Cheap Extrusion Molding
Cheap extrusion molding frequently uses plastic potato chips or pellets, which might be usually dried in the hopper before going to the feed attach. The polymer resin is actually heated to molten state by a variety of heating elements in addition to shear heating in the extrusion screw. The screw makes the resin through a die, forming the resin in to the desired shape. The extradite is actually cooled and solidified precisely as it is pulled in the die or mineral water tank. In some situations (such as fiber-reinforced tubes) that extradite is pulled through a very long cease to live, in a method called pultrusion.

A multitude of polymers are employed in the production tooling regarding plastic tubing, pipes, rods, rails, seals, in addition to sheets or videos.

Cold Extrusion Molding
Cold extrusion molding is conducted at room heat or near bedroom temperature. The features of this over hot extrusion will be the lack of oxidation, higher strength thanks to cold working, better tolerances, good surface finish, and fast extrusion speeds if the material is at the mercy of hot shortness.

Materials which might be commonly cold extruded incorporate: lead, tin, light weight aluminum, copper, zirconium, titanium, molybdenum, beryllium, vanadium, niobium, in addition to steel.

Examples of products made by this process tend to be: collapsible tubes, hearth extinguisher cases, zap absorber cylinders, auto-grade pistons, gear blanks for example.
