Short answer: Rubber and plastics machinery use nitrided and bimetallic steel extruder barrels and tool-steel screws for wear and mixing under heat, cast iron and steel platens for rigid stable clamping, tool-steel and stainless moulds for precise corrosion-resistant cavities, and stainless or copper heater bands for conductive heating, all chosen for wear, corrosion and thermal duty in polymer processing.
At a Glance
What the Machinery Needs
Wear, heat and corrosion lead the choice, with the basis in our Metal Strength Comparison and hardening in our Nitriding vs Carburizing Guide.
Screws and Barrels
Barrels are nitrided or bimetallic and screws are tool steel for wear, with surface care in our Surface Treatment Guide and corrosion care in our Corrosion Protection Guide; grade stock is in our Tool Steel Supplier.
Moulds and Platens
Moulds use tool steel and stainless for precise cavities, with machining in our Machining Guide and wear care in our Wear Plate Guide; platens are cast iron or steel for rigidity.
Quality and Sourcing
Mould and screw quality are checked by inspection, with methods in our Quality Inspection Guide; buyers confirm grade via our Mill Test Certificate Guide and pack per our Export Packing Guide.
