The evaluation of “how to develop the preventive maintenance of plasticization systems using trend data” should correspond to the three sets of evidence on the state of particles, the behaviour of the molten and the quality of the finished product. The key mechanisms of this theme are: long-term trends in measuring time, twisting, mating, pressure and energy consumption can signal before severe wear and tear. Stable plasticization of the refuelling, measurement, DOE, trend monitoring and material database, rather than single modem experience. Therefore, the name of the material and the recommended setting can only be used as a starting point, and the actual judgement is to return to the plate number, water, filling and assistor, the single total quantity, cycle, screw structure and product requirements to confirm whether the temperature, cut and stay of the material in the equipment is safe.

In the phase of trial modelling or mass import, an input list should be established around “How to develop plasticization systems for trend data” including feedstock suppliers and batches, technical data tables, drying conditions, colour mother and retrofit ratios, equipment and screw specifications, product and flow weight, mold temperature and existing defects. If cross-platform reproduction is required, the screw surface velocity, unit gel volume and time of stay shall be converted and the speed and temperature shall not be applied directly. The main risk of this theme is that the absence of baselines or frequent changes in parameters would render trends uncomparable and delay maintenance. Parameters must be recorded in a specific pattern to distinguish material from equipment from operational changes.

Control methods should not begin with blindly increasing temperature or pressure, but should be based on "substance state - feed drying" The sequence of screw plasticization - nozzles and fluids - product results. Where the defects can be temporarily pressured by extreme temperatures or back pressure, it is more important to confirm the existence of structural, water-bearing, pollution or gaping problems. The site adjusts only one main variable at a time, while observing the actual melting temperature, measuring time, screw twists, mats, injection pressure, product weight, colour, scent and critical dimensions. If production can only be sustained by extreme parameters, the use of a switch to cover the material or hardware boundary should be discontinued.

The validation of “how to develop a plasticization system for preventive maintenance using trend data” suggests a replicable approach: locking in the baseline process, tracking trends by production and combining size and wear and tear measurement. In case of over-limits, the relevant batches and products should be isolated before re-entry, downgrade or stoppage is decided on the basis of retention and trend data. The technical agreement between the supplier and the plant shall state the material, the sampling method, the detection project, the permitted scope and the change notification requirements. The plasticization programme can only be considered to have long-term quantitative value if the product ' s probabilities, performance, cyclicality, energy consumption and maintenance costs are met in a continuous production process.
