We’re the leader in component technology in the plastics industry. To become a leader, we strive to get our
customers what they want, when they want it, before they know they need it. That’s why our
list of services is as diversified as it is!
The selection of the proper screw for a given plastics processing application (be it an injection molding screw, extrusion or blow molding screw) is critical to its success. Den Scoth Engineering Pvt. Ltd. has documented cases where customers have improved production rates (cycle times) by more than 25% by simply changing to an improved screw design. In other cases, part reject rates have been reduced from more than 5% to less than 1/2 of 1% by utilizing a custom designed mixing screw. These facts alone illustrate the importance of the screw and its design to efficient processing performance.
The Eagle can be designed to process most resins manufactured for your application and is a proven winner in extrusion, blow molding and injection molding environments. If a number of different resins are being processed with the same screw, that screw should be designed to optimize its performance, allowing for all the materials to be processed with reasonable success.
Den Scoth Engineering Pvt. Ltd. engineers work hard to gather the information needed to design the screw most suited for your particular processing situation. All the variables of screw design are discussed on the custom designed screw page under services and in the screw design processing tips section. When we manufacturer a new injection molding screw, extrusion or blow-molding screw for you, our design engineering capabilities are provided to you at no additional cost.
Fligiht repairs are performed using a multi-step welding process utilizing plasma transferred arc welding with a complete quality control system.
Root and Radius repairs, as required, are made with compatible base metals or hardsurfacings for value added protections against future damage.
Full leangth coatings offer additional protectioin to extruders processing fiberglass or talc reinforced resins.
Before applying the hard facing the screw is first under ground to remouve the heat effected material.
When the protective layer has been applied the flights are pre-ground and the edges milled.

With our range of up-to-date, multi-purpose machines we can meet any conceivable requirements in house.
The finish grinding completes the reconditioning process. Screws are nitrided, chrome plated or finished as requested.
The screw leaves our production line after the final quality control. Our dispatch department pack it carefully and send it back to you.
As barrels wear the clearance between the screw flight and barrel wall increases, especially in the high pressure areas of the barrel. Buying a new screw for an worn barrel does not solve the clearance problem. It may make it better, but it is not a fix for a worn barrel.
Since barrels only wear in the high pressure areas or where fusion of the polymer takes place, measuring the end of the barrel ID does not tell the whole story of wear.
A bore gage should be used to measure wear all along the barrel. Keep in mind that the screw wear has to be taken in to account with Barrel wear to determine the total clearance. If you don't know what your wear dimensions are, we have the tools and can measure your barrels.
