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 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 knowledgeable staff can design a screw tailored to your precise application. We also can also thermal spray coat screws for both highly filled and also corrosive resins. In addition, we can engineer a screw and barrel upsize/downsize for your machine and we also repair broken screws and 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.
The most common screws in stock from the top machine manufacturers – Van Dorn/Demag, Cincinnati Milacron, Nissei, Toshiba, Toyo, Engel and more. Range in size from 18mm to 155mm in both GP and high wear CPM 9V. Same day shipping available on orders received by 5:00 pm EST. Rush orders 1-2 weeks.
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.
Our ultimate high performance barrier mixing screw has a sub-channel design to continuously churn and mix the particles with uniform melt temperature. By reducing shear heat we can increase efficiency and melting. Lower melting temperatures will increase output. Processors have increased production up to 30% with the barrier mixer design. Let our experts design a custom screw that will outperform your current screw and maximize your machine output.
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.
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.
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.
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: Guaranteed to double the life of a 9V screw.
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.
