What do you need to Know about Manufacturing Plastics?

Plastic is among the most commonly used materials for the production of a wide range of products. Different manufacturing processes are implemented to manufacture based on the type of plastic, applications, and geometrics. In this guide, we will be sharing everything that you need to know about the manufacturing of plastic.

Types of Plastic:-

 Primarily, two types of plastic available include:


 Thermoplastics can go through multiple stages of melting and solidification without being degraded. Additionally, these materials are generally supplied as small sheets or pellets heated and solidified in the desired shape for multiple purposes. It is an entirely reversible process because no chemical restrictions are happening.

Some types of thermoplastic materials are:-

  • Acrylonitrile butadiene styrene (ABS)
  • Polyether ether ketone (PEEK)
  • Acrylic (PMMA)
  • Polyvinyl chloride (PVC)
  • Polyamide (PA)
  • Polyethene (PE)

Thermosetting Plastic

Contrary to the thermoplastics, the thermosetting plastics tend to become permanent after they reach a solid-state. They are also known as thermosets, and polymers are corssed0lined during the melting and curing process that is generated by heat, radiation or light. The curing process of these types of materials is irreversible. Moreover, thermoset plastics get decomposed when heated and don’t reform after cooling. Some common examples of thermosetting plastic include:

  • Epoxy 
  • Polyester 
  • Cyanate ester 
  • Silicone 
  • Vulcanized rubber

Manufacturing Plastics

Types of Manufacturing Processes:-

Following are some popular types of the manufacturing process of plastic that are often used by the plastic manufacturer in Odisha and the rest of the nation:

 3D Printing

 In this process, three-dimensional parts are created from the CAD models by forming the material layer by layer until the shape is completely built. It only requires minimal set-up with no additional tool; therefore, the cost of this manufacturing process is quite low.

 Polymer Casting

 In this method, a reactive liquid resin if filled in a mould forms a chemical reaction and gets solidified. Generally, epoxy, silicone, polyurethane, etc. are used for this process. While it is an inexpensive way to manufacture plastic, it can produce a limited number of casting.

 CNC Machining

 CNC machining comprises of lathes, mills, and many other subtractive processes that are controlled by computer. In this method, the materials are shaped by cutting, drilling, grinding, boring etc. this process is ideal for applications that need tight tolerances and intricate geometrics.

Rational Moulding

Rational moulding, also known as rotomoulding includes heating a mould that is filled with powdered thermoplastic and rotating it for two axes to generating mostly hollow items. Considering that no pressure is needed to fill the mould, it is a secure and expensive form of manufacturing.

Different types of plastics are manufactured in different ways, depending on various factors. The manufacturers must choose the right production method that caters to the needs of the end-object.
