Oerlikon Barmag will be exhibiting at the K 2016 trade fair for plastics industry that will take place from 19-26 October in Düsseldorf, informing the audience about its new developments in the fields of extrusion equipment and pump engineering.

With its Oerlikon Barmag and Oerlikon Neumag brands, Oerlikon Manmade Fibers segment is the market leader for manmade fibre filament spinning systems, texturing machines, BCF systems, staple fibre systems and artificial turf systems. As a service provider, it offers engineering solutions for the entire textile value added chain.

Tape yarns for different applications

In Hall 16, where the company will discuss extrusion equipment, the main focus will be on solutions for tape production. The new developments from the Chemnitz-based think tank focus mainly on the EvoTape machine combined with the automatic tape yarn winder WinTape and – a trade fair premiere – an automatic baler yarn winder.

Presented for the first time at the K three years ago, the combination of tape system and winder is said to offer significant profitability increases of as much as 50% – not only for carpet backing and geotextiles processes, but now also for baler yarn processes – compared to standard machines available on the market.

EvoTape 800 and WinTape mini also aim to offer an economical solution for sack and big bag fabric. WinTape mini was developed specifically for the production of tape yearns which are round-woven during further processing.

High-speed extrusion pump for greater throughput rates

In Hall 10, dedicated to pump engineering, Oerlikon Barmag's pump specialists will be presenting the new high-speed extrusion pump, which is said to achieve greater throughput rates with a lower investment volume. With the increased speeds it is possible to achieve a much greater throughput setting range reducing pulsation at the same time, the company explains. Furthermore, the reduced friction surfaces are said to make for a smaller temperature increase in the melt and therefore for more efficient and energy-saving production.

The improved process characteristics with higher throughput rates come on top of other benefits offered by the Oerlikon Barmag extruder pumps. According to the manufacturer, these include a marked volumetric efficiency, a special compressive strength, high leak tightness and long service life.

The combination of these advantages are designed to enable to end user to achieve double the throughput rates with the same pump size, but a substantially smaller melt temperature increase.

Concentrated flexibility

The pumps of the GM series have been developed specifically for use under difficult conditions. They aim to provide high-precision metering even in the most demanding situations, for example, when pumping low-viscosity media under high pressure. The latest member of this sturdy pump family is the GM ‘E’ type pump.

With a greater setting range in the ratio of 1:40 and the resulting throughputs of 0.5 ml/min to 40 l/min, the ‘E’-type pump covers a substantially wider production window. For the manufacturers of various components of polyurethane systems, such as foam blocks to make mattresses, this can mean that the number of pumps needed can be cut by as much as 50%. According to the individual pump type, the flexibility in production is also increased.

The compact design and low weight of the pump keep the load on the machine as low as possible, which has a positive impact on service life. Assembly and disassembly are also made simpler thanks to the use of centering dowels, which is said to significantly cut the manpower needed for servicing.
