Reiloy screws

Armoured flights, through-hardened, and with treated surface.

Highly wear-resistant screws will not just extend the service life of your plant. They will also improve the quality of your products. We can offer you all kinds of screws for extrusion and injection molding: 3-zone screws, multiple thread screws, barrier screws, vented screws, or highly complex twin screws.


Reiloy Screws
Always of the highest quality.

Screws with armoured flights

The flight is the area of the screw that is exposed to the highest loads. Armouring this area with alloys improves its wear and corrosion resistance. The armouring alloy is applied by using plasma powder welding. The armouring layer has a thickness of 1.5 to 2 mm. The entire screw surface is ion nitrided in order to protect the screw root and the flights. The surfaces of the screw root and the flights can also be hardchrome plated.
