Hot Shrinking
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. Hot shrinking process Locate the highest point of the panel, light the torch and heat the spot to a cherry red. Strike the area using a mallet around the heat spot. After several blows the sop will turn black, quench it immediately with a damp cloth. Repeat the process around the heated spot until the stretched part became fully shrinked.

Metal
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals ...

Panel Beater
Panel beater or panelbeater is a term used in some Commonwealth countries to describe a person who repairs vehicle bodies back to their factory state after having been damaged (e.g., after being involved in a collision). In the United States and Canada, the same job is done by an auto body mechanic. Description Panel beaters repair body work using skills such as planishing and metalworking techniques, welding, use of putty fillers, and other skills. Accident repair may require the panel beater to repair or replace parts of a vehicle. These parts may be made from various metals including steels and alloys, many different plastics, fibreglass and others. The common panel beater will work on everyday vehicles, cars, vans or 4WDs. Specialised areas include repairs to motorcycles, trucks and even aircraft. Some panel beaters also work exclusively on vehicle restorations, and do not repair smash work at all. Others may specialise in body customisation such as is seen on hot rods. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact that p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Shrinking
Cold shrinking is a process in motor vehicle bodyworks. Compared to hot shrinking, cold shrinking is a longer but nevertheless more preferred method most common especially with larger stretching areas. Cold shrinking is mostly done by use of a dolly hammer. The resulting rough surface is filled using a body filler or a body solder for a smoother finish. Cold shrinking 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 hatchback A hatchback is a car body configuration with a rear door that swings upward to provide access to a cargo area. Hatchbacks may feature fold-down second row seating, where the interior can be reconfigured to prioritize passenger or cargo volume. ...s.

Motor Vehicle Maintenance
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which hea ...
