3EXTRUSION PROCESSESFor high-quality fi nished products

Gear pumps optimize the extrusion pro-cess of thermoplasts as they supply the required melt very precisely and effi cient-ly build up the tool pressure thus reliev-ing the extruder itself from building up the pressure. This enhances the perfor-mance of the production line, improves the quality of the fi nished product due to reduced melt temperatures, and increases the lifetime of the extruder. In addition, pressure pulsations and pressure peaks of the extruder are eliminated or at least smoothened as the gear pump dampens such pulsations and peaks.

Further benefi ts of the gear pump are that the chips produced during the cutting process can be recycled and that the pump supplies the melt very uniformly through the die, which in return ensures a con-stantly high quality level on the fi nal products side.

In terms of processing quality and optical characteristics, products are subject to high standards. Another important aspect in manufacturing and processing of plastic material therefore is fi ltration, with the fi lter discharging impurities from the liquid plastic melt. maag pump sys-tems supplies the devices necessary for fi ltration in numerous fi elds of plastic production and processing. Permanent development processes improve these fi ltration devices and thus contribute to our customers and end users satisfaction concerning quality.

6The compact, durable gear pumps made by maag pump systems meet highest require-ments for thermoplastic applications. Thanks to optimized fl ow channel geometry, short and quality-supportive dwell-times are feasi-ble even for temperature-sensitive products. The gear pumps are easy to handle and guar-anteee reliable and quick start-up and shut-down processes for processing extruders and compounding extruders.

High conveying stability and task-oriented confi guration in combination with a high level of reliability support production stability for repeatable processes. The maag gear pumps convey the medium in a low-pulsation way even when exposed to high differential pres-sures. Special materials and material process-

ing steps as well as innovative bearings, mainly made from highly wear-resistant tool steel, allow high revolutions with corresponding high throughput rates. The excellent degree of effi ciency is also due to the fl ow-optimized design of the fl ow channels. The modular design and three different series meet varying requirements: extrex GP is the allrounder, extrex HV features a 25% higher pumping volume, and extrex HP is capable of dealing with a differential pressure of up to 400 bar.

The trudex gear pumps have been especially designed for high-pres-sure applications. These high-pressure gear pumps ensure reliable sup-ply quantities at up to 700 bar. This guarantees highest possible prod-uct quality. Special, spur-toothed shafts and special sliding bearings ensure excellent effi ciency factors while the conveyed medium is stressed only to a very little extent.

Optional accessories such as cooling for shaft seals, melt pressure sen-sors, or temperature sensors complement this effi cient gear pump line.

The DV melt valves are based on the proven bolt design operating without any mechanical seals. Such melt valves are applied as diverter valves, safety valves, or start-up valves in plastics production and extrusion and compound-ing applications. The sturdy design and a reliable electric, liquid, or steam-driven heating system ensure leak-free and trouble-free operation for years, e.g. as start-up aid for underwater pelletizing processes or when start-up ma-terial has to be discharged in extrusion applications.

When set to production, the melt stream fl ows down the melt channel and reaches the next downstream sta-tion. In order to divert the melt to start-up, the bolt is activated hydraulically. This switching can be slow or quick, depending on the individual process control-related needs and is ensured through various hydraulic systems.

The expac system made by maag reduces negative im-pacts such as the pulsation of an extruder. Pulsations may lead to dimensional deviations of up to 5% on the fi nal product due to wear or added recycling material. The ex-pac system signifi cantly reduces such deviations and thus improves product quality. The quality of the material, and of the product later on, also depend on short dwell-times of the melt inside the pumps, screens, and mixing ele-ments. The speed of the entire process and resource-con-scious usage of energy defi ne process productivity.

expac systems are mainly intended to retrofi t already ex-isting systems but can also be integrated into new systems.

maag has business roots extending back more than 100 years. The foundations for todays maag pump systems AG were laid by Max Maag in the year 1910, beginning with gear manufacture. The business grew, and in 1928 the companys factory in Zurich shipped its fi rst gear pump. In the decades to follow, maag engineers developed ever more sophisticated and capable gear pumps. Today, these pro-cess pumps are in operation around the world, serving customers in the plastics, chemical, petrochemical and food pro-cessing industries. At the start of the new millennium, maag pump systems expand-ed its product range to include high-per-formance screen changers and large-area fi ltration units so that, since this time, it has been able to offer complete systems.

After more than six decades serving the plastics industry, it is hard to even imagine this market without pelletizing systems from Automatik Plastics Machinery. Originally founded in 1947 as Automatik Apparate- und Maschinenbau GmbH, the compa-ny began developing strand pelletizing systems from its earli-est days, bringing the fi rst automated strand pelletizer to the market in the 1960s. The 1970s saw a further burst of innova-tion, particularly the companys launch of the fi rst underwater strand pelletizer in the middle of that decade. In the late 1990s, Automatik went on to bring its unique drop pelletizing system for low-viscosity products to the market, fi lling yet another in-dustry need. The company completed its product portfolio in 2003 with the introduction of its SPHERO underwater pelletiz-ing technology. Since this time, Automatik has offered solu-tions covering a comprehensive range of pellet shapes, operat-ing throughputs and production requirements.

The paths of these two extraordinary companies have crossed many times over the years, as both have long been providers of complementary, superior quality systems and components to the plastics processing industry. With their merger in 2010, maag pump systems and Automatik Plastics Machinery were brought together under the umbrella of maag, offering com-plete and highly effi cient pro duction solutions from a single source. maag has been a part of Dover Corporation, a U.S. in-dustrial conglomerate, since 2012.
