Plastic forming is a method of designing, manufacturing, and assembling a product that is made from plastic. Plastic material is used in various ways in our daily life, and the plastic industry is growing daily. According to experts, plastic production may continue to grow and reach 540 million metric tons by 2040. The plastic industry has taken over our kitchens, wardrobes, electronics, and more. Plastic is used in consumer goods, electronics, toys, kitchen appliances, and electrical and industrial machinery.

Plastic Forming

Properties of Plastic

  • Plastics are lightweight and can be molded easily into any shape and size.
  • They are chemically stable, with good rust resistance.
  • Plastic has good insulation and low thermal conductivity.
  • Plastic is transparent and has poor dimensional stability.
  • Plastic material is low–cost and easy to process.

Types of Plastic

There are two types of plastic. These are:

  • Thermosetting Plastic

    Thermosetting plastic, also called thermosets, is plastic that does not undergo any changes in shape once heated and molded. These plastics degrade, deter, and are destroyed on reheating. Common examples are epoxy resin, rubber, polyurethane, etc.

  • Thermoplastic

    Thermoplastic does not change its chemical composition and can be remolded multiple times. Common examples are polystyrene, Teflon, acrylic, and nylon.

Manufacturing Process of Plastic

Plastic forming involves many different processes, and each depends on the type of product and the plastic used. The manufacturing process consists of the following steps:

Plastic Injection Molding

  • This method uses a mold made of aluminum or steel.
  • The mold, consisting of a core and an inner cavity, is placed in the machine.
  • The heated plastic pallets are injected into the molds and then cooled.
  • About 80% of plastic items that we use in our daily life are made by this process.
  • It is a low-cost process that gives an excellent finish, and millions of the same products can be made rapidly.
  • Molds can be expensive, so proper engineering and cleaning are required to prevent mold defects.
Plastic Injection Molding

Rotational Molding

  • In this process, plastic powder is poured into molds and then placed in the ovens.
  • While heating, the mold is rotated slowly on two axes, and gravity is used to stick the powder to the mold walls.
  • The heated plastic is then cooled down slowly to prevent disfiguration.
  • This molding is best for making concave or hollow shapes and large products such as tubs.
  • It is an inexpensive process; the product formed is strong and fault-free.
  • The tools are to be changed after a few thousand cycles, and the method is not best for precision forming.
Rotational Molding

Extrusion Blow Molding

  • This molding is done to make inexpensive products such as disposable cups and bottles.
  • It is a fast process, and the tools are easy to make.
  • Molten plastic takes the form of a large droplet, called a parison, and is placed in a two-piece clamshell mold.
Extrusion Blow Molding

Injection Blow Molding

  • In injection molding, pressure is used to place the molten plastic in the molds.
  • It is used to make transparent plastic bottles and is easily controlled and a repeatable process.
  • These are not ideal for thin walls. However, these are durable and safe to consume.

Reaction Injection Molding

  • RIM is used in the automotive industry as it makes light-weighted parts with rigid skin.
  • Thermosetting plastic expands like foam on heating and fills the mold.
  • Production tooling is expensive for RIM.

Vacuum Casting

  • A master model is placed in a sealed box filled with flexible urethane or silicone.
  • When removed, it forms a cavity in the mold, which is then filled with resin.
  • The air bubbles are removed by using vacuum pressure.
  • These molds are not durable and will degrade after 20 or more copies.
Vacuum Casting


  • A thin or thick plastic sheet is placed on the die, and the rising temperature makes the material pliable.
  • It is used for prototypes of thin-walled and hollow-bodied parts.
  • It is used to make plastic cups, lids, boxes, and plastic packaging.

Compression Molding

  • The raw material used in this process is pre-heated and placed in the cavity.
  • A cap or a plug is used to cover the die, and heat and pressure are applied.
  • It is used to make rubber keypad switches, gaskets, and o-rings.
Compression Molding

Application of Plastic

Plastic material is used in home items such as vacuum cleaners, television, sound systems, chairs, tables, appliances, electronics, utensils, automobiles, space stations, pipes, gaskets, cladding, food packaging, food containers, medical equipment, children safety gears, and many more.
