1 Vacuum and Pressure Solutions for the Plastics Industry The nnovation leader

2 Why Elmo Rietschle? Nowadays industrial customers face a wide choice of vacuum pumps and compressors. Many features of the products offered are similar or at least that is the claim. Product quality goes from modest to high as do prices. Needless to say that the match is not always obvious. So what are the key characteristics that you should look for in a partner for your vacuum and pressure requirements in the plastics industry? Here is what Elmo Rietschle has to offer. Not to forget that more than half a million Elmo Rietschle machines are in use in the plastics industry. Widest Choice of Technologies You can decide which technology works best for you based on your specifications and not on a restricted product offering from other suppliers. You define your requirements and preferences and then you have the choice between eight product technologies and sometimes even combine them. Energy Efficient Solutions This translates into lower life cycle costs for you with less money to spend on energy bills. Using advanced smart features such as our variable speed drive you have maximum control over your machine park. Going green gets easier! Life Cycle Champions We can prove to you that using our great selection of dry running technologies means spending less money for service, lubrication and down time. And the ROI is much shorter than you d ever expect. Life Cycle Champion 2

4 Vacuum and Pressure for Applications in the Plastics Industry F-Series Radial G-Series Side Channel L-Series Liquid Ring V-Series Rotary Vane C-Series Claw S-Series Screw Calibration The thermoplastic molten tube leaving the machine is cooled and, if necessary, calibrated under press quenching with the help of vacuum pumps. Plastic welding The hot air that is needed for welding is heated to between 200 to 300 C using heating cartridges and is accelerated to high velocity using a blower. EPS foaming Using a side channel blower, pre-expanded polystyrene balls are blown into a mold where steam is then applied. At final polymerization, the balls are cured into the molded component. To ensure that the molded components do not lose their shape when removed from the mold, they must be cooled with water. With vacuum pumps the water vaporizes in a flash. Extruder degasification Vacuum pumps remove air pockets and moisture from the melted plastic mass. They extract all of the low-molecule substances, ensuring optimal quality: smooth surfaces, greater strength, better insulation capabilities and a lower outgassing rate. Pneumatic conveying Plastic molding presses / extruders are automatically loaded with the help of our blowers or vacuum pumps. For this purpose, a vacuum is produced in the material container. The granulate is conveyed through the air in the tube. 4

5 F-Series Radial G-Series Side Channel L-Series Liquid Ring V-Series Rotary Vane C-Series Claw S-Series Screw Contact-free plastic film redirection Continuous plastic sheets and films are redirected contactfree with air that is applied on turning bars. Drying granulate Many synthetic materials are hygroscopic and their moisture content must be greatly reduced before they can be processed. This is achieved in so-called granulate dryers. Before the air is blown with a side channel compressor into the hopper containing the granulate, it is passed through dry ing containers containing a desiccant. This desiccant is regenerated in a separate process using a side channel compressor. Cooling & drying extruder products The hot plastic material that is discharged from the extruder must be cooled down quickly. This is done using blast air or by cooling the material in a water bath, followed by a drying process. Deaeration of rubber components / evacuation In production stations that manufacture rubber components, vacuum is used for evacuating air from the die cast mold thereby preventing the formation of air pockets and accelerating the rubber mass. Gluing plastic parts In the production of glued composite materials, panels are secured to each other with an adhesive and pressed into a sheet. The sheet sack is evacuated for this purpose, so that the atmospheric pressure can produce the required compression. 5
