[Scene definition] Why is the screw head component to be managed separately from the main screw to start from the real volume scene of the plant and not to read only the diameter or price of the screw? It is recommended that the filling content, corrosive media, temperature and operating hours be first collated and then stratified by batch of raw materials to prevent miscalculation of formulation fluctuations as a matter of equipment. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The easiest to ignore is the rate of wear and tear, the growth of the gap and the sudden failure. Plants should check the remaining plasticization capacity on the basis of order peaks rather than average annual production, and should use the Paletotot chart of customer complaints and internal end-of-life to determine priorities. 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 the selection of materials, thermal treatment and surface layer based on the wear and tear machine. In geometry and materials programmes, the base, alloy layer and surface treatment should be selected on the basis of grinding, corrosive and thermal loads; and the drive-and-cracker, the rate of rotation and the screw cores should be checked to prevent the production from increasing at the expense of mechanical safety. 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 72 consecutive hours, extracting 50 sims per stabilization phase and recording the number of downtimes, maintenance hours and the combined cost per 10,000 items. A planned refuelling test should be added to the test to check the consumption of residues, black dots and cleaning materials, while measuring the temperature of entropy and the temperature shown in the drums, confirming the contribution of 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 pyroclastic exterior, the reverse ring gap and the inner inside of the cylinder, and the abnormal twisting, storage time overtime and material rebounding should be set as an early overhaul signal. 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 [comprehensive cost] cost statement cannot be a screw price alone, and the costs of passenger litigation, return of goods and additional overhauls should be classified as loss of quality, not only as scrap by side, but also as quantified in TCO for on-site support from suppliers, spare parts delivery and failure analysis. 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 tiered measurements by batch of raw materials prevent the miscalculation of formula fluctuations as a matter of equipment, while preparing screw-head components or spare parts for key platforms and periodically reviewing their availability. When there is a clear change in the feedstock formulation, retrospective ratio, product structure or target node, the applicable boundary of “why screw head components should be managed separately from the main screw” should be reassessed, rather than defaulting that the old conclusion is permanently valid.
