Where can I use
extrusion plastic tools for? Extrusion
is a manufacturing process where a material, often in the form of a billet,
is pushed and/or drawn through a die to create long objects of a fixed
cross-section. Hollow sections are usually extruded by placing a pin or
mandrel in the die. Extrusion may be continuous (producing indefinitely long
material) or semi-continuous (repeatedly producing many shorter pieces).
Some materials are hot drawn whilst other may be cold drawn.
extrusion plastic tools methods
The feedstock may be forced through the die by various methods: by an auger,
which can be single or twin screw, powered by an electric motor; by a ram,
driven by hydraulic pressure or in other specialised processes such as
rollers inside a perforated drum for the production of many simultaneous
streams of material.
Commonly extruded materials are copper (pipe for plumbing), aluminium
(various extrusion profiles for tracks, frames, rails), steel (rod,
track),rubber,for tire tread and sidewalls and a multitude of plastics
(pipes, rods, rails, seals).
extrusion plastic tools and pultrusion
Plastic extrusion commonly uses plastic chip, which is heated and extruded
in the liquid state, then cooled and solidified as it passes through the
die. In some cases (e.g., fibre reinforced tubes) the extrudate is pulled
through a very long die, in a process called pultrusion.
Extrusion has found a great application in Food Processing. Various products
like pastas, breakfast cereals, ready to eat snacks, fry-ums etc. are now
manufactured by extrusion. Softer foods such as meringue have long been
piped using pastry bags.
Extrusion simulation tools help to understand extrusion process and to
optimize development of tools and products For any information contact
