The Problem

An electric power equipment supplies manufacturer in the Kyushu district aimed to develop an anti-vibration nut to improve the safety of joints affected by vibration loosening of nuts and bolts. Initial designs and tests were carried out by a local spring maker, but they were unable to produce an effective product in the required commercial quantities. The company’s technical director approached Advanex on the web for cooperation on the proposed product.

The Solution

It took around 5 years to complete the product’s development from initial inquiry to it being a highly successful product in various industries. Advanex was able to provide a solution through:

  • Advanced manufacturing equipment and technology
  • Superior craftsmanship
  • Strict quality control

The only requirement the customer had for the product was to create a unique nut that used spring force to prevent it from ever loosening from a bolt through vibration. Even if just one bolt was to come loose it could be the cause of a serious accident.

In order to demonstrate the product it was subjected to strict severe acceleration tests applied to it using the customer’s own vibration testing machine, which was the only one of it’s kind in Japan.

If a successful product could be mass produced there would be a huge commercial advantage to be had by the customer as the leading national supplier to a large market.

Advanex were able to create an ideal solution to this complex problem. The combined sense of achievement felt between Advanex and the customer cannot be expressed in words. The customer dreamed of evolving from a local brand into a national leader and this has been achieved. They continue to expand into markets overseas.
