3. 3D PLANNING OF THE PLANT 15
3D PLANNING OF THE PLANT Links site planning with component construction Enables the integration of a larger group of people into planning 3D scanners allow the recording of the building contours Complex space situations can be analyzed excellently Reduces construction site expenses by means of collision tests Another "view" of integrated engineering Integrated engineering is very helpful for the validation steps planning and documentation 16
INTEGRATED ENGINEERING WITH PDMS From the database-based planning tool (Comos PT) to 3D planning until now: Integriertes Engineering: Access - Claims - Std- kont. - etc. Word - Specs - Anfragen - Doku - etc. UNIPPS - Bestellung - Budget - etc. Excel - Data Sheets - Listen - etc. TRICAD - 3D Planung - Isometrie - P& ID s - etc. Power Point - Doku. - Infos - etc. And.

4. BATCH TRACING Laws and regulations to be considered EU Regulation 178/2002 (Focus on the Food and Feed Industry) or GMP + Consumer protection, proof of origin, labeling requirements Risk minimization, recall of defective products Quality control through the supply chain Asset validation Optimization potential Determination of liability 21
PRODUCT FLOW ALONG THE SUPPLY CHAIN (supply chain) Rohstoffe Händler, Veredler Endverarbeiter Traceability makes it possible to reconstruct the entire supply chain as well as parts of the supply chain. 22
REQUIREMENTS Unique identification of raw materials Documentation of critical processing steps, formulations, process parameters and quality control Clear identification of your own products and allocation of production lots Proper treatment of batching, overlapping, cleaning and carryover Traceable and accurate detection, recording and archiving of all necessary data, compressing to information 23
EQUIPMENT REQUIREMENTS No cross contamination 24
RETRACEABILITY Summary No mixing during storage, discharge and dosing Avoid cross-contamination and carryover No mixing of identical raw materials of different batches - clear assignment to batch number Careful cleaning of the containers Avoidance of data acquisition errors, control of manual operations Control concept and data compaction to information, communication with ERP systems Batch tracking does not end at the factory limit!! 25

5. SOFT PVC - P COMPOUNDING Standard soft PVC - homogeneous absorption of plasticizer - dry Dryblend - variable raw material selection - high throughput up to 9,5 batches/hr - with up to 85 % filling Important: Very fast plasticizer absorption Medical soft PVC - absolutely complete homogeneous plasticizer absorption - free-flowing Dryblend with no gelled agglomerates, - without any influence to the compounding parameters - nearly free of any pits - constant valuable parameter Important: Shear near the bottom 27
PROCESSING STEPS PVC-P FORMULATION Feeding of all components into the mixer. Heating of the mixture by friction up to approx. 65-95 C with a tip speed of up to 40 m/sec. Validation process: Reduction of tip speed to 12-28 m/sec. Start to adding plasticizer, depending on the temperature increase after final liquid adding increase of speed up to 40 m/s After reaching the final temperature of 95 165 C: Reduction of tip speed to 20 m/sec. Discharging into intermediate hopper or cooler mixer. If cooling is desired, cooling down to 50 75 C. Documentation and recording of each processing step With - Times - Temperatures - Velocities 28

PVC-P PLANT FLEXIBLE PVC PLANT FOR MEDICAL HOSES WITH COOLING MIXER FLEXIBLE PVC PLANT FOR MEDICAL HOSES WITHOUT COOLING MIXER 33
PVC-P PLANT without any mixer for medical application Formulation: Bulk density: Throughput: medical hoses 0,60 kg/l 1,1 t/hr Inline compounding: All steps inside the Extruder: - Mixing, heating - difusion of plastciser - Melting - pressure buildup - profiling 34
PROCESS TECHNOLOGY Patented conical shaped mixing elements (EP 1 829 660) with self-cleaning effect for soft and gentle melting of polymer and homogenising of fillers and/or fibers 35
PROCESS TECHNOLOGY screws HENSCHEL Compounder conventional Compounder Low shearing and less mechanical forces Homogenous thermal distribution without temperature peaks Reduced energy demand due to low torque Less wearing due to bigger gap between screw elements 36
COMPOUNDING WITHOUT MIXER process and production competent system for continuous preparation of PVC-P With: Consequent energy reduction Flexibility Reduction of building complexity 37
COMPOUNDING WITHOUT MIXER 1. Extreme energy savings (55%) (future energy cost, background energy transition) 2. Simple and clear production 3. Low installation expense 4. No segregation because intermediate storage is omitted 5. No cross-contamination and thus less damage and less scrap 6. Saving of up to 2/3 of the building height is possible 7. Strongly simplified standard buildings 8. Low cleaning expense for formulation or colour changes 9. High flexibility in recipe changes 10. Easier operation by means of less complexity and easier overall controls 38
