Simon Moore to speak at WaiCAM 2010 Symposium

Wednesday, November 10th, 2010

This Friday (12th November) Puku CTO Simon Moore will be presenting at WaiCam 2010, a science symposium to be held at Waikato University.

The symposium is focused on titanium research, development and commercialisation and will be attended by a diverse set of academics and industry professionals. Simon’s topic explores how the use of helices can change physical properties of metal. In particular, how a helix form can increase elasticity of Titanium which presents opportunities for biomedical applications.

Puku’s Spring Bolt is a Star

Thursday, July 22nd, 2010

A research and development centre to capitalise on pioneering New Zealand titanium technology – including bendable bolts – has been opened in Tauranga.

The Applied Powder Metallurgy Centre will help companies develop and test revolutionary titanium products.

Titanium – the metal with the best strength-to-weight ratio – is used for aerospace, industrial, medical and automotive products.

Its uses include hip joints, metal plates for implants, surgical tools, cogs, nozzles, jet engine parts, sports equipment, filters and advanced coatings.

The bendable bolts are particularly effective when used with self-locking nuts.

The centre has been set up by the Titanium Industry Development Association with funding from Trade and Enterprise.

Tauranga firm Titanox Developments has come up with the process for turning titanium metal powder into solid objects.

Puku’s CEO Interviewed on National Radio in NZ

Here is a short radio interview with Dan McElrea – CEO of Puku Ltd

One of the nice things that keeps occurring is I rediscover notions I knew, and  strangely it is almost as if they are “new-to-me” again!

An example of rediscovery:

  1. In 2003, when developing the cam-operated mechanism we used in the Puku putter we decided to mirror finish a surface for a better interference fit
  2. In 2009 – yesterday, in testing a sample of the new Puku vDove technology for wear issues, I found the more it wore the better it became – which surprised me – until I realized the wear was creating a mirror like finish!


Nice patent progress today …

Great news to day – a very good PCT examination report for one of our patents in process  – This technology can take pipe connection to a new level of safety …. and uses some aspects you see in the Chinese Finger Trap and self locks pipe elements together in a vibration/ shock/thermally resistant manner.
