Nissan uses unique technology for forming parts without a press

Many classic cars enjoy great support from the secondary market, but this is not always the case.

The search for spare parts for rare or less popular models is complicated, sometimes completely impossible. Nissan understands this, and therefore has developed a patented technique known as double-sided molding. The company claims that the new method is quite flexible, offers short lead times and minimal upfront costs. This means that it can be “commercially profitable to produce and sell a large amount of after-sales service and spare parts in small volumes for cars that Nissan no longer produces.”

For two-sided molding without a press, two synchronized robots are used, on both sides of the steel sheet, which gradually form the metal with a diamond coated pin. At first glance, this is quite simple, but the real difficulty lies in programming robots for synchronous operation. Nissan says they were able to solve this problem by developing advanced programs that can control both robots with “a high degree of accuracy, allowing them to form detailed convex and concave shapes.”

Company representatives did not go into details, but noted that existing methods are primarily based on one-sided molding, which limits the complexity of the forms that can be created. Nissan also said that the use of mirrored diamond cutting tools reduces friction, and this eliminates the need for lubrication. This has several advantages, including lower costs, improved surface quality stability and less environmental impact.

There is no evidence of when Nissan might begin offering parts manufactured using double-sided stamping without a press, but the company has been increasing its commitment to classic cars over the past few years. In particular, the Nismo Heritage Parts project was launched, which offers a range of spare parts for the R32, R33 and R34 GT-R.
