“What is usually caused by material stratification and stripping” appears to be a material problem that actually changes the performance of feed, melting, metrology, injection and product at the same time. The key mechanisms of this theme are that layers are often associated with incompatible resins, chromosomal carriers, pollution, demodelants or overcuts. Appearance defects are often caused by a combination of moisture, gas, materials, plasticization, moulds and equipment, and must be distinguished by evidence. 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.

At the test-model or volume-import stage, an input list should be established around “what is usually caused by material layering and stripping”, including feedstock suppliers and batches, technical data tables, drying conditions, colour mother and respirator ratios, equipment and screw specifications, product and fluid weights, mold temperature and existing defects. Process validation is best conducted through four further phases of start-up, heat-balancing, continuous production and short-duration, and to observe whether the window remains effective. The main risk of this theme is that the only increase in melting temperatures may increase incompatibility separation and reduce interface intensity. 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. If the process has to be in the vicinity of the equipment ceiling, the screw structure, the adhesive capacity, the heating capacity and the driving residual need to be reassessed. 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.

It is suggested that a repertoireable method should be used to verify “what is usually caused by tectonics and stripping of materials”: Check the material list for cross-section, infrared, surface energy, impact and clearance. The acceptance should not be limited to “specifically satisfactory”, but should preserve the rules of location, instrument, sample, upper and lower limits and unusual disposal. 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.
