#01 / Bentley Arnage – Stretch Vehicles

We are proud of our long standing relationship with Bentley, supplying them with Body in White vehicles – fully stretched and ready for paint.

Our full vehicle bespoke service caters for the many variances during the manufacturing lifetime of the Arnage. Variant vehicle lengths require all doors to be remanufactured, stretching both the front and rear doors enabling a style line between them that could encompass all lengths. All tooling is manufactured on-site in steel or cast iron. All tools were designed and manufactured using Autoform simulation, ensuring the feasibility of all new part and tool designs. The build fixture was designed and manufactured to be flexible.

We have currently supplied over 700 bespoke Arnage BIWs straight into paint at Bentley.

#02 / Jaguar Land Rover - Prototyping

It has been a privilege to work with Jaguar Land Rover (JLR) for more than half our company life! We have an established partnership with JLR for prototyping and fast response problem resolution. More recently, the relationship has evolved to add strength and depth to the partnership through:

  • Low volume production proven in automotive and aerospace
  • Enhanced facilities and streamlined systems
  • Relocation and strategic development

The new XJ is a recent testament to the strength of our ‘special’ relationship with JLR. Manufacturing every single panel, including the closures, closure assemblies, superstructure and underbody, it demonstrates our expertise in aluminium and validates our low volume production capabilities.

#03 / Nilsson Vehicle Company - Specialist Vehicle

Nilsson Special Vehicles is a special vehicles company, manufacturing limousines, ambulances and hearses. We were tasked with manufacturing prototype and production panels and assemblies for the Volvo S80 and V70 range of vehicles consisting of a Hearse and limousines of varying lengths.

We reverse engineered the finished prototype vehicles. Digitally scanning the finished prototype vehicles a CAD file was created for all new BIW panels and assemblies. We then created machining data for tool manufacture and laser & inspection files.

Laser scanning was used for creating the full CAD file and also for the final part inspection reporting. Autoform press simulation was utilised for the feasibility of parts and the proving of all manufactured press tooling. Patterns and tools were cut using CNC milling stations and pressed parts were 3D Laser cut.

What thickness of materials can you laser cut?

Mild Steel: up to 20mm
Stainless Steel: up to 12mm
Aluminium: up to 8 mm

What is pressing?

Pressing (also known as stamping) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape.

What is a press brake?

A press brake is a special type of machine press that bends sheet metal into shape. It is one of the oldest mechanical metal deformation processes. During the process, a piece of sheet metal is formed along a straight axis. Precision bending is a function of both the press, the toolingand the work-piece material. Material properties such as yield strength, ductility, hardness, and the condition of the material, all affect the amount of spring back of the material. The most common industrial press braking process is called air bending.

What is laser cutting?

Laser cutting is a way to cut precise patterns in a material. Traditionally, the material has been metal (aluminium, copper, brass and titanium), but it can be any material – plastic, wood, leather to name a few. It allows a level of accuracy and complexity impossible with conventional machining tools. When cutting stainless steel or aluminum, the laser beam simply melts the material, and high pressure nitrogen is used to blow the molten metal out of the kerf. On a CNC laser cutter, the laser cutting head is moved over the metal plate in the shape of the desired part, thus cutting the part out of the plate.

Laser cutting machines are integrated into a larger CAD/CAM (computer-aided-design, computer-aided-manufacturing) system that takes a design file and implements it on a workpiece. These machines represent a stepping stone in the continuing trend away from hands-on manufacturing, putting human workers in a more removed, creative design role.
