Hydraulic Presses in the Aerospace Industry

Hydraulic presses are widely used to fabricate products such as airplane body panels and wings. In the automotive industry, they're employed for gear assemblies and windshield wiper blades.

A hydraulic press works by transferring the pressure of a fluid from one smaller piston to another. This creates an correspondingly larger mechanical force and causes the cylinder to compress.

Metal Forming

Metal forming with a hydraulic press is an efficient method for producing high-quality parts for the aerospace industry. It can be applied to various metals and material thicknesses.

Hydraulic presses are mechanical devices that employ Pascal's law to generate the force necessary to shape materials. In a press, a large cylinder (called the ram) is connected to a smaller one (known as the plunger), creating pressure when depressed.

Hydraulic presses use non-flammable oil as their fluid, providing lubrication to protect them against rusting. Furthermore, this lubricant improves transmission efficiency and guarantees long-term work performance.

A hydraulic press operates with a straightforward system, featuring one cylinder that holds the ram and another for the plunger. Both components are connected by pipe that runs through the press and empties into a reservoir of liquid.

Plastic Forming

A hydraulic press is used to form plastic by applying pressure against a sheet of material. These presses can either be operated manually or electrically; the mechanism consists of a cylinder producing pressure, reservoir for fluid to be pressed against and pump providing power to the cylinder.

In a hydraulic press, there is a valve that regulates fluid flow to maintain consistent pressure levels. Additionally, this helps control the press' speed and force.

There are various types of hydraulic presses:

Compression molding is the most widely used type, using heated materials to produce precision parts with excellent physical characteristics. This process has found widespread application in automotive, aerospace and medical industries due to its ability to produce complex shapes with superior accuracy and strength.

Deep Drawing

Deep drawing is a metal forming technique that involves pushing a sheet metal blank into an aluminum die cavity, producing contoured parts with at least half the width or diameter of the original metal.

Deep drawn parts are commonly made from aluminum alloy or low carbon steel due to their superior strength, light weight, ductility, and corrosion resistance.

The forming process is energy efficient, which reduces waste and production expenses. Furthermore, it contributes to environmental protection efforts.

Additionally, this machine can produce precise shapes and sizes that are essential in industrial manufacturing. It finds application across a variety of sectors such as aviation and aerospace.

Assembly

Hydraulic presses are widely used in the automotive industry to fabricate components. Many car parts such as switches, housings and thermostats are formed using hydraulic presses.

Hydraulic presses can also be employed in the assembly of household appliances like dishwashers and microwave ovens. These machines produce complex shapes with less risk of tear or wrinkle damage to material.

Utilizing a hydraulic press to assemble parts is advantageous for manufacturers as it saves them time and ensures consistent quality throughout the assembly process. This is especially beneficial when creating products with complex shapes or requiring high precision.

A double action deep drawing press is ideal for this application as it uses two cylinders to generate the force required for a deep draw. This provides manufacturers with more consistent results and reduces the chance of material wrinkling or tearage.
