Aluminum Hydraulic Cylinder Housing
Aluminum Hydraulic Cylinder Housing

A customer in the automotive industry contracted us at Whitehall Industries to manufacture custom hydraulic cylinder housing for use in convertible tops and rear hatch applications in a variety of vehicles. Our SMS Sutton 2000T extrusion press was employed to extrude high precision aluminum to the customer specified profile, specialized fabrication methods utilizing our Hydromat 12 station vertical trunion to detail and finish the parts. The tightest tolerance of 18 microns for drilled holes was met during manufacturing. The high strength aluminum alloy used for the housing is able to handle hydraulic pressures of up to 2250 psi as required. Whitehall is able to provide very precise ID bore tolerances directly from their extrusion operation without any secondary machining. Dimensions of finished housings range from 75mm to 200 mm in length, an inner diameter of 12mm to 25mm, and have a wall thickness of 2mm and a surface finish of Ra 1.60/Rmax 10.

Comprehensive post production and in-process testing and inspections were carried out to assure accuracy and integrity, implementing methods including flare testing, burst strength testing, and testing to failure. This part is serial produced with 30,000 to 40,000 units manufactured per week. Orders are specially packaged and shipped to locations worldwide.
