Common Production Process of Polymer Companies
Indian Polymer Industries produce a wide range of polymer products using various production processes. Some industry used common production processes are elaborated below.
Injection Molding: This is a popular production process used to manufacture polymer products with complex shapes. It involves melting the polymer and injecting it into a mold under high pressure. The mold is then cooled, and the solidified polymer is removed. Injection molding is suitable for producing large quantities of products with high precision and repeatability.
Extrusion: This is a continuous process used to produce products with a constant cross-section, such as pipes, tubes, and profiles. The polymer is melted and forced through a die to create the desired shape. Extrusion can be used to produce products with simple or complex shapes and can be customized to meet specific requirements.
Blow Molding: This process is used to manufacture products with hollow cavities, such as bottles, containers, and automotive parts. It involves heating a polymer tube to its melting point and using air pressure to blow it into a mold. The mold is cooled, and the solidified product is removed. Blow molding is suitable for producing large quantities of products with consistent quality.
Thermoforming: This is a cost-effective production process used to manufacture products with complex shapes. It involves heating a sheet of polymer to its melting point and forming it into the desired shape using a mold. Thermoforming is suitable for producing low to medium quantities of products with moderate precision.
Rotational Molding: This process is used to manufacture products with complex shapes and thin walls, such as fuel tanks and toys. It involves heating a powder or liquid polymer in a mold rotated on two axes. The heat and rotation cause the polymer to evenly coat the walls of the mold, forming the desired shape. Rotational molding is suitable for producing medium to large quantities of products with moderate precision.
Compression Molding: This process is used to manufacture products with a high degree of accuracy and repeatability. It involves heating a pre-shaped polymer to its melting point and placing it in a mold under high pressure. The mold is cooled, and the solidified product is removed. Compression molding is suitable for producing medium to large quantities of products with high precision and repeatability.
Transfer Molding: This process is similar to injection molding, but the polymer is pre-heated and placed in a pot. The pot is then pressurized, and the polymer is injected into the mold. Transfer molding is suitable for producing small quantities of products with high precision and repeatability.
Casting: This is a simple and flexible production process used to manufacture products with complex shapes. It involves pouring a liquid polymer into a mold and allowing it to solidify. Casting is suitable for producing small quantities of products with moderate precision.
In addition to the production processes mentioned above, Indian Polymer industries may also use a combination of these processes to manufacture their products. For example, we may use injection molding to produce the main body of a product and then use thermoforming to add additional features.

We carefully select the appropriate production process based on the product’s design, production volume, and required precision. The choice of the production process can significantly impact the cost and quality of the final product. It is essential for polymer companies like us to optimize their production processes to ensure efficiency and competitiveness in the market.
