Cold shrinking

Last updated

Cold shrinking is a process in motor vehicle bodyworks. [1] Compared with hot shrinking, cold shrinking is a longer process, but it is the most preferred method and most common especially where the stretched area is bigger. [2] Cold shrinking is mostly done by use of a dolly hammer. [3] The rough surface is then filled using a body filler or a body solder in order to give a smooth finish. [4]

This is a method of panel beating where heating is not done to the stretched panel. This method is mostly suitable for integral cars with integral body panels such as hatchbacks. [3] [5]

A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a "rotor" to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed.

A chiller is a machine that removes heat from a liquid coolant via a vapor-compression, adsorption refrigeration, or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream. As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes. Vapor compression chillers may use any of a number of different types of compressors. Most common today are the hermetic scroll, semi-hermetic screw, or centrifugal compressors. The condensing side of the chiller can be either air or water cooled. Even when liquid cooled, the chiller is often cooled by an induced or forced draft cooling tower. Absorption and adsorption chillers require a heat source to function.

Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be stretched into or onto a mold and cooled to a finished shape. Its simplified version is vacuum forming.

Hydroforming is a cost-effective way of shaping ductile metals such as aluminium, brass, low alloy steel, and stainless steel into lightweight, structurally stiff and strong pieces. One of the largest applications of hydroforming is the automotive industry, which makes use of the complex shapes made possible by hydroforming to produce stronger, lighter, and more rigid unibody structures for vehicles. This technique is particularly popular with the high-end sports car industry and is also frequently employed in the shaping of aluminium tubes for bicycle frames.

A custom car is a passenger vehicle that has been either substantially altered to improve its performance, often by altering or replacing the engine and transmission; made into a personal "styling" statement, using paintwork and aftermarket accessories to make the car look unlike any car as delivered from the factory; or some combination of both. A desire among some automotive enthusiasts in the United States is to push "styling and performance a step beyond the showroom floor - to truly craft an automobile of one's own." A custom car in British according to Collins English Dictionary is built to the buyer's own specifications.

Bondo is a polyester putty product originally marketed as an automotive body filler. Nowadays the brand name is used by 3M for a line of American-made products for automotive, marine and household repairs. The term Bondo is trademarked by 3M, but is commonly used to refer to any brand of automotive repair putty due to its popularity. It is also used by sculptors.

Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well. Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface.

Conservation and restoration of road vehicles is the process of restoring a vehicle back to its original working condition, whether the car is partially scrapped or completely totaled. Automotive restoration can be applied to many different eras of the automobile. Bus preservation groups aim to purchase buses of various eras to restore them to their original operating condition. Buses are often restored to the original authentic livery of their original owner.

Paintless dent repair (PDR), also known as paintless dent removal, describes a method of removing minor dents from the body of a motor vehicle. A wide range of damage can be repaired using paintless dent repair as long as the paint surface is intact. Paintless dent repair may be used on both aluminum and steel panels.

A solar car is a solar vehicle for use on public roads or race tracks. Solar vehicles are electric vehicles that use self-contained solar cells to provide full or partial power to the vehicle via sunlight. Solar vehicles typically contain a rechargeable battery to help regulate and store the energy from the solar cells and from regenerative braking. Some solar cars can be plugged into external power sources to supplement the power of sunlight used to charge their battery.

Hot shrinking is a process in car bodyworks. As the name suggests, heat will be involved, while "shrinking" is the process of straightening a metal section. This is a method of panel beating where a panel is first heated to make it softer. In most cases, heating will be done by use of the oxyacetylene flame.

Beaten coffee or phenti hui coffee or phitti hui coffee is an Indian home-style coffee beverage made mostly with instant coffee and sugar. It is known as 'beaten' as the process involves beating the coffee and sugar together with a spoon to aerate into a light brown fluffy paste-like substance. It is generally served with warm milk, which creates a thick froth on the top. Another popular way of serving it is by pouring the paste on top of a cup of warm or cold milk. Beaten coffee can be prepared without any special machines or coffee mixes. Coffee is beaten with milk, hot water, and sugar, incorporating air into the paste until frothy. As milk is added, the coffee is further dissolved and air is released creating a creamy texture. This method of hand-beating is what gives the coffee the name "Beaten Coffee".
