Telar has a vast selection of injection molding feedscrews for both general purpose and high wear applications. These screws are in stock available for immediate shipment. In addition, Telar can assist you in designing the optimal feedscrew customized to your application. Stock screws include the following machine manufacturers: Van dorn, Demag, Cincinnati Milacron, Toshiba, Nissei, Mitsubishi, Engel, Toyo and many others. We also have a limited supply of extrusion feedscrews and blow molding feedscrews.
We have the industry’s lowest prices and a huge inventory of screws for immediate shipment.
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.
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.
Mixing Screws • Extrusion Screws • Rebuilt Screws
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.
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 Carbide Coating: Guaranteed to double the life of a 9V screw.
Hard Facing – On Screw Flites
Stellite #6: Cobalt based. Recommended for resins with a low percentage of filled materials. 37-42 RC hardness.
Stellite #12: Save as above with 40-47 RC hardness.
Colmonoy 56: Nickel based. More wear resistant than Stellite. Recommended for glass-filled or resins. 50 to 55 RC hardness.
