The distinction between molds, processes and reversible rings under the issue of [scenario definition] fly-side is based on the actual production scene of the plant and cannot be based solely on the diameter of the screw or the price quoted. It is recommended that the frequency of defects, time periods and changes in process parameters be first sorted out and then that baselines be established for each of the three phases of start-up, stable production and refuelling. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The most easy to ignore on this topic is the boundaries of screws, cylinders, reversible rings and molds. The plant should break down the daily production into class beats, time available and model losses, and indicate variable and non-variable conditions in the demand table to reduce programme repetition. Vendors can make retroactive trade-offs between interoperability, earmarking and cost when there are clear values for product weight, daily production, customer quality caps and allowed stop times.

The main line of the case [design focus] is to pre-empt the causes of drying, temperature control and molds with evidence. In geometric and material programmes, the inner diameter and wear state of the cylinders should be integrated into the gap, so as to avoid new screws being dragged by old cylinders, while cutting the heat with gradual compression control and keeping sufficient corridors for gas escape. The final solution would also need to be compatible with the wear and tear of the cylinder, the drive, the physical velocity and the current cleaning process, and would not cover up co-operation or process problems with a single high-level material.

The new [comparison-valid] programme proposes to operate for at least eight consecutive hours, extracting 20 sims for each stabilization phase, recording extremely poor single modulus weight, storage time and bad black spot rates. The test shall be carried out in groups of samples of the head model, stabilization and long-lived operation for ease of comparison, while also measuring the temperature of the entropy and the temperature shown in the drums, confirming the contribution of the shearing. If only the first one is checked, it is easy to miss the risks associated with heat drifting, material stoppage, reversal loop return and prolonged wear and tear.

When the [stabilized production] spiral is shaped, trend maps should be created for the plume, the reverse ring gap and the inside of the cylinder, and inspection cycles should be developed for both running hours and tons of processed raw materials. The time of storage, back pressure, screw velocity, noise and mass of the product shall be recorded in a uniform manner in the shift. When the above indicators change at the same time, the mechanical gaps and the state of the raw materials should be checked before the process is adjusted to avoid the use of parameters to compensate for hardware degradation.

The [integrated cost] cost table should not be a single spiral price, and three life-cycle scenarios should be set with optimism, benchmarks and conservativeness to prevent a single hypothesis from magnifying the return on investment, and to calculate the cost of inventory, maintenance and rust-proofing for the back-up screw and then compare with the cost of emergency delivery. It is recommended that the cost per 10,000 eligible items be exported simultaneously, the cost per 1,000 operating hours and the estimated number of return months. When new programmes reduce waste, refuelling or sudden shutdowns, higher initial inputs are often offset during production.

The [Closed Ring Management] will eventually include drawing numbers, screwdriver materials, heat treatment, critical dimensions, portable tubes, process windows and acceptance data in the curriculum vitae cards. It is recommended that stratums by batch of raw materials prevent the miscalculation of formula fluctuations as a matter of equipment, and that trend maps be created for pyroclastics, anti-ring gaps and the inner diameter of cylinders. When there is a significant change in the feedstock formulation, retrospective ratio, product structure or target node, the applicable boundary of “how to distinguish between moulds, processes and causes of reversals under the fly side” should be reassessed, rather than defaulting that the old conclusion is permanent.
