The control of “how to sort out the colour difference from the material and plasticization chain” is to be stabilized, first of all by distinguishing between the intrinsic properties of the material, the state of the material and the thermomechanical effects of the equipment. The key mechanisms for this theme are that colour differentials may come from batches, water-bearing, chromosomal metrology, dispersion, thermal history and cleaning machine residues. 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 “how to sort out materials and plasticization links in the retrofit colour difference”, including feedstock suppliers and batches, technical data tables, dry conditions, colour mothers and retrofit ratios, equipment and screw specifications, product and flow weight, model temperature and existing defects. The detection sites should cover dryer exports, aircraft-side pyrotechnics, air-launched molten products and products, so as to avoid drawing conclusions only at one point. The main risk of this theme is that blindly increasing colored mothers can change formulations and mask temperature or mixing problems. 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. Any new parameters should indicate the application of card numbers, filling ratios, respiration ratios and environmental conditions, avoiding misuse of materials with similar names but with different behaviour. 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.

Repetitive methods are recommended for the validation of “how to sort out the material and plasticization chain” with a standard light source, colour ranger, description, molten temperature and clean-up record. The data should be validated by programme, quality and equipment personnel to avoid miscalculation of material, mould and mechanical problems. 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.
