Match the following polymer product with its most appropriate processing technique
Show Hint
Injection blow molding is used for hollow parts like bottles, thermoforming is for packaging materials, pultrusion is ideal for creating continuous reinforced shapes, and extrusion is used for continuous shapes like pipes.
- P. Bottle: The production of bottles, especially plastic bottles, is commonly done using Injection blow molding. This technique allows for the precise molding of hollow plastic products such as bottles. Hence, the correct match is: P-3.
- Q. Blister packaging: This packaging technique involves forming plastic around a product, which is a typical application of Thermoforming. In thermoforming, plastic sheets are heated and then molded over a product. Hence, the correct match is: Q-4.
- R. Reinforced electric poles: These poles are often produced using Pultrusion, a process that creates continuous lengths of reinforced polymer. Pultrusion is ideal for manufacturing products that require high strength like reinforced poles. Hence, the correct match is: R-2.
- S. Sewage pipes: The most appropriate technique for producing large pipes such as sewage pipes is Extrusion, where material is forced through a mold to create continuous shapes. Hence, the correct match is: S-1.
Thus, the correct pairing is P-3; Q-4; R-2; S-1.
