DC Generators Pin Down Permanent Fixing

Increased demand for high voltage document pinning has resulted in the development of a number of different high-voltage DC generators for the UK stationery and labelling markets.

Increased demand for high voltage document pinning has resulted in the development of a number of different high-voltage DC generators for the UK stationery and labelling markets.

The generators have all been specially designed by manufacturer Simco for the European market and now incorporate a number of advanced features allowing them to appeal to an even wider audience.

Typical applications include the pinning of paper, card plastics and films along with labels prior to permanently fixing.

Exclusively UK distributed by Advanced Dynamics, the company is introducing four new models in to the market.

The most important of these is the ECM, (European Chargemaster) a bipolar application machine.

Specifically designed to meet the needs of the web market, the unit comprises two power supplies each producing a positive and negative charge at different output polarities.

When connected to charging bars, they can make webs cling together electro-statically, without any physical contact.

Complementary to the bipolar model is the ECM-30, a high voltage model with an adjustable output of between 0 - 30kV at a maximum current of 5mA.

For very demanding applications, Advanced Dynamics recommends the ECM-60, a high voltage unit capable of producing up to 60kV at a maximum current of 2.5mA.

It is especially suitable for charging materials from a large distance, which often require much higher voltage.

For less demanding applications, Advanced Dynamics recommends the ECM Lite, a compact unit, capable of producing up to 0kV.

A built-in warning light advises of overload and this model is ideal for use where space is limited.

All models have been completely redesigned and have digital displays, membrane switches and optional remote control management.

Other features include a key switch preventing unauthorized adjustment and reduced case size.

The units work by generating high voltage at almost negligible current; the voltage is supplied through a choice of different charging bars that output a steady stream of ions to charge the materials for pinning.

The charging adheres the different materials to each other electrostatically, prior to formally gluing or joining.

A choice of electrodes is offered by Advanced Dynamics, include the Simco HDC - HDR, a rugged charging bar, built especially for more demanding industrial applications.

Also available is the pinner Arc-Resistant charging bar, which is fibre-reinforced making it suitable for temperatures up to 900C.

Advnaced Dynamics' director, Mike Essler said the introduction of new DC high-voltage generators is expected to create a great deal of interest.

"The new Chargemasters have been introduced following a big increase in the need for pinning.

The biggest demand is from in-mould labelling, thanks to benefits that pinning can provide.

They include being environmentally friendly and no product damage, thereby creating a win-win situation for all involved," he added.
