Blast and peening solutions for the Automotive Industry

Wheelabrator's Extensive Automotive Experience

A great number of our largest customers come from the Automotive sector, and many of our innovations and product developments evolved from designing solutions for this rapid-development industry.

Automotive manufacturers are constantly striving to make their components, stronger, faster and/or lighter with strict cost restraints. Wheelabrator works with the OEMs and their suppliers to support them in this quest to strengthen, clean and polish parts to improve performance.

In addition to developments in the surface finishing and shot peening processes, Wheelabrator invests a great deal of time and effort in the research and development of complex materials handling and automation, in order to develop truly integrated in-line solutions to fit in today’s production lines.

Wheelabrator specialises in custom-designed shot peening and surface preparation solutions to provide a solution to your challenges. With global innovation) and global machine support, we can support your peening and surface preparation needs.

Similarly, we have used our experience gained from the design and manufacture of 1000's of blast machines to create a full range of "standard" machines.

Brakes

Traditionally brake discs have been desanded and cleaned direct from the foundry's cooling process in continuous through feed machines, a type of tumble blast machine.

But as automotive parts are becoming more sophisticated and valuable, many automotive manufacturers and suppliers are choosing to desand and clean discs in a manner where there is no part-on-part contact, and without the tumbling action. This can be achieved in inclined belt machines, where the brake disc is held in a vertical position and blasted from both sides whilst gently passing through a continous machine.

Engine

Engine castings in iron and light metals such as aluminium need to be cleaned of sand and deburred, internal bores need cleaning, and sometimes a surface finish is required in preparation for subsequent processes.

Gears

Gear and transmission components can be shot peened to increase the resistance to fatigue. These components can be shot peened by either wheelblast or airblast technologies, and the best solution will depend on your application, quantities and production processes.

  • Drive shaft, Gear shaft, Reverse Lock,
  • Outer Disc Carrier, Switching Piston Valve Plate,
  • Camshaft Drive Chain Plate, Gear Housing,
  • Parallel Feed Body, Sliding Coupling,
  • Epicyclic Gear, Housing, Central Gear

Shot Peening Process Benefits:

  • Increase fatigue strength by at least 60%. In fully controlled conditions, it is possible to more than double the fatigue strength.
  • Increase bending strength.
  • Delay crack and micro-fissure formation in highly stressed components as the compressive stress prevents initiation and propagation.

Superfinishing Process Benefits:

  • Low Ra finish, which can improve life of the part by as much as 30% for metal to metal contact.
  • Noise and vibration reductions.
  • Operating temperature reduction.
  • Wear and pitting reduction.

These benefits will lead to longer lasting and better performing components.

wheel rim  Wheel Rim Deburring Rotary Table and Continuous Rotary Table Machine
Aluminium wheel rims are blasted to achieve a homogeneous and burr-free surface in preparation for subsequent powder coating. Rotary Table machines are used for special rims and low capacities (cycle around 2-3 minutes) and line integrated Rotary Table machines, working in cycles of around 15 seconds. The continuous rotary table machines are available in single or double strand versions.
