CHECK WHY BOTTLES HAVE INDENTS AT THE BASE ???

You might have noticed the huge indents under glass bottles, but they are not simply to add style or support. These are the reasons :-

1.They help distribute pressure evenly when the bottle is being corked, which is why champagne bottles have the deepest indents.

2.To disperse the sediment, and hinder it from rising up when poured.

3.The large indent in the base of wine bottles is known as a punt. It is intended to strengthen the bottle.

4.To create the optical illusion that the bottle is bigger of course. Cosmetics manufacturers have taken this technique several steps further.

DIFFERENCE BETWEEN ALIGNMENT AND BALANCING EXPLAINED !!

Alignment and balancing are two words that we hear too often whenever we go for a servicing of our car but very few understand the difference between the two. These are closely related concepts that make sure that you are safe while driving and do not face a mishap on road because of faulty alignment of tires or if the balancing of tires is not perfect. Let us clarify the two concepts so you know what you need when there is any trouble with the wheels of your car.

Balancing

Balancing is necessary as with constant rotation, tire becomes unbalanced. Out of balance tires cause vibration of the vehicle, and at higher speeds, the risk of a mishap greatly increases. Balancing of tires is therefore imperative after every 12-15 thousand miles of run. Balancing also ensures that your tires have a longer life as wear of tires is greatly reduced with balancing.

Alignment

All tires of a new car are perfectly aligned which means that they all point in one direction. This ensures that no tire unduly pushes out or pulls inward causing trouble for the vehicle. If the wheels are perfectly aligned the tires not only have a longer life, you also get better mileage. This also eases pressure on the suspension of the automobile, and in general gives more driving pleasure.

Difference between Alignment and Balancing

Though balancing and alignment are different, they have a bearing on the state of the car which is low mileage and an increased probability of a mishap. Wheel balancing is done on an automated machine which corrects minor imbalances of wheel assembly. On the other hand wheel alignment is a process that ensures that angles of caster, camber and toe are correct. In simple words, it makes the tires point in a single direction.

In brief:

• Alignment and balancing are important for your safety and wear of the tires of your car

• Balancing corrects any imbalance of tires or wheels while alignment ensures that your wheels point in the same direction

• If both wheel balancing and alignment are regularly done, tires have a longer life and you get more mileage from your car

IMPORTANT TERMS OF MANUFACTURING PROCESS EXPLAINED !!

1.)BUTT-WELDING – Form of electrical resistance welding, the passage of current between the ends of the sections to be joined causing a rise in temperature sufficient to fuse the metal.

2.)CALENDERING – A process that involves rolling of the product into sheets to achieve the desired surface finishes and thickness.

3.)CASTING – Process of producing a metal object by pouring molten metal
into a mould.

4.)COINING (embossing) – Shaping a piece of a metal in a mould or die often creating raised figures or numbers.

5.)COLD DRAWING – Reducing the cross section of a metal bar or rod by drawing it through a die, at a temperature below the recrystallization range, usually room temperature.

6.)COLD ROLLING – Reducing the cross-section of a metal bar in a rolling mill below the recrystallization temperature, usually room temperature.

7.)COLD SAWING – Any sawing process in which the chips are not heated to the softened state.

8.)COLD WORKING – Deforming a metal plastically at a temperature below its lowest recrystallization temperature. Strain hardening occurs as a result of this permanent deformation.

9.)ETCHING – Process of marking a metal by eating into it with an acid or other chemical.

10.)EXFOLIATION – Cracking of the outer skin of the metal.

11.)EXTRUSION – Process in which metal (often heated) is caused to flow through a restricted orifice by using an extremely high force, so creating an extremely elongated strip of uniform, but comparatively small cross-section.

12.)FLASH WELDING – Method of electric resistance welding of sections of material by the formation of an electric arc between the edges of the pieces to be joined and then pressing together with a light pressure the molten edges.

13.)FLATTING – Finishing operation carried out at the end of the work cycle to remove the various hammer marks on the surface left in by the previous shaping operations.

14.)HONING– Process whereby a mirror finish is given to important bearing surfaces by using hones or abrasive tools that normally employ both rotary and longitudinal motion.

15.)IMPACT EXTRUSION– In this process, a slug of metal is placed on a solid bottom die, and the impact of the punch causes the metal to flow back over the punch, which has a uniform section, slightly relieved.
