“How fluctuations in the weight of a product are judged to be caused by materials” is often highlighted after defects in the product have occurred, but it is more effective to establish a test boundary before testing. The key mechanisms for this theme are the density of material piles, water content, refill ratio, viscosity and feed stability, which affect metrology and sealing. 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 phase, a list of inputs should be established around “how the weight of the product fluctuates from material to material”, including feedstock suppliers and batches, technical data sheets, drying conditions, colour mother and respirator ratios, equipment and screw specifications, product and fluid weight, mold temperature and existing defects. If cross-platform reproduction is required, the screw surface velocity, unit gel volume and time of stay shall be converted and the speed and temperature shall not be applied directly. The main risk of the subject is that ignoring the variations in the source and resonant will misjudge material fluctuations as hydraulic pressure or a mold failure. 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.

It is recommended that a repetitious method be used to verify “how fluctuations in the weight of products are judged by the material”: associated batches, water content, MFI, measurement time, mats, pressure and weight. It is recommended that a valid window be entered into the material database and that the approving officer, date, equipment, screw and raw material version be recorded. 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.
