“The temperature of the material drums should be set according to the material melting process” is often valued after the defects in the product have occurred, but it is more effective to establish a test boundary before testing. The key mechanism for this theme is that temperate areas need to be combined with feed, compression and measurement processes, with a set value not equal to the actual temperature of the material. Melting viscosity is influenced by both the temperature, shear rate, pressure and thermal history, and equipment values must be calibrated in measured state. 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 phase, an input list should be established around “the temperature of the material drums should be set according to the material melting process”, including feedstock suppliers and batches, technical data tables, drying conditions, the ratio of colored mothers to retrofits, specifications of equipment to screws, product and flow 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 risks of the subject are: overheating of the heating section to build bridges, unsmelting of the previous section, and increased degradation and salivation of the end-end overheating. 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. Anomalous analysis begins with a determination as to whether it occurs suddenly or slowly: the former is mostly related to pollution, carcasses or changes, while the latter often points to wear, retour and batch trends. 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 that “the temperature of the material drum should be set according to the material melting process”, it is suggested that a repeatable method should be used: measure the temperature of the material in each sector, twist it, measure the time and the temperature of the melting and adjust it by region. If the result is established only in a small number of samples, it should be extended to continuous production and cover shifts, patches and short stop start-ups. 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.
