Apple Job Listing for Plastics Design Engineer Hints at Innovative Designs for Future Products
Identify, develop and launch new tooling and process capabilities in support of new Apple product developments. Areas of focus will be "non-traditional" Apple plastic processing such as thermoforming, foam molding, blow molding, etc., and their application to new Apple products. The successful candidate will have demonstrated history of bringing new process and tooling technologies through a full development cycle and launch into high volume production.Though Apple has focused heavily on aluminum for the iPad, the iPhone, and the MacBook line for the past few years, the Cupertino-based company has continued to prominently use plastics in such products as the Apple TV, the AirPort Extreme, keyboards, and other accessories.
Recent rumors have suggested that Apple is working on a low cost iPhone that will be constructed primarily of plastic. The iPhone is said to be a hybrid of the iPhone 5 and the iPod touch, with a plastic enclosure.
A new hire specializing in plastics is unlikely to be involved in the design of the low cost iPhone, given that it is rumored to be released later this year, but the open position does support reports that Apple is focusing on novel uses of plastics for upcoming products.
