In material selection and in-situ modems, “how polymer molecules affect melting strength and mobility” cannot depend solely on the supplier's temperature table, but also on the actual product validation. The key mechanism for this theme is that the increase in molecular volumes usually increases the strength, resilience and viscosity of the molten body, with a concomitant increase in the plastered pressure and the plasticized load. The material structure, thermal performance and flow base determine the path to plasticization and cannot simply reproduce temperature and velocity by trade name. 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.

During the trial simulation or volume import phase, an input list should be established around “how polymer molecules affect the strength and mobility of the molten body”, including feedstock suppliers and batches, technical data sheets, drying conditions, the ratio of colored mothers and respirators, specifications of equipment to screws, product and fluid weight, the temperature of the moulds and existing defects. For products with multiple cavities or thin differences, the weight of the cavities should also be compared with the critical dimensions to prevent averages from covering up local problems. The main risk of the subject is that the parameters will be applied only by the name of the same material, and that there will be under-charging, overheating or periodic lengths due to the different sizes of the card. 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. When twisting, measuring time changes at the same time as the actual melting temperature, the material, feed and wear should first be sorted out and not compensated by an increase in temperature alone. 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.

To verify how “polymers molecules affect melting strength and mobility”, it is suggested that replicable methods should be used: checking card number technical data, melting index, pressure curve, twisting and melting line strength. The final evaluation should be based on the unit eligible cost, incorporating scrap, clean-up, energy consumption, stop and screw-breeding. 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.
