These days high quality plastic extrusion profiles are made from a wide range of materials. Extruded Plastic profiles comes in a wide variety of shapes,
colour and sizes. Modern extrusion machine lines can handle tubes that has a diameter of 160 mm and profiles that are 350 mm wide. Let's have look
at the choice of plastic materials for extruded profiles. The image here shows some of the popular extruded plastic profiles.

Buyers Guide for Design Consideration in Extruded Plastic Profiles

A good design of the extruded plastic profiles should ensure cost-effectiveness, uniform good quality etc. The following design tips may prove to be
useful for designing a plastic extrusion. Ideally from the design point of view, design considerations can be broken down to two parts. They are the
following:

Basic Die Design

• Flat Plate Die
  Plate that has the shape of the part cut through a die. There is no transition to guide the material. This low cost design is suited ideally for low
• volume production runs.
  
   
• Semi-streamlined Die
  At the back of the die the edges and corners have radii to help the material transition into the die.
  
   
• Fully Streamlined Die
  The die is able to aggressively channelize the plastic material throughout the die in an even manner. This design however is not cheap so ideally
suited to high production runs.

Part Design

• Consistent Wall Thickness
  Coming to wall thickness, of the profiles, an uniform wall thickness is one of the most vital aspect in the design of the part. It permits an even flow
• of material through the die. Thus resulting in more controlled parts along with a lower tooling expenditure.
  
   
• Hollow Section Design
  Ideally designing of profiles with hollow sections should be avoided. They are known to add significantly to the cost of the part as well as the tooling.

Design Tips for Co extruded Profiles

• A dual extrusion for the shape of a modular cabinet wall panel.
  
  
   
• In case flexible sealing portion wears out due to abrasion, a flexible insert can then be slid into the rigid plastic slot as a replacement.
  
  
   
• Common dual extrusions of rigid and flexible PVC.
  
  
   
• Cross section of a window frame that has a metal embodiment.
  
  
   
• Applications for metal embodiment extrusions.

Industrial Applications of Extruded Plastic Profiles

Some of the critical industries that use extruded plastic profiles are highlighted here

Extruded Plastic Profiles in Medical Industry

In the medical industry extruded plastic profiles are used in the following segments. They are medical device components, medical instruments and
medical processing aides. Let's take a look at the products now.

• Extruded Tubing
  A wide range of plastic extruded tubes today are used in critical medical applications. In medical industry adhering to tight tolerances for the extruded products is an absolute must. Extruded Medical Tubing are produced in various shapes that includes rectangular, round, square, triangular etc. Products that are extruded and co-extruded includes:
  • Single lumen tubing
  • Multi lumen tubing
  • Multi layered tubing
  • Thin wall tubing
  • Dual wall tubing
  • Surgical Tubing
  • Medical catheter Tubing

• Extruded Plastic Profiles in Automotive Industry

  In the automotive industry there are many instances of use of extruded plastic profiles. The following image gives an overview of the extent to
which plastic extrusion is a compulsory feature in automobiles.

Some of the popular extruded profiles as used in automobiles include:

• Fuel resistance Tubes
  Some of the advantages associated with extruded fuel resistance tubes includes: resistance to flames fuels and liquids, operating capability in
high temperatures, low temperature flexibility.


• Extruded Plastic Trims
  Edge Trims are used in a car and truck doors. Options in the form of adhesive also comes with the Extruded Trims. Some popular shapes of edge
trims are shown here:

Extruded Plastic Profiles in Building Industry

Extruded Plastic profiles are used extensively in the building industry. Plastic siding profiles have a global use. Some of the profiles used are office furniture,
partitioning profiles Nozing, False Floor Beading, Thermal Breakers, fencing, decking, siding, bevelled Skirting, Thermal cover, Cove Track etc. Window
profiles are also very popular.
