Importance of Plastic Extrusion

• Use of plastic has increased manifold in the
  daily life. Either it is for packing food
  material or soft drinks or for industrial piping
  and other uses, plastic is used extensively in
  all sectors. Plastic can be given various shapes
  and sizes conforming to your specific
  requirements using the plastic extrusion method.
  This has turned very advantageous for industries
  as they put great emphasis on consistency of the
  shape, size and quality of the product.

Importance of Plastic Extrusion

• Plastic extrusion process involves melting
  plastic and giving it various shapes by forcing
  it into various dies to give shape of continuous
  of continuous profiles. This is then cut to
  various sizes.
• Using plastic extrusion process we can get final
  product with constant cross sections which are
  perfect for industrial use. Plastic extrusion is
  a great way of achieving standardized sizes which
  are easily workable.

Importance of Plastic Extrusion

• Plastic extrusion is the best way to make low
  cost plastic products at a faster pace and hence
  it yields greater productivity too.
• Plastic extrusion method is used for
  manufacturing products such as piping, plastic
  sheets, weather stripping, wire insulation tapes,
  adhesive tapes, etc.

5
Requirements

• Plastic extrusion can be carried out with the
  help of a simple plastic extrusion machine. The
  main components of the plastic extruder machine
  are hopper, barrel, screw drive, and the screw
  drive motor.
• Thermoplastic material is the basic raw material
  used for the plastic extrusion process. It is
  used in the resin form which is easy to for
  loading and melting.

6
Requirements

• The most common materials used for this procedure
  are high impact polystyrene (HIPS), PVC,
  polyethylene, polypropylene, and ABS.
• For getting the final desired result or dies are
  used. Dies are prepared specifically as per the
  requirement of the shape or size of the final
  product. The accuracy of the die would decide the
  finish and consistency of the final product.

Screw Design- An Important Consideration

• Screw is the only moving part in the plastic
  extruding procedure and hence various factors
  like melting rate, size of the resin, type of raw
  plastic, and amount of pressure required
  maintaining uniformity, etc. play an important
  part in deciding the size, design and diameter of
  the screw.
• Few applications in which materials need to be
  compounded within the barrel of the extruder a
  twin screw design may be used for adequate mixing.

Some Specialized Extrusion Procedures

• One solution fits all can never be fit for
  industrial purposes as every process has a
  definite set of requirements. Some specialty
  extrusion processes are explained ahead
