Elmet Elastomere Produktions- und Dienstleistungs GmbH, Oftering, Austria, offers a high-precision, automatically controlled multicomponent dosing system with a high-resolution flow meter. Integrated as a closed-loop control instrument into the colorant and additive feeding system, it determines the dispensed volume with a resolution of 640,000 increments per liter.

Bolder automation GmbH in Limburg, Germany, will showcase an alternative solution to plastics blend feeding. For this purpose they developed a PLC assembly unit to whom a blending unit including all valves, scales, blender and all remaining sensors is linked, and configured. Based on Simatic S7-1500 control technology, a batch metering unit with PLC units was mounted to the plant, which can be linked to any desired blending equipment. To provide for precise and fast weight measurement, Siwarex assembly units are employed, while communication is done via Profinet.

Universal Control for Gravimetric Blending 

The new WXB Weigh Extrusion Blender from Maguire Products, Inc., Aston/Pennsylvania (USA), incorporates a gain-in-weight (GIW) weigh bin and a loss-in-weight (LIW) mix chamber in one machine with a Maguire 4088 controller. According to the manufacturer, the tight tolerance achieved by the blender (within +/- 0.1%) is a key to conserving raw material.

motan-colortronic GmbH of Friedrichsdorf, Germany, will introduce a variety of dosing and mixing units as well as feeders to the market. The Metro product series includes solutions for material conveying as well as hopper feeding that has been expanded to include the Metro SG HOS and HES in what is called a “simple solutions” line. Up to eight funnel loaders can be controlled by the compact control unit Metronet SG. The Moisture Minder sensor will also be presented that can display a trend graph of the residual moisture in dried granules.

More Efficient due to Redesigning 

Processors have a variety of systems available for drying pellet stock. The dryers are often integrated into the material supply line. This article gives an overview of this by no means dry subject.

An Important Process Stage for Manufacturing High-quality Products: Optimum Drying of Pellet Stock 

Infrared and vacuum drying are additional technologies now finding application in plastics processing to reduce residence times and/or energy consumption. However, great efforts have also been made in recent years to improve the efficiency of conventional dehumidified-air drying. 

Material Supply: More Efficient Drying 

Nowadays, use is generally made of electrical heating elements to heat machines and equipment in the field of plastics processing. More recently, natural gas-heated units have come onto the market as a viable alternative. In this article, the author explains their advantages and presents some of the latest developments.

Heating: Natural Gas in Plastics Processing 

At the Weert/Netherlands site, Klöckner Pentaplast recently brought a new extrusion line on stream. Its ancillary material compounding line is required to meet severe demands. 

Material Compounding for Film Extrusion: Drying, Conveying and Dosing of PET 

The handling of plastics pellet stock is extremely important, particularly in the extrusion business. Firstly the material must be fed with the correct composition (following the formulation). Secondly material tearing, for example in film extrusion, can involve a very long and expensive restarting process. 

Product Quality also Depends on Conveying, Metering and Drying Systems: Plastics Handling in Extrusion 

The production site of FTE automotive systems GmbH in Ebern-Fischbach, which opened at the end of 1999, will ultimately accommodate 59 injection moulding machines, on which automotive supply parts for brake and coupling hydraulic systems will be injection moulded.

Drying, Conveying and Mixing System for the Manufacture of Plastics Automotive Parts: Centralized Supply for 59 Injection Moulding Machines 

Mann+Hummel ProTec GmbH has completed the relocation of its facilities in Ludwigsburg, Weiterstadt and Königswinter to a new site in Bensheim ahead of schedule. A green-field factory was literally erected and designed according to the Kanban principle. Kunststoffe’s chief editor Gerhard Gotzmann paid a visit to the new site and talked to Norbert Strohbeck, production manager, and Michael Zlotos, CEO, about the advantages of the centralisation, the situation in the sector and current technical trends. 

Materials Handling: Centralisation Complete 

The pre-stage of processing is crucial for the economical production of an article in a specified quality. As determining factors, plant availability, good drying results, operating safety, as well as high functional variety, together with easy operability of the control unit, must be regarded. 

Fully Automatic Conveying and Drying: From the Material Store to the Injection Moulding Machine 

In the framework of the company’s global alignment in the Nineties, Mann+Hummel was faced with the question of how to best gain a foothold on the American market. The decision-makers felt that the answer lay in the purchase of an American company, and hence Universal Dynamics Inc. was acquired in 1995, which, since then, has strategically divided up the worldwide market for industrial plants and components with Mann+Hummel ProTec GmbH. 

Strategic Cooperation: Differentiated Market Working for Customer Proximity 

Material Handling Effectively Mastered by Smart Technology 

The demands placed on material handling in recent years continue unchanged. The systems should be both flexible and precise, and characterized by automation and efficiency. These requirements apply over the entire conveying distance, starting with the drying and cleaning of the material and ending with the dosing and blending of it. The companies engaged in this field keep on finding new ways of improving their systems, above all in detail.
