Blow Moulding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube until it takes the shape of a Mould cavity. This method is particularly effective for creating products with consistent wall thickness and complex shapes. Developed in the mid-20th century, blow Moulding has become an integral part of many industries, including automotive, packaging, and agriculture. In agriculture, the process has seen significant advancements and is used for making various products, such as containers for pesticides, irrigation equipment, and even large tanks. This blog will explore the blow Moulding technique, its current practices, applications in agriculture, and future perspectives. Blow Moulding Technique: Process and Variants The blow Moulding process involves several steps: 1. Parison Formation: A plastic tube, called a parison, is extruded. The parison is then pl...
Polymers are difficult to classify because there are so many interacting relationship among the large number of polymeric materials now in existence. Four most methods of classifications are 1. Physico chemical structure 2. Mode reparation 3. Physical properties 4. Technical applications A. Physico Chemical structure Functionality: - The ultimate result of coupling monomers to produce polymers is wholly dependent on the functionality of monomer. Molecule is called Mono-, bi-,tri-, or polyfunctional depending on the number of reactive bonds or groups available for coupling at beginning or during course of polymeric reaction. 1. Unifunctional (U-), Exampl...
