Piovan also provides software for process management and quality traceability of production batches that easily integrates with the ERP used. Management of material batches, centralised transport with automatic sorting units, self-adaptive dehumidification based on actual hourly production, accurate dosing even at low quantities and efficient and precise mould temperature control guarantee the maximum quality of the finished product. It designs complex turnkey systems where the numerous materials and high standards require ever greater process flexibility. Injection moulding is a key process for the production of most technical components used in the construction, electrical, furniture, household appliance and toy industries, such as computer components and keyboards, mobile phone housings and household appliance parts. These industries in particular demand the highest quality, process stability and reproducibility.įor more than 40 years the Piovan Group has been manufacturing industrial automation systems for the technical moulding of high quality plastic articles. Read the complete article published on ComPETence.Quality, process stability and reproducibility production of technical articles The dryer continually adapts its operation even more effectively in order to keep it within a working range suitable for the type of production, with variations not exceeding ± 2 bar throughout the cycle. With the aid of a signal transducer, the injection pressure is continually measured at the extruder and sent to the Genesys dryer. DP and DPM are characterised by dew point lower than -50 ☌ and process air temperature up to 200 ☌ (HT version). With AIPC, the IMM itself supplies the data necessary for process management, ensuring that the degree of drying is really suitable for the type of preform to be produced. Now, Piovan has successfully researched and developed an innovative system for minimising them: AIPC Technology. In everything we do, we strive to improve environments for a. The attributes that will empower us to achieve our goals include customer focus, accountability, collaboration, innovation, and agility. it allows reductions of 35% to 55% in electricity consumption, independently stabilises the air flow in the drying hopper and recovers energy for sieve regeneration, creating additional savings compared to the conventional systems currently used for PET processing.Īlthough precise, injection pressure monitoring is one-way and takes place on a feedback basis in addition, the graph of this essential parameter shows significant variations. Dwyer delivers high value environmental solutions combined with the best experience in the industry for our customers and partners. it automatically, continually manages the quantity of air to be introduced into the production process Equipped with a state-of-the-art control, Genesys is a "self-adaptive" system: Prior to the introduction of automatic pressure control, Genesys dryer’s performance was optimized using the AECS algorithm, based on measurement of the weight loss of the dried material. Keeping it constant ensures that the preforms produced always have the desired properties and physical characteristics. Injection pressure is a fundamental process parameter, because it is directly dependent on the amount of water left in the PET after the drying process. On the contrary, the pressure fluctuates continually, causing possible variations in the characteristics of the PET products. In a conventional PET preform production system, the resin drying phase is not connected to injection and preform production: therefore, the pressure does not always fall within a predetermined range of values which could ensure a constant product quality throughout the cycle. Process control, stable product characteristics and improved energy efficiency: Piovan's long-standing aims have now also been achieved in PET treatment thanks to its Automatic Injection Pressure Control (AIPC) Technology.Īutomatic control of injection pressure: this is the meaning of AIPC, the new Piovan patent-pending technology which enables the injection moulding machine to "guide" the Genesys drying system so that it operates with a constant injection pressure around a customer-defined set point.
