Processing Of Injection Screw Designing

Injection screw designing is quite popular among not only engineering companies but among those who are looking for quality injection molding design as well. The top notch manufacturing firms can build screws for various applications such as single & multi flighted, barriers, variable lead etc. Only a reputable and recognized company can have the capability to process polymers with greatest output so that clients can stand out from others. It is crucial to utilize right injection molding screws in order to craft quality parts on constant basis with utmost output. Injection screw designing is the process in which few elements such as weight, thickness, size and materials are considered seriously. It is extremely essential to check out the details of screw to get a fair idea about the handling and performance requirements. Injection screw designing has basically three major zones which may include: •

Feed zone

Transition zone

Metering zone

There are different kinds of screws utilized and manufactured by engineering firms. It may include: •

General purpose screws

Barrier screws

Double flight screws

Wear resistant screws

General purpose screws can be utilized with almost all kinds of plastic materials like PP, Nylon, PC, PET and PE. These materials are quite good for molding process and can be mixed with different other materials. However, it is always recommended not to mix the general purpose injection screw designing with other materials as it may harm both. Barrier screws offer good quality and usually melt at much faster rate comparatively GPS. There are numerous barrier screw designs but may vary when it comes to channel widths and flight depths.


There are different designs for double flight screws and it is a great alternative for barrier screws. These are designed to produce quality melt at much faster rates comparatively. This kind of injection screw design ensures that plastic is fully melted and can be utilized in various technical parts of PP along with PA. When it comes to wear resistant screws, these are produced using heat and have longer shelf life as compared to non heated parts. The material is very abrasive but has good life. Bimetallic screw barrel designing is another to attain quality screws at much affordable prices. This technique is widely used by many engineering companies and gives good results. It is important to choose a reputable engineering or manufacturing company in order to attain best results. So, find shortlist few good injection screw designing companies and explain your requirements in detail!
