The measurement of the impact of the diameter ratio of a journey to a spiral on the stability of plasticization begins with the placement of structural dimensions, material behaviour and actual production loads in the same logical chain. The core is to measure the ratio of the journey to the diameter of the screw, reflecting how much of the effective screw length is used per model. Short travel leads to a low rate of material updating and long journeys to a near limit for plasticization and feed and may lead to temperature differentials. The choice of diameter involves both reductive resolution, pressure capacity, plasticization, stop time and driver load and cannot be judged by product weight alone. The design evaluation is to distinguish between “scales can be installed” and “processes can be stabilized”, the former only resolve mechanical interfaces, and the latter relate to plasticization efficiency and product quality. Nominal specifications are therefore only the starting point, and the final conclusions must serve the actual resin, product and volume rhythm.

When customizing around "Measuring the impact of the diameter ratio of the journey to the screw on plasticization stability", first collects the size of the equipment model, the original screw and the material drum, the driving capacity, the resin plate number and the filling system, the single mass, the cycle and existing defects. The specific selection principles for the topic are that the product and flow weights, mats, melting density, cooling time and plasticization should be taken into account in the selection. If the device can export a curve, the original record of screw position, turn speed, twist, back pressure and time should be kept, so as to avoid only being assessed by the operator. The technical agreement should include quantifiable provisions for size benchmarks, key communications, material status and acceptance methods so that new, old and subsequent restorations can be compared under the same criteria.

The most needed to guard against the failure of the subject is that very short journeys are often accompanied by yellow changes and black spots, and that very long journeys are likely to have unmelted particles, undermeasurement and cycle extensions. When the size is still satisfactory and performance is abnormal, the same axiality, roughness of the surface, partial loss of coatings and thermal deformation are also examined and not only the outer diameter. For on-site processing, only one main variable is changed each time and the measurement time, twist, melting temperature, mat, injection pressure and product weight are aligned to the same pattern. If production is to be sustained by excessive temperature, turn speed or back pressure, the use of parameters to mask structures, wear or collage should be discontinued.

This replicable option can be used to validate the "Measuring the impact of the diameter ratio of the process to the screw on the plastic stability": The percentage of the journey, the actual time of stay, the plastic surplus and the weight fluctuations of the different batches are recorded under mass conditions. Receiving and inspection should not end when the equipment is not in thermal equilibrium, and should cover typical use links such as start-up, steady state, suspension of re-opening and refuelling. Inquiries to suppliers should also be accompanied by information on resins and fillings, risk of flame retardation or corrosion, total weight of products and fluids, photographs of available screws and equipment curves. The programme is considered to have a stable engineering value when the detection data, the good product rate, the timing of the switch and the unit cost of the eligible goods are improved.
