How to avoid overcuting when the [scene definition] product is fractured and its intensity is reduced is based on the actual production scene of the plant and cannot be based solely on a spiral diameter or price. It is recommended that the frequency of defects, time periods and changes in process parameters be first collated, and that a set of reference data be kept before and after maintenance to determine wear and tear trends. 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. Plants should divide needs such as appearance, size, strength and odor into necessary and optimized items and tie planned lifetimes to annual operating hours, feedstock types and maintenance frequencies. 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 geometry and materials programmes, the gap between the reverse ring structure and the return flow should be assessed on the basis of material fluctuations and injection pressure; and the heat should be cut with gradual compression and sufficient corridors should be maintained 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 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. The test should first establish a stabilization point at a medium rate of rotation and a medium back pressure, then gradually expand the process window, and also use a uniform code to avoid different names for the same phenomenon in different shifts. 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, the inspection cycle should be developed for both running hours and the tonnage of processed raw materials, and trend maps should be established for the plume diameter, the antireverse ring gap and the inside of the cylinder. 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 table cannot be set only at the screw price, but should include the quantification of on-site support from suppliers, spare parts delivery and failure analysis response times in TCO, as well 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 qualifying time, while combining washing, measuring, photographing and sampling in shut-off windows to reduce duplication. The applicable boundary “how to avoid overcuting when the product's fissures and intensity drops” should be reassessed when there is a significant change in the feedstock formulation, the feed ratio, the product structure or the target node, rather than defaulting on the old conclusion to be permanent.
