Match the following products with the suitable manufacturing process
| Product | Manufacturing Process | ||
|---|---|---|---|
| P | Toothpaste tube | 1 | Centrifugal casting |
| Q | Metallic pipes | 2 | Blow moulding |
| R | Plastic bottles | 3 | Rolling |
| S | Threaded bolts | 4 | Impact extrusion |
Answer: C
The correct match is P-4, Q-1, R-2, S-3.
- Toothpaste tubes are made by impact extrusion: a slug of soft metal such as aluminium is struck so that it flows up around the punch as a thin-walled tube (4).
- Metallic pipes are made by centrifugal casting, where the spinning mould throws the metal against its wall to form a hollow cylinder without a core (1).
- Plastic bottles are made by blow moulding, inflating a hot plastic parison inside a mould (2).
- Threaded bolts get their threads by thread rolling (3), which cold-forms the thread and improves its fatigue strength.
Option A gives bottles to centrifugal casting, option B gives toothpaste tubes to blow moulding, and option D gives pipes to rolling and bottles to extrusion.
