We make Injection Moulding Screw Barrel for some of the largest companies in India. To see our customer list see pictures at the end of this page. Injection Moulding screw barrels are easiest type of screw barrels as they are simple and have less flights compared to body ratio.

One important thing to be noted while procuring injection molding screw barrel is you must have drawing of your screw, otherwise a manufacturer will charge much more than the original cost of that shaft. So whenever you buy screw, ask your supplier to provide drawing and check your screw according to drawing, which is not a rocket science.

If you have a drawing you need not to disclose your machine/model number, what polymer you process in what composition.

You can keep your processing details confidential, and send drawing in mail to all manufacturer, ask them to submit quote according to your drawing.

Injection molding feed screws can be economical if you have drawing.

Another important thing is to know the details of your required bimetallic coating or Carbide coating, because coatings range from 0.0 % (W) Tungsten to 90% (W) Tungsten, so the price you are paying is for material used in coating and the method used to apply coating.
