer screws with an XC-1000 coating for extreme wear and corrosion resistance. We start with a 4140 screw substrate and then use a thermal spray weld up to .010/side of tungsten carbide coating for superior screw wear resistance.
High Performance Screws
Telar can design a screw specifically for your process to deliver peak performance. If you would like to decease cycle times, improve mixing, or reduce scrap rate then let the engineers at Telar help determine the optimal screw design. Sometimes a small change in design and/or material composition can result in significant overall screw performance.
General Purpose Screws
Telar has hundreds of screws on the shelf for immediate delivery. Our GP screws can be either nitrided or welded with Colmonoy 56 hardfacing and either chrome plated or nitrided. These screws typically have a 3:1 compression ratio and are excellent for typical molding applications. We can ship same day and with low prices these represent an outstanding value. Please check out our current list of in stock screws available for immediate shipment.
Feedscrew Repair
We can repairing your worn injection, extrusion or blow molding screw back to OEM specifications. After inspection we will provide you with an analysis and price quotation to repair. The repair process includes stripping the current screw, grinding and elding stainless onto the flites, applying Colmonoy 56 hardfacing for protection and then applying chrome plating if required. A rebuilt screw can be a great value as it typically can cost 50 – 75% of the price of a new screw.

Feed Screw Materials
Nitralloy 135M: A tool steel machined and nitrided for 72 hours. An excellent low-cost alternative when excessive wear is not a primary consideration.
4140: A tool steel with good strength when surface threted or hard faced.
D-2: A high carbon/high chrome tool steel. Good wear resistance but low on torque strength
CPM-9V: Excellent for abrasive applications with very good wear characteristic.
Surface Treatments for Screws
Nitriding: Increases the hardness and life of tool steel screws such as 135M and 4140. Very cost effective.
Chrome Plating: Offers hardness and low friction with corrosion protection. Double and triple chrome plating often used for corrosive applications.
Carbide Coating: Guaranteed to double the life of a 9V screw.
Hard Facing – On Screw Flites
Stellite #12: Cobalt based. Recommended for resins with a low percentage of filled materials. 40-47 RC hardness.
Colmonoy #56: Nickel based. More wear resistant than Stellite. Recommended for glass-filled or resins. 50 to 55 RC hardness
Colmonoy #83: Nickel-tungsten based. Contains tungsten carbide particles for extreme wear applications. 59-64 RC.
