A Twist To Resist - a component journey
The extruder screw begins life as a forged steel bar.
An empty cylindrical steel capsule is manufactured. The steel bar is placed into the centre and the free volume is filled with metal powder.
The bar requires cladding to add a layer of wear-resistant material. This material will be produced from high quality steel powder.
The capsule is HIPed to fully densify the powder metal and bond the steel bar creating a coating.
The outer profile is machined to the final shape and dimensional tolerances.
The finished screw is hardened and tempered using a thermal cycle engineered to allow the material to retain toughness whilst allowing optimum hardness characteristics in the (clad) surface.
K-Tech coating applied for increased wear resistance, corrosion protection, and anti-galling.
End Application
Plastic extrusion equipment.
