Motor Cars and Medical Devices

As we highlighted eighteen months ago, the manufacture of motor cars has been one of South Africa’s great success stories over the past 25 years. Half of the 600,000 vehicles produced each year are exported, and for anyone living in the UK, Australia or Japan who owns a right-hand drive 3 series BMW  it will have been built in Pretoria. With the Western Cape province aspiring to become a leader in the development and export of medical devices, what can we learn from the automotive industry?

There’s an engineer in the USA who has a unique perspective: John Sapiente is the president and CEO of two companies, one a medical device manufacturer called Trident  and the other a supplier of automotive safety components called Elgin Die Mold. He believes that medical device manufacturers in 2015 are facing the same challenges that the Big Three – General Motors, Ford and Chrysler – faced in the early 1990s when foreign competitors introduced cars that were higher quality, more fuel-efficient and cost less. The American car manufacturers initially removed features to make their vehicles price competitive but that tactic failed dismally.

They then changed their mindset and embraced two concepts that had been used by the Japanese company Toyotakaizen, meaning “continuous improvement”; and muda, which translates as “eliminating waste”. Sapiente is convinced these two strategies should be adopted by medical device companies and makes a compelling argument for outsourcing: “For years, device manufacturers didn’t want to outsource production because they didn’t trust suppliers with quality. Now they’re looking for partners who not only understand quality but can also bring about cost reduction. Automakers have been doing that for years.”

At CapeRay we have adopted an outsourcing model for manufacturing many of the components incorporated in Aceso, our dual-modality imaging system. The final assembly and testing takes place in our Cape Town factory and, interestingly, some of our outsourcing partners also manufacture components for the automotive industry.

However, outsourcing is not the only strategy – one way we can save both time and development costs is by the use of an in-house 3D printer. Jono Makepeace (above right), an engineering intern who has worked for us for the past year, has recently designed and printed a four-piece plastic mould that he will use to fabricate a polyurethane gland to accommodate the cables of our custom ultrasound transducer (see left). He’s learning to embrace kaizen and muda !
