1 EXTRUDER TECHNOLOGY

2 Extruder Technology Top class Wearing Parts It s the art of right handling and conveying of different masses. Material is being processed to be finally formed or dressed and modified for further treatment. All these ways of conditioning have one thing in common: whereever masses and machine come together is where the most wearing occurs. Since 1876, C.A.PICARD use all their knowledge about metals. For decades, we have been well-established as one of the world s leading manufacturers of wearing parts for specialised industries. Our highly-skilled employees and state-of-the-art machining procedures stand for precise and highly wear-resistant parts and equipment. Precision means OEM-Standard or beyond Spare and wearing parts for: Twin screw extruders Screw presses Extruders Mixers Kneading machines Components: Screw elements Kneaders Screw shafts Barrels Cylinders Injection rails Baffles Skill means synergy of experience, know-how and development.

4 We know your requirements Every market follows its own rules. High pressures, high temperatures, physical abrasion and corrosive attacks must be compensated and requirements for mixing, for special treatments or hygiene and food standards need to be observed. Thus, we are perfectly acquainted with various different application areas, we share your knowledge about product processing and design the ideal wear parts for your extruding requirements. Our materials and technologies are designed to extend life-time and to improve quality produced. Branches and Industries: Plastics Industry Food Powder Coating Chemistry Petrochemistry Pharmacy Pet food Industrial Ceramics

5 Users of all well-known extruders are convinced of our quality and experience. This is the living proof of C.A.PICARD s core components in your production line.

6 Segments In many areas, extruder production nowadays is modular. Due to this, it is possible to adjust the screw configuration ideally and to replace renewable segments at reasonable price. The screw segments are mounted on a supporting shaft and perform different tasks during the manufacturing process. It is our goal to improve performance, e. g. increase of retraction and conveyance or cutback of top-level temperature or shear stress. More than elements can be supplied ex stock. Building Types: Conveying elements Reverse conveying elements Kneading blocks and discs Mixing elements Transition elements Undercut elements Side feeder screws Single, double, triple lobe Diameter 12 to 350 mm The mentioned categories are based upon C.A.PICARD s experienced data, material analysis and information provided by customers.

7 Shafts They transfer the torque of drive to the screw segments and thus into the whole area of process. Apart from offering the maximum torque drive, it is our aim to achieve the maximum mechanical durability. Using modern material engineering, we achieve resistance that enables you to take your twin screw extruder to the limits. Building types: One-piece or multi-parts Diameter 10 to 180 mm Length 500 to 6000 mm Optional with or without internal cooling Material Portfolio Code Type Use DF Hot-forming Steel High torque DT Heat treated Steel Ball screws EG Hardened stainless Steel Corrosion resistance D5 Special high-alloy Steel Laboratory D4 Heat treated Steel Laboratory Screw Dismantling Service You may have to make an effort to strip the segments off the shaft after production time. Residuals of products might stick between the segment and shaft and have solidified. It may be necessary to use high force to remove the elements off the shaft. For this task, we offer our screw dismantling service. As soon as your screw shaft arrives in our plant, we note the configuration, strip off the elements hydraulically, clean them and check their wear condition. Depending on your requirements, we re-assemble the screws with necessary replacement parts, either with identical or modified configuration.

8 Barrels and Liners As the barrel and the cylinder must resist extreme friction and have different other tasks to perform in the process, they are particularly high-value parts of a twin screw extruder. They can either be used for feeding or degassing. Quite often, the barrel is equipped with a temperature control system. Sometimes the corrosive and abrasive effects on this extremely valuable parts make it necessary to equip the barrel with a liner which can be replaced as soon as the wearing limits are exceeded. Thus it is possible to replace only the liner and the valuable external body can be kept in use. Building Types: Feed barrels Closed barrels Side-feed barrels Venting barrels Combi barrels bore system for temperature control possible with or without liners with or without thermocoupling bores with or without injection bores Wear liners Degassing insert Plugs Degassing dome Barrel figure 8-bore Diameter 12 to 350 mm The mentioned categories are based upon C.A.PICARD s experienced data, material analysis and information provided by customers.

9 Maintenance and Repair Barrels are complex and expensive parts. Once they are worn, they don t necessarily have to be scrapped and in many cases it is an extremely cost-effective solution to get them repaired. In case you have a lined barrel, we ll check the barrel and refurbish it if necessary. After removing the old liner and fitting the new one, the barrel is technically as good as new and ready for use. If the barrel is not equipped with a liner, we ll check if we can fit a liner which is quite often possible for various types of barrels. In future, it will be possible to simply exchange the liner. Save money and conserve resources by repairing your barrels Wear Measurement Early detection of wear ensures your productivity. The C.A.PICARD barrel measuring system checks your barrel s condition directly at your extruder. The expenditure of time is reduced to a minimum while there is a maximum benefit since the barrels don t need to be removed. Our maintenance makes sure your machines run smoothly, possible deviations are detected early, you can order spare parts in time and thus make repairs easy to schedule and to calculate. The measures are taken at room temperature. For preparation all you need to do is to strip the screw shafts and to clean the barrels. At a fixed price we offer: measurement and analysis via computer interface by our C.A.PICARD service with measuring system including documentation of the results. We also offer measuring your screw elements wearing. For following twin screw extruders (measuring range of sensors 39,5 to 118,5 mm diameter) Examples of use Coperion ZSK 40 to ZSK 92 Leistritz ZSE 40 to ZSE 110 Berstorff ZE 40 to ZE 90

10 Twin shaft extruders for powder coating The main reasons for some industries diversifying from liquid to powder coating are profitability and environmental aspects. The powder coating method is currently being used in the automotive industry, metal coating, production of domestic appliances, for furniture and many other branches of industry. As a specialist in processing of extrusion the C.A.Picard Extrusion Technology S.r.l. in Cusago near Milan/Italy is our Group s centre of excellence for development, delivery and service of powder coating plants. Taking advantage of their long-time experience which is well-known in the trade, the Development and Sales Team designs production- and laboratory extruders for world-wide use which meet all requirements to homogeneous and accurately repeatable lacquer quality. The melt is being solidified and rolled out by attached cooling belts exactly according to the customer s requirements concerning logistic and cooling efficiency.
