Hydro Drive
Hydro Forming uses water pressure to form complex shapes from sheet or tube material. The pressure may go up about 60,000 psi depending on the component.
As the automobile industry strives to make car lighter, stronger and more fuel efficient, it will continue to drive hydro forming applications. Some automobile parts such as structural chassis, instrument panel beam, engine cradles and radiator closures are becoming standard hydro formed parts.
The capability of hydro forming can be more fully used to create complicated parts. Using a single hydro formed item to replace several individual parts eliminate welding or hole punching, simplifies assembly and reduce inventory.
Taking Advantage Of Hydro Forming
When considering hydro forming, companies need to ask whether this technology will make a part cheaper to produce. The real question is whether you can refine the entire manufacturing process to take advantage of hydroforming that is when it really makes.
Instead of looking at a single competent to determine whether it can be hydro formed , companied need to look at a product through whole process, from material to assembly , to determine what savings can be achieved . For e.g. Hydro forming often reduces number of pieces or the amount of floor space used or eliminates the need for welding stations.
Methods Of Hydro Forming
Tube Hydro forming
Straight, pre bent and or performed tubes are formed by internal water pressure with additional application of compressive mechanical forces. In this method the tube in placed in die and as press clamps the die valves, low pressure fluid in introduced into tube to pre form it.
One the maximum clamping pressure in achieved, the fluid pressure inside the tube in increased so that tube bulges to take internal shape of the die. Simultaneously additional cylinders axially compress the tube to prevent thinning and brushing swing expansion.

During the last 12 years, general awareness of hydro forming has grown steadily . Although interest in hydroforming is wide ranging , the vast majority of application are in automobile industry .
Hydro forming is the process by which water pressure is used to form complex shapes from sheet or tube material.Applications of hydro forming in automotive industry are gaining globally in popularity. The trend in auto manufacturing of making parts lighter and more complicated with necessary strength reinforcement only where required is on the rise. The capability of hydro forming is more fully used to produce such complicated parts.
Hydro Forming is not panacea for manufacturing all automotive parts. The benefits of automotive light weight resin and weight reduction achieved by hydroforming can be measured in kilogram. It cannot be applied to every components, one has to study inability of hydro forming the part and the economic and technical payback. Just like transistor revolutionized the electronic industry, hydro forming has taken the vehicle manufacturing industry a step up to evolutionary ladder, allowing auto component for vehicle . Although hydroforming has not taken off rapidly as it should have , is only matter on time before this technology is absorbed in the industry ..

Hydro Drive is a drive or transmission system that uses hydraulic fluid under pressure to drive machinery. The term hydrostatic refers to the transfer of energy from flow and pressure, not from the kinetic energy of the flow.consists mainly of three parts. The generator (e.g. a hydraulic pump, driven by an electric motor, a combustion engine or a windmill); valves, filters, piping etc. (to guide and control the system); the motor (e.g. a hydraulic motor or hydraulic cylinder) to drive the machinery
