VAVE optimization in the automotive industry: Identifying competitive advantages during product development and series production

September 29, 2021 Sebastian Bloechl

What is VAVE, and how can it be used?

VAVE (Value Analysis/Value Engineering) is an effective method of improving technology, optimizing processes and reducing costs. In the automotive industry, with its focus on efficiency and quantity, VAVE project implementation is the order of the day.

VAVE has a long history and is associated with powerful insights. In the 1940s, engineers discovered that replacing conventional materials and components delivered significant benefits for the final product.

What started as a necessity caused by scarcity of goods became a systematic process and a highly innovative tool. The approach has been steadily refined over the years. Value analysis became value engineering, which in turn became comprehensive value management. Today, VAVE is a fixed component of cost reduction measures for products.
 
But it is not always easy to replace product components or to find the right replacement product with a VAVE background. igus offers various options to obtain free samples of VAVE-optimized plain bearings. More information about this process can be found in the last section of this article.

VAVE background at igus

“Give me your most difficult part and I will find a solution”, was the challenge igus founder, Günter Blase, issued to Pierburg, an automotive supplier, in 1965.
 
At the time, no one had come up with the idea of using plastic to make a small metal component, much less doing so with an injection molding machine. This was due in part because the manufacturing process was complicated. For Günter Blase, however, this barrier was no reason to lose hope. He went into his double garage and experimented until the first perfect plastic plug valve emerged from his injection molding machine. The result was a plastic part that gave Pierburg a longer service life for a lower cost than the commonly used metal plug valve.
 
We still follow this approach and have summarized it in our motion plastics® slogan: Tech up, cost down. It’s our job!®

VAVE in igus products

Cost down ↓

  • Costs 40% less than conventional bearing solutions
    • Large selection of materials for the ideal VAVE solution, including plain bearings
    • Greater savings with replacements for components such as stainless steel composite bearings, ceramic bearings and graphite-carbon bearings
    • Cost-efficient manufacturing methods including micro injection molding: low cycle time, less material for cutting and cold distribution, smaller machines, less power consumption and improved sustainability
  • Component reduction: replace solutions with a one-piece plastic part
  • Self-lubricating: no external lubrication necessary
  • Save on installation time and process steps with improvements such as innovative designs of our clip bearings

Tech up ↑

  • Weighs up to 80% less
  • Noise reducing
  • Low wear and coefficient of friction
  • Self-lubricating: no external lubrication necessary
  • Reduces emissions
  • No corrosion
  • Longer service life of the application
  • Vibration-dampening
  • High chemical resistance
  • Design freedom
  • Easy assembly
  • Improved CO2 footprint

Value engineering for applications in vehicles

igus products can be found wherever there is motion. Our products reduce friction, wear and noise in automotive applications. From pedal mount to windscreen wipers to car seat adjustment mechanisms, from plain bearings and gears in actuators and small motors to high temperature ranges in gearboxes. The list of automotive applications is continuously expanding.

Our engineers are researching materials and developing new, innovative products and designs. Our dry-tech product range currently encompasses products such as tribologically optimized plain bearings, gears, lead screw nuts and lead screws, spherical bearings, ball bearings, and much more.
