Mobile telephones connect all people across the world

What started off in 1983 as a 800 gm Motorola device, sneeringly called `jingling bone`, has embarked on an unbelievable triumphal procession around the entire globe: the mobile telephone. Experts meanwhile estimate there to be 4 billion mobile phone users worldwide. The market is flooded with a multitude of mobile phone models, which can do a lot more than just phone. The Finnish giant in this sector, Nokia, is the largest producer of mobile telephones, followed by Samsung. Today`s handys weigh less than 80 gm, they take photos, record and play back videos, surf the Internet or are navigators for drivers and pedestrians who are unfamiliar with the surroundings.

Mobile phones are produced in an industrial mass production environment. Three-shift production operation places high demands on people and material. The often quoted maxim `time is money` demands robust, low maintenance machines, which operate smoothly, even at high cycle rates. If during screw assembly in a factory in the mobile telephone sector delays are caused by screw presenters, for instance as a result of jamming of the hardware in the feeding device, this jeopardises production targets and the profit margin is not achieved. Particularly when the demands of industrial series production are very high, an extremly robust design is required. Devices with marginal guide plates and tooling are unable to support the duty cycle of the operator over extended manufacturing periods.

Recently a `distress call` from a customer in India reached DEPRAG SCHULZ GMBH & CO.: `Please supply us with functioning screw presenters!` For a project of this type, DEPRAG, being an automation expert with Head Office in Amberg/Upper Palatinate, who are renowned for quality and competency in auto feed systems, proved to be the suitable partner. DEPRAG engineers went to work and within a short period of time they developed a robust, extremely low maintenance
