[Scene definition] Which end-of-pipe retrofitting mills are suitable to start from the actual production scene of the plant and cannot read only the diameter or price of the screw. It is recommended to first organize filling content, corrosive media, temperature and operating hours, and then follow three consecutive shifts to avoid single-temporal models representing the production status. 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 indicate variable and non-variable conditions in the demand table, reduce programme repetition and divide needs such as appearance, size, strength and smell into mandatory and optimized items. 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, gradual compression controls should be applied to cut the heat and sufficient corridors for gas escapes should be maintained; and the depth of the feeder slots should be checked for stable transport while avoiding feeder docking. 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] program proposes a minimum of 48 hours of continuous operation, with a 100-mode extraction for each stabilization phase, and records the screw-back load, back pressure stability and daily production. The test shall be conducted for a sufficient period of time under the normal upper load to observe the twist, temperature and measure drift, and at the same time to measure the temperature of the entropy and the temperature shown in the drums, confirming the contribution of the cut heat. 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.

The [stabilized production] screws should be shaped to create trend maps of the pyroclastic diameter, the reverse ring gap and the inner inside of the cylinder, and a maximum number of repairs should be set for the refurbishment to record the amount and thickness of each drop and surface layer. 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 simply be a screw price, and the cost of passenger litigation, return of goods and additional overhaul should be classified as loss of quality, not only as scrap by aircraft, but also as a minimum production threshold for dedicated screws, re-comparisoning the generic formula when production is insufficient. 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 proposed to establish a record of refuelling weights, cleaning time and first eligible time, while preparing screw-head components or spare parts for key platforms, and to review their availability on a regular basis. When there are significant changes in the feedstock formulation, retrospective ratio, product structure or target node, the applicable boundary of the “ordinary nitrogen snail suitable for which end-in-formation plants” should be re-evaluated, rather than defaulting on the permanent validity of the old conclusion.
