We can provide products as diverse as cylindrical preforms for flow forming to finish machined
components ready for assembly

 

Hollow Extrusions has been providing a wide range of components to the defence industry for over 50 years.

Hollow Extrusions has a proven track record in contributing to the development of projects from the earliest stages through to full production.

The central elements of our process are warm and cold extrusion. This method provides a single piece component with a high level of integrity and excellent performance under stress. This is often vital in defence applications.

QUALITY

A significant revamping of the Quality Department has been focused on attaining the ISO 9001 2000 standard. This has had significant benefits in all areas of the business where the importance of Continuous Improvement and Customer Satisfaction is well recognised.

We can provide a broad range of materials testing, offering a level of confidence and traceability which is critical in defence products. Alongside this assurance of quality we offer design assistance and technical support to ensure that our process is best utilised to supply the customer's requirements.

 

PREFORMS

The flow forming process is frequently the ideal way to produce long pieces with particularly thin walls. An extruded perform can be produced to the very close tolerances required by flow forming. This option offers significant advantages over the machining alternative, which wastes more of what is often very expensive material.

   

MUNITIONS & MISSILE CASINGS

 

Control of material in terms of both grain flow and properties is an important aspect of the production of munitions. Our process will allow manipulation of these aspects to provide the maximum strength/weight ratio. We are able to offer finished bores in heat treated condition as well as a variety of complex shapes.

 

HYDRAULIC CYLINDERS

Hollow Extrusions have produced finish machined hydraulic cylinders for a number of years. Once again the single piece construction ensures high strength and excellent performance under stress. This makes our cylinders particularly suited to specialist defence vehicles.

 

ROCKET MOTOR BODIES

The integral base provided by an extrusion is critical in applications of this type where safety is utterly paramount. The range of materials and heat treatments which we are able to offer provides significant flexibility to our customers
