Machine tools provide an effective and efficient method for manufacturing critical components with ease and accuracy. These tools help to cut and shape metals and other materials based on the required product specification. The main component in a machine tool is the spindle, in which tools or inserts are attached for the precision machining of components. Machine tools can work under either CNC or manual work conditions. CNC machines work on the M and G codes. These programs control the tool path, spindle movement, feed rate, tooling, and other spindle and bed operations. Machine tools are used in a number of industries, including Automotive, Shipbuilding/Railway, Energy, and Aviation.The Machine Tool market in China is a steadily growing engineering market. The market is dominated by East China and is followed by North China. The market is expected to witness an improvement in its growth rate and post a CAGR of 8.16 percent during the period 2012-2016.

An elevator is a lowering or hosting mechanism which has been designed to carry passenger or freight between the floors of the building. The device inculcates a car and platform which typically moves in the vertical direction.The elevator has been classified into two types such as electric traction and hydraulic elevators.Global elevators and escalators industry has showcased favorable trend in the last five years. However, the growth trajectory of the elevator and escalators industry has been restrained in 2009 on account of the down trend in the demand of elevators and escalators in the global market. The decrease in the requirement of elevators and escalators is affected by the decline in the construction industry in the world.

Heat pumps are devices that extract heat from the outside environment (heat source: air,ground and water) and transfer it to a heat sink. They can cool and heat the inside environment using the same refrigeration system. There are several types of heat pumps such as air source heat pumps, ground source heat pumps, water source heat pumps, and composite heat pumps. These heat pumps are installed across a spectrum of buildings such as Commercial buildings, Information Technology (IT) Parks, Hotels, Restaurants, Manufacturing Industries, RetailOutlets, Public buildings, and Residential buildings for enhanced lifestyle comfort.The Heat Pump market in China is one of the fastest growing engineering markets in the country.The Heat Pump market in China is highly competitive with the presence of several local and international vendors. Some of the prominent vendors in the market are Daikin Industries Ltd.,Sirac Air Conditioning Equipments Co. Ltd., Trane Inc., and Gree Electric Appliances Inc. The market is expected to witness an improvement in its growth rate and post a CAGR of 27.66 percent during the period 2012–2016.

A diesel engine is a machine that converts chemical energy into mechanical energy by the method of high-pressure internal combustion. Mechanical energy enables the movement of pistons in a cylinder in the diesel engine, which in turn facilitate the movement of a crankshaft. A diesel engine is composed of several components such as fuel injector, piston, connecting rod, crankshaft, and combustion chamber. Unlike petrol engine, diesel engine does not have a spark plug for igniting the fuel. Diesel engines are used in several industries such as Automotive, Aerospace, Shipbuilding, Machinery, and Locomotive. In addition, these are increasingly used for power backup. Diesel generators are also deployed across residential, commercial, and industrial buildings for uninterrupted power supply. Diesel generators are incorporated with agenhead that produces electrical output from mechanical energy developed in the engine and works under the principle of electromagnetic induction, generating electric current from diesel engines.
